Achromatic The maximum gain of the LCD of the filter in terms of display efficiency is to greatly improve the light utilization efficiency, which can theoretically be increased to three times that of the conventional LCD, because an average of more than two-thirds of the light energy is colored by the color light film. Wei. In addition, if the light source is properly selected, the system can be further improved. Show f. For example, LED source, because of other light sources, such as CCFL, narrower half-height and wide surface characteristics, can show a high color saturation color, can effectively expand the system color gamut (C 〇|orGamut), meaning can present richer and more diverse colors. However, the current field-sequence full-color technology, because the reaction time of liquid crystal is generally slow, in application, 严 严 严 。 。 。 目前 目前 目前 目前The sequence of full color (F丨(10) is also called 丨Color 'FSC) reaction mode, the shortcoming of this method is the backlight module (卽灿帅(四), BUJ), the light-emitting day will find |C information writers The compression, causing the backlight core, and the lighting time is too small 'so it is not easy to achieve. In addition, the grayscale to grayscale reaction time = some grayscale city will be longer, so that it can not be changed to the insult grayscale at the specified time (four) In order to solve the problem of the upper case, the present invention proposes a new driving method of the field sequential liquid crystal display device, which is not only easy to implement, but also can improve the backlight module which is redundant due to the reaction k. Luminous time 'can also improve gray scale to ^ Switching between the problems caused by the liquid crystal reaction time. In addition, compared with the current field sequential driving method, the present invention can provide a higher brightness of the f-light module, thereby reducing the L-print power consumption or reducing the number of LEDs used. SUMMARY OF THE INVENTION The main objective of the present invention is to provide a reaction structure of a field-sequential color display and a method thereof, which are used in a liquid crystal display process towel, and when each display data sequence is input, the backlight is The module has begun to illuminate the original color and start all voltages on the liquid crystal display 7F to the end of each primary color to - the specific gray level is close to the primary color display to reach the field 200915274 The architecture of the present invention includes at least one backlight The module 'lights sequentially according to the field sequential color display to illuminate different primary colors and at least one control 1C, and is responsible for controlling the input time of the display data sequence to enable the backlight module to illuminate the primary color when the display data sequence is input, and Before the end of the primary color display, 'start a voltage to drive all the pixels on the liquid crystal display to a specific gray level until the primary color display ends. The primary colors displayed include at least red, green, and blue, and are rotated in turn, and the data is written in the same amount of time as the specific grayscale is used. In addition, through this method, the backlight module can omit the liquid crystal reaction time during the display process. The purpose, technical contents, features, and effects achieved by the present invention will become more apparent from the detailed description of the embodiments and the accompanying drawings. [Embodiment] The present invention relates to a field-sequence color display reaction and method thereof, and more particularly to a process film comprising a plurality of health elements and a backlight module, and the backlight module comprises at least: a second And - a third primary color light source, and in the first primary color sub-frame "hold 35 points free of scale - primary color light source" to transfer the plurality of data to the plurality of elements; before the end of the first primary color _ end, drive _ The first pixel is opened to the specific gray scale in the primary color sub-frame and the third primary color sub-frame respectively to open the second primary color light /=_primary light source' and the above steps are repeated to drive the liquid crystal display device. In other words, the second display shows that the f-series sequence is input at the same time, the backlight module simultaneously illuminates and illuminates the primary color, and the mother-primary color ends up reading ''! _ recording all the pixels on the display device to a specific gray as the main reaction method In the figure 2, for each - from the initial - a voltage to shout, the cold day 351 (9) of her to the liquid day display panel. Straw liquid crystal can be started by =3; ::= all the elements on f to a specific gray level 6 let the center of the heart start. Since the display time of each display data sequence 4 is 200915274, the same is true. When the nth display data sequence 4 is input, the backlight module has already illuminated and illuminates the primary color, and the display data sequence is effectively displayed in the second frame 2 The time is input from the display sequence 4 to the start of the specific grayscale 6 input, that is, t〇 to '"丨/ in the figure. When the time of displaying the data sequence 4 input and the start of the specific gray scale input are When the same, the effective display time of all the displayed data is the same. This method can make the backlight module omitting the liquid crystal reaction time during the illumination process (LC Response Tjme^ using the liquid crystal illumination brightness reflected by the present invention can be seen from Fig. 3 It is indicated that the light intensity is the square light of the human eye, and the light intensity of the shame is the integrated intensity of the light input from the display data to the initial input. Different light input will have different light integral intensity. The gray scales can be defined. By this reaction method, the effective illumination time of the backlight loose group can be improved to increase the brightness, thereby reducing the LED power consumption or reducing The number of LEDs used, and it is not limited by the liquid crystal reaction time and display data input time. In addition, the frame data can be increased by using the display data and the initial overlay write method. In the above method, the response architecture of the field sequential color display of the present invention requires at least one light module to sequentially illuminate different primary colors according to the field sequential color display signal, and the control 1C is responsible for controlling the input time of the display data sequence and the specific time. The display of gray scales is between day and day. As shown in Fig. 4, if the display data input does not overlap with the initial specific gray scale input, only one control unit C can be used to control the display data and the initial δ number. However, if the display data input overlaps with the initial specific grayscale input in time as shown in Fig. 5, the display data signal and the initial specific grayscale signal require two control ports to separately control. The present invention can be used simultaneously. In different sub-frames, according to each display line of the backlight module, different operations can be performed at the same time. If the invention is applied to liquid crystal display The display device has a field sequential color display reaction function, and only needs to match the field sequential color display reaction device of the present invention with a liquid crystal display panel, and the liquid crystal display panel has a different pixel structure than the conventional liquid crystal display panel. The sixth figure is a pixel structure diagram of the liquid crystal display panel of the present invention. When the display data input overlaps with the initial specific 200915274 gray scale input in time, as shown in FIG. 5, in order to be able to control the initial time, as shown in FIG. It is shown that each pixel structure adds an initial line and an initial scan line (丨nitia丨Scan, Si) to reflect the function of the initial specific gray level compared to the conventional technique. - A gate allows the initial line and the initial broom line to pass through the storage capacitor (Cst) and the liquid crystal capacitor (Clc). Other structures are similar to the conventional morpheme structure, including data lines and data scan lines. If the display data input does not overlap with the initial specific grayscale input in time, the pixel structure is the same as the conventional technique, and the initial voltage can be provided by the data line. Figure 7 is a diagram showing the overall structure of the present invention applied to a liquid crystal display (a, wherein each of the pixel structures in the structure is the same as the above Figure 6. Figure 8 is a liquid crystal display panel of Figure 7. The pixel structure time, for example, in a 7-inch plate containing 48 昼 昼, the reaction time of the data scan line 1 (Sd1) to the data scan line 48 〇 (Sd48〇) will sequentially jump from Sd1 to Sd480. The relative initial sweep line (Sj) will also jump from the first Si1 to Si'480, and the reaction time sequence of the initial broom line will also be in the order of the data scan line, such as the time interval between Sd1 and Si1. The same as Sd2 and Si2, and so on. The data is written at the same time as the reaction time, and the initial line is reflected from the beginning to the end. Therefore, if a liquid crystal display with field sequential color display requires at least one invention. The dedicated liquid crystal display panel is used for displaying the output screen and a sequence of color display reaction packs L in response to the display panel to have a field sequential color display. The field sequential color display reaction is as previously mentioned, including one Backlight module At least one of the above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, so that the shapes, structures, features and features described in the scope of the present application are Equivalent changes or modifications of the spirit should be included in the scope of the patent application of the present invention.
