Each of the sub-books t displays one of the two primary colors (red, green, and blue) and has an active component: each of the three primary colors can form a single pixel (Pixel^ plural scan lines 12 are electrically connected to the active component 10 The gate is used to transmit the switch nickname of the active component. The plurality of data lines 14 are electrically connected to the source of the active component 1 , and are used to transmit the data signal to the active component 1 〇. Controlling the transmittance of each sub-tenk. By changing the transmittance, the specific gravity of the three primary colors can be controlled, so that the pixels display various colors. From the color point of view, the full-color display means that each A three primary colors can be equally divided into 256 gray levels. Therefore, the depth of the tone of a liquid crystal display panel is usually described by the number of gray levels that can be displayed. For example, a 6-bit panel indicates that each of the three primary colors has 64 (= 26). Grayscale. A panel of όbits can display 262,144 (= 64x64x64) colors. An 8-bit panel indicates 256 (= 28) grayscales for each of the three primary colors. An 8-bit panel can display 16,777,216 (= 256x256x256 ) color The amount of color a panel can display is related to the cost of the system. The higher the resolution, the more colors can be displayed. However, the higher the Color Depth that the driver 1C can handle, the more the decoder will be. 1345191 On March 1st, 2011, the revised replacement page was larger and the cost was higher. In order to achieve both low cost and high color depth requirements, the use of dithering technology is usually used, and the visual persistence of the human eye is used. Add the number of colors displayed on the panel. The interpolation technique has the following two types: Spatial interpolation. This is a combination of spaces to display the intermediate tone, as shown in Figure 2, where Ln and Ln +1 represents two different tones respectively. Since spatial interpolation is a spatial operation', it is easy to produce an image on the frame and reduce the recognition rate of the image. In addition, more memory is used. Space interpolation is generally used in scalar systems. Time interpolation: This is the operation of time, which updates the color several times in an instant. Because the visual persistence 'various tones will produce a new intermediate order by the mixing of human eyes. Adjust, to achieve the effect of the interpolation method 'as shown in Figure 3. LCD display generally uses this method' also known as frame rate control technology (frame rate c〇ntr〇1 technique) 0 '^ frame rate Control technology, which increases the color depth of two bits, 1 曰 is rarely able to increase the color depth of three bits. Therefore, although frame rate control technology is a commonly used technology for panels, it can reduce costs and enhance color depth. The help provided is very limited. If the color depth of a panel is increased from 6 to 10 bits by the above two interpolation techniques, the structure of the decoder will be greatly expanded, and the operation of time will also be It has become very complicated. In order to improve the prior art, it is therefore an object of the present invention to increase the color depth with minimal complexity and to publish a hybrid frame rate control technique that enables the display to add at least a 4-bit color depth, A brief description. 6th Anniversary of March, 2001, Amendment Replacement Page [Invention] The present invention provides a hybrid frame rate control method used in a liquid crystal display, which can increase the color depth of 4 bits and can be used in color depth. On a panel of at least 4 bits. _, production costs can also be greatly reduced, and the phenomenon of flicker (Flicker) will be suppressed. It is an object of the present invention to provide a color point structure that increases the color depth of a panel. Each of the dots includes three sub-tenks (sub_d〇t). Each sub-dot includes a scan line, a data line, and a thin film transistor in which the thin film transistor is electrically connected to the scan line, the thin (four) pole valve surface, and the crystal _ Record == sub-dot electrode. The electrode size of the g-order element is 2/4, 1/4, and 1/4 of the electrode size of the corresponding dot pixel. Two sub-pixel electrodes with a quarter ratio of 1/4 are placed on the same side or both sides of the electrode of the 2/4 area. Another purpose of Comming is to provide a hybrid frame scale control method for the panels of the above architecture. After the sub-tendin is divided into three sub-sequels, a scanning signal transmitted through the scanning line will open the transistor three times at the same time in each frame. _, through the opened transistor, the first gray scale = material and the first gray scale data are divided into three sub-halogen electrodes. Finally, the third grayscale data is displayed by the sub-prime_. The third grayscale data is between the grayscale data and the second grayscale data. ^ (10) Another purpose is to provide a hybrid frame rate control method, including the number of consecutive frames that are known to constitute an image period. In the image week = inner = box 'sub-small prime (d. clever the first grayscale data and the third grayscale capital. Or 'in the image week _ frame, sub-satellite _ display the second Grayscale March 01, 2011 revised replacement; stomach data and the third grayscale data. Or 'in the image week _ frame, the dot is not the two adjacent third grayscale The difference between the object of the present invention and the conventional skill will be apparent after reading the following detailed description of the preferred embodiments. [Embodiment] The present invention provides a combination of m-domain and time-mixed frame, Method and structure. Each of the dots is divided into three sub-successes (su-dot)' and then combined with the time-interpolation technique. The sub-pixels (the ratio of the electrode area between (4), the male and the time are more Qianxin technology is heard to produce a new grayscale effect in the interpolation mode. Therefore, the present invention can change the color depth (ColorDepth) with minimal complexity. In order to realize the hybrid frame rate control method, the structure of the sub-element must be Modifications. In one embodiment, each sub element is divided into a larger secondary element and two Small and the same size of secondary sputum. And the larger electrode area of the electrode contains 2/4 of the electrode area of the corresponding sub-halogen, while the electrode area of two smaller and the same size of sputum The electrode area corresponding to the sub-halogen is 1/4.

As shown in Fig. 4(a), the two smaller ruthenium oligos 22 can be arranged in larger ones. On the left and right sides of the secondary halogen 20, or as shown in Figures 4(b) and (c), the two smaller secondary halogens 22 can be simultaneously arranged on the same side of the larger secondary pixel 2〇. The large secondary pigment 20 and the small secondary halogen 22 have different electrode area ratios, so even if the same data (ie, gray scale) is input, the brightness of the display It will also be different. By the ratio of the penetration (that is, the ratio of 'brightness') and the change of the input data to 1345191, we can get the same as the interpolation method. Gray scale.

When writing the first gray scale voltage Ln to a small sub-stimulus 22 and simultaneously entering the second gray scale voltage Ln+i to the large sub-tendin 2〇 and a small sub-昼^ l/ 4(Ln)+3/Vnf) The sub-primitives will show two gray-scale LX's. According to the above method, the sub-halogen structure of the present invention can effectively increase two without increasing the memory structure. The color depth of the bit. 6(a) to (c) show a hybrid frame rate control method of the present invention. If you need to further increase the color depth of the two bits, then after inputting the grayscale data to each of the secondary elements 20 and 22, we can use the time interpolation technique. Between displaying the current image frame and inputting the next image frame, the gray levels corresponding to the secondary pixels 2 and 22 are updated several times to achieve the effect of timely color mixing. In other words, it is said that the same gray scale can be obtained in time according to the ratio of penetration between the secondary elements, and the same effect as the interpolation method can be obtained. The gray-scale operation is no longer based on the color depth of the η-bit of the traditional sub-decibation structure, but on the color depth of the (n+2)-bit. The color frame depth of (n + 2 + 2) bits can be achieved by the hybrid frame rate control method of the present invention by the change of the sub-segment structure and the instant operation. Therefore, for a 6-bit system, we can achieve excellent image quality with a 1-bit color depth. Moreover, the 9-year-old UJ (2) repaired by the time calculation will also reduce the color depth (four) and become smaller. Of course, fuzzification can also suppress residual flashing. * Β * ί The hybrid brewing speed method determines the number of frames that make up the image. Weaving, in the several frames of the image period, the sub-denier shows no first gray level Ln and third gray level Lx. In the case of a real pay, the four consecutive messages of the weekly financial display randomly display the first gray level π in a frame of the image period and the third frame in the frame of the image period. Gray scale Lx. Another embodiment is that the sub-prima _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Another real scorpion color point randomly displays the first fire 13⁄4 Ln in the image frame _ three frames and the third gray level k in a frame of the image period. Similarly, in the embodiment of the present invention, the number of frames and = frames constituting an image period is also known. The sub-segment displays the second gray I1 white Ln+i and the third gray level .Lx in several frames of the image period. In one embodiment of the present invention, one image period has four consecutive frames and the sub-single randomly displays the second gray level Ln+1 in the frame of the image period and in the image period. The three frames show the third gray level Lx. Another embodiment is that the sub-picture reader displays the second gray level Ln two in the two frames of the image job, and displays the third gray level in the two frames of the image period, the example is The sub-study randomly displays the second grayscale 四 (four) in the three ships (four) of the image period and the third gray scale in one frame of the image period. Similarly, in the embodiment of the present invention, it is also known to constitute the connection of the image period, the health of the frame. The sub-singularity in the ® image shows that the two gradations are adjacent to the third gray level, and lx+1. In one embodiment of the present invention, one image period has four consecutive frames and the sub-pixels randomly display a third gray level in the frame of the image period and three signals in the image period. The box shows the third gray P white Lx+1 of another adjacent tone. Another embodiment is that the sub-sequence randomly corrects the replacement page 岬=苐2, the gray level LX, and the two frames in the image period to display another frame in the two frames of the image period.

Another embodiment is that the sub-study randomly displays the second order 1 in the image frame of the third frame and the third gray level Lx+ of the adjacent frame in the image frame. =. Gold = 7(a) to 7(c) respectively represent sub-two corresponding to different embodiments of the present invention; = structure. As shown in Fig. 7, each sub-pixel 24 is divided into a larger 20 And a plurality of smaller sub-halogens 22 which are equally divided into sub-halogens, wherein the electrode area ° in these embodiments, the electrode surface of the larger sub-halogen 20 = the electrode area of the sub-alcohol 24 - Half, and the smaller the element of the halogen, the electrode area is half of the electrode area of the larger ruthenium 2〇. As shown in Fig. 7(8): 'The smaller sub-pixels 22 can be arranged in the larger sub-crystals respectively. On both sides of the 2〇, or as shown in Fig. 7(b)~(c), the smaller secondary pigments can be simultaneously, and the female ^ is on the same side of the larger secondary mass 2G. According to the needs of the subsequent 24 , = 昼素 2〇 or 22 can display different gray levels. By sub-singularity π two, rate (ie: ratio of twist) and input data changes, we can iilfebAA and interpolation mode _ effect Therefore, by different colors and different deaths A, the number of colors that can be displayed by the parent child 24 can be increased, and thus the π - ^^ degree is increased. For example, the sub-tend structure shown in Figs. 7(a) to (C) It is possible to increase the color depth of the two digits. Similarly, the above-described sub-tenk structure is used in the hybrid frame rate of the present invention, and after the sub-segment is divided into several sub-successes, the n-shell to be displayed is input. And use the time interpolation technique to update the data of the secondary element between the currently displayed frame and the next image frame to be input - so that a same effect as the interpolation method can be obtained. At this time, the gray scale is calculated based on (n+2).
