The communication protocol is an I2C protocol, SPI protocol, serial port protocol or proprietary protocol.

It should be noted that this is to clearly explain the content of this application plan. The production scenario of traditional display components is now explained.

In traditional production scenarios, the display components produced by the display component manufacturer will have a Tcon board (TimingController, timing controller, PCB board (Printed Circuit Board, circuit board) required for the LCD panel). Among them, There will be GammaIC on the Tcon board. Therefore, for manufacturers of display components, they only need to pre-store the adapted gamma voltage in the corresponding GammaIC when producing display components. But in the non-standard display device production scenario where GammaIC and display components are combined by themselves. When the display component and GammaIC are produced separately, for example, the display device manufacturer adapts the screen configuration of TconLess, where TconLess refers to the SoC (System-on-a-Chip, main chip) where the Tcon board or GammaIC is integrated into the display device. situation. Normally when a display device manufacturer produces a display device, the display components of the display device may come from different display component manufacturers, while the SoC of the display device is independently developed by the display device manufacturer. Therefore, it is easy for the gamma voltage to be inconsistent with the display component. The matching situation causes the terminal display equipment manufacturer to fail to adjust the automatic white balance of the display screen, resulting in defects in the display screen. Therefore, in response to the above problems, this application proposes a gamma voltage control method for display devices. The display device sets different gamma voltages according to different display components, thereby achieving the goal of adapting the gamma voltage to the display components and ensuring that the display components can display normally. picture.

Referring to Figure 2, there is a first embodiment of a gamma voltage control method for a display device of the present application. The display device includes a display component and a gamma voltage correction unit. The gamma voltage control method for a display device includes:

Step S10: Obtain the first gamma voltage data pre-stored in the display component and adapted to the display component;

It should be noted that in this embodiment, the display device includes a display component and a gamma voltage correction unit. In addition, the display device also includes a control component, which may be an SoC, and a gamma voltage correction unit may be integrated on the control component. Refer to Figure 3, which is a schematic diagram of the interaction between the main chip SoC, the gamma voltage correction unit and the control components in this application. The implementation subject of the above gamma voltage control method for a display device may be a display device or a control component in the display device. In order to explain this solution clearly, the control component is taken as an example.

For example, the control component communicates with the display component after being powered on and obtains the pre-stored first gamma voltage data from the display component. Usually, the gamma voltage adapted to the display component is adapted by the corresponding display component manufacturer, and the relevant data of the gamma voltage will be stored in the flash memory of the display component by the display component manufacturer. For example, referring to Figure 3, the main chip SoC (control component) will read the relevant data of the gamma voltage from the flash memory in the display component through an agreed protocol, that is, the above-mentioned first gamma voltage data.

In a feasible implementation, the display device further includes a control component, and the first gamma voltage data is transmitted through a communication protocol between the control component and the display component. The communication protocol is an I2C protocol, SPI protocol, serial port protocol or private protocol.

For example, the above-mentioned control component may be the main control chip SoC of the display device, the first gamma voltage data may be transmitted through a communication protocol between the control component and the display component, and the communication between the control component and the display component The protocol may be an agreed protocol, such as I2C (Inter-Integrated Circuit, bus) protocol, SPI (SerialPeripheral Interface) protocol, serial port protocol or other private protocols.

Step S20, convert the first gamma voltage data into target gamma voltage data matching the gamma voltage correction unit;

It should be noted that the gamma voltage correction unit will store relevant data of the gamma voltage, but the relevant data is usually the digital signal data of the gamma voltage. Among them, the specific voltage value of the gamma voltage is an analog signal. Therefore, the gamma voltage There is a digital-to-analog mapping relationship between the relevant data and the gamma voltage. The mapping relationship may be different for different gamma voltage correction units. Therefore, to ensure that the gamma voltage finally output by the gamma voltage correction unit is accurate. The first gamma voltage data obtained from the display component can be converted through different digital-to-analog mapping relationships to obtain target gamma voltage data that matches the gamma voltage correction unit.

In a feasible implementation, the step of converting the first gamma voltage data into target gamma voltage data matching the gamma voltage correction unit includes:

Step S210: Generate a first gamma voltage represented by the first gamma voltage data through the first data mapping relationship of the display component, wherein the first data mapping relationship represents the first gamma voltage in the display component. The relationship between ma voltage data and gamma voltage;

Step S220: Map the first gamma voltage to the target gamma voltage data through the second data mapping relationship of the gamma voltage correction unit, where the second data mapping relationship represents the gamma voltage data. The relationship between the second gamma voltage data and the gamma voltage in the voltage correction unit.

It should be noted that manufacturers of display components and manufacturers of display equipment usually do not unify the gamma voltage correction units, and in practical applications, it is difficult to unify the two. However, the manufacturer of the display component can inform the relationship between the first gamma voltage data and the gamma voltage stored in the display component, for example, the relationship between the first gamma voltage data and the gamma voltage, or That is, the first data mapping relationship is stored in the display device. The first data mapping relationship can be a calculation formula. By inputting the first gamma voltage data into the calculation formula, the gamma voltage can be obtained. The first The data mapping relationship may also be a mapping table, through which the gamma voltage corresponding to the first gamma voltage data is determined. Therefore, the first gamma voltage represented by the first gamma voltage data can be generated through the first data mapping relationship. Similarly, the second data mapping relationship can represent the relationship between the second gamma voltage data and the gamma voltage in the gamma voltage correction unit, and the relationship between the second gamma voltage data and the gamma voltage in the gamma voltage correction unit. Relationships can also be calculation formulas or mapping tables. Therefore, the first gamma voltage mapping can be converted into target gamma voltage data adapted to the gamma voltage correction unit through the second data mapping relationship.

Step S30: If the target gamma voltage data does not exist in the gamma voltage correction unit, write the target gamma voltage data into the gamma voltage correction unit so that the gamma voltage The correction unit outputs a gamma voltage to the display component based on the target gamma voltage data.

For example, the target gamma voltage data does not exist in the gamma voltage correction unit. The control component will write the target gamma voltage data into the gamma voltage correction unit, so that the gamma voltage correction unit can output the gamma voltage to the display component based on the target gamma voltage data, thereby ensuring that the gamma voltage correction unit The gamma voltage output by the display component matches the display component. For example, referring to Figure 3, the main chip SoC will write the target gamma voltage data to the gamma voltage correction unit, and the gamma voltage correction unit will write the gamma voltage to the display component based on the target gamma voltage data.

In a feasible implementation, before writing the target gamma voltage data into the gamma voltage correction unit, the method includes:

Step S310, determine whether the second gamma voltage data is pre-stored in the gamma voltage correction unit according to the unit type of the gamma voltage correction unit;

Step S320, if the second gamma voltage data is not pre-stored in the gamma voltage correction unit, determine that the target gamma voltage data does not exist in the gamma voltage correction unit;

Step S330, if the second gamma voltage data is pre-stored in the gamma voltage correction unit, determine whether the second gamma voltage data and the target gamma voltage data are the same;

Step S340: If the second gamma voltage data and the target gamma voltage data are not the same, it is determined that the target gamma voltage data does not exist in the gamma voltage correction unit.

For example, before writing the target gamma voltage data into the gamma voltage correction unit, it is determined whether the target gamma voltage data exists in the gamma voltage correction unit. First, it is determined according to the unit type of the gamma voltage correction unit whether there is pre-stored gamma data (ie, second gamma voltage data) in the gamma voltage correction unit. For example, based on the unit type of the gamma voltage correction unit, search from the mapping table between the unit type and the pre-stored condition whether there is pre-stored gamma voltage data in the gamma voltage correction unit. If it is determined according to the unit type, there is no pre-stored gamma voltage data. If the gamma voltage data (ie, the second gamma voltage) is pre-stored, it can be directly determined that the target gamma voltage data does not exist in the gamma voltage correction unit. On the contrary, if it is determined that the second gamma voltage data is pre-stored in the gamma voltage correction unit, the second gamma voltage data will be further read from the gamma voltage correction unit. As shown in Figure 3, the main chip SoC will read the second gamma voltage data from the gamma voltage correction unit. The voltage correction unit reads the second gamma voltage data. And determine whether the read second gamma voltage data and the target gamma voltage data are the same. If not, it is also determined that the target gamma voltage data does not exist in the gamma voltage correction unit.

In a feasible implementation, after the step of determining whether the second gamma voltage data and the target gamma voltage data are the same, the method includes:

Step S40: If the second gamma voltage data is the same as the target gamma voltage data, control the gamma voltage correction unit to output a gamma voltage to the display component based on the second gamma voltage data. .

For example, if the second gamma voltage data and the target gamma voltage data are the same, there is no need to write the target gamma voltage data into the gamma voltage correction unit. The gamma voltage correction unit can be directly controlled to output the gamma voltage to the display component based on its own pre-stored second gamma voltage data. At this time, the output gamma voltage is also adapted to the display component.

In a feasible implementation, the step of writing the target gamma voltage data into the gamma voltage correction unit includes:

Step S301: If the second gamma voltage data is not pre-stored in the gamma voltage correction unit, write the target gamma voltage data into the gamma voltage correction unit;

Step S302: When the second gamma voltage data is prestored in the gamma voltage correction unit and the second gamma voltage data is different from the target gamma voltage data, erase the first gamma voltage data. After obtaining the gamma voltage data, the target gamma voltage data is written into the gamma voltage correction unit.

Exemplarily, when the target gamma voltage data is written into the gamma voltage correction unit, it can be divided into various situations, for example, the situation where the second gamma voltage data is not pre-stored in the gamma voltage correction unit, At this time, the target gamma voltage data can be directly written into the gamma voltage correction unit. However, if the second gamma voltage data is pre-stored in the gamma voltage correction unit, and the second gamma voltage data is different from the target gamma voltage data, it is necessary to first store the second gamma voltage data in the gamma voltage correction unit. The second gamma voltage data is erased, and then the target gamma voltage is written into the gamma voltage correction unit.

In this embodiment, the display device includes a display component and a gamma voltage correction unit, and the control component in the display device will obtain the first gamma voltage data prestored in the display component that is adapted to the display component; The first gamma voltage data is converted into target gamma voltage data matching the gamma voltage correction unit; when the target gamma voltage data does not exist in the gamma voltage correction unit, the The target gamma voltage data is written into the gamma voltage correction unit, so that the gamma voltage correction unit outputs a gamma voltage to the display component based on the target gamma voltage data. That is to say, in the embodiment of the present application, the control component first obtains the first gamma voltage data in the display component that is adapted to the display component, and then converts the first gamma voltage data to obtain the gamma voltage correction unit matching the first gamma voltage data. Target gamma voltage data, secondly, the target gamma voltage data is analyzed through the gamma voltage correction unit to obtain the correct gamma voltage, and finally the target gamma voltage data is written to the gamma voltage correction unit, so that the gamma voltage is corrected The unit can output the correct gamma voltage to the display component through the target gamma voltage data. It can be understood that since the gamma voltage output by the gamma voltage correction unit to the display component is ultimately determined by the first gamma voltage data carried by the display component itself, it can be ensured that when different display components are used for assembly to obtain a display device, The gamma voltage output by the gamma voltage correction unit is always compatible with the display component, thereby improving the stability of the display component's picture output and reducing the possibility of display defects.

Referring to FIG. 4 , a second embodiment of the present application is proposed based on the first embodiment of the present application. In this embodiment, the same parts as the above implementation can be referred to the above content, and will not be described again here. The display component also stores a pre-stored check code of the first gamma voltage data and a check algorithm corresponding to the pre-stored check code. The acquisition of the pre-stored check code in the display component is consistent with the display component. The steps for adapting the first gamma voltage data include:

Step A10, read data from the preset storage area in the display component;

Step A20: Calculate the read data based on the verification algorithm to obtain calculation results;

Step A30: If the calculation result is the same as the pre-stored check code, use the read data as the first gamma voltage data.

It should be noted that the first gamma voltage data obtained from the display component is the basis for the gamma voltage correction unit to output the gamma voltage. Therefore, the accuracy of the obtained first gamma voltage data needs to be ensured.

Exemplarily, the display component will also store a pre-stored check code of the first gamma voltage data, and a check algorithm corresponding to the pre-stored check code, that is, the above-mentioned pre-stored check code is a verification algorithm for the first The result of calculation using gamma voltage data. When the display component manufacturer writes the first gamma voltage data into the display component, the display component manufacturer can also write the result of calculating the first gamma voltage data through the verification algorithm. After the control component reads the data from the preset storage area in the display component, it can calculate the read data through the above-mentioned verification algorithm to obtain the calculation result. The calculation result is then compared with the pre-stored check code. If the two are the same, the read data is used as the first gamma voltage data. On the contrary, if the two are not the same, it means that there may be errors in the read data, and an error message will be output. This avoids converting, analyzing and outputting erroneous data to the display component, causing the gamma voltage to not match the display component. In addition, it should be noted that the above verification algorithm can be CRC (Cyclic Redundancy Check, cyclic redundancy check), md5 (MessageDigest Algorithm, message digest algorithm fifth edition), hash128 (128-bit hash algorithm) and other algorithms .
