Description of the Invention: [Technical Field] The present invention relates to a color shift compensation method, a driving device and a related liquid crystal display device for a liquid crystal display panel, and more particularly to a color shift compensation which can avoid color shift occurrence Method, drive device and related liquid crystal display device. [Prior Art] Liquid Crystal Display has been widely used in computer systems, mobile phones, personal digital assistants (PDAs) and other information products because of its thin appearance, low power consumption and no radiation pollution. The working principle of the liquid crystal display is to use liquid crystal molecules to have different polarization or refraction effects on light in different alignment states. Therefore, the alignment state of the liquid crystal molecules can be controlled through a thin film transistor (TFT), thereby controlling The amount of light transmitted to produce different intensity output light, and different gray intensity red, green, blue light. In liquid crystal displays, thin film transistors can be further divided into low temperature polycrystalline germanium (L〇w
Temperature Polysilicon，LTPS)與非晶矽（am〇rph〇US-siiicon)兩種 技術，詳細技術内容係業界所熟知，在此不贅述。相較於非晶石夕薄 膜電晶體液晶顯示器，低溫多晶矽薄膜電晶體液晶顯示器的反應速 度較快，且具有高亮度、高解析度、低耗電量等優點，因此，低溫 201028991 多晶矽薄膜電晶體液晶顯示器的應用範圍已越來越廣泛。 由於低溫多晶矽薄膜電晶體液晶顯示器具有較高的電子傳導速 率，液晶分子的充電時間需求較短，所以在低溫多晶矽薄膜電晶體 液晶顯示器中，一源極驅動訊號可對應到多個通道，在此情形下， 相關驅動電路中需包含有多工裝置。請參考第1圖，第1圖為習知 低溫多晶珍薄膜電晶體液晶顯示器10之部分驅動電路示竞圖。為 ❹求簡潔’第1圖僅顯示低溫多晶矽薄膜電晶體液晶顯示器1〇之畫素

不同。舉例來說，若低溫多晶矽薄膜電晶體液晶顯示器1〇為正常顯 白（Normally-white) ’若控制訊號MUX1先開啟，會因為紅色子畫 素單元R充電電壓不足而導致晝素單元PX1、ρχ2、PX3、ρχ4顯 〇示偏藍；若控制訊號MUX3先開啟，會因為藍色子晝素單元Β充電 電壓不^而讓晝素單元ΡΧ卜Ρχ2、ΡΧ3、ρχ4顯示偏紅。 因此’如何改善低溫多晶珍薄膜電晶體液晶顯示器之驅動方

Compared with amorphous Aussie thin film transistor liquid crystal display, low temperature polycrystalline germanium thin film transistor liquid crystal display has faster reaction speed, high brightness, high resolution, low power consumption, etc. Therefore, low temperature 201028991 polycrystalline germanium thin film transistor The range of applications of liquid crystal displays has become more widespread. Since the low temperature polycrystalline germanium thin film transistor liquid crystal display has a high electron conduction rate and the charging time of the liquid crystal molecules is short, in a low temperature polycrystalline germanium thin film transistor liquid crystal display, one source driving signal can correspond to a plurality of channels. In this case, a multiplexer is included in the relevant drive circuit. Please refer to FIG. 1 , which is a partial driving circuit diagram of a conventional low temperature polycrystalline thin film transistor liquid crystal display 10 . For the sake of simplicity, FIG. 1 only shows the pixel unit TM, PX2, PX3, PX4, gate drive circuit 100, source drive circuit 102, and multiplexer 104 of the low temperature polycrystalline germanium transistor transistor liquid crystal display. And a multiplex control unit 106. Each pixel unit ρχι, ΡΧ2, ΡΧ3, ρχ4 is composed of sub-pixel element scales, 〇, and 6 and is driven by different thin-film transistors to control the gray scales of red, green and blue. The gate driving circuit 1 用来 is used to output a gate driving signal GT to activate the thin film transistor of each pixel unit in time. The source driving circuit 102 is configured to output the source driving signals S1 to S4 to control the gray scale generated by each of the pixel units. The multiplexer 104 includes switching units SW1 SW SW12' for controlling the conduction of the source driving signals S1 to S4 in accordance with the control signals output from the multiplex control unit 以6 and the MUX3'. For example, when the control signal MUX1 is a pulse, the source driving signal is turned on to the pixel unit through the switching units SW1, SW4, SW7, and SW10. The red sub-alli unit R in phantom, ΡΧ2, ρχ3, ΡΧ4 charges the liquid crystal molecules (equivalent to the capacitance) to display the corresponding red gray scale. Therefore, as long as the control signals MUX Μυχ and ^^3 are sequentially output, the red, green, and blue components of each pixel can be sequentially displayed, thereby fully presenting the image content. 201028991 However, in practical applications, even if the voltage values of the source driving signals S1 to S4 are the same 'Because the low temperature polycrystalline germanium thin film transistor liquid crystal display 10 must have an unfavorable factor, the subpixel elements R, G, B are charged. The voltage may vary depending on the charging sequence. For example, if the low-temperature polycrystalline germanium thin film transistor liquid crystal display 1 is normally-white, if the control signal MUX1 is turned on first, the pixel units PX1 and ρχ2 may be caused by insufficient charging voltage of the red sub-pixel unit R. , PX3, ρχ4 display is bluish; if the control signal MUX3 is turned on first, the display unit will be reddish because the charge voltage of the blue sub-cell unit is not ^ and the pixel units ΡΧ, ΡΧ3, ρχ4 are displayed. Therefore, it is one of the goals of the industry to improve the driving mode of low-temperature polycrystalline thin film transistor liquid crystal displays to avoid color shift.

When charging a unit [Embodiment] Referring to FIG. 2, FIG. 2 is a schematic view of a liquid crystal display device 20 according to an embodiment of the present invention. The liquid positive display device 2 includes a liquid crystal display panel ((4) shirt (1) 2〇〇, an open drain driving circuit 202, a source driving circuit 2〇4, and a multiplex module 2〇6. The liquid crystal display panel 200 The best is a low temperature polycrystalline broken Temporature p〇1ysiHc〇n, LTPS) thin film electro-optical display panel, including the transfer unit of the halogen element PH] PX-mn. That is, each pixel unit can be regarded as one element of an mxn matrix, and each pixel unit is composed of sub-pixel units corresponding to red, green, and blue, that is, the same as FIG. The halogen elements ρχι, ρχ2, ρΧ3, PX4. The gate driving circuit 202, the source driving circuit 204, and the multiplex module 206 form a driving device for the liquid crystal display panel 200 for driving the liquid crystal display panel 2 to display an image. The gate driving circuit 202 is used to generate the gate driving signals GT_1 to GT_m to the pixel units PX_1_1 to PX_m_n, and the gate driving signals GT_1 to GTjn correspond to each column of the liquid crystal display panel 200. The source driving circuit 204 is configured to generate the source driving signals s_l S S_x to the multiplex module 206 to output the source driving signals S_1 S S_x to the pixel units PX_1_1 〜 px_m_n according to different starting sequences. Wherein each activation sequence corresponds to a charging timing of a sub-division unit to which all pixel units of at least one row display image content. In short, the present invention divides the pixel units ρ χ丨 χ ρ χ η into a plurality of groups, so that each group corresponds to at least one row of the liquid crystal display panel. And different groups have a non-starting order. The "starting sequence" refers to the timing of turning off (charging) the sub-pixel unit to which the pixel unit is displayed when the image is displayed, such as "red-green-blue", "blue_green-red", etc., and it not only ends in "order" The difference between "up" and "sequence" is also included. That is to say, in the display-昼面, the reference element ρχ_1_1 PX-m-η will charge the sub-pixel element in different order or timing, and the m-pixel element will have the sub-pixel of the material_color. The unit starts with the same miscellaneous. For example, if the start sequence of the group is "red-green-blue" and the start sequence of the other group is "blue-green-red", the red sub-segment unit of the former and the blue sub-picture of the latter The prime system was launched at the same time. In this case, the problem of color shift can be improved by visual homogenization. It should be noted that the "starting sequence" of the present invention refers to the charging timing of the sub-pixel unit, which can be realized by the multiplex module 2〇6, which will be described below in three embodiments. Please refer to Figures 3 to 5, and Figures 3 to 5 are schematic views of different embodiments of the multiplex module 2〇6. For the sake of brevity, some of the components of the liquid crystal display device 2 are omitted in FIGS. 3 to 5, and the complete structure can be referred to FIG. First, in the example of Fig. 3, the multiplex module 206 controls the activation sequence of the pixel units ρχ-1_1~ρχ_ι_4 by a control device CTRL_A and switching modules SW_A1 SW SW-A4. The switching modules SW_A1 to SW_A4 are composed of switching units swi~SW12, each switching unit is controlled by the control device CTRL-A for controlling signals MUX_A1, MUX_A2 and MUX_A3 outputted by the control device CTRL-A. The source driving signals S 1 201028991 ～S−4 are turned on to the corresponding sub-cell units. As can be seen from Fig. 3, the pixel unit ρχ]]~PX_1_4 is divided into two groups; the group contains the pixel unit ρχ-丨-! And, the charging order of the sub-pixel units is "red-green-blue"; the other group includes pixel units ΡΧ丄2 and ΡΧ丄4, and the charging order of the sub-unit units is "blue-green-red" "." Therefore, when the control device CTRL-Α sequentially outputs the control signal job, 匪Μ, and MUX-八3, the two groups charge the sub-cell units in different orders. For example, when the control signal MUX-A1 is a -pulse, the switching unit_, sw7 will turn on the source driving signals SJ, S-3 to the pixel unit to find the red sub-pixel unit R' of the 丨 叹 ι 3 The switching unit SW6 turns on the source driving signals S_2 and S-4 to the blue sub-pixel unit B of the pixels PX"_2 and pxj-4. With such a crane method, the same column pixel unit charges the sub-pixel elements R, G, and B in order to improve the color shift by the visual homogenization method. In the 3 ® t ’ control pack! _ CTRL__A is the simultaneous control _ read module SW_A1 ~ SW - A4 operation, in fact, the control 1CTRL-a is equivalent to four control units corresponding to the switching modules SW_A1 ~ SW_A4, and in this case, the four The control unit can be integrated to output the control signal MUX-A〗A2 and the control device CTRL_A in sequence. In addition, the two activation sequences of the pixel units PXjJ to pxj-4 are only "sequential" differences, and there is no difference in "sequence". Then, in the example of FIG. 4, the multiplex module 206 controls the pixel unit ρ χ 1 ι ρ ρ χ 1 4 by a control device ctrl_B and the switching modules SW_B1 to SW_B4'. -— Startup sequence. The switching modules SW_B1 to SWJ34 are composed of switching units SW1 SWSW12 201028991, and are used to conduct the source driving signals SJ and s_2 to the corresponding sub-salmon according to the control signal bribes ~MUX-B6 outputted by the control device CTRL_B. unit. It can be seen from the figure: the pixel unit ρ χ丄 丄 丄 对应 corresponds to four groups. Among them, the charging order of the sub-units of 7CPX丄1 and 丄2 is the same as “red-gold when going” _ 仁 在 在 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后 落后Similarly, the charging order of the sub-pixel elements of the 7C ΡΧ丄3 and ρΧ丄4 is "blue-green-red", but in the timing, the pixel unit ΡΧ丄4 falls ΡΧ丄3. Therefore, when the control device CTRL__B sequentially outputs the control signal ancestors - _^ Β 6, the pixel units ΡΧ丄1 to PXj-4 charge the sub-pixel units in different orders and timings. For example, when '(四)峨眶-B1 is a bribe, the field unit is torn, and SW12 will turn on the source drive signals Sj and s_2 to the pixel unit to find the $ dice pixel unit R and the pixel unit ρχ. The blue sub-pixel element B of 丄4. The sub-pixel elements R, G, and 会 are charged in different orders and timings by the driving method of the extended sample, and the problem of color shift is improved by the visual homogenization method. ❹ As can be seen from Fig. 4, the "starting sequence" of the present invention not only ends in the "sequential" difference, but also includes the "sequential" difference. That is, the pixel unit and the -1-2 sub-pixels have the same charging order as "red->green_>blue", but in time series, the pixel unit ΡΧ-1-2 lags behind the pixels. Unit PX-1J. Further, as in the case of Fig. 3, the control unit CTRL-B is equivalently equivalent to four control units corresponding to the switching modules sw_Bi to SW_B4. Finally, in the example of Fig. 5, the multiplex module 206 controls the starting sequence of the pixel units PXJJ to PXJ_6 by a control device CTRL c 11 201028991 and switching modules SW_C1 to SW-C6. SW_C1~SW_C6 is composed of read-only sw^swl8 'used to control the source signal Wei Jα ~MUX-C9 ' according to the control device CTRL-C output source to drive the SJ, s-2 to the Langzi pixel unit . As can be seen from Fig. 1, the pixel unit ―6 corresponds to six groups. Among them, the charging order of the sub-units of the direct element ΡΧ-1-1~ΡΧ1_3 is the same as "red-green-blue", but in the timing, the singular single SPX丄3 lags behind pxj-2, the pixel Unit 10PX-1 is behind PX-1. Similarly, the charging order of the sub-pixel elements of the pixel unit ρχ丄4~ find-u is the same as “blue-green-red”, and the sequenced sound ΡΧ丄6 lags behind the ΡΧ丄5' pixel element PXj-5. Px—j =, when the control device outputs the control signals ^^^~^^(7) in sequence, the pixel units PX丄1 to PX丄6 are charged in different order and timing by the slave unit. For example, when the control ship number 眶-C1 is a -pulse, the machine unit says that SW18 will respectively turn the source drive signals SJ, s-2 into the pixel element χ χ ^ 的 色 色 色 色 及 及 及 及The blue sub-pixel element 素- of the prime unit ρχ丄6. By the k-like driving method, the same-column pixel unit charges the sub-picture elements R, G, and B according to the order and timing, and further improves the color shift by visually equalizing. As can be seen from Fig. 5, the "starting sequence" of the pixel units pxjj to px6 is different from the charging sequence and timing. Further, as in the example of Fig. 3, the control device CTRL_C is equivalent to six control elements corresponding to the switching modules sw_ci~sw-a. ~ 12 201028991 Therefore, as can be seen from the above, in displaying a picture, the present invention charges the sub-pixel elements to which the different pixel elements belong to the same column in different orders or timings. Therefore, the sub-pixel unit of the same-column has a sub-pixel unit corresponding to the paste color activated at the same time, so that the problem of color shift can be improved by visual homogenization. The step-by-step operation can be performed on the liquid crystal panel 2 as the color shift compensation process 60, as shown in Fig. 6. The color shift compensation process 6〇 includes the following steps: Step 600: Start. Step 602: The pixel units ρ χ 丨 丨 χ χ χ n n 液晶 液晶 液晶 液晶 n n n n n n n n n n n n n n n n n n n n n n n n n n n n Step 604: According to a plurality of startup sequences, the pixel unit driving the plurality of groups is activated in a sequence corresponding to the charging timing of the sub-pixel units to which the image elements belong to all the pixel units of the group. Step 606: End. For a detailed description of the color shift compensation process 60, reference may be made to the foregoing, and will not be described herein. In the prior art, since the low temperature polycrystalline germanium thin film transistor liquid crystal display has an unfavorable factor, the voltage corresponding to the sub-cell units of different colors may be different depending on the charging order, thereby causing color shift. In the present invention, the sub-dimorph units belonging to the same-column unit are called in the same order or in sequence, and can be visually homogenized to avoid the occurrence of color shift. 13 201028991 The present invention is described in a different order or sequence, in which the sub-pixel elements to which the element belongs are charged and occur. The same is true for the different columns of the same column to avoid color shift. The above is only a preferred embodiment of the present invention, and the equal variation and modification of the patent application according to the present invention. All should fall within the scope of the present invention.
