Description of the invention (5) That is, it displays the operation waveform of one sub-frame in the majority of sub-frames (consisting of six-frame sub-frames SF1 ~ SF6 in Figure 20). The sub-picture frame constitutes one of the so-called address / sustain discharge period separation type and write address method. According to the ratio, a sub-picture frame SF consists of at least three periods of the reset period S1, the address period S2 and the sustain discharge period S3 Composition; Among them, S1 period is just before redisplaying the image of the sub-frame frame, in order to eliminate the display (0N) state of each sub-circle frame in the previous frame, all YII poles are first made 0V At the same time, a write pulse (WP) made of voltage 1 is applied to the X electrode. Thereafter, the voltage of the female electrode 15 becomes Vs, and the voltage of the X electrode becomes 0V, thereby performing Sustain the discharge, in this state, perform a full write process, and apply blanking urea flush (EP) to the X electrode 14 to temporarily eliminate the stored information and the wall charge in all the unit parts 10. This period is Called the reset period S1. This reset period S1, regardless of the previous sub-frame ON Whatever the state, it has the effect of making all the units the same state; and has the purpose of not even starting to discharge even if the wall charge beneficial to the address is applied to the sustain pulse. The staff of the Central Ministry of Economic Affairs of the Ministry of Economic Affairs Printed by the cooperative (please read the precautions on the back before filling in this page) Secondly, in this case, after the subsequent period S1, there is an address period S2; and during the address period S2, in order to proceed In response to the display data, the unit is turned on / off (0N / 0FF), and the M line performs address release sequentially. First, the scan pulse SCP of 0V level is applied to the pole, while the address pulse ADP of the voltage V2 is selectively applied to a cell corresponding to the address gate that causes the maintenance of the sky (卽, for The address of 0N unit> is extremely high, and hereby is used to write and release the unit used for 0N. In this way, the Chinese national standard (CNS) Λ4 regulation is applied to the standard of this paper wave (: 2 丨 〇: < 29, mm) 9 A7 Β7 i, invention description printed by the employee consumer cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (6) The address between the pole and the selected pole produces a small discharge that cannot be directly perceived, so that a prescribed amount of charge Stored in the corresponding unit 10 to complete the writing (address) operation of the display line. Below, in turn, the same action is performed on the other display lines, and then, in the full display system, write new display data 0 Thereafter, when it becomes the sustain discharge period S3, the sustain urea punch formed by Vs is alternately applied to the Y electrode and the scratch to perform sustain discharge, and then the image display of each sub-frame is performed. Also, here address / sustain discharge separation type In terms of the address input method, the brightness of the display screen is determined according to the length of the period of maintaining the enlightenment, that is, the number of times the urea is maintained. Conversely, the lower the brightness. That is: as shown in the example of the sub-frame in Figure 20 * When using the sub-frame SF1 to perform the maintenance and release «operation, the brightness of the day surface becomes the darkest; otherwise, the sub-frame SF6 is used to When the sustain release operation is performed, the brightness of the display screen becomes the brightest. If the seed frame is properly combined to perform the sustain discharge operation, grayscale display with multiple gray levels can be performed, as shown in the example of M20. In other words, as shown in Figure 21, according to the combination method, 64 different gray levels can be displayed. Therefore, by adjusting the gray level of the brightness, from most kinds of sub-frame patterns (which are The number of sustain discharges of each sub-frame is set to a specified weight), the most suitable sub-frame pattern is selected, and the sustain discharge operation is performed in each sub-frame, and the synthesis result of these becomes the gray scale of 1 frame Wait Brightness.

Description of the invention (7) Although the reset period S1 and the address period S2 of each subframe SF1 ~ SF6 in the 20th ring have the same temporal length, the temporal length of the flying period S3 is maintained, However, it differs according to each sub-frame, for example: the number of sustain discharges from sub-frames SF1 to SF6 is set to 1: 2: 4: 8: 16:32, use the appropriate address to select the sub-frame Any one or more of SF1 to subframe SF6, by which the number of sustain discharges in one subframe can be changed appropriately. That is, according to the example in Fig. 20, the brightness combination of 0 to 63 gray levels can be performed by the selected combination of the sub-frames. Furthermore, although Fig. 20 illustrates an example of combining six subframes, the present invention is not limited to combining six subframes. For example, eight or four subframes may be used, and any combination may be used. In this way, the aforementioned address / maintaining separation type address method * is the most advantageous method in terms of the method of effectively utilizing the gray scale display of time by using the storage function of the AC type plasma skull display device PDP * Fig. 22 shows the display data control unit 36 and the plasma display unit (PDP) timing generation unit 74. The display data control section 36 is used to receive the display data of the CRT-1 / P signal, and then temporarily store the display data in the frame memory section 71 in advance. This is to separate the halftone data of the display data of the CRT-1 / F signal in the direction of the time axis. In this way, in order to divide according to the time axis direction, there are two frame memories that alternately write and commend every frame, so that the input data and the output data of the display data control unit 36 are prevented (A -DATA) Competing for writing and reading to the box memory section 71 in a hurry.

Description of the invention (8) That is, when writing to the frame memory A44, the frame memory B 45 is the reading operation. In Xi, 46 and 47 are line converters, which change the switching direction of the line according to the operating state stored in the frame. The display data pre-processing unit 43 is for the frame memory 71 A circuit that effectively praises address excitation data (A-DATA) and performs pre-processing for writing data to the frame memory section 71. The frame memory control circuit section 42 is derived from the P [) P timing generation circuit 74. The control signal M is used to generate the address multiple of the write / read address of the frame memory 71. The conversion of the write / read address signals of the frame memory portion 71 is performed by selectors (SEL) 48, 49. In addition, the conversion of the selectors 48 and 49 is performed by using the FTOG signal (signal inverting the logic per frame).

The RCA 1 signal is used to determine which subframe display data is to be praised. The PDP timing generation circuit part is determined by the I / F circuit part 70 and the subframe The forming mechanism 73 and the sub-frame counter 72 are formed. The I / F circuit unit 70 externally inputs unit control signals (Vsync, Hsync, BLAND, CLOCK>, thereby generating FCLR, FTOG, DWST signals. Sub-frame counter 72, reset by FCLR, and »SP The CLR is incremented. The sub-frame forming mechanism 73 executes the driving timing (ie, the timing of Sl, S2, and S3) in the sub-frame when entering the FCLR, and when the sequential timing ends, the SFCLR signal is output Then, the sub-face frame forming mechanism 73 uses the generation of the SFCLR multiple number to restart the driving timing in the sub-picture frame. Repeat this action until the number of sub-frames in the frame is executed a specified number of times. The driving timing S3 in the sub-frame, that is, the selection of the sustain pulse is determined by the value of the output RCA1 of the sub-frame counter. [Problems to be solved by the invention] As shown on the 20th, according to the conventional circle, the halftone is divided.

Description of the invention (10) Method, which consists of a large number of different brightness ratios (N-value) ) The sub-frames constitute a frame, and the sub-frames are appropriately combined to perform the display of 2N gray levels, but the ON sequence of the sub-frames is fixed in the predetermined order. To this end, display dynamic images When the analog signal source such as the video signal is converted by analog / digital conversion to display, the frequency of the plaque frame is usually a frequency that does not produce flicker (for example, 6 Hz), and a low frequency (display flicker frequency) component (30 Hz) becomes a partial flicker, resulting in problems such as reduced image quality and grounding. Figure 23 is a diagram used to illustrate the generation of flicker. If it is assumed that the sub-circular frame is composed as in Figure 20, each sub-frame Brightness ratio, Yidi dimension When the ratio of the release period is set to SF1: SF2: SF3: SF4: SF5: SF6 = 1: 2: 4: 8: 16: 16: 32, all subframes of SF1 to SF5 are turned on at the same time, thereby displaying the 31st (Grayscale) level, and only the SF6 frame 0N »is used to display the 32nd (Grayscale) level. In this case, when the display data alternately displays 31 levels and 32 levels, as shown in Figure 23 (1) As shown, the 0N state of each sub-frame is represented by 0. If X is OFF, it will become as shown in the figure, and the result is the stage of 64 (grayscale) level (that is, from the sub-frame SF1 to SF6 all at the same time as 0N ribs), which becomes equivalent to alternately 0N · OFF for every one frame, forming a low-frequency part between the two consecutive frames, resulting in significant flicker. As shown in 23_ (2), even if it is When the displayed data is shaken between the 15th and 16th levels, the influence of the low-frequency component also becomes larger, and M is equivalent to the brightness of the reference level. The ON and OFF states are artificially generated and become bright. This paper scale is suitable for 3 Chinese kneading.

For example, in the Japanese Patent Laid-Open No. 3-145691, it is proposed to arrange the sub-frame in the center of the 1 frame as much as possible. This is how to reduce this phenomenon. Although this document discloses a method of arranging the sub-frames of the highest brightness stage in the center of the 1 frame, and the sub-frames of the second and third high-brightness levels respectively arranged on both sides of the sub-frames, this method changes. The method has not been able to broadcast satisfactory effects until now. In addition, even if the sub-frames are arranged as described above, if the sub-frames that emit light at approximately the same brightness are separated by a distance, flicker is generated at the boundary, which hinders the display quality. The higher the brightness, the stronger the occurrence of this phenomenon; this phenomenon can be clearly observed with gray gradient, etc. "The principle of the problem is roughly the same as that illustrated in Figure 23. However, this phenomenon is caused by the small vibration of the eyeball, which causes the vibration of the image projected into the omentum, resulting in an overlap between specific gray levels on the omentum, and a flicker of 30 Hz. Therefore, in order to improve this flashing phenomenon, the light emission period of the uppermost sub-frame is divided into two, and the light-emitting period of the high-brightness sub-circle frame is doubled to the frequency of the nursery frame. ). However, the side of the sub-frame with dim brightness still flickers. The above-mentioned two Kang issues are caused by static images. The inventors of the present invention have found through experiments that, when displaying moving images *, there is a matter of disturbing midtones for reasons completely different from the above-mentioned two-tilt problem.

Description of the invention (12) When the gradient direction of the degree is rolled into a reel, bright lines or dark lines are generated between the held gray levels. The intensity of the light and dark lines and the gray levels are different depending on the direction of the roll or the arrangement of the sub-frames. Also, in a more specific example, when the color part of the character, such as a scorpion, moves, the color part produces a pseudo-like wheel of red, purple, or edge colors (this phenomenon is called a color pseudo-contour under K) > In particular, it becomes a problem when the dynamic circle image is displayed in color in the color display. Below, referring to FIGS. 24 and 25, the mechanism for generating the mid-tone disturbance in the dynamic image will be explained (the child in the frame will be The number of frames is set to 6). However, it is assumed that the pixels of blue (B), red (R>, and edge color (G) are sequentially arranged in this order, and the sub-frame frame system is assumed to be in accordance with SF6, SF5, SF4,... SF1 are arranged in this order. When the blue vertical, line subframe SF6 (uppermost subframe SF1) 0N is vortexed from right to down, it is displayed, for example, in the lffl frame When moving 1 pixel in the middle, it looks as if it is moving on the sub-pixels of other colors that are not ON, so the dynamics of the picture slip can be observed. This dynamic of the circle slip is even when the pixels moving to the 1 frame are quite large , Also observable. The field of psychology refers to this phenomenon as the fake lotus movement, or B movement Secondly, when the blue vertical one-line subframe SF6, 50N is used, and the display is vortexed from right to left as before, as shown in Figure 24, the luminous spatial ground of each subframe can be observed It is separated and displayed. The 24th circle is used to display the blue sub-frames SF6 and SF5, and it shows the viewing pattern of the generating unit when vortexing 1 image point from 1 V to 1 to 1 Vsync. Sub-frame SF6 The luminescence is displayed on the blue sub-pixel (B>, and under the same reasons as above, the paper is also applicable to the Chinese national standard (CXS Ί Λ4 specifications (ZΙΟΧ ϋ97 mm) (please read the notes on the back Please fill out this page again.) • Installed.

Invention description (13) It seems to move on pixels of other colors When the sub-frame SP5 turns on after the sub-frame SF60 is turned on, and the delayed display data is written for about 2 msec, under the false motion described above, the sub-frame under the vortex direction 6 Move sideways, making your eyes look like subframe SF5 The light catches up with the sub-frame SP6's light emission. Therefore, the sub-frame SF5 sub-light emission seems to be generated on the red pixel (R), resulting in a significant deterioration of the color viewing state. Similarly, when the When the sub-frame is ON and the vortex moves, as shown in Figure 25, the light emission of the sub-frames SF6 ~ SF1 looks as if they are spatially separated and emitted within 1 pixel. Figure 25 is used to display the blue child Frames SF6 ~ SF1, and the 1 Vsync 2 image point is from the right to the left when the vortex of the light unit's sightseeing state circle. In this case, the real light is: the interval between the sub-pixels becomes double * assuming The speed of the light of the lotus movement increases the distance of movement. Therefore, when the sub-circle frame F6 emits light and the sub-frame SF5 emits light with a delay of about 2 »sec, the light-emitting part of the sub-frame SF6 becomes moved further, which makes it seem that the space of the sub-circle frame is separated, that is The lighting interval seems to be wider. From the observation results, it is known that the spatial expansion of the sub-circumferential frame during the occurrence of the false motion is expanded to pixels that move within a period of 1 blue frame. Therefore, it is clear that the same sub-pixel should originally emit light, and the mid-tone is displayed according to the integration of the brightness of each sub-frame in the time direction of the light, but in the dynamic circle image part due to the sub-frames in the frame The luminescence is different from each other in space, and the brightness of the midtones cannot be expressed by the sum of the brightness of the sub-frames in the frame, so the turbulence of the midtone chromaticity is generated in the dynamic image section.窣 (CNS) Α4 regulations Luo (; Μ0 '< :: ι) ι mm --r ---- r ---- installed ------ order (please read the notes on the back before filling in (This page) -17 A7 B7 printed by the Employee Consumer Cooperative of the Central Department of Economic Affairs of the Ministry of Economic Affairs V. Description of the invention (14) Chaos. In a colorless display (white), this disorder is generated as a dark line or a bright line, and in a colored display, a color different from the original color is generated. In order to solve this problem, the applicant has disclosed the device and method for reducing the disturbance of mid-tone display in Japanese Patent Application Laid-Open No. 7-27 1325; it is by setting a majority of sub-frames with the same brightness, especially Set high-brightness sub-frames of two bows or three bows. When the value is two, it is set near the two sides of the one frame, and when it is three, it is set near the two sides of the one group frame and near the center. The combination varies with the gray level stage. It is suitable for luminous child circle frame to reduce the disorder of mid-tone display. In addition, the communique also discloses that two modes with the same sub-frame structure are set, and one of the modes prefers one of the sub-frames on or near the side where the light is initially emitted in a circular frame to make it glow. , And the wedge type of the other side prefers one of the sub-frames on or near the side where the light is radiated lastly in the frame of 1 and makes it glow. It is suitable to choose one of the two modes. This can reduce the mid-tone display. The disorder. However, according to this method, although the disorder of midtones can be greatly improved, it is still hoped for further improvement. The object of the present invention is to further reduce the disturbance of the halftone display in the time-sharing halftone display method in the frame and the time-sharing display device in the frame, thereby further improving the display quality. 〕 Di, the time-sharing halftone display method in the frame of the present invention, is composed of a plurality of bow units to display the display surface, and the data used to display each unit is rewritten for each frame, used during 1 frame The amount of light radiated from this unit is used to indicate the paper scale.

Description of the invention (15) Mid-tone display method among display methods that determine the brightness of each unit , That is, divide a frame into a plurality of sub-frames, combine a sub-circle frame that can emit light and a sub-frame that does not emit light, and the time-sharing mid-tone display method in the frame that displays mid-tones; its special features are: As mentioned earlier When the brightness of each sub-frame of the plurality of sub-frames is set to Νη, Νη-1, Νη-2 ··, Ν1 in order of decreasing brightness from the highest brightness, the aforementioned majority tilted subframes can be established as Nn = Nn- l + Nn-2 relationship. If there are many types of sub-frames, the sub-frames suitable for the second, third, and fourth luminances should be established as above. In addition, as long as the combination is effectively increased It can be effective if the above relationship cannot be established closely. For example, as long as the above general relationship is established, as long as the total brightness of the other two sub-picture frames exceeds the highest brightness sub-picture The brightness of the frame is sufficient. As disclosed in Japanese Patent Laid-Open No. 7-271325, two high-brightness sub-circular frames are provided so that these sub-frames are arranged near both sides of the 1 frame, and furthermore, two In order to reduce the disturbance of the mid-tone display, in other words, in order to improve the display quality, the following three elements must be required: (1) Make the sub-frames that can emit light smoothly arranged in the frame. ⑵ Disposal of radiation The weighted average of the sub-frames rarely changes, and the radiated light changes with the change of the displayed halftone stage. (3) Make the interval between the sub-frames that can emit light as small as possible. If you want to achieve this In fact, it is best to set up multiple sub-frames with the same brightness.

In the case of PDP, as mentioned above, each sub-round frame requires a reset period and an address period. When the dysprosium number of the sub-picture frame is increased, the ratio of the bit period to the address period increases after it does not help the brightness, so that the maximum device Brightness, that is, the display brightness when all the sub-frames ON is lowered. In addition, in order to increase the displayable gradation level, it is necessary to increase the brightness of the sub-picture frame. Therefore, the above-mentioned display quality and performance are in a trade-off relationship, and the problem is how to realize a combination that can satisfy both the display quality and the performance to a certain degree. According to the method disclosed in Japanese Patent Laid-Open No. 7-27 1325, it is to set the subframes of the maximum brightness and the second brightness of the majority, and arrange these subframes on both sides of the frame, in order to meet the above requirements . However, the brightness of each stage of the sub-frame is the same as the conventional one, which changes according to the harmonic multiplication of 2. The reverse view is printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. The time-sharing halftone display method in the frame of the present invention The sum of the brightness of the highest brightness sub-frame and the brightness of the second and third brightness sub-frames is made equal to the brightness of the highest brightness sub-frame, so that the combined health of the gray-scale stage can be achieved, efficiently increase. [Embodiment of the Invention] The following is an example in which the present invention is applied to a plasma display device, which is a representative example of a gas-discharge panel display device, and its configuration and operation will be described in detail with reference to the stub type, However, the present invention is not limited to the above embodiments.
