The intensity and saturation X of the color are not good enough to meet the display requirements. SUMMARY OF THE INVENTION In view of the above, it is a primary object of the present invention to provide a compensation modulation method which can increase the luminous flux and make the saturation of the display color better. Solid color: The secondary purpose of Haoyue is to maintain the original and colorless colorlessness after increasing the luminous flux, and to improve the color shift of the derivative color. The present invention is a driving control method for a color sequential liquid crystal color display, the method comprising the steps of: providing a multicolor backlight, the multicolor backlight providing a backlight having at least color and sequential switching. A liquid crystal shutter channel is provided for the back incident and has a light shielding state and a light passing state. A control signal timing is provided, which generates a timing of the control signal by a controller, and the timing of the control signal is divided into a normal state, a semi-quasi-state and a dynamic state. In 201019305, the timing of the control signal is semi-quasi-normal and is converted to a normal state by driving. And causing the liquid crystal shutter channel to drive the liquid crystal shutter channel as any one of the light shielding state and the light passing state, so that the liquid crystal shutter channel generates a penetration curve, and the penetration curve is in a normal state, a semi-quasi-state and a dynamic state The conversion process has a conversion delay. The control signal timing can be controlled to provide an over-level signal and a half-quasi-state signal for a short period of time when the control signal timing is switched between a normal state, a semi-quasi-state and a dynamic state, by means of the over-level The driving of the signal further shortens the switching delay, so that the liquid crystal shutter channel is quickly switched. And the backlight can be controlled to have a non-lighting time between the switching colors and control the timing of the control signal to overlap the switching delay with the non-lighting time, thereby avoiding different color backlights of the multicolor backlight. The time delay is emitted to cause color mixing. Accordingly, the present invention can reduce the conversion delay time and increase the luminous flux of different colors to increase the color saturation, and can avoid the backlight of different colors during the conversion delay time, thereby avoiding the solid color display. The color mixture causes display chromatic aberration, and in the mixed color display, the correct original design derivative color can be generated to meet the user's needs. [Embodiment] The details of the present invention will now be described with reference to the following drawings: Please refer to FIG. 4, which is a device used in the method of the present invention, which comprises a multi-color backlight 10 and a liquid crystal. The shutter channel 20 and a controller 30, wherein the multi-color backlight 10 is disposed adjacent to the liquid crystal shutter channel 201019305-20, and the controller 30 is electrically connected to the liquid crystal shutter 20 and the multi-color backlight 10 . Please refer to FIG. 5 again. The multi-color backlight 10 provides a backlight U having at least two colors and sequentially switching, and the backlight n can have a non-lighting time 12 between switching colors. u may have a red light 111, a green light 112, and a blue light 113 that are sequentially switched, and the multi-color backlight 10 may have the non-lighting time 12 at the beginning of the generation of the backlight 11. φ and the liquid crystal shutter channel 20 is incident on the backlight 11 and has a light shielding state and a light passing state, the controller 30 generates a control signal timing 31, and the control signal timing 31 can be an alternating current signal, and the control The positive and negative switching time of the signal timing 31 is the same as the total time of the backlight n switching the red light 111, the green light 112 and the blue light 113, and the control signal timing 31 is divided into the normal state 31N, the semi-quasi-state 31H and the dynamics. 31D 'where the control signal timing 31 is normally semi-quasi-state 3111 and is driven to be converted to a normal state 31N and an induced dynamic 311) to drive the liquid crystal shutter channel ❹ 20 to be either the light shielding state or the light passing state, Let the liquid crystal shutter channel 20 generate a penetration curve 21, and the penetration curve 21 has a conversion delay in the normal 31N, semi-quasi-state 31H and the dynamic 31D conversion process. Please refer to the figure again. 6), the present invention controls the control signal timing 31 to provide an over-level signal 310 for a short period of time when the control signal timing 31 is switched between the normal 31N, the semi-quasi-state 31H and the dynamic 31D. B, the over-level signal 310B is a material parameter, and the control 8 201019305 •• is the time for the optical response of the liquid crystal display panel, and the semi-quasi-state signal 310A can be further provided to connect the over-level signal 3na. The conversion delay 2U is further shortened by the driving of the over-level signal 31 〇 B and the semi-quasi-level signal 31 〇 A for a short period of time. As shown in FIG. 6 , the control signal timing 31 is controlled by the level 31H. Converted to the normal state of 31N, and then converted to semi-quasi-state 3lH. The control k-time sequence 31 is converted from the semi-quasi-state 31H to the dynamic 31D, and then converted to the semi-quasi-state 31H. Therefore, the transition curve 21 of the normalization 31N, the semi-quasi-state 31H, and the transition 31 of the dynamic 31D can be effectively shortened, and the present invention further controls the generation of the controller 3〇. The control signal timing 31 causes the conversion delay 211 to overlap with the non-emission time 12 of the backlight. Accordingly, when the present invention is used to generate a solid color display (patterns: r, g, b) and a mixed color display (the pattern is marked with c, melon, and 〇, as shown in FIG. 5), the conversion delay 211 happens to correspond to the non-lighting time 12 of the backlight u. Therefore, the light is not emitted in the conversion delay 2U, and the light of other colors can be avoided. ❹ As described above, the present invention allows the timing of the control signal 31 to be constant. The semi-quasi-state 31H, and the transition time delay 211 is shortened by the over-level signal 31〇B and the semi-quasi-state signal 310A for a short period of time, so the conversion delay 211 can be greatly shortened. The brightness is increased, and the backlight 11 is modulated to form the non-lighting time 12, so that in the solid color display, the backlight 11 of other colors can be avoided, and the problem of displaying chromatic aberration is not obtained, and in the case of mixed color display, the correct color can be generated. The original design is derived from the color to meet the needs of the user. 201019305 The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the practice of the present invention. And repair The decoration is covered by the scope of the invention. ??? = [Simple description of the drawing] Figure 1.
