[Prior Art] The current flat-panel display industry is booming, display technology is new and new, and φ liquid crystal display (LCD) is on the scale of mass production, but other display technologies, such as plasma. Plasma Display Panel (PDP), Organic Light Emitting Diode (OLED) panels, and even Field Emission Display (FED), etc., each have advantages over LCDs, such as self-illumination. Fast response, high contrast, high color saturation, flexibility and many other advantages bring a considerable degree of threat to the LCD industry. In order to maintain the existing competitive advantages of LCD display technology, we have invested in R&D resources and manpower to enhance the tradition. LCD performance and display _ quality 'Field-Sequential Full-Color' technology, in improving the transmission, LCD bottleneck, such as improving system color gamut and saturation, reducing material formation, especially can greatly improve The electro-optical conversion performance of the panel system meets the requirements of the product. Field-sequence full-color liquid crystal displays do not require filters, and each pixel does not need to be subdivided into sub-pixels. Its color formation ^ = Color Sequential Method must rely on back 2) The primary color light source is switched according to the time series, and the liquid crystal pixel transmittance is synchronously controlled in each color light source to adjust the primary color = knowledge = color and then the integral effect of the visual system on the light stimulation to form and observe 5 200847095 A liquid crystal display panel that drives a liquid crystal pixel by a conventional color sequential method produces a timing diagram of three consecutive color fields. In a single color color frame period, a red pixel data is written first. Bright red backlight, forming a red field to display red pixel image data, then writing green pixel data, then lighting the green backlight to form a green field to display green pixel image data, and then writing blue pixel data, and then Lights up the blue backlight to form a blue field to display blue pixel image data. The three consecutive color field time light stimuli are incident on the ginseng eye 'light ray system' to form a color frame. The ideal imaging condition is that each pixel of the three image color fields contained in a color image is projected to the same position corresponding to each pixel on the retina, and the color information of each pixel can be visually and completely reproduced. . If the two image color fields contained in a color image are projected on different positions on the retina and are visually recognized by the visual system, the observer will see the image in which the color field is dislocated. This is called color separation (Color). Breakup, CBU) phenomenon, because CBU usually forms a ribbon arrangement at the edge of the object in the image, like a rainbow, so CBU is also called rainbow effect. In addition to reducing the viewing quality, the phenomenon of color separation may cause dizziness after watching the full-color display of the field sequence for a long time. Color separation The position of the corresponding pixels of each color field is projected to different positions of the retina and is perceived by the observer. Therefore, color separation usually occurs on the screen, and there is a relative motion relationship between the image and the retina, and color separation usually occurs in the direction of motion. There is a relative motion between the image and the retina, which can be divided into two conditions, each corresponding to different eye movements, one is a still image, and the other is a motion image. When the observer looks at the static face, the eyeball is not in a completely static state as expected, and conversely, the eyeball produces a saccade. This type of motion is extremely fast and disorderly, and 200847095 has the opportunity to focus on different positions in the continuous color field time, resulting in continuous color field separation. However, in the case of still images, since the jump is regarded as disordered motion, the color separation result is more difficult to predict. As for the observation of the motion picture, as shown in the second A picture, the main eye movement is consciously tracking along the direction of the object movement, so that the position of the corresponding pixel of each color field is projected to different positions of the retina, and observation There is thus a greater opportunity to perceive the presence of color separation fringes, as shown in Figure B. There are several ways to improve the color separation: 〗 〖 Increase the speed of the display component, such as increasing the color field frequency, reducing the color field time, equivalent reduction; Face, the color separation stripe is mixed with the inserted color field, reducing the contrast of the color stripes to reduce the visual system awareness = chance; 3) changing the color field order, changing the color field order in each image arbitrarily, making the color The order of separating the stripes is no longer fixed, that is, destroying the periodicity of the color separation fringes and reducing the degree of attention; 4• Dynamic surface compensation, ^ moving objects on the surface, as a reference for assuming the moving speed of the eye, The content of the face and the speed of the eyeball adjust the content of each color field image so that the viewer can reduce the relative motion between the color field of the eyeball and the face during viewing to reduce the color separation fringes. In the field sequential full color display, the color separation phenomenon is extremely difficult to eliminate when the response rate is limited. It is only possible to try to make the color separation effect as far as possible perceived by the observer. SUMMARY OF THE INVENTION The invention provides a field sequential full color display driving method, which divides the display area of the eight TO into two sub-display areas (sub-display a=, ea), and makes the foregoing The two sub-display areas are respectively displayed by different pixel groups and during the color image period (〇ne monochrome color frame 200847095 period), the color difference method (c〇l〇r Sequential Method) interactively displays the difference of the two sub-display areas. The color pixel data is such that when displaying the pixel data of each of the foregoing sub-display areas, the adjacent pixels of each pixel are in a dark state, thereby reducing the color breakup perceived by the observer's visual system. phenomenon.

The second step 536 'scans the νth scan line, the Ν+2 scan line, and the Ν+4 line to the field ·"··· to write the third pixel group data, for example, the green image group data. Next, in step 537, the pixel group is reset to eliminate the residual A, pixel image data. At step 538, the green backlight is illuminated, and a six-color field is formed to display the third B-pixel group material image. In this way, a primary color pixel data of the A pixel group and the B pixel group is interleaved during the four consecutive color fields, and the light stimulus of the continuous color field is incident on the human eye, and the color system is formed by the visual system. image. The driving method of the second embodiment differs from the driving method of the first embodiment in the method of 200847095 in that the step of adding a pixel to a pixel data after writing a single primary color A pixel data is displayed before the display. Ξ素ίΓίί, first remove the B pixel image assets remaining in the previous sub-picture, and after writing the single primary color B pixel data and displaying the foregoing B bogey material 3 image|data 刖' first remove the remaining A pixel image data from the previous page. If the singer can avoid the electricity consumption of each pixel liquid crystal cell and the residual pixel liquid crystal cell, the data of the pixel liquid crystal cell is prevented from being written to the voltage, and the pixel display image data is displayed. When it is ensured that its adjacent pixels are completely dark, it can effectively reduce the contrast of the color stripes of the aforementioned pixel edges, thereby effectively reducing the color separation phenomenon. 6A is a flow chart of the steps of the third embodiment of the field sequential color display boundary driving method for reducing color separation according to the present invention, and the single color image period generated by the driving method of the sixth c FIG. 3 embodiment (4) ^ monochrome C〇l〇r frame peri〇d) Continuous color field timing diagram. = Four A, Sixth and Sixth C to illustrate the third and physical: method.
