第1A圖顯示根據本案第一實施例的液晶顯示器100的方塊圖，第1B圖顯示根據第1A圖的像素的例示性等效電路圖。FIG. 1A shows a block diagram of a liquid crystal display 100 according to the first embodiment of the present case, and FIG. 1B shows an exemplary equivalent circuit diagram of the pixel according to FIG. 1A.
液晶顯示器100包括：複數個閘極線G1至Gm(m為正整數)、資料線D1至Dn(n為正整數)與複數個像素PX、複數個顏色切換開關SWR1、SWR2、SWG1、SWG2、SWB1、SWB2，以及模式切換開關SWMO與SWVR。The liquid crystal display 100 includes: a plurality of gate lines G1 to Gm (m is a positive integer), data lines D1 to Dn (n is a positive integer) and a plurality of pixels PX, a plurality of color switching switches SWR1, SWR2, SWG1, SWG2, SWB1, SWB2, and mode switch SWMO and SWVR.
閘極線G1至Gm用以傳輸閘極信號(有時稱為掃描信號)，而資料線D1至Dn用以傳輸資料信號。閘極線G1至Gm大體在列方向上大體平行於彼此延伸，而資料線D1至Dn大體在行方向上大體平行於彼此延伸。因此，資料線D1至Dn大體垂直於閘極線G1至Gm。資料線D1至Dn絕緣於閘極線G1至Gm。The gate lines G1 to Gm are used to transmit gate signals (sometimes referred to as scan signals), and the data lines D1 to Dn are used to transmit data signals. The gate lines G1 to Gm extend generally parallel to each other in the column direction, and the data lines D1 to Dn extend generally parallel to each other in the row direction. Therefore, the data lines D1 to Dn are substantially perpendicular to the gate lines G1 to Gm. The data lines D1 to Dn are insulated from the gate lines G1 to Gm.
資料線D1至Dn中之每一者安置於一個像素PX之一側上。每一像素PX之側面存在一對資料線，以使得每一像素PX連接至位於相對側上之兩個資料線，且該兩個資料線位於每一對相鄰像素PX之間。Each of the data lines D1 to Dn is disposed on one side of one pixel PX. A pair of data lines exists on the side of each pixel PX, so that each pixel PX is connected to two data lines on opposite sides, and the two data lines are located between each pair of adjacent pixels PX.

In this case, the data lines D1, D3 ... coupled to the sub-pixels PXa can also be referred to as first data lines, and the data lines D2, D4 ... coupled to the sub-pixels PXb can also be referred to as the first data lines.

如第1B圖所示，該些子像素PXa與PXb連接至同一閘極線Gi，但該些子像素PXa與PXb可連接至不同之相鄰資料線Dj與Dj+1。子像素PXa連接至像素PX之第一側上的資料線(如Dj)，而子像素PXb連接至與像素PX之第一側相對之第二側上的資料線(如Dj+1)。As shown in FIG. 1B, the sub-pixels PXa and PXb are connected to the same gate line Gi, but the sub-pixels PXa and PXb can be connected to different adjacent data lines Dj and Dj + 1. The sub-pixel PXa is connected to the data line (eg Dj) on the first side of the pixel PX, and the sub-pixel PXb is connected to the data line (eg Dj + 1) on the second side opposite to the first side of the pixel PX.
開關Qa與Qb的閘極連接至閘極線G1至Gm，而開關Qa與Qb的源極極則連接至資料線D1至Dn，且開關Qa與Qb的汲極連接至儲存電容CSTa與CSTb。The gates of the switches Qa and Qb are connected to the gate lines G1 to Gm, the sources of the switches Qa and Qb are connected to the data lines D1 to Dn, and the drains of the switches Qa and Qb are connected to the storage capacitors CSTa and CSTb.
儲存電容CSTa與CSTb的一端連接至開關Qa與Qb的汲極，而其另一端則接至接地端。One ends of the storage capacitors CSTa and CSTb are connected to the drains of the switches Qa and Qb, and the other ends are connected to the ground.

現將進一步描述液晶顯示器100之操作。請參照第2A圖與第2B圖。第2A圖與第2B圖分別顯示根據本案第一實施例的液晶顯示器100操作於行動裝置模式與VR模式下的操作示意圖。The operation of the liquid crystal display 100 will now be further described. Please refer to Figure 2A and Figure 2B. FIGS. 2A and 2B respectively show operation diagrams of the liquid crystal display 100 according to the first embodiment of the present invention operating in a mobile device mode and a VR mode.
行動裝置模式：Mobile device mode:
如第2A圖所示，當本案第一實施例的液晶顯示器100欲操作於行動裝置模式下時，模式切換信號SW_MO為邏輯高，使得模式切換開關SWMO為導通，而模式切換信號SW_VR為邏輯低，使得模式切換開關SWVR為關閉。As shown in FIG. 2A, when the liquid crystal display 100 of the first embodiment of the present invention intends to operate in the mobile device mode, the mode switching signal SW_MO is logic high, so that the mode switching switch SWMO is on, and the mode switching signal SW_VR is logic low , Making the mode switch SWVR off.
在時序T11時，閘極線G1為邏輯高(導通耦接至閘極線G1的開關Qa與Qb)，第一顏色切換信號SW_1為邏輯高使得顏色切換開關SWR1與SWR2為導通，但第二與第三顏色切換信號SW_2與SW_3為邏輯低使得顏色切換開關SWG1、SWG2、SWB1與SWB2為關閉，故而，在時序T11時，資料信號D(D R)可經由模式切換開關SWMO、顏色切換開關SWR1與SWR2而寫入至連接至資料線D1與D2的儲存電容CSTa與CSTb。 At the timing T11, the gate line G1 is logic high (turn on the switches Qa and Qb coupled to the gate line G1), the first color switching signal SW_1 is logic high so that the color switching switches SWR1 and SWR2 are turned on, but the second and the third color switching signal is a logic low SW_3 SW_2 and so that the color switch SWG1, SWG2, SWB1 and SWB2 is turned off, therefore, at the timing T11, the data signals D (D R) can be switched via a mode switch SWMO, color switch SWR1 and SWR2 are written to the storage capacitors CSTa and CSTb connected to the data lines D1 and D2.
相同的，於時序T12時，資料信號D(D G)可經由模式切換開關SWMO、顏色切換開關SWG1與SWG2而寫入至連接至資料線D3與D4的儲存電容CSTa與CSTb。於時序T13時，資料信號D(D B)可經由模式切換開關SWMO、顏色切換開關SWB1與SWB2而寫入至連接至資料線D5與D6的儲存電容CSTa與CSTb。時序T14-T16的操作可依此類推。 Similarly, at the timing T12, the data signal D (D G ) can be written to the storage capacitors CSTa and CSTb connected to the data lines D3 and D4 through the mode switch SWMO, the color switches SWG1 and SWG2. When the timing at T13, the data signals D (D B) via mode switch SWMO, the switch SWB1 and SWB2 color is written to the data line connected to the storage capacitor CSTa D6 D5 and CSTb. The operations of the sequence T14-T16 can be deduced by analogy.
VR模式：VR mode:
如第2B圖所示，當本案第一實施例的液晶顯示器100欲操作於VR模式下時，模式切換信號SW_MO為邏輯低，使得模式切換開關SWMO為關閉，而模式切換信號SW_VR為邏輯高，使得模式切換開關SWVR為導通。As shown in FIG. 2B, when the liquid crystal display 100 of the first embodiment of the present invention intends to operate in the VR mode, the mode switching signal SW_MO is logic low, so that the mode switching switch SWMO is off, and the mode switching signal SW_VR is logic high, The mode switch SWVR is turned on.
在時序T21時，閘極線G1為邏輯高(導通耦接至閘極線G1的開關Qa與Qb)，第一顏色切換信號SW_1為邏輯高使得顏色切換開關SWR1與SWR2為導通，但第二與第三顏色切換信號SW_2與SW_3為邏輯低使得顏色切換開關SWG1、SWG2、SWB1與SWB2為關閉，故而，在時序T21時，資料信號D(D R)可經由顏色切換開關SWR1而寫入至連接至資料線D1的儲存電容CSTa；以及共同電壓COM可經由模式切換開關SWVR、顏色切換開關SWR2而寫入至連接至資料線D2的儲存電容CSTb。 At the timing T21, the gate line G1 is logic high (conducting the switches Qa and Qb coupled to the gate line G1), the first color switching signal SW_1 is logic high so that the color switching switches SWR1 and SWR2 are turned on, but the second and the third color switching signal is a logic low SW_3 SW_2 and so that the color switch SWG1, SWG2, SWB1 and SWB2 is turned off, therefore, at the time T21 of the timing, the data signals D (D R) can be switched via the switch SWR1 color is written to the The storage capacitor CSTa connected to the data line D1; and the common voltage COM can be written to the storage capacitor CSTb connected to the data line D2 through the mode switch SWVR and the color switch SWR2.
在時序T22時，閘極線G1為邏輯高(導通耦接至閘極線G1的開關Qa與Qb)，第二顏色切換信號SW_2為邏輯高使得顏色切換開關SWG1與SWG2為導通，但第一與第三顏色切換信號SW_1與SW_3為邏輯低使得顏色切換開關SWR1、SWR2、SWB1與SWB2為關閉，故而，在時序T22時，資料信號D(D G)可經由顏色切換開關SWG1而寫入至連接至資料線D3的儲存電容CSTa；以及共同電壓COM可經由模式切換開關SWVR、顏色切換開關SWG2而寫入至連接至資料線D4的儲存電容CSTb。 At timing T22, the gate line G1 is logic high (conducting the switches Qa and Qb coupled to the gate line G1), and the second color switching signal SW_2 is logic high so that the color switching switches SWG1 and SWG2 are turned on, but the first When the third color switching signals SW_1 and SW_3 are logic low, the color switching switches SWR1, SWR2, SWB1, and SWB2 are turned off. Therefore, at timing T22, the data signal D (D G ) can be written to through the color switching switch SWG1 The storage capacitor CSTa connected to the data line D3; and the common voltage COM can be written to the storage capacitor CSTb connected to the data line D4 through the mode switch SWVR and the color switch SWG2.
在時序T23時，閘極線G1為邏輯高(導通耦接至閘極線G1的開關Qa與Qb)，第三顏色切換信號SW_3為邏輯高使得顏色切換開關SWB1與SWB2為導通，但第一與第二顏色切換信號SW_1與SW_2為邏輯低使得顏色切換開關SWR1、SWR2、SWG1與SWG2為關閉，故而，在時序T23時，資料信號D(D B)可經由顏色切換開關SWB1而寫入至連接至資料線D5的儲存電容CSTa；以及共同電壓COM可經由模式切換開關SWVR、顏色切換開關SWB2而寫入至連接至資料線D6的儲存電容CSTb。 At timing T23, the gate line G1 is logic high (conducting the switches Qa and Qb coupled to the gate line G1), and the third color switching signal SW_3 is logic high so that the color switching switches SWB1 and SWB2 are turned on, but the first When the second color switching signals SW_1 and SW_2 are logic low, the color switching switches SWR1, SWR2, SWG1, and SWG2 are turned off. Therefore, at timing T23, the data signal D (D B ) can be written to through the color switching switch SWB1.

行動裝置模式：Mobile device mode:
如第4A圖所示，當本案第二實施例的液晶顯示器300欲操作於行動裝置模式下時，模式切換信號SW_MOA為邏輯高，使得模式切換開關SWMOA為導通，而模式切換信號SW_VRA為邏輯低，使得模式切換開關SWVRA為關閉。As shown in FIG. 4A, when the liquid crystal display 300 of the second embodiment of the present invention wants to operate in the mobile device mode, the mode switching signal SW_MOA is logic high, so that the mode switching switch SWMOA is on, and the mode switching signal SW_VRA is logic low , Makes the mode switch SWVRA off.
在時序T31時，閘極線G1為邏輯高(導通耦接至閘極線G1的開關Qa與Qb)，顏色切換信號SW_1A與SW_2A為邏輯高使得顏色切換開關SWR1A與SWR2A為導通，而其餘的顏色切換開關為關閉，故而，在時序T31時，資料信號D可經由模式切換開關SWMOA、顏色切換開關SWR1A與SWR2A而寫入至連接至資料線D1與D2的儲存電容CSTa與CSTb。At the timing T31, the gate line G1 is logic high (turning on the switches Qa and Qb coupled to the gate line G1), the color switching signals SW_1A and SW_2A are logic high so that the color switching switches SWR1A and SWR2A are turned on, and the rest The color switch is off, so at time T31, the data signal D can be written to the storage capacitors CSTa and CSTb connected to the data lines D1 and D2 through the mode switch SWMOA, the color switches SWR1A and SWR2A.
相同的，於時序T32時，資料信號D可經由模式切換開關SWMOA、顏色切換開關SWG1A與SWG2A而寫入至連接至資料線D3與D4的儲存電容CSTa與CSTb。於時序T33時，資料信號D可經由模式切換開關SWMOA、顏色切換開關SWB1A與SWB2A而寫入至連接至資料線D5與D6的儲存電容CSTa與CSTb。時序T34-T36的操作可依此類推。Similarly, at timing T32, the data signal D can be written to the storage capacitors CSTa and CSTb connected to the data lines D3 and D4 via the mode switch SWMOA, the color switch SWG1A and SWG2A.

VR模式：VR mode:
如第4B圖所示，當本案第二實施例的液晶顯示器300欲操作於VR模式下時，模式切換信號SW_MOA為邏輯低，使得模式切換開關SWMOA為關閉，而模式切換信號SW_VRA為邏輯高，使得模式切換開關SWVRA為導通。As shown in FIG. 4B, when the liquid crystal display 300 of the second embodiment of the present invention wants to operate in the VR mode, the mode switching signal SW_MOA is logic low, so that the mode switching switch SWMOA is off, and the mode switching signal SW_VRA is logic high, Make the mode switch SWVRA conductive.
在時序T41時，閘極線G1為邏輯高(導通耦接至閘極線G1的開關Qa與Qb)，顏色切換信號SW_1A為邏輯高使得顏色切換開關SWR1A為導通，但其餘顏色切換開關SWR2A、SWG1A、SWG2A、SWB1A與SWB2A為關閉，故而，在時序T41時，資料信號D可經由顏色切換開關SWR1A而寫入至連接至資料線D1的儲存電容CSTa。At timing T41, the gate line G1 is logic high (conducting the switches Qa and Qb coupled to the gate line G1), and the color switching signal SW_1A is logic high so that the color switching switch SWR1A is turned on, but the remaining color switching switches SWR2A, SWG1A, SWG2A, SWB1A and SWB2A are off.

在時序T42時，閘極線G1為邏輯高(導通耦接至閘極線G1的開關Qa與Qb)，顏色切換信號SW_2A與SW_3A為邏輯高使得顏色切換開關SWR2A與SWG1A為導通，但其餘顏色切換開關SWR1A、SWG2A、SWB1A與SWB2A為關閉，故而，在時序T42時，共同電壓COM可經由模式切換開關SWVRA、顏色切換開關SWR2A而寫入至連接至資料線D2的儲存電容CSTb；以及資料信號D可經由顏色切換開關SWG1A而寫入至連接至資料線D3的儲存電容CSTa。At time T42, the gate line G1 is logic high (conducting the switches Qa and Qb coupled to the gate line G1), and the color switching signals SW_2A and SW_3A are logic high so that the color switching switches SWR2A and SWG1A are conductive, but the remaining colors The switching switches SWR1A, SWG2A, SWB1A and SWB2A are off.

在時序T43時，閘極線G1為邏輯高(導通耦接至閘極線G1的開關Qa與Qb)，顏色切換信號SW_4A與SW_5A為邏輯高使得顏色切換開關SWG2A與SWB1A為導通，但其餘顏色切換開關SWR1A、SWR2A、SWG1A與SWB2A為關閉，故而，在時序T43時，共同電壓COM可經由模式切換開關SWVRA、顏色切換開關SWG2A而寫入至連接至資料線D4的儲存電容CSTb；以及資料信號D可經由顏色切換開關SWB1A而寫入至連接至資料線D5的儲存電容CSTa。At timing T43, the gate line G1 is logic high (conducting the switches Qa and Qb coupled to the gate line G1), and the color switching signals SW_4A and SW_5A are logic high so that the color switching switches SWG2A and SWB1A are conductive, but the remaining colors The switch SWR1A, SWR2A, SWG1A and SWB2A are off, so at time T43, the common voltage COM can be written to the storage capacitor CSTb connected to the data line D4 via the mode switch SWVRA and the color switch SWG2A; and the data signal D can be written to the storage capacitor CSTa connected to the data line D5 through the color switch SWB1A.
在時序T44時，閘極線G1為邏輯高(導通耦接至閘極線G1的開關Qa與Qb)，顏色切換信號SW_6A為邏輯高使得顏色切換開關SWB2A為導通，但其餘顏色切換開關SWR1A、SWR2A、SWG1A、SWG2A與SWB1A為關閉，故而，在時序T44時，共同電壓COM可經由模式切換開關SWVRA、顏色切換開關SWB2A而寫入至連接至資料線D6的儲存電容CSTb。At the timing T44, the gate line G1 is logic high (conducting the switches Qa and Qb coupled to the gate line G1), the color switching signal SW_6A is logic high so that the color switching switch SWB2A is turned on, but the remaining color switching switches SWR1A, SWR2A, SWG1A, SWG2A and SWB1A are off. Therefore, at timing T44, the common voltage COM can be written to the storage capacitor CSTb connected to the data line D6 via the mode switch SWVRA and the color switch SWB2A.
時序T45-T48的操作可依此類推。The operation of sequence T45-T48 can be deduced by analogy.
故而，由上述可知，在本案上述第二實施例中，當處於行動裝置模式時，資料信號D可以同時寫入至被導通的同一像素中的兩個子像素，所以可以提升液晶效率；而在VR模式時，資料信號D可以寫入至被導通的同一像素中的其中一個子像素，而共同電壓則可以寫入至被導通的同一像素中的另一個子像素，因此可以提供較為穩定的共同電壓COM給儲存電容。Therefore, as can be seen from the above, in the second embodiment of the present case, when in the mobile device mode, the data signal D can be simultaneously written to two sub-pixels in the same pixel being turned on, so the liquid crystal efficiency can be improved; and In VR mode, the data signal D can be written to one sub-pixel in the same pixel that is turned on, and the common voltage can be written to another sub-pixel in the same pixel that is turned on, thus providing a more stable common The voltage COM gives the storage capacitor.
藉此，可以使得像素保有足夠的充電時間能確保畫素電極可以充電至所需的電壓，避免了習知技術所可能會遇到的充電時間減半的問題。In this way, the pixel can have sufficient charging time to ensure that the pixel electrode can be charged to the required voltage, avoiding the problem of halving the charging time that may be encountered in the conventional technology.
