在一些實施例中，畫素陣列110包含多個畫素，用以接收驅動訊號(例如示於第3~7圖中的驅動訊號S1、S2、S3、V DC)以及資料訊號(例如示於第3~7圖中的資料訊號S data)，並依據驅動訊號與資料訊號顯示對應於資料訊號的影像。 In some embodiments, the pixel array 110 includes a plurality of pixels for receiving driving signals (for example, driving signals S1, S2, S3, V DC shown in FIGS. 3 to 7) and data signals (for example, shown in The data signal S data in Figures 3 to 7), and display the image corresponding to the data signal according to the drive signal and the data signal.

在一些實施例中，驅動電路120用以傳輸驅動訊號S1、S2、S3、V DC至畫素陣列110，以驅動畫素陣列110。更確切地說，驅動電路120用以傳輸驅動訊號S1、S2、S3、V DC至畫素陣列110，以致能及/或禁能畫素陣列110的至少一畫素。在一些實施例中，驅動電路120以移位暫存器實施(shift register)。在一些實施例中，驅動電路120亦稱為閘極驅動電路。 In some embodiments, the driving circuit 120 is used to transmit driving signals S1, S2, S3, and V DC to the pixel array 110 to drive the pixel array 110. More specifically, the driving circuit 120 is used to transmit the driving signals S1, S2, S3, and V DC to the pixel array 110 so as to enable and/or disable at least one pixel of the pixel array 110. In some embodiments, the driving circuit 120 is implemented as a shift register. In some embodiments, the driving circuit 120 is also referred to as a gate driving circuit.

在一些實施例中，處理電路130用以傳輸資料訊號S data至畫素陣列110，使畫素陣列110能夠依據資料訊號S data顯示。 In some embodiments, the processing circuit 130 is used to transmit the data signal S data to the pixel array 110 so that the pixel array 110 can display according to the data signal S data.

在一些實施例中，控制電路140用以控制驅動電路120與處理電路130，使驅動電路120可依據預定的時序驅動畫素陣列110，並且使處理電路130可依預定的時序傳輸資料訊號S data使畫素陣列110亦依據預定的時序顯示。在一些實施例中，控制電路140亦稱為時序控制電路。 In some embodiments, the control circuit 140 is used to control the driving circuit 120 and the processing circuit 130, so that the driving circuit 120 can drive the pixel array 110 according to a predetermined timing, and the processing circuit 130 can transmit the data signal S data according to a predetermined timing.

上述的顯示系統100的設置僅為示意之用途。各種不同的顯示系統100均在本揭露文件的考量與範疇之內。例如，在一些實施例中，顯示系統100中的控制電路140與電源供應電路150為同一電路，亦即控制電路140用以提供供應電壓OVDD、OVSS至驅動電路120、處理電路130與畫素陣列110。又或例如，在其他些實施例中，電源供應電路150為顯示系統100外之電路。The above-mentioned setting of the display system 100 is for illustrative purposes only. Various display systems 100 are within the consideration and scope of this disclosure document. For example, in some embodiments, the control circuit 140 and the power supply circuit 150 in the display system 100 are the same circuit, that is, the control circuit 140 is used to provide the supply voltages OVDD and OVSS to the driving circuit 120, the processing circuit 130, and the pixel array. 110. Or for example, in other embodiments, the power supply circuit 150 is a circuit outside the display system 100.

參考第2圖。第2圖為根據本揭示文件之一些實施例所繪示操作於第1圖中畫素陣列110的操作示意圖。在一些實施例中，畫素陣列110於一幀F中的操作包含多個子幀(sub-frame)。例如，在第2圖中，畫素陣列110於一幀F中包含4個子幀SF1、SF2、SF3、SF4，其操作順序由子幀SF1依序至子幀SF4。Refer to Figure 2. FIG. 2 is a schematic diagram illustrating the operation of the pixel array 110 in FIG. 1 according to some embodiments of the present disclosure. In some embodiments, the operation of the pixel array 110 in a frame F includes multiple sub-frames. For example, in Figure 2, the pixel array 110 includes 4 subframes SF1, SF2, SF3, and SF4 in a frame F, and the operation sequence is from subframe SF1 to subframe SF4.

在一些實施例中，畫素陣列110分為區塊110a與區塊110b。區塊110a用以顯示，區塊110b用以不顯示。如第2圖所示，在子幀SF1~SF4中，區塊110a與區塊110b分別位於畫素陣列110中的不同位置，且在子幀SF1~SF4中的4個區塊110a總共顯示了畫素陣列110全部的範圍。換言之，畫素陣列110在一幀F中顯示的影像，分別於子幀SF1~SF4顯示該影像的4個部分於4個區塊110a。因此，在一幀F中，整個畫素陣列110均有顯示，且該影像的所有部分亦均有顯示。In some embodiments, the pixel array 110 is divided into a block 110a and a block 110b. The block 110a is used for display, and the block 110b is used for not displaying. As shown in Figure 2, in the subframes SF1~SF4, the block 110a and the block 110b are located at different positions in the pixel array 110, and the four blocks 110a in the subframes SF1~SF4 show a total of The entire range of the pixel array 110. In other words, the image displayed by the pixel array 110 in one frame F respectively displays 4 parts of the image in 4 blocks 110a in the sub-frames SF1 to SF4. Therefore, in one frame F, the entire pixel array 110 is displayed, and all parts of the image are also displayed.

在一些實施例中，驅動電路120用以致能區塊110a以顯示影像，並禁能區塊110b以不顯示影像。在一些實施例中，驅動電路120用以致能畫素陣列110中多個列(row)，並禁能其餘未致能的列。該些被致能的列對應於區塊110a，該些被禁能的列對應於區塊110b。在一些進一步的實施例中，驅動電路120用以依序(例如由子幀SF1至子幀SF4之順序)致能畫素陣列110中的列，並在一幀F中，將能畫素陣列110中的列全部致能過至少一次，相應地，驅動電路120用以依序禁能其餘未被致能的列。In some embodiments, the driving circuit 120 is used to enable the block 110a to display an image, and disable the block 110b to not display an image. In some embodiments, the driving circuit 120 is used to enable a plurality of rows in the pixel array 110 and disable the remaining columns that are not enabled. The enabled columns correspond to the block 110a, and the disabled columns correspond to the block 110b. In some further embodiments, the driving circuit 120 is used to sequentially (for example, from sub-frame SF1 to sub-frame SF4) to enable the columns in the pixel array 110, and to enable the pixel array 110 in a frame F All of the rows in the row have been enabled at least once, and accordingly, the driving circuit 120 is used to sequentially disable the remaining rows that are not enabled.

在一些其他的實施例中，驅動電路120用以致能區塊110a以顯示影像，以及電源供應電路150用以禁能區塊110b以不顯示影像。In some other embodiments, the driving circuit 120 is used to enable the block 110a to display images, and the power supply circuit 150 is used to disable the block 110b to not display images.

在一些實施例中，在子幀SF1中，畫素陣列110用以接收資料訊號S data以顯示影像的一部份於區塊110a上。相應地，在子幀SF2~SF4中，畫素陣列110用以接收資料訊號S data以顯示影像的其他部份於對應的區塊110a上。 In some embodiments, in the subframe SF1, the pixel array 110 is used to receive the data signal S data to display a part of the image on the block 110a. Correspondingly, in the sub-frames SF2 to SF4, the pixel array 110 is used to receive the data signal S data to display other parts of the image on the corresponding block 110a.

在一些實施例中，在子幀SF1~SF4中，驅動電路120用以禁能區塊110b。換言之，區塊110b因為被禁能，因此畫素陣列110在區塊110b上對資料訊號S data不做顯示操作。在一些實施例中，畫素陣列110中的區塊110b不接收資料訊號S data。在一些實施例中，禁能的區塊110b呈現黑色。 In some embodiments, in the sub-frames SF1 to SF4, the driving circuit 120 is used to disable the block 110b. In other words, because the block 110b is disabled, the pixel array 110 does not display the data signal S data on the block 110b. In some embodiments, the block 110b in the pixel array 110 does not receive the data signal S data . In some embodiments, the disabled block 110b appears black.

在一些作法中，畫素陣列中的不顯示畫面的部分沒有被禁能，該不顯示畫面的部分接收影像資料訊號，並依據接收的影像資料訊號顯示黑色。因此畫素陣列不顯示畫面的部分消耗時間及電路工作成本去執行顯示工作，以顯示黑色。In some methods, the part of the pixel array that does not display the screen is not disabled, and the part that does not display the screen receives the image data signal and displays black according to the received image data signal. Therefore, the part of the pixel array that does not display the picture consumes time and circuit work cost to perform the display work to display black.

相較於上述的作法，在本案實施例中，畫素陣列110中的區塊110b被禁能，區塊110b不執行顯示工作。因此，畫素陣列110中的區塊110b不消耗時間及電路工作成本，從而提高顯示系統100的效能。Compared with the above-mentioned method, in the embodiment of the present case, the block 110b in the pixel array 110 is disabled, and the block 110b does not perform display tasks. Therefore, the block 110b in the pixel array 110 does not consume time and circuit operation cost, thereby improving the performance of the display system 100.

舉例來說，在子幀SF1中，區塊110a包含的列數為畫素陣列110全部的列數的1/4。因為區塊110b被禁能，顯示系統100在執行畫面更新時只需要處理區塊110a的部分。相較於執行畫面更新於整個畫素陣列110上，因為顯示系統100僅執行畫面更新於區塊110a上，畫面更新率可提高4倍，從而提高顯示系統100的效能。For example, in the subframe SF1, the number of columns included in the block 110a is 1/4 of the total number of columns in the pixel array 110. Because the block 110b is disabled, the display system 100 only needs to process the part of the block 110a when performing screen update. Compared with performing the image update on the entire pixel array 110, because the display system 100 only performs the image update on the block 110a, the image update rate can be increased by 4 times, thereby improving the performance of the display system 100.

上述的列數、比例與倍數僅為示意之用途。各種不同的列數、比例與倍數均在本揭露文件的考量與範疇之內。The number of columns, ratios and multiples mentioned above are for illustrative purposes only. Various number of columns, ratios and multiples are all within the consideration and scope of this disclosure document.

參考第3圖。第3圖為根據本揭示文件之一些實施例所繪示的畫素300的示意圖。畫素300為示於第1圖中畫素陣列110中多個畫素的其中一個畫素的示意圖。在一些實施例中，畫素300可代表畫素陣列110中任何一個畫素。為了簡單起見，第3圖依據示於第1~2圖之符號解釋。如第3圖所示，畫素300包含開關單元T1、開關單元T2、開關單元T3、電容C與發光單元L。在一些實施例中，開關單元T1、開關單元T2與開關單元T3為P型電晶體。在一些實施例中，發光單元L為有機發光二極體。Refer to Figure 3. FIG. 3 is a schematic diagram of a pixel 300 drawn according to some embodiments of the present disclosure. The pixel 300 is a schematic diagram of one of the pixels in the pixel array 110 shown in FIG. 1. In some embodiments, the pixel 300 may represent any pixel in the pixel array 110. For the sake of simplicity, Figure 3 is explained based on the symbols shown in Figures 1 and 2. As shown in FIG. 3, the pixel 300 includes a switch unit T1, a switch unit T2, a switch unit T3, a capacitor C, and a light emitting unit L. In some embodiments, the switch unit T1, the switch unit T2, and the switch unit T3 are P-type transistors. In some embodiments, the light emitting unit L is an organic light emitting diode.

如第3圖所示，開關單元T1的第一端用以接收處理電路130傳輸的資料訊號S data，開關單元T1的控制端用以接收驅動電路120傳輸的驅動訊號S1，以及開關單元T1的第二端耦接電容C1的第二端與開關單元T2的控制端。電容C1的第一端與開關單元T2的第一端用以接收電源供應電路150提供的供應電壓OVDD。開關單元T2的第二端耦接開關單元T3的第一端。開關單元T3的控制端用以接收驅動電路120傳輸的驅動訊號S2，以及開關單元的第二端耦接發光單元L的陽極。發光單元L的陰極用以接收電源供應電路150提供的供應電壓OVSS。 As shown in Figure 3, the first terminal of the switch unit T1 is used to receive the data signal S data transmitted by the processing circuit 130, the control terminal of the switch unit T1 is used to receive the drive signal S1 transmitted by the drive circuit 120, and the switch unit T1 The second terminal is coupled to the second terminal of the capacitor C1 and the control terminal of the switch unit T2. The first terminal of the capacitor C1 and the first terminal of the switch unit T2 are used to receive the supply voltage OVDD provided by the power supply circuit 150. The second end of the switch unit T2 is coupled to the first end of the switch unit T3. The control terminal of the switch unit T3 is used to receive the driving signal S2 transmitted by the driving circuit 120, and the second terminal of the switch unit is coupled to the anode of the light-emitting unit L. The cathode of the light emitting unit L is used to receive the supply voltage OVSS provided by the power supply circuit 150.

上述的畫素300的配置僅為示意之用途。各種不同的畫素300的配置均在本揭示文件的考量與範疇之內。例如，在一些其他的實施例中，畫素陣列110中的畫素可為第4~5圖所示的畫素400與畫素500。其細節依據第4~5圖於後敘述。The configuration of the pixel 300 described above is for illustration purposes only. The configurations of various pixels 300 are within the consideration and scope of this disclosure. For example, in some other embodiments, the pixels in the pixel array 110 may be the pixels 400 and 500 shown in FIGS. 4 to 5. The details are described later based on Figures 4 to 5.

當畫素300位於畫素陣列110的區塊110a時，畫素300被致能。驅動電路120分別傳輸驅動訊號S1與驅動訊號S2至開關單元T1與開關單元T3的控制端，以開啟開關單元T1與開關單元T3。處理電路130傳輸資料訊號S data至開關單元T1的第一端。響應資料訊號S data，畫素300產生操作電流I DS，開關單元T3傳輸操作電流I DS至發光單元L，使發光單元L發光。換言之，發光單元L因響應資料訊號S data發光。 When the pixel 300 is located in the block 110a of the pixel array 110, the pixel 300 is enabled. The driving circuit 120 respectively transmits the driving signal S1 and the driving signal S2 to the control terminals of the switch unit T1 and the switch unit T3 to turn on the switch unit T1 and the switch unit T3. The processing circuit 130 transmits the data signal S data to the first end of the switch unit T1. In response to the data signal S data , the pixel 300 generates an operating current I DS , and the switch unit T3 transmits the operating current I DS to the light-emitting unit L, so that the light-emitting unit L emits light. In other words, the light-emitting unit L emits light in response to the data signal S data .

當畫素300位於畫素陣列110的區塊110b時，畫素300被禁能。驅動電路120傳輸驅動訊號S2至開關單元T2的控制端，以關閉開關單元T3。響應驅動訊號S2，開關單元T3關閉，並降低傳輸至發光單元L的操作電流I DS，以禁能發光單元L。在一些實施例中，驅動電路120傳輸驅動訊號S1至開關單元T1的控制端，以關閉開關單元T1。處理電路130傳輸資料訊號S data至開關單元T1的第一端，因開關單元T1關閉，畫素300不接收資料訊號S data。 When the pixel 300 is located in the block 110b of the pixel array 110, the pixel 300 is disabled. The driving circuit 120 transmits the driving signal S2 to the control terminal of the switch unit T2 to turn off the switch unit T3. In response to the driving signal S2, the switch unit T3 is turned off, and the operating current IDS transmitted to the light-emitting unit L is reduced to disable the light-emitting unit L. In some embodiments, the driving circuit 120 transmits the driving signal S1 to the control terminal of the switch unit T1 to turn off the switch unit T1. The processing circuit 130 transmits the data signal S data to the first end of the switch unit T1. Because the switch unit T1 is turned off, the pixel 300 does not receive the data signal S data .

參考第4圖。第4圖為根據本揭示文件之其他些實施例所繪示的畫素400的示意圖。畫素400為示於第1圖中畫素陣列110中多個畫素的其中一個畫素的示意圖。在一些實施例中，畫素400可代表畫素陣列110中任何一個畫素。畫素400相似於第3圖中的畫素300。為了簡單起見，第4圖依據示於第1~2圖之符號解釋，其類似之元件沿用第3圖之符號。如第4圖所示，相較於畫素300，畫素400更包含開關單元T4。Refer to Figure 4. FIG. 4 is a schematic diagram of a pixel 400 drawn according to other embodiments of the present disclosure. The pixel 400 is a schematic diagram of one of the pixels in the pixel array 110 shown in FIG. 1. In some embodiments, the pixel 400 may represent any pixel in the pixel array 110. The pixel 400 is similar to the pixel 300 in Figure 3. For the sake of simplicity, Figure 4 is explained based on the symbols shown in Figures 1 and 2, and the symbols in Figure 3 are used for similar components. As shown in FIG. 4, compared to the pixel 300, the pixel 400 further includes a switch unit T4.

當畫素400位於畫素陣列110的區塊110a時，畫素400被致能。驅動電路120分別傳輸驅動訊號S1與驅動訊號S2至開關單元T1與開關單元T3的控制端，以開啟開關單元T1與開關單元T3。驅動電路120傳輸驅動訊號S3至開關單元T4的控制端，以關閉開關單元T4。處理電路130傳輸資料訊號S data至開關單元T1的第一端。響應資料訊號S data，畫素400產生操作電流I DS，開關單元T3傳輸操作電流I DS至發光單元L，使發光單元L發光。換言之，發光單元L因響應資料訊號S data發光。 When the pixel 400 is located in the block 110a of the pixel array 110, the pixel 400 is enabled. The driving circuit 120 respectively transmits the driving signal S1 and the driving signal S2 to the control terminals of the switch unit T1 and the switch unit T3 to turn on the switch unit T1 and the switch unit T3. The driving circuit 120 transmits the driving signal S3 to the control terminal of the switch unit T4 to turn off the switch unit T4. The processing circuit 130 transmits the data signal S data to the first end of the switch unit T1. In response to the data signal S data , the pixel 400 generates an operating current I DS , and the switch unit T3 transmits the operating current I DS to the light-emitting unit L, so that the light-emitting unit L emits light. In other words, the light-emitting unit L emits light in response to the data signal S data .

當畫素400位於畫素陣列110的區塊110b時，畫素400被禁能。驅動電路120傳輸驅動訊號S3至開關單元T4的控制端，以開啟開關單元T4。響應驅動訊號S3，開關單元T4開啟，開關單元T4從而輸出操作電壓V ANO於開關單元T4的第一端，以禁能發光單元L。 When the pixel 400 is located in the block 110b of the pixel array 110, the pixel 400 is disabled. The driving circuit 120 transmits the driving signal S3 to the control terminal of the switch unit T4 to turn on the switch unit T4. In response to the driving signal S3, the switch unit T4 is turned on, and the switch unit T4 thus outputs the operating voltage V ANO to the first end of the switch unit T4 to disable the light-emitting unit L.

在一些實施例中，發光單元L具有臨界電壓Vth，當發光單元L的陽極與陰極的電壓差大於臨界電壓Vth時，發光單元L發光。承上所述，在一些實施例中，位於畫素陣列110的區塊110b的畫素400，當其發光單元L的陽極上的電壓不大於供應電壓VOSS與臨界電壓Vth的和，發光單元L不發光。亦即，當開關單元T4輸出在發光單元L的陽極上的操作電壓V ANO不大於供應電壓VOSS與臨界電壓Vth的和時，發光單元L不發光。在一些實施例中，發光單元L的臨界電壓Vth為大約0.6V。 In some embodiments, the light-emitting unit L has a threshold voltage Vth. When the voltage difference between the anode and the cathode of the light-emitting unit L is greater than the threshold voltage Vth, the light-emitting unit L emits light. As mentioned above, in some embodiments, when the voltage on the anode of the light-emitting unit L of the pixel 400 located in the block 110b of the pixel array 110 is not greater than the sum of the supply voltage VOSS and the threshold voltage Vth, the light-emitting unit L Does not emit light. That is, when the operating voltage V ANO output by the switch unit T4 on the anode of the light-emitting unit L is not greater than the sum of the supply voltage VOSS and the threshold voltage Vth, the light-emitting unit L does not emit light. In some embodiments, the threshold voltage Vth of the light-emitting unit L is about 0.6V.

在一些實施例中，驅動電路120傳輸驅動訊號S1至開關單元T1的控制端，以關閉開關單元T1。處理電路130傳輸資料訊號S data至開關單元T1的第一端，因開關單元T1關閉，畫素400不接收資料訊號S data。 In some embodiments, the driving circuit 120 transmits the driving signal S1 to the control terminal of the switch unit T1 to turn off the switch unit T1. The processing circuit 130 transmits the data signal S data to the first end of the switch unit T1. Because the switch unit T1 is turned off, the pixel 400 does not receive the data signal S data .

參考第5圖。第5圖為根據本揭示文件之一些替代地實施例所繪示的畫素500的示意圖。畫素500為示於第1圖中畫素陣列110中多個畫素的其中一個畫素的示意圖。在一些實施例中，畫素500可代表畫素陣列110中任何一個畫素。畫素500相似於第4圖中的畫素400。為了簡單起見，第5圖依據示於第1~2圖之符號解釋，其類似之元件沿用第4圖之符號。Refer to Figure 5.

The driving circuit 120 respectively transmits the driving signal S1 and the driving signal S2 to the control terminals of the switch unit T1 and the switch unit T3 to turn on the switch unit T1 and the switch unit T3. The driving circuit 120 transmits the driving signal S3 to the control terminal of the switch unit T4 to turn off the switch unit T4. The processing circuit 130 transmits the data signal S data to the first end of the switch unit T1. In response to the data signal S data , the pixel 500 generates an operating current I DS , and the switch unit T3 transmits the operating current I DS to the light-emitting unit L, so that the light-emitting unit L emits light. In other words, the light-emitting unit L emits light in response to the data signal S data .

當畫素500位於畫素陣列110的區塊110b時，畫素500被禁能。驅動電路120傳輸驅動訊號S3至開關單元T4的控制端以開啟開關單元T4，以及傳輸驅動訊號V DC至開關單元T4的第二端。響應驅動訊號S3與驅動訊號V DC，開關單元T4開啟並輸出操作電壓V ANO於開關單元T4的第一端，以禁能發光單元L。 When the pixel 500 is located in the block 110b of the pixel array 110, the pixel 500 is disabled. The driving circuit 120 transmits the driving signal S3 to the control end of the switch unit T4 to turn on the switch unit T4, and transmits the driving signal V DC to the second end of the switch unit T4. In response to the driving signal S3 and the driving signal V DC , the switch unit T4 is turned on and outputs an operating voltage V ANO to the first end of the switch unit T4 to disable the light-emitting unit L.

在一些實施例中，當位於畫素陣列110的區塊110b的畫素500，其發光單元L的陽極上的電壓不大於供應電壓VOSS與臨界電壓Vth的和，開關單元L不發光。亦即，當開關單元T4輸出在發光單元L的陽極上的操作電壓V ANO不大於供應電壓VOSS與臨界電壓Vth的和時，開關單元L不發光。 In some embodiments, when the voltage on the anode of the light-emitting unit L of the pixel 500 located in the block 110b of the pixel array 110 is not greater than the sum of the supply voltage VOSS and the threshold voltage Vth, the switch unit L does not emit light. That is, when the operating voltage V ANO output by the switch unit T4 on the anode of the light-emitting unit L is not greater than the sum of the supply voltage VOSS and the threshold voltage Vth, the switch unit L does not emit light.

在一些實施例中，驅動電路120傳輸驅動訊號S1至開關單元T1的控制端，以關閉開關單元T1。處理電路130傳輸資料訊號S data至開關單元T1的第一端，因開關單元T1關閉，畫素500不接收資料訊號S data。 In some embodiments, the driving circuit 120 transmits the driving signal S1 to the control terminal of the switch unit T1 to turn off the switch unit T1. The processing circuit 130 transmits the data signal S data to the first end of the switch unit T1. Because the switch unit T1 is turned off, the pixel 500 does not receive the data signal S data .

參考第6圖。第6圖為根據本揭示文件之一些實施例所繪示的畫素陣列610的示意圖。畫素陣列610包含多個示於第3圖的畫素300。如第6圖所示，畫素陣列610以N*2矩陣排列。在一些實施例中，畫素陣列610為示於第1圖的畫素陣列110的部分。為了簡單起見，第6圖依據示於第1~3圖之符號解釋，其類似之元件沿用第1~3圖之符號，且畫素300之敘述於此不再重複。Refer to Figure 6. FIG. 6 is a schematic diagram of a pixel array 610 according to some embodiments of the present disclosure. The pixel array 610 includes a plurality of pixels 300 shown in FIG. 3. As shown in Fig. 6, the pixel array 610 is arranged in an N*2 matrix. In some embodiments, the pixel array 610 is part of the pixel array 110 shown in FIG. 1. For the sake of simplicity, Fig. 6 is explained based on the symbols shown in Figs. 1 to 3, and its similar components follow the symbols in Figs. 1 to 3, and the description of the pixel 300 is not repeated here.

如第6圖所示，畫素陣列610包含N個列，每個列上的畫素300耦接開關裝置SWH。開關裝置SWH耦接在電源供應電路150與畫素陣列610之間。更確切地說，開關裝置SWH耦接在開關元件T2與電容C的第一端和電源供應電路150之間。在一些實施例中，開關裝置SWH用以依據電源致能控制訊號PEN1以控制供應電壓OVDD是否傳輸至對應的畫素300。As shown in FIG. 6, the pixel array 610 includes N columns, and the pixel 300 on each column is coupled to the switching device SWH. The switching device SWH is coupled between the power supply circuit 150 and the pixel array 610. More specifically, the switching device SWH is coupled between the switching element T2 and the first end of the capacitor C and the power supply circuit 150. In some embodiments, the switch device SWH is used to control whether the supply voltage OVDD is transmitted to the corresponding pixel 300 according to the power enable control signal PEN1.

在一些實施例中，當畫素陣列110的區塊110a包含畫素陣列610中的第1列至第3列時，對應至畫素陣列610中的第1列至第3列的開關裝置SWH依據電源致能控制訊號PEN1傳輸供應電壓OVDD至該畫素陣列610的第1列至第3列。畫素陣列610的第1列至第3列中的畫素300因此被致能從而使畫素300中的發光單元L響應資料訊號S data發光。 In some embodiments, when the block 110a of the pixel array 110 includes the first to third columns in the pixel array 610, it corresponds to the switching devices SWH in the first to third columns in the pixel array 610 The supply voltage OVDD is transmitted to the first row to the third row of the pixel array 610 according to the power enable control signal PEN1. The pixels 300 in the first row to the third row of the pixel array 610 are thus enabled so that the light-emitting unit L in the pixel 300 emits light in response to the data signal S data .

The switching device SWH corresponding to the fourth column to the Nth column in the pixel array 610 stops transmitting the supply voltage OVDD to the fourth column to the Nth column of the pixel array 610 according to the power enable control signal PEN1. The pixels 300 in the fourth column to the Nth column of the pixel array 610 are therefore disabled, so that the light-emitting unit L in the pixel 300 does not perform operations in response to the data signal S data. In some embodiments, the driving circuit 120 transmits the driving signal S1 to the control terminal of the switch unit T1 to turn off the switch unit T1. The processing circuit 130 transmits the data signal S data to the first end of the switch unit T1. Because the switch unit T1 is turned off, the pixels 300 in the fourth row to the N-th row in the pixel array 610 do not receive the data signal S data .
