Description

A method and system for preventing 3D crosstalk of a display terminal

technical field

Embodiments of the present invention relate to the field of display technology, and in particular to a method and system for preventing 3D crosstalk of a display terminal.

Background technique

Three-dimensional (Three-dimension, 3D) display technology mainly obtains two images of the same object at different angles based on human vision, and transmits the left-eye image to the viewer's left eye and the right-eye image during playback. To the right eye of the viewer, the left and right eye images of people have a certain parallax, and the brain synthesizes the left and right eye images with time difference to form a three-dimensional effect. With the gradual progress of information technology, 3D display technology has become the most important part of display terminals, among which, 3D display crosstalk index (3D Crosstalk) is an important index to measure the image quality of liquid crystal display. Crosstalk is a situation where the light seen by one eye of the viewer is seen by the other eye to some extent, that is, the picture that originally entered the left eye is seen by the right eye, and the picture that originally entered the right is seen by the left, The phenomenon of "ghosting" appears.

Various parameters of the 3D display terminal cannot be ignored. In the prior art, in order to ensure the image quality of the display terminal in 3D state, parameters such as brightness, contrast, and backlight are adjusted. Active shutter 3D mainly achieves 3D effects by increasing the refresh rate of the screen. Generally, the brightness in 3D state is based on the premise of sacrificing the subjective image quality. Adjusting brightness by users will affect the crosstalk index of the display terminal; when the brightness When the adjustment is high, the crosstalk index of the display terminal will be too large, even exceeding the crosstalk index required by the product specification, and the phenomenon of "ghosting" will appear. Users cause different degrees of visual fatigue, which affects the user's actual viewing experience and comfort.

Therefore, the inventors found in the development stage of the display terminal of the 3D display technology that the crosstalk index of the display terminal is often a bottleneck. At present, many methods or devices related to testing or improving crosstalk have been proposed in business, most of which need to test the luminance values of the left and right eyes through external optical instruments such as digital screen luminance detectors, and then determine the crosstalk value according to the luminance values, and most of the methods are It is completed in the laboratory, and at the same time requires a large number of calculations, and the processing operation process is relatively complicated, with low efficiency and high cost. In addition, some physical methods such as replacing signal boards are used to improve the crosstalk index, which is costly, complicated to operate, time-consuming, and low in efficiency.

detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one:

Referring to FIG. 2, it is a flowchart of a method for preventing 3D crosstalk of a display terminal according to an embodiment of the present invention, including:

S110: Obtain multiple pixel luminance values of multiple pixel points of the picture in the 3D state of the display terminal, so as to determine the luminance value of the picture;

S120: When the brightness value of the picture is greater than a first preset value, generate a crosstalk value based on the brightness value of the picture;

S130: When the crosstalk value is greater than a second preset value, set a brightness parameter of the display terminal to any value within a brightness threshold range.

In the embodiment of the present invention, in order to avoid the influence of ambient light brightness, the method is selected to be performed in a dark room. The method is mainly used in the testing and inspection process of researchers to test the threshold range of the brightness parameter of the display terminal in the 3D state, or to check whether the brightness parameter of the display terminal in the 3D state meets the requirements of the product specification. If not, Then automatically set the brightness parameter in the display terminal to any value within the brightness threshold range.

It should be noted that the display terminal in the embodiment of the present invention may be a liquid crystal display terminal of any mode such as TN, LTN, PSS, and IPS. The picture in the 3D state of the display terminal in the embodiment of the present invention is input by an external instrument, including at least one of a left black and right white picture or a left white and right black picture (see Figure 1); the external instrument can be a driver device, such as a disc.

Embodiment two:

As shown in FIG. 3, it is a flowchart of an optional embodiment method in the method shown in FIG. A specific implementation method for determining the brightness value of the picture includes:

S111: Determine at least one brightness curve in the picture;

S112: Collect pixel luminance values of multiple pixel points along the luminance curve;

S113: Determine the brightness value of the picture according to the pixel brightness values of the plurality of pixels.

In the embodiment of the present invention, the 3D picture displayed by the display terminal is a static picture, and the picture includes brightness values of each sub-pixel. The path of the luminance curve and the pitch (such as 5 mm) and/or time (such as 1 s) of pixels in the collected luminance curve are preset. There can be one or more brightness curves. For example, the preset point collection path is a straight line running through the full screen of the display terminal left and right. When collecting points, the pixel brightness values of each pixel point on the curve are taken every 1s along the brightness curve, and the pixel point interval is 5mm.

Further, the display terminal area can be evenly divided in advance (for example, 12, two areas are symmetrical), and the area to be collected is selected, and the brightness value collection operation is performed on the selected area by using the brightness value collection device.

Furthermore, the collection of brightness values may be a photosensitive or sensing chip installed in the display terminal, so that the display terminal has the function of collecting the brightness value of the screen and extracting the brightness value, or it may be other methods known to those skilled in the art. Method.

Ideally, the luminance value of the white area should be the selected luminance value, and the luminance value of the black area should be 0; but in reality, crosstalk always exists, so the measured luminance value of the black area should be If it is greater than 0, the brightness value of the white area should be smaller than the set brightness value. In the embodiment of the present invention, the collected luminance values of the display terminal are directly processed without buffering, and when the luminance values of pixel points are collected, the current point collection operation is completed. The collected luminance values are processed to obtain a two-dimensional image related to the time and luminance value of the collected pixel point luminance values. Since the luminance value of the black area is smaller than that of the white area, the luminance value of the display terminal may be the average value of the luminance values of the white area in the luminance curve, or the average value of the luminance values of the white area in the luminance curve. The luminance value with relatively dense distribution may also be the average value of the luminance values of all pixels in the white area selected in the screen in the 3D state. The method for determining the brightness value of the display terminal is not limited to the above methods, and may also be other methods known to those skilled in the art.

Further, the number of operations for collecting brightness values may be preset (for example, 3 times), with a certain time interval (for example, 3s) between the operations. Comparing the luminance values obtained by the multiple operations, and selecting an intermediate value as the luminance value of the display terminal; or summing and averaging the luminance values obtained by the multiple acquisitions, and the obtained average value is the luminance value of the display terminal. The method for collecting luminance values multiple times can greatly reduce collection errors, making the finally obtained luminance values more accurate.

In the embodiment of the present invention, the provided method can automatically compare whether the brightness value is greater than a first preset value. The first preset value is determined by the brightness center point, for example, the brightness center point is 60, and the adjustable range is ±10, that is, the brightness threshold range is 50-70, and the first preset value at this time is 70; the brightness value Within the threshold range, there will be no crosstalk phenomenon, or the crosstalk caused is within the allowable range. If the brightness value (for example, 80) is greater than the first preset value, the phenomenon of "ghosting" of the 3D picture may occur.

In the embodiment of the present invention, when the brightness value of the display terminal is greater than the first preset value, according to the preset relationship between the brightness value and the crosstalk (such as a proportional relationship, the crosstalk value corresponding to the high brightness will also increase accordingly). large) determines the crosstalk value corresponding to the current brightness value. Before setting the relationship table between the brightness value and the crosstalk, it is necessary to measure the brightness value of the 3D picture separately according to the method of the prior art, and according to each picture (white on the left and black on the right, black on the left and white on the right, completely black) The brightness value below determines the crosstalk value. Due to differences in terminal hardware settings, the actual brightness values and corresponding crosstalk values of each display terminal are also different under the same brightness value. For example, when the brightness value is set to 60, 10 groups of presence Different luminance values will correspondingly obtain 10 different crosstalk values. According to these values, the luminance value range and the corresponding crosstalk range under the luminance can be determined; Brightness range) and the corresponding crosstalk value (crosstalk range), and finally these data can be directly retrieved and used. Therefore, after determining the brightness value of the current picture, the current crosstalk value and the corresponding crosstalk range can be directly queried in the table.

In the embodiment of the present invention, after obtaining the crosstalk value, it is automatically detected whether the crosstalk value is greater than a second preset value, where the second preset value is the maximum value of the crosstalk threshold range. For example, the preset crosstalk center value is 20%, and the allowable change range is 5%, then the crosstalk threshold range value at this time is 15%-25%, and the second preset value is 25%. If the crosstalk value is found to be 21% based on the determined brightness value, which is less than the second preset value, it means that the brightness change is only a fine adjustment, and the resulting crosstalk will not affect the image quality of the 3D state, and no adjustment is made. If the inquired crosstalk value is 30%, which is greater than the second preset value, it means that the 3D image quality crosstalk phenomenon caused by excessive brightness adjustment has affected the viewer's visual experience, and the brightness value needs to be adjusted.

Further, since the luminance value of the black area is not 0 due to crosstalk, the luminance value obtained in the black area can be directly used as a crosstalk value of the display terminal.

In the embodiment of the present invention, if the crosstalk value is greater than the second preset value, the brightness parameter of the display terminal is automatically set to any value within the brightness threshold range. Any one of the values is obtained according to a preset increment or decrement interval (such as interval 3). The interval 3 can gradually decrease to any value in the threshold range of brightness, which can be 68 or 62.

Further, after the brightness parameter is adjusted, the display terminal will display the adjusted 3D image.

The method provided by the embodiment of the present invention may be used for research and testing of brightness parameters of a display terminal, and may also be used for factory inspection of brightness parameters of a display terminal. Obtain the brightness value of the screen by processing the acquired brightness values of multiple pixels of the display terminal; detect whether the brightness value and/or crosstalk value exceeds the threshold range, if the brightness value is within the brightness threshold range (including the threshold), or When the brightness value is greater than the first preset value, but the crosstalk value corresponding to the brightness value is within the permissible crosstalk range, the brightness value is not adjusted; otherwise, the brightness value is automatically set to any value within the range of the brightness threshold. The method is simple to operate, does not need external instruments and equipment for measurement, and has no time limit for introduction, realizes real-time monitoring of the brightness of the display terminal, and can further detect whether the set brightness threshold range or crosstalk range meets product requirements, and realizes The real-time adjustment of the brightness value of the display terminal is realized, and the situation that the viewer's eyes feel uncomfortable or the visual effect is poor when the screen is too bright or too dark is avoided.

Embodiment three:

Referring to FIG. 4, it is a flowchart of another method for preventing 3D crosstalk of a display terminal according to an embodiment of the present invention, including:

S210: Obtain display parameters in the 3D state of the display terminal, so as to determine the brightness value of the display terminal;

S220: When the brightness value is greater than a first preset value, generate a crosstalk value based on the brightness value;

S230: When the crosstalk value is greater than a second preset value, set the display parameter of the display terminal to any value within a display parameter threshold range.

The method provided by the embodiment of the present invention is mainly applied to the phenomenon that the user uses the display terminal to adjust the parameters in the user menu of the display terminal, which directly or indirectly affects the brightness of the display terminal. The method can monitor and adjust the display parameters of the display terminal in real time, greatly reduces the phenomenon that the crosstalk exceeds the standard and affects the user experience, and also ensures the normal operation of the system.

It should be noted that the display terminal in the embodiment of the present invention may be a liquid crystal display terminal of any mode such as TN, LTN, PSS, and IPS. The display parameters are parameters in the TV user menu OSD (On-Screen Display), such as backlight, contrast, and brightness. Taking the contrast as an example, the user adjusts the contrast parameter to cause the contrast of the left-eye image and/or right-eye image on the screen to be too large, so that the brightness of the image viewed by the user's left eye is very high and the brightness of the right eye is very low, or the image viewed by the left eye The brightness is very low and the right eye is very high. At this time, the system will read the contrast configuration file of the display terminal to obtain the contrast value, and determine the brightness value of the display terminal according to the relationship between contrast and brightness (such as a functional relationship). In some cases, the user has fine-tuned the contrast parameter, but the brightness value of the display terminal has exceeded the brightness threshold range, which may cause "ghosting" in the 3D images watched by the user.

Further, the measurement of the brightness value includes the measurement of the brightness value of the environment and the brightness value of the display terminal, partitioning the display terminal (such as 12 areas), acquiring the brightness values of multiple pixels in the area and displaying them through statistical processing The actual brightness value of the terminal, the actual brightness value can be obtained by subtracting the brightness value of the environment from the brightness value of the display terminal.

In the embodiment of the present invention, the provided method will automatically detect whether the brightness value of the display terminal is greater than the first preset value. If the brightness value of the display terminal is less than or equal to the first preset value, it means that the change of the display terminal parameters has a greater impact on the image quality. If it is small, no adjustment will be made at this time; otherwise, it means that the change of the parameter is likely to cause the crosstalk in the 3D state of the display terminal to exceed the standard.

Further, when the brightness value of the display terminal is greater than the first preset value, then determine the corresponding crosstalk value according to the relationship between the brightness value and the crosstalk, and detect whether the crosstalk value is greater than the second preset value, if the crosstalk If the value is less than or equal to the second preset value, it means that the crosstalk caused by the change of the parameter at this time is within the allowable range, and the impact on the image quality of the 3D state of the display terminal is small, and the parameter is not changed; The resulting crosstalk exceeds the range required by the product specifications, and the phenomenon of "ghosting" appears on the 3D screen, which affects the user's visual experience.

Furthermore, if the crosstalk value is greater than the second preset value, the changed parameter will be automatically adjusted to any value within the threshold range corresponding to the parameter, and the adjustment method will automatically increase or decrease according to a preset interval. decrease.

In the embodiment of the present invention, both the first preset value and the second preset value are factory-set values, and the factory-set values may be the parameter values of the display terminal when it leaves the factory, or they may be comparative values measured by researchers during the research stage. The factory setting value has a more significant effect on the measured value. For example, the factory-set brightness can be adjusted from 50 to 70, and the brightness threshold range measured during the research and development stage is 50 to 72, and this result has been verified by multiple tests. It is determined that the brightness value of the display terminal will not cause crosstalk within this range. If the value is greater than the second preset value, then the factory setting at this time will be changed to 50~72; The value measured by the stage; if the two ranges are the same, no substitution is made.

The method provided by the embodiment of the present invention can be applied to places that need to use a display terminal, such as office and entertainment. The method can obtain the parameters in the user menu of the display terminal in real time, and apply different methods according to different parameters to obtain the actual brightness value of the display terminal; if the brightness value is within the set threshold range, or the brightness value exceeds the threshold range, but when the crosstalk value corresponding to the brightness value is within the permissible range of crosstalk, the changed parameters will not be adjusted; otherwise, the value will be automatically set to any value within the factory setting range, so as to realize the display of terminal parameters dynamic adjustment. The method has low cost and no time limit, and at the same time, it can avoid the situation that the change of the parameters causes the screen to be too bright, resulting in low 3D image quality, and the user feels that the visual effect is poor.
