The driving method of the color sequential display 1A shown in Fig. 2 is as follows. First, after the color sequential display 1 () is activated, a specific starting procedure is performed, for example, the adjustment control refers to the pulse modulation width signal required to display each primary color corresponding to the predetermined color sequence in FIG. 1 or The drive setting "the initial value setting of the domain human light emitting diode unit (10)" is used in the second figure, and is used by the color sequential display 2 (8). 11 201135708 The brightness value is also loaded into the LED control unit 19〇 at this time. In a first impotence, the 'v dish sensor m system returns the temperature change of the backlight module uo itself to the color sequence sensing included in the sensing controller 160 in the form of the temperature sensing signal. The light-emitting diode control unit included in the sensor control (4) sub-acquisition selects the comparison table 185 according to the target brightness value and the temperature corresponding to the temperature sensing signal, so as to obtain a brightness corresponding to each group of hearings. For example, as shown in Fig. 3, it corresponds to the bright brightness Dlf of red, green, and blue, and is called 5. , ". Wait. Then, in a second stage, the optical sensor 122 returns the actual immunity value obtained by illuminating the brightness of the backlight module and the address 120 to the color response unit 18 in the form of the domain response signal, and then The light-emitting diode control unit 19 aligns the light-emitting brightness represented by the light-sensing signal with the set of standard values that the light-emitting diode control unit has just found in the first-P view, and accordingly The illumination vanishing degree when the backlight module driving unit 126 drives the backlight module 120 is controlled. Please note that the photo-sensing signal includes actual cardimetric redundancy corresponding to different primary colors, and the photo-sensing state 122 uses the day-to-area regions TR, TG, and TB corresponding to different colors as shown in FIG. Detection (ie, detecting the actual luminance of red in the time zone TR, detecting the actual luminance of the green in the time zone TG, and detecting the actual luminance of the blue in the time zone TB). It is assumed that the actual brightness systems obtained by the light sensor 122 corresponding to different primary colors for time-series detection are respectively LR, LG, LB ' corresponding to red, green and blue, and assuming that the temperature system is 21-30, then The LED control unit 190 compares the standard brightness Dlf with the actual brightness LR, compares the standard brightness DG° with the actual brightness LG, and compares the standard brightness 〇1彳〇 with the actual brightness LB to verify each actual Whether the brightness occurs below the corresponding standard brightness. When any of the actual brightness is lower than the corresponding standard brightness, it means that the aging of the light-emitting diode causes the brightness of the light-emitting diode to be degraded, and at this time, the corresponding brightening is required. For example, say, assume that the actual brightness LR is lower than the standard brightness ton. In the case where the actual brightness of the other two is not lower than the corresponding standard brightness, the light-emitting diode control unit 19 will fine-tune the actual brightness LR, LG, LB, until the actual brightness lr, lg, The LBs are each not lower than the corresponding bright brightness to achieve white balance; it is assumed that the actual brightness LR is lower than the standard brightness Dlf, and the actual brightness (3) is lower than the standard brightness beer.

As shown in FIG. 4, the main difference between the display and the display is to add an ambient light brightness calculation unit 215 to the inductive controller (10) to exclude the % ambient light from controlling the backlight module in the light emitting diode control unit 19 The brightness shift that can be caused by the actual brightness used by unit (3). Note that in Figure 4, the inductive controller (10) is replaced with the inductive controller and the timing controller is replaced with a timing controller 21 to indicate the difference from the display in Figure 2. During the operation of the above-described display device 100, it is mentioned that the light sensor 122 utilizes various knife-time detection mechanisms of primary colors to obtain a method corresponding to the actual brightness of various primary colors; and the display of FIG. 4 is not included in the figure 200+ 'In addition to the time zone TR'TG, TB 13 201135708' applied to Figure 1, the timing mechanism of the ordering knife is to ride the actual brightness n π of each primary color, also in the time zone shown in Figure 1, (4), The Δ 进行 towel performs a time-sharing mechanism for the red, 'color ▲ color's light-free SLR, SLG, and slb. As shown in the figure, in the time zone (10), fine, please, because the pulse width modulation of red, green and blue is at a high level, the backlight spare unit (9) ', not 4 out', work color, , green, blue light; in other words, in the time zone m, only the ambient light brightness of the moonlight module 120 is measured, and since the time-sharing detection mechanism is also adopted, the In the case of the case, the dynamics correspond to different primary colors to find out the effect of ambient light on the brightness. The light-sensing '122 彳贞 ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ SLR, slg, slb, and according to the brightness (= sLR) ^ LG_SLG), (LB_SLB) to do the above two in order to achieve white balance, light redundancy adjustment, in other words, the light-emitting diode control unit is carried according to the environment _ One of the adjustments of the unit 215 has adjusted the light sensing signal to adjust the brightness of the light, so that the effect of the ambient light redundancy is eliminated in the white balance achieved by the final backlight module driving unit m. . . Referring to Fig. 5, which is a schematic view of a display device 300 according to a third embodiment of the present invention. As shown in FIG. 5, the main difference between the display 3 and the display 200 shown in FIG. 4 is that the display 3 is additionally provided with an ambient light sensor 128 for directly measuring external ambient light, and the sensing is controlled. An additional brightness statistic unit 325 is added to form an inductive controller 36. In the display device of Fig. 4, the 201135708 display device 200 applies the time-sharing detection mechanism to the ambient light detected by the light sensor 122. The brightness is the backlight module 12, which is purely exposed to ambient light when the light source is illuminated. The ambient light sensor 128 used in the figure 5 is used to directly measure the ambient line measurement of the outside of the 5|300, and the timing of the ambient light sensing g 128 it is also the first. The time zones Δτκ, ATG, ΔΤΒ shown in the figure. However, in FIG. 4, the ambient light intensity measured by the light sensor 122 directly on the light source of the moonlight module 12 has been measured to the gray scale value used when the current display 2GG is displayed, and the ambient light sensor 128 _ The directly detected ambient light is not taken into consideration according to the gray scale value used under the display g 3〇〇t, so the ambient light brightness calculation unit 215 cannot directly directly measure the external environment according to the ambient light sensor 128. The brightness is a factor that excludes ambient light in the actual luminance of illumination produced by the light sensor 122. In order to make the ambient light sensing (4) 128 side to = external ambient light brightness can be used by the ambient light brightness calculating unit to exclude the ambient light in the actual light emission, the gray level value counting unit 325 is used to drive by the color sequential display. The grayscale data corresponding to the image data is received by the controller 170, so that the ambient lightness and brightness calculation unit 215 can calculate the current transmittance according to the grayscale data received by the grayscale value statistical unit Μ5, and According to the calculated penetration accuracy, the accuracy of the received ambient light is affected by the actual brightness of the domain. Please note that in FIG. 5, the non-inductive controller 260 of FIG. 4 is replaced with the inductive controller 36〇, and the timing controller is replaced with the timing controller 310 to indicate the display 2 in the FIG. The difference between the two. In the implementation of the present invention, the influence of the ambient light brightness received by the Weiguang sensor (3) on the actual brightness of the light sensor 122 can be quantified as (ambient light brightness)* (panel penetration rate)* (The grayscale value of the side of the grayscale value statistical unit 325 is *displayed
