Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display control method and device and a display device using the same, and more specifically, one frame of data to be displayed is composed of a plurality of subframes (screens) having different brightness. However, the present invention relates to a display control method and device for displaying gradation in a display screen by displaying the same in a time division manner, and a display device using the same.

In recent years, in computer displays, televisions, etc., the diversification of information to be displayed, the increase in screen size, and the high definition have been remarkable. Therefore, used in these,
Plasma display panel, LCD (Liquid Crystal)
Display), electroluminescence, fluorescent display tube,
In display devices such as light emitting diodes, it is required to improve the display quality in order to meet these trends.

As one method for this purpose, one frame in the data to be displayed is composed of a plurality of subframes (screens) having different luminances, and the subframes (screens) are displayed in a time-sharing manner to express gradation on the display screen. There is.

[0004]

2. Description of the Related Art Regarding this conventional method of expressing gradation, a case where a plasma display panel capable of color display (hereinafter referred to as PDP (Plasma Display Panel)) is used as a display device will be concretely described with reference to FIG. Explained.

As shown in FIG. 10, in the conventional gradation expression method, one frame is time-divided into a plurality of sub-frames. Specifically, for example, the screen rewriting is 6
If 0 Hz, the time corresponding to one frame is 16.
It will be 6 msec. Then, each sub-frame constituting the frame is time-divided into a reset period, an address period and a sustain period.

Here, the reset period is a period for resetting all the light emitting cells in the PDP to remove unnecessary charges. In the address period, a plurality of light emitting cells (one light emitting cell is one of the three primary colors of light (red, red,
It corresponds to one of the primary colors (green, blue). Of the above), a light emitting cell to emit light is designated based on the data to be displayed, and a pulse voltage (address pulse) is applied to the light emitting cell to emit light to temporarily emit light. Here, a straight line in the address period of FIG. 10 represents an address line, and the light emitting cells on each scanning line (one scanning line corresponds to one row of light emitting cells in the horizontal direction) indicate the address to which each scanning line corresponds. It is specified for a period on the line and is made to emit light temporarily. Further, in one address period, all the colors (red, green, blue) corresponding to each light emitting cell are targeted, and the light emitting cell is designated based on the data to be displayed.

The sustain period is a period for applying a pulse voltage (sustain pulse) for further causing the light emitting cell designated in the address period to emit light. The application time of one sustain pulse is, for example, 8 μm.
It is assumed to be sec. At this time, the more sustain pulses, the higher the brightness (brightness) in the light emitting cell. In this case, as described above, in one address period, the light emitting cells are designated for all the colors corresponding to the respective light emitting cells, and in the sustain period, all the light emitting cells (red, green, blue) are designated. The same number of sustain pulses are applied to each.

Next, in the case of gradation expression using the display data having the frame structure shown in FIG.
A case of expressing gradations will be described as an example. In the case of expressing the gradation of 64 gradations, “N” in FIG. 10 is 6, and the brightness of each sub-frame is brightness 1, brightness 2, brightness 4, brightness 8, in order from sub-frame 1. The number of sustain pulses is set so as to indicate the brightness 16 and the brightness 32. Then, for example, in the case of expressing 7/64 gradation, 7 (gradation) = 1 (gradation) +2 (gradation) +4 (gradation), and therefore corresponds to subframe 1 to subframe 3. The light is set to be emitted only during the period of time when light is emitted, and light is not emitted in other subframes. Also, for example, 2
In the case of expressing 0/64 gray scale, similarly, 20 (gray scale) = 16 (gray scale) +4 (gray scale), so that light is emitted only during the time corresponding to subframe 3 and subframe 5. Is set to.

Here, the brightness of each sub-frame in one frame is not always the same as that of the sub-frame 1 as shown in FIG.
It is not necessary to set the brightness in order from
The order of each subframe in one frame is arbitrary.

Therefore, in the gradation expression method of the prior art, as shown in FIG. 11 (b), the structure of one frame is not structured such that the luminance increases in order from the sub-frame 1, but Subframe 1 (luminance 1), subframe 3 (luminance 4), subframe 5 (luminance 16), subframe 6 (luminance 32), subframe 4 (luminance 8), subframe 2 (luminance 2) There is. As shown in FIG. 11A, when the luminance is increased in order from the sub-frame 1, for example, as shown in FIG.
When sub-frame 6 is turned on to express 32/64 gray levels in frame A shown in (a), and then sub-frames 1 to 5 are turned on to express 31/64 gray levels in frame B Since the human vision cannot temporally distinguish the sub-frame 6 of the frame A and the sub-frames 1 to 5 of the frame B from each other, they have one gradation (6
It is recognized as expressing 4/64 gradations. Therefore, as shown in FIG. 11A, on the display data, although the gradation difference is not large due to the continuous 32/64 gradation and 31/64 gradation, it is actually 64/6.
4 gradations (the brightest gradation) and 0/64 gradations (the darkest gradation) are recognized as being continuous, and so-called gradation distortion occurs. Therefore, in order to eliminate this gradation distortion, one frame is configured in the order of subframes as shown in FIG.

The gradation expression method described above is also applied to display devices other than PDPs. In this case, for example, in the case of a display device using a light emitting diode, the brightness is not changed by changing the number of sustain pulses, but by changing the voltage itself applied to the light emitting diode. It will be changed.

[0012]

As described above, in the conventional gradation expression method, in order to make the luminance of each color (red, green, blue) in one sub-frame the same, The number of sustain pulses applied was the same. More specifically, for example, in a sub-frame 1, if a sustain pulse of a number (a; natural number) is applied to a light emitting cell corresponding to red in order to have a brightness of 1, it corresponds to other green and blue. Similarly, a sustain pulse was applied to the light emitting cell.

However, in an actual PDP or the like, the emission characteristics (display characteristics) of the phosphors are different for each of red, green, and blue. Therefore, when the same sustain pulse is applied to the phosphors, there is a difference in visual chromaticity. There was a problem that was generated.

Further, the same sustain pulse is generated due to a difference in light emission characteristics due to manufacturing variations in the PDP (more specifically, for example, uneven coating of fluorescent material in each light emitting cell, uneven thickness of fluorescent material, etc.). There is also a problem in that when applied, non-uniformity in brightness occurs for each PDP.

Therefore, the present invention has been made in view of the above problems, and an object thereof is to prevent visual difference in chromaticity even when the phosphors corresponding to respective colors have different emission characteristics. Another object of the present invention is to provide a display control method and device capable of correcting non-uniformity in brightness even if the light emission characteristics differ due to manufacturing variations, and a display device using the same.

It is composed of a panel drive control unit 21 as a display control means.
Here, the display data control unit 20 and the panel drive control unit 21
Exchange necessary data with each other.

Further, the display data control unit 20 has a frame memory 30 for temporarily storing the input display data DATA one frame at a time and a display characteristic of the phosphor F corresponding to each color in the three-electrode AC PDP 1 (light emission).

Next, the operation of the display device S ₁ shown in FIG. 3 will be described with reference to FIGS. 4 and 5. First, the time division process of time division of the display data DATA in the display data control unit 20 into the subframe data SF _D will be described.

In the time division process in the display data control unit 20, as shown in FIG.
One frame in A is time-divided into luminance sub-frames SF ′ having different luminance, and each luminance sub-frame SF ′ has only one color of R, G and B as shown in FIG. 4B. It is time-divided into subframes SF corresponding to data. Here, each sub-frame SF has a reset period, an address period, and a sustain period, and three sub-frames SF (corresponding to each color of R, G, and B) corresponding to one luminance sub-frame SF '. The number of sustain pulses in the sub-frame data SF _D corresponding to is the same.

Next, the operation of the display device S ₁ in the sub-frame period corresponding to one sub-frame SF will be described based on the timing chart shown in FIG. Note that FIG. 5 shows the generation timing of each pulse in one subframe period.

As shown in FIG. 5, first, in the reset period, all the Y electrodes Y _{1 to} Y _N are set to 0V level, and further, the write pulse P _{XW is} applied to all the X electrodes X _{1 to} X _N. (About 330 V, 10 μsec) is applied. All address electrodes A ₁ are synchronized with this write pulse P _XW.
The write pulse P _AW is applied to A to A _M. All the X electrodes X _{1 to} X _N are _generated by the write pulses P _XW and P _AW.
And between the address electrodes A _{1 to} A _M (all light emitting cells C)
At, the discharge is performed regardless of the previous display state. Then, after the discharge by the write pulses P _XW and P _AW ,
All X electrodes X _{1 to} X _N and address electrodes A _{1 to} A
_M becomes 0V level, and in all the light emitting cells C, the voltage of the wall charge itself exceeds the discharge start voltage and the discharge is started. In this discharge, since there is no potential difference between the electrodes, wall charges are not formed, and the space charges self-neutralize and end, which is so-called self-extinguishing discharge. By this self-extinguishing discharge, all the light emitting cells C are brought into a uniform potential state without wall charges, and resetting is performed. In the reset period, all the light emitting cells C are in the same potential state regardless of the lighting state in the immediately preceding sub-frame period, so that the address discharge can be stably performed in the address period subsequent to the reset period.

Next, in the address period, the light emitting cell C to emit light based on the subframe data SF _D.
The address discharge for selecting is performed, and the wall charge is accumulated in the light emitting cell C to be emitted. This address discharge is divided into priming address discharge and main address discharge.

More specifically, first, priming address discharge is performed. In this priming address discharge, an address pulse P _AA is applied to the address electrode corresponding to the light emitting cell C to emit light, and in parallel with this, the Y electrode to the Y electrode corresponding to the light emitting cell C to emit light. A scan pulse P _AY is applied in a time-division manner (along the address line shown in FIG. 4B) sequentially from Y ₁ and is performed by the address pulse P _AA and the scan pulse P _AY .

A priming address discharge is generated between the X electrodes X ₁ and the Y electrode Y corresponding to the priming address discharge.
_The main address discharge occurs between ₁ and ₁ . Due to this address discharge, the MgO film 3 covering the X electrode and the Y electrode (X electrode X ₁ and Y electrode Y ₁ ) corresponding to the light emitting cell C to be made to emit light.
(Refer to reference numeral 3 in FIG. 2), the amount of wall charges capable of sustaining discharge in the next sustain period is accumulated.

The above-mentioned address discharge is caused by the scan pulse P.
Data is sequentially written to all the Y electrodes at the timing of _AY , and data is written to the light emitting cells C corresponding to the subframe data SF _D.

Finally, in the sustain period, all the X electrodes X _{1 to} X _N and the Y electrodes Y _{1 to} Y _N are alternated in order to further emit light from the light emitting cells C in which the wall charges are accumulated in the address period. Sustain pulse (about 18
0 V) is applied, and sustain discharge is performed in the light-emitting cell C in which the wall charge is accumulated, exceeding the threshold value, and image display of the luminance corresponding to the subframe data SF _D is performed.

Next, the designation step of designating the sub-frame SF to be made to emit light in the brightness level control section 31 will be described. As described above, in FIG. 4B, the subframe SF of each color corresponding to each luminance subframe SF ′ (for example, the symbols RSF1 and GS in FIG. 4B).
In F1 and BSF1), the number of sustain pulses is the same, and the luminance sub-frames S having different luminances are used.
In the subframe data SF _D ′ corresponding to F ′, the number of sustain pulses corresponding to each luminance is set. For example, the number of sustain pulses corresponding to the subframe RSF3 in FIG. 4B is three times the number of sustain pulses corresponding to the subframe RSF1.

Here, in the first embodiment, when there is a difference in the emission characteristics of the phosphors F corresponding to the respective colors of R, G and B, the difference is removed and the difference in visual chromaticity is reduced. The sub-frame SF to emit light is designated so as to be removed.

More specifically, for example, when the emission color of the phosphor F corresponding to G (green) is darker than other colors,
Subframe RS corresponding to luminance 1 in the other color
Even when F1 and BSF1 are designated, in the subframe SF corresponding to G, the subframe GSF3 indicating luminance 3 is designated, and these subframes RS
Each driver or the like is controlled as a subframe SF to be emitted by F1, BSF1 and GSF3. In order to specify these sub-frames SF to emit light, the correction data corresponding to the difference in the emission characteristics of the phosphor F is held in advance in the brightness level control unit 31, and the chromaticity for visual recognition is set based on the correction data. It is done so that there is no difference.

As described above, according to the first embodiment, even if there is a difference in the emission characteristics of the phosphors F corresponding to the respective colors of R, G and B, this is visually recognized according to the difference. Since the sub-frame SF to be emitted is designated for each color so as to be corrected, it is necessary to correct and display the luminance for each color according to the variation in the emission characteristics of the phosphor F in the three-electrode AC PDP. It is possible to eliminate the difference in visual chromaticity. (III) Second embodiment Next, claims 1, 3, 4, 6, 7, 9, 10, 12, 1
A second embodiment corresponding to the invention described in 3 and 14 will be described with reference to FIGS. 6 to 8.

As shown in FIG. 7, in the second embodiment, in the display data control unit 20, one frame in the display data DATA is color information corresponding to R, G and B as shown in FIG. 7A. And each of the three sub-frames SF having the same luminance as one group are time-divided so that the luminance changes in each group in the order of correcting the gradation distortion (see FIG. 11). .

After that, as shown in FIG. 7B, the number of sustain pulses as the luminance information in the three sub-frames SF corresponding to one luminance (the same among the three sub-frames SF) is Based on the correction data D _E stored in the correction memory 31A, the correction is performed in the sustain pulse number control unit, and the corrected luminance information D _R is output to the panel drive control unit 21.

More specifically, for example, when the number of sustain pulses is the same, due to the difference in the emission characteristics of the phosphor F,
When the brightness of the light emitting cell C corresponding to G becomes bright and the brightness of the light emitting cell C corresponding to B becomes dark, FIG.

Then, each driver is driven by the panel drive control unit 21 based on the number of sustain pal that is different for each color as the corrected luminance information D _R , and each light emitting cell C is driven.

Since the number of sustain pulses is corrected for each color in the sub-frame data SF _D corresponding to each sub-frame SF having the same brightness, the sub-frames SF having the same brightness are regarded as one set and visually recognized without changing the order. It is possible to eliminate the difference in chromaticity.

Although the correction memory 31A is configured to store the correction data D _E relating to the difference in the light emission characteristics for each color, in addition to this, the light emission due to the manufacturing variation of the three-electrode AC type PDP 1 is performed. When the characteristics are different, it is also possible to store the correction data D _E ′ relating to the unevenness of the brightness due to the variation in the correction memory 31A as well, and thereby to correct the brightness for each three-electrode AC PDP 1. .

More specifically, as shown in FIG. 8, the relationship between the number of gradations and the luminance is measured in an arbitrary three-electrode AC PDP1 manufactured in one manufacturing lot, and the measured value and the standard value are measured. The difference between and is stored in the correction memory 31A as correction data D _E ′ relating to uneven brightness due to manufacturing variations, and the number of sustain pulses is corrected based on this.

According to this structure, in addition to the effect of the second embodiment described above, when the light emission characteristics due to manufacturing variations are different, and when the unevenness occurs in the brightness of each of the three-electrode AC type PDPs 1. However, it is possible to correct the nonuniformity of the brightness.

If there is no difference in the emission characteristics of the phosphors F, only the correction data D _E ′ relating to the uneven brightness is stored in the correction memory 31A in order to correct only the manufacturing variations. It goes without saying that it is good. (IV) Third Embodiment Next, claims 1, 3, 4, 5, 7, 9, 10, 11, 1
