The operation and configuration of the light-emitting elements L22, L24, the switches T21' to T27', and the capacitor C21' are similar to those of the light-emitting elements L21, L23, the switches T21 to T27, and the capacitor C21.

在不同的實施例中，發光元件L21~L24可以是微發光二極體(mLED)或其他不同類型的發光元件。在不同的實施例中，開關T21~T27、T21’~T27’可以是P型金屬氧化物半導體場效電晶體(PMOS)、N型金屬氧化物半導體場效電晶體(NMOS)、薄膜電晶體(TFT)或其他不同類型的開關元件。In different embodiments, the light emitting elements L21 to L24 may be micro light emitting diodes (mLED) or other different types of light emitting elements. In different embodiments, the switches T21~T27, T21'~T27' can be P-type metal oxide semiconductor field effect transistors (PMOS), N-type metal oxide semiconductor field effect transistors (NMOS), thin film transistors (TFT) or other different types of switching elements.

第3圖為根據本案之一實施例中的顯示裝置進行操作所繪示之時序圖。第3圖所繪示之時序圖依序包括階段P31~P36。在一些實施例中，第3圖所繪示之時序圖對應第2圖所示之不同信號，例如重置信號RST、掃描信號S(n)及S(n-1)、資料信號DT1以及控制信號VC的操作。FIG. 3 is a timing diagram drawn according to the operation of the display device in an embodiment of the present invention. The timing diagram shown in Figure 3 includes stages P31~P36 in sequence. In some embodiments, the timing diagram shown in Figure 3 corresponds to the different signals shown in Figure 2, such as reset signal RST, scan signals S(n) and S(n-1), data signal DT1, and control Operation of signal VC.

如第3圖所示，在階段P31，重置信號RST具有致能電壓準位VGH，使得開關T23導通。此時開關T23提供具有電壓準位DD的電壓信號VDD至節點N21，使得節點N21的節點電壓V21具有電壓準位DD。As shown in FIG. 3, in phase P31, the reset signal RST has the enable voltage level VGH, so that the switch T23 is turned on. At this time, the switch T23 provides the voltage signal VDD with the voltage level DD to the node N21, so that the node voltage V21 of the node N21 has the voltage level DD.

在一些實施例中，電壓準位DD為致能電壓準位，使得開關T22依據具有電壓準位DD的節點電壓V21導通。在一些實施例中，電容C21用以儲存節點N21的電荷以在開關T23關閉後維持節點電壓V21，使得開關T22在開關T23關閉後(例如在階段P32~P36)持續導通。In some embodiments, the voltage level DD is the enable voltage level, so that the switch T22 is turned on according to the node voltage V21 having the voltage level DD. In some embodiments, the capacitor C21 is used to store the charge of the node N21 to maintain the node voltage V21 after the switch T23 is turned off, so that the switch T22 is continuously turned on after the switch T23 is turned off (for example, in the phases P32 to P36).

在一些實施例中，在期間P31，資料寫入單元211的節點電壓V21被電壓信號VDD重置，使得資料寫入單元211可以準備接收資料信號DT1，因此階段P31被稱為重置階段。In some embodiments, during the period P31, the node voltage V21 of the data writing unit 211 is reset by the voltage signal VDD, so that the data writing unit 211 can prepare to receive the data signal DT1, so the stage P31 is called the reset stage.

在階段P32，控制信號VC具有致能電壓準位VGH，使得開關T21導通。電容C21在階段P31儲存之電荷使得節點電壓V21在階段P32時仍然具有致能電壓準位，因此開關T22在階段P32時導通。此時開關T22用以接收具有電壓準位SS的電壓信號VSS於節點N24。電流從節點N21通過開關T21及開關T22流向節點N24，使得節點電壓V21被拉至開關T22的臨界電壓準位V TH。此時電容C21用以接收具有電壓準位VDT31的資料信號DT1於節點N25。電容C21兩端的電壓準位差為(VDT31-V TH)。 In phase P32, the control signal VC has the enable voltage level VGH, so that the switch T21 is turned on. The charge stored in the capacitor C21 in the phase P31 makes the node voltage V21 still have the enable voltage level in the phase P32, so the switch T22 is turned on during the phase P32. At this time, the switch T22 is used to receive the voltage signal VSS with the voltage level SS at the node N24. The current flows from the node N21 to the node N24 through the switch T21 and the switch T22, so that the node voltage V21 is pulled to the threshold voltage level V TH of the switch T22. At this time, the capacitor C21 is used to receive the data signal DT1 with the voltage level VDT31 at the node N25. The voltage level difference across the capacitor C21 is (VDT31-V TH ).

在一些實施例中，在階段P32，藉由節點N21通過開關T22流向節點N24的電流，節點電壓V21的電壓準位被調整至V TH以準備補償資料寫入階段(例如階段P33及P35)及/或發光階段(例如階段P34及P36)時開關T22的臨界電壓準位V TH。因此階段P32被稱為補償階段。 In some embodiments, in the stage P32, the voltage level of the node voltage V21 is adjusted to V TH by the current flowing from the node N21 to the node N24 through the switch T22 to prepare for the compensation data writing stage (such as stages P33 and P35) and /Or the threshold voltage level V TH of the switch T22 during the light-emitting phase (such as phases P34 and P36). Therefore phase P32 is called the compensation phase.

在階段P33，資料信號DT1的電壓準位被拉至電壓準位VDT32。電容C21用以接收具有電壓準位VDT32的資料信號DT1於節點N25。此時電容C21兩端的電壓準位差為(VDT31-V TH)。對應的，節點N21的電壓準位為(VDT32-(VDT31-V TH))，即(V TH+(VDT32-VDT31))。在一些實施例中，電壓準位VDT31為零電壓準位，節點N21具有電壓準位(V TH+VDT32)。 In phase P33, the voltage level of the data signal DT1 is pulled to the voltage level VDT32. The capacitor C21 is used to receive the data signal DT1 with the voltage level VDT32 at the node N25. At this time, the voltage level difference across the capacitor C21 is (VDT31-V TH ). Correspondingly, the voltage level of the node N21 is (VDT32-(VDT31-V TH )), that is, (V TH + (VDT32-VDT31)). In some embodiments, the voltage level VDT31 is a zero voltage level, and the node N21 has a voltage level (V TH +VDT32).

在一些實施例中，在階段P33，電容C21將資料信號DT1的電壓準位VDT32寫入節點N21。因此階段P33被稱為資料寫入階段。在一些實施例中，在階段P33，資料寫入單元212依據資料信號DT2進行資料寫入操作。在一些其他的實施例中，在階段P33，周邊區域210中的其他的資料寫入單元(圖未示)依據其他的資料信號進行資料寫入操作。In some embodiments, in the phase P33, the capacitor C21 writes the voltage level VDT32 of the data signal DT1 to the node N21. Therefore, stage P33 is called the data writing stage. In some embodiments, in stage P33, the data writing unit 212 performs a data writing operation according to the data signal DT2. In some other embodiments, in stage P33, other data writing units (not shown) in the peripheral area 210 perform data writing operations based on other data signals.

在階段P34，掃描信號S(n-1)具有致能電壓準位VGH，使得開關T24導通。發光元件L21用以接收具有電壓準位DD的電壓信號VDD於節點N26。開關T22用以接收具有電壓準位SS的電壓信號VSS於節點N24。此時電流I21從節點N26依序流經發光元件L21、開關T24及T22流向節點N24，使得發光元件L21依據電流I21的電流準位發光。在一些實施例中，電流I21的電流準位決定發光元件L21的發光強度。In phase P34, the scan signal S(n-1) has the enable voltage level VGH, so that the switch T24 is turned on. The light emitting element L21 is used for receiving the voltage signal VDD with the voltage level DD at the node N26. The switch T22 is used to receive the voltage signal VSS with the voltage level SS at the node N24. At this time, the current I21 flows from the node N26 through the light emitting element L21, the switches T24 and T22 to the node N24 in order, so that the light emitting element L21 emits light according to the current level of the current I21. In some embodiments, the current level of the current I21 determines the luminous intensity of the light-emitting element L21.

在階段P34，電容C21維持了在階段P33時，節點N21的電壓準位，使得在階段P34時，節點N21具有電壓準位 (V TH+VDT32)。 In the phase P34, the capacitor C21 maintains the voltage level of the node N21 in the phase P33, so that the node N21 has the voltage level (V TH +VDT32) in the phase P34.

在一些實施例中，將開關T22的閘極與源極之電壓準位差，也就是節點N21與節點N24的電壓準位差設為電壓準位差VGS。透過電子學中的公式可得知在階段P34時通過開關T22的電流I21的電流準位為K×(VGS-V TH)^2。在階段P34，將節點N21的電壓準位(V TH+VDT32)與節點N24的電壓準位SS帶入電壓準位差VGS，即可得出電流I21的的電流準位為K×(VDT32-SS)^2，其中K為一常數。因此電流I21的電流準位與臨界電壓準位V TH無關，而與資料信號DT1的電壓準位VDT32與電壓信號VSS的電壓準位SS有關。 In some embodiments, the voltage level difference between the gate and the source of the switch T22, that is, the voltage level difference between the node N21 and the node N24, is set as the voltage level difference VGS. According to the formula in electronics, it can be known that the current level of the current I21 passing through the switch T22 at the stage P34 is K×(VGS-V TH )^2. In stage P34, the voltage level of node N21 (V TH +VDT32) and the voltage level SS of node N24 are brought into the voltage level difference VGS, and the current level of current I21 can be obtained as K×(VDT32- SS)^2, where K is a constant. Therefore, the current level of the current I21 has nothing to do with the threshold voltage level V TH , but is related to the voltage level VDT32 of the data signal DT1 and the voltage level SS of the voltage signal VSS.

在一些先前的作法中，電流通過顯示器中的不同路徑時，不同路徑上不同的電阻值會造成不同的電壓降，此外，開關的臨界電壓準位也會造成電壓降，使得流經發光元件的電流難以控制，造成顯示器的亮度不均勻的結果。In some previous practices, when current flows through different paths in the display, different resistance values on different paths will cause different voltage drops. In addition, the threshold voltage level of the switch will also cause a voltage drop, which makes the The current is difficult to control, resulting in uneven brightness of the display.

相較於上述的作法，在本發明實施例中，電壓準位VDT32與電壓準位SS係取決於使用者。如此一來，流經發光元件L21的電流可以被使用者調整，而不被電流路徑或是資料寫入單元211的元件特性，例如開關T22的臨界電壓準位V TH所影響。 Compared with the above-mentioned method, in the embodiment of the present invention, the voltage level VDT32 and the voltage level SS depend on the user. In this way, the current flowing through the light-emitting element L21 can be adjusted by the user, and is not affected by the current path or the element characteristics of the data writing unit 211, such as the threshold voltage level V TH of the switch T22.

在一些實施例中，在階段P34，發光單元221中的發光元件L21發光，因此階段P34被稱為發光階段。在一些實施例中，在階段P34，發光單元222也依據掃描信號S(n-1)進行發光操作。在一些實施例中，在階段P34，顯示區域220中的包含發光單元221及222的發光單元列中的其他發光單元(圖未示)依據掃描信號S(n-1)及其他的資料信號進行發光操作。In some embodiments, in the stage P34, the light-emitting element L21 in the light-emitting unit 221 emits light, so the stage P34 is referred to as a light-emitting stage. In some embodiments, in stage P34, the light-emitting unit 222 also performs a light-emitting operation according to the scan signal S(n-1). In some embodiments, in stage P34, other light-emitting units (not shown) in the light-emitting unit row including light-emitting units 221 and 222 in the display area 220 perform operations according to the scan signal S(n-1) and other data signals. Illumination operation.

在階段P35，資料信號DT1的電壓準位被拉至電壓準位VDT33。電容C21用以接收具有電壓準位VDT33的資料信號DT1於節點N25。此時節點N21具有電壓準位(V TH+VDT33)。 In phase P35, the voltage level of the data signal DT1 is pulled to the voltage level VDT33. The capacitor C21 is used to receive the data signal DT1 with the voltage level VDT33 at the node N25. At this time, the node N21 has a voltage level (V TH +VDT33).

在一些實施例中，在階段P35，電容C21將資料信號DT1的電壓準位VDT33寫入節點N21。因此階段P35被稱為資料寫入階段。在一些實施例中，在階段P35，資料寫入單元212依據資料信號DT2進行資料寫入操作。在一些實施例中，在階段P35，周邊區域210中的其他的資料寫入單元(圖未示)依據其他的資料信號進行資料寫入操作。In some embodiments, in the phase P35, the capacitor C21 writes the voltage level VDT33 of the data signal DT1 to the node N21. Therefore, stage P35 is called the data writing stage. In some embodiments, in stage P35, the data writing unit 212 performs a data writing operation according to the data signal DT2. In some embodiments, in stage P35, other data writing units (not shown) in the peripheral area 210 perform data writing operations based on other data signals.

在階段P36，掃描信號S(n-1)具有禁能電壓準位VGL，使得開關T24關閉。掃描信號S(n)具有致能電壓準位VGH，使得開關T26導通。發光元件L23用以接收具有電壓準位DD的電壓信號VDD於節點N27。開關T22用以接收具有電壓準位SS的電壓信號VSS於節點N24。此時電流I22從節點N27依序流經發光元件L23、開關T26及T22流向節點N24，使得發光元件L23依據電流I22的電流準位發光。在一些實施例中，電流I22的電流準位決定發光元件L23的發光強度。In phase P36, the scan signal S(n-1) has the disable voltage level VGL, so that the switch T24 is closed. The scan signal S(n) has the enable voltage level VGH, so that the switch T26 is turned on. The light emitting element L23 is used for receiving the voltage signal VDD with the voltage level DD at the node N27. The switch T22 is used to receive the voltage signal VSS with the voltage level SS at the node N24. At this time, the current I22 flows from the node N27 through the light-emitting element L23, the switches T26 and T22 to the node N24 in sequence, so that the light-emitting element L23 emits light according to the current level of the current I22. In some embodiments, the current level of the current I22 determines the luminous intensity of the light-emitting element L23.

在階段P36，電容C21維持了在階段P35時，節點N21的電壓準位，使得在階段P36時，節點N21具有電壓準位 (V TH+VDT33)。將節點N21的電壓準位 (V TH+VDT33)帶入上述電流公式可得出電流I22的電流準位為(VDT33-SS)^2。 In the phase P36, the capacitor C21 maintains the voltage level of the node N21 in the phase P35, so that the node N21 has the voltage level (V TH +VDT33) in the phase P36. Putting the voltage level (V TH +VDT33) of the node N21 into the above current formula, the current level of the current I22 can be obtained as (VDT33-SS)^2.

在一些實施例中，在階段P36，發光單元223中的發光元件L23發光，因此階段P36被稱為發光階段。在一些實施例中，在階段P36，發光單元224也依據掃描信號S(n)進行發光操作。在一些實施例中，在階段P36，顯示區域220中的包含發光單元223及224的發光單元列(圖未示) 依據掃描信號S(n) 及其他的資料信號進行發光操作。In some embodiments, in the stage P36, the light-emitting element L23 in the light-emitting unit 223 emits light, so the stage P36 is referred to as the light-emitting stage. In some embodiments, in stage P36, the light-emitting unit 224 also performs a light-emitting operation according to the scan signal S(n). In some embodiments, in stage P36, the light-emitting unit rows (not shown) including light-emitting units 223 and 224 in the display area 220 perform light-emitting operations according to the scan signal S(n) and other data signals.

在一些其他的實施例中，在階段P36之後，更多的資料寫入操作及發光操作交替進行以將資料信號DT1的更多電壓準位寫入顯示區域220中的更多發光單元(圖未示)。In some other embodiments, after the stage P36, more data writing operations and light emitting operations are alternately performed to write more voltage levels of the data signal DT1 into more light emitting cells in the display area 220 (not shown in the figure). Show).

在一些其他的實施例中，發光單元221也可以不包含開關T25。在一些實施例中，開關T25係用於檢測操作。關於檢測操作的更多細節在以下關於第8圖及第9圖的實施例中進行論述。In some other embodiments, the light emitting unit 221 may not include the switch T25. In some embodiments, the switch T25 is used to detect operation. More details on the detection operation are discussed in the following embodiments of Figs. 8 and 9.

Please refer to FIG. 4, the display device 400 is an embodiment of the display device 110. The display device 400 includes a peripheral area 410 and a display area 420.

The peripheral area 410 includes a data writing unit 411. The light emitting units 421 and 422 and the data writing unit 411 shown in FIG. 4 are similar to the light emitting units 221 and 222 and the data writing unit 211 shown in FIG. 2. The switches T41~T47, the light-emitting elements L41, L43, and the capacitor C41 in the display device 400 correspond to the switches T21~T27, the light-emitting elements L21, L23, and the capacitor C21 in the display device 200. Therefore, the connection relationship between the elements is not repeated here. Repeat it again.

在一些實施例中，顯示裝置400與顯示裝置200之區別在於，周邊區域410更包括開關T48。開關T48的控制端耦接開關T41~T43於節點N41，開關T48的一端耦接開關T41及T42於節點N42，開關T48的另一端用以接收電壓信號VSS於節點N44。In some embodiments, the difference between the display device 400 and the display device 200 is that the peripheral area 410 further includes a switch T48.

In the light-emitting phase, such as phase P34, the light-emitting unit 421 is used to receive the current I41 flowing through the switch T42 to perform a light-emitting operation. At this time, the current I41 flows through the switch T42 and the switch T48.

在一些實施例中，電流I41同時流經開關T42以及開關T48，使得電流I41具有較高電流準位。如此一來，發光元件L41的發光強度對應提升。In some embodiments, the current I41 flows through the switch T42 and the switch T48 at the same time, so that the current I41 has a higher current level. In this way, the luminous intensity of the light-emitting element L41 is correspondingly increased.

在階段P63，資料信號DT2的電壓準位被拉至電壓準位VDT52。對應的，節點N59的電壓準位被拉至電壓準位(V TH+VDT52)。在一些實施例中，電壓準位VDT51為零電壓準位。 In phase P63, the voltage level of the data signal DT2 is pulled to the voltage level VDT52. Correspondingly, the voltage level of the node N59 is pulled to the voltage level (V TH +VDT52). In some embodiments, the voltage level VDT51 is a zero voltage level.

在階段P64，掃描信號S(n-1)具有致能電壓準位VGH，使得開關T54’導通。此時電流依序流經發光元件L52、開關T54’及T52’，使得發光元件L52依據節點N59的電壓準位(V TH+VDT52)發光。 In phase P64, the scan signal S(n-1) has the enable voltage level VGH, so that the switch T54' is turned on.

在階段P65，掃描信號S(n)具有致能電壓準位VGH，使得開關T56導通。此時電流依序流經發光元件L53、開關T56及T52，使得發光元件L53依據節點N51的電壓準位(V TH+VDT53)發光。在此同時，掃描信號S(n-1)具有致能電壓準位VGH，且資料信號DT2具有電壓準位VDT52。發光元件L52依據節點N59的電壓準位(V TH+VDT52)發光。換而言之，在階段P65，發光元件L52及L53分別依據資料信號DT2及DT1同時發光。 In phase P65, the scan signal S(n) has the enable voltage level VGH, so that the switch T56 is turned on. At this time, the current flows through the light emitting element L53, the switches T56 and T52 in sequence, so that the light emitting element L53 emits light according to the voltage level (V TH +VDT53) of the node N51. At the same time, the scan signal S(n-1) has the enable voltage level VGH, and the data signal DT2 has the voltage level VDT52. The light emitting element L52 emits light according to the voltage level (V TH +VDT52) of the node N59.

And to receive the current I7. The light emitting element L73 is used to emit light according to the current I7 when the switch T73 is turned on.

如第7圖所示，修復單元720包含開關T72、容置空間729、導線M72以及焊接點P71、P72。開關T72的控制端耦接導線M72，開關T72的一端耦接容置空間729，開關T73的另一端耦接發光單元710及720。導線M72跨越掃描線701及703。在一些實施例中，導線M72堆疊於掃描線701及703之上。焊接點P71位於導線M72與掃描線701的交點。焊接點P72位於導線M72與掃描線703的交點。As shown in FIG. 7, the repair unit 720 includes a switch T72, an accommodation space 729, a wire M72, and welding points P71 and P72. The control end of the switch T72 is coupled to the wire M72, one end of the switch T72 is coupled to the accommodating space 729, and the other end of the switch T73 is coupled to the light emitting units 710 and 720. The wire M72 crosses the scan lines 701 and 703. In some embodiments, the wire M72 is stacked on the scan lines 701 and 703. The welding point P71 is located at the intersection of the wire M72 and the scanning line 701. The welding point P72 is located at the intersection of the wire M72 and the scan line 703.

在一些實施例中，導線M72用以在發光單元710異常時，通過焊接點P71耦接掃描線701及/或用以在發光單元730異常時，通過焊接點P72耦接掃描線703。容置空間729用以在發光單元710及730的至少一者異常時容納發光元件L72，使得發光元件L72耦接開關T72。In some embodiments, the wire M72 is used to couple the scan line 701 through the soldering point P71 when the light-emitting unit 710 is abnormal and/or is used to couple the scan line 703 through the soldering point P72 when the light-emitting unit 730 is abnormal. The accommodating space 729 is used for accommodating the light-emitting element L72 when at least one of the light-emitting units 710 and 730 is abnormal, so that the light-emitting element L72 is coupled to the switch T72.

舉例來說，在開關T71及/或發光元件L71發生故障使得發光單元710異常時，透過雷射焊接或其他焊接方式將導線M72耦接掃描線701於焊接點P71，並且將發光元件L72置於容置空間729中。此時發光元件L72的一端耦接開關T72，發光元件L72的另一端用以接收電壓信號VDD。開關T72的控制端用以接收掃描信號S(n-1)，開關T72的一端用以接收電流I7，使得發光元件L72依據掃描信號S(n-1)以及電流I7進行發光操作。For example, when the switch T71 and/or the light-emitting element L71 fails to cause the light-emitting unit 710 to be abnormal, the wire M72 is coupled to the scanning line 701 at the welding point P71 by laser welding or other welding methods, and the light-emitting element L72 is placed In the 729 accommodating space. At this time, one end of the light-emitting element L72 is coupled to the switch T72, and the other end of the light-emitting element L72 is used to receive the voltage signal VDD. The control terminal of the switch T72 is used to receive the scan signal S(n-1), and one end of the switch T72 is used to receive the current I7, so that the light-emitting element L72 performs a light-emitting operation according to the scan signal S(n-1) and the current I7.

換而言之，此時開關T72以及發光元件L72的配置與開關T72以及發光元件L72的配置相同。如此一來，藉由修復單元720取代發光單元710的功能，修復了顯示區域700的異常。類似地，在發光單元730異常時，修復單元720通過焊接點P72耦接掃描線703以取代發光單元730的功能。In other words, the arrangement of the switch T72 and the light-emitting element L72 at this time is the same as the arrangement of the switch T72 and the light-emitting element L72. In this way, by replacing the function of the light-emitting unit 710 with the repair unit 720, the abnormality of the display area 700 is repaired. Similarly, when the light-emitting unit 730 is abnormal, the repair unit 720 is coupled to the scan line 703 through the soldering point P72 to replace the function of the light-emitting unit 730.

在一些實施例中，顯示區域700更包含掃描線705發光單元740以及修復單元750。掃描線705用以傳輸掃描信號S(n+1)。發光單元740用以依據電流I7進行發光操作。修復單元750用以在發光單元740異常時，取代異常的發光單元740以接收電流I7進行發光操作，使得顯示區域700能夠正常發光。In some embodiments, the display area 700 further includes a scanning line 705 light-emitting unit 740 and a repair unit 750. The scan line 705 is used to transmit the scan signal S(n+1). The light-emitting unit 740 is used to perform a light-emitting operation according to the current I7. The repair unit 750 is used to replace the abnormal light-emitting unit 740 to receive the current I7 to perform a light-emitting operation when the light-emitting unit 740 is abnormal, so that the display area 700 can normally emit light.

如第7圖所示，發光單元740包含開關T74及發光元件L74。在一些實施例中，開關T74的控制端用以接收掃描信號S(n+1) 於掃描線705，開關T74的一端耦接發光元件L74，開關T74的另一端耦接修復單元750，並用以接收電流I7。發光元件L74用以在開關T74導通時依據電流I7發光。As shown in FIG. 7, the light-emitting unit 740 includes a switch T74 and a light-emitting element L74. In some embodiments, the control end of the switch T74 is used to receive the scan signal S(n+1) on the scan line 705, one end of the switch T74 is coupled to the light-emitting element L74, and the other end of the switch T74 is coupled to the repair unit 750, and is used to Receive current I7.

如第7圖所示，修復單元750包含開關T75、容置空間759、導線M75以及焊接點P73。開關T75的控制端耦接導線M75，開關T75的一端耦接容置空間759，開關T75的另一端耦接發光單元740。導線M75跨越掃描線705。在一些實施例中，導線M75堆疊於掃描線705之上。焊接點P73位於導線M75與掃描線705的交點。As shown in FIG. 7, the repair unit 750 includes a switch T75, an accommodation space 759, a wire M75, and a welding point P73. The control end of the switch T75 is coupled to the wire M75, one end of the switch T75 is coupled to the accommodating space 759, and the other end of the switch T75 is coupled to the light-emitting unit 740. The wire M75 crosses the scan line 705. In some embodiments, the wire M75 is stacked on the scan line 705. The welding point P73 is located at the intersection of the wire M75 and the scan line 705.

在一些實施例中，導線M75用以在發光單元740異常時，通過焊接點P73耦接掃描線705。容置空間759用以在發光單元740異常時容納發光元件L75，使得發光元件L75耦接開關T75。In some embodiments, the wire M75 is used to couple the scan line 705 through the soldering point P73 when the light-emitting unit 740 is abnormal. The accommodating space 759 is used for accommodating the light-emitting element L75 when the light-emitting unit 740 is abnormal, so that the light-emitting element L75 is coupled to the switch T75.

如此一來，在發光單元740異常時，藉由修復單元750取代發光單元740進行發光操作，使得顯示區域700能夠維持正常運作。In this way, when the light-emitting unit 740 is abnormal, the repair unit 750 replaces the light-emitting unit 740 to perform a light-emitting operation, so that the display area 700 can maintain normal operation.

第8圖為根據本案之一實施例所繪示之顯示裝置800的電路圖。請參照第8圖，顯示裝置800為顯示裝置110的一種實施例。FIG. 8 is a circuit diagram of a display device 800 according to an embodiment of the present invention. Please refer to FIG. 8, the display device 800 is an embodiment of the display device 110.

如第8圖所示，顯示裝置800包括發光單元821、822以及資料寫入單元811、812。第8圖所示之發光單元821~824及資料寫入單元811、812類似於第2圖所示之發光單元221~224及資料寫入單元211、212。顯示裝置800中的開關T81~T87、T81’~T87’及電容C81、C81’各自對應顯示裝置200中的開關T21~T27、T21’~T27’及電容C21、C21’，因此元件間連接關係的重複之處於此不再贅述。As shown in FIG. 8, the display device 800 includes light emitting units 821 and 822 and data writing units 811 and 812. The light emitting units 821 to 824 and the data writing units 811 and 812 shown in FIG. 8 are similar to the light emitting units 221 to 224 and the data writing units 211 and 212 shown in FIG. 2. The switches T81~T87, T81'~T87' and the capacitors C81, C81' in the display device 800 correspond to the switches T21~T27, T21'~T27' and the capacitors C21, C21' in the display device 200, so the connection relationship between the elements The repetition is here and will not be repeated here.

在一些實施例中，顯示裝置800與顯示裝置200之區別在於，顯示裝置800更包括容置空間S81~S84。容置空間S81~S84分別耦接發光單元821~824。容置空間S81耦接開關T84於節點N83，且容置空間S83耦接開關T86於節點N88。容置空間S81及S83分別用以在檢測操作之後容納發光元件L81及L83，使得發光元件L81及L83分別耦接節點N83及N88。類似地，在一些實施例中，容置空間S82及S84用以在檢測操作之後容納發光元件。關於檢測操作的更多細節在以下關於第9圖的實施例中進行論述。In some embodiments, the difference between the display device 800 and the display device 200 is that the display device 800 further includes accommodating spaces S81 to S84. The accommodating spaces S81-S84 are respectively coupled to the light-emitting units 821-824. The accommodating space S81 is coupled to the switch T84 at the node N83, and the accommodating space S83 is coupled to the switch T86 at the node N88. The accommodating spaces S81 and S83 are respectively used for accommodating the light-emitting elements L81 and L83 after the detection operation, so that the light-emitting elements L81 and L83 are respectively coupled to the nodes N83 and N88. Similarly, in some embodiments, the accommodating spaces S82 and S84 are used to accommodate the light-emitting element after the detection operation. More details about the detection operation are discussed in the embodiment of Fig. 9 below.

第9圖為根據本發明之一實施例中的顯示裝置進行檢測操作所繪示之時序圖。第9圖所繪示之時序圖依序包括階段P91~P93。在一些實施例中，第9圖所繪示之時序圖對應第8圖所示之不同信號，例如重置信號RST、掃描信號S(n)及S(n-1)、資料信號DT1的操作。FIG. 9 is a timing diagram of a detection operation performed by the display device according to an embodiment of the present invention. The timing diagram shown in Figure 9 includes stages P91~P93 in sequence. In some embodiments, the timing diagram shown in FIG. 9 corresponds to the operation of the different signals shown in FIG. 8, such as reset signal RST, scan signals S(n) and S(n-1), and data signal DT1 .

如第9圖所示，在階段P91，重置信號RST具有致能電壓準位VGH，使得開關T83導通。此時開關T83提供具有電壓準位SS1的電壓信號VSS至節點N81，使得節點N81具有電壓準位SS。As shown in FIG. 9, in phase P91, the reset signal RST has the enable voltage level VGH, so that the switch T83 is turned on. At this time, the switch T83 provides the voltage signal VSS with the voltage level SS1 to the node N81, so that the node N81 has the voltage level SS.

在一些實施例中，電壓準位SS為禁能電壓準位，使得電容C81從節點N81通過開關T83放電。在一些實施例中，當開關T83異常時，電容C81無法通過開關T83放電，使得節點N81的電壓準位異常，進而使得通過開關T82的電流異常。在一些實施例中，藉由量測通過開關T82的電流可以檢測開關T83是否異常。In some embodiments, the voltage level SS is the disable voltage level, so that the capacitor C81 is discharged from the node N81 through the switch T83. In some embodiments, when the switch T83 is abnormal, the capacitor C81 cannot be discharged through the switch T83, so that the voltage level of the node N81 is abnormal, and the current passing through the switch T82 is abnormal. In some embodiments, whether the switch T83 is abnormal can be detected by measuring the current through the switch T82.

在階段P92，掃描信號S(n-1)具有致能電壓準位VGH，使得開關T84導通。電容C81將具有電壓準位VDT91的資料信號DT1寫入節點N81以導通開關T82。開關T85用以接收具有電壓準位SS的電壓信號VSS於節點N86。開關T82用以接收具有電壓準位DD的電壓信號VDD於節點N84。此時電流從節點N84依序流經開關T82、T84及T85流向節點N86。In phase P92, the scan signal S(n-1) has the enable voltage level VGH, so that the switch T84 is turned on. The capacitor C81 writes the data signal DT1 with the voltage level VDT91 into the node N81 to turn on the switch T82. The switch T85 is used for receiving the voltage signal VSS with the voltage level SS at the node N86. The switch T82 is used to receive the voltage signal VDD with the voltage level DD at the node N84. At this time, the current flows from the node N84 through the switches T82, T84, and T85 to the node N86 in sequence.

在一些實施例中，開關T85、T84及T82之至少一者異常將使得通過開關T85的電流異常。在一些實施例中，藉由量測通過開關T85的電流可以檢測開關T85、T84及T82之至少一者是否異常。舉例來說，在開關T85因異常而無法導通時，通過開關T85的電流的電流準位為零。In some embodiments, an abnormality of at least one of the switches T85, T84, and T82 will cause the current through the switch T85 to be abnormal. In some embodiments, whether at least one of the switches T85, T84, and T82 is abnormal can be detected by measuring the current through the switch T85. For example, when the switch T85 cannot be turned on due to an abnormality, the current level of the current passing through the switch T85 is zero.

在階段P93，掃描信號S(n)具有致能電壓準位VGH，使得開關T86導通。電容C81將具有電壓準位VDT92的資料信號DT1寫入節點N81以導通開關T82。開關T87用以接收具有電壓準位SS的電壓信號VSS於節點N87。開關T82用以接收具有電壓準位DD的電壓信號VDD於節點N84。此時電流從節點N84依序流經開關T82、T86及T87流向節點N87。In phase P93, the scan signal S(n) has the enable voltage level VGH, so that the switch T86 is turned on. The capacitor C81 writes the data signal DT1 with the voltage level VDT92 into the node N81 to turn on the switch T82. The switch T87 is used to receive the voltage signal VSS with the voltage level SS at the node N87. The switch T82 is used to receive the voltage signal VDD with the voltage level DD at the node N84. At this time, the current flows from the node N84 through the switches T82, T86, and T87 to the node N87 in sequence.

在一些實施例中，開關T87、T86及T82之至少一者異常將使得通過開關T87的電流異常。在一些實施例中，藉由量測通過開關T87的電流可以檢測開關T87、T86及T82之至少一者是否異常。In some embodiments, an abnormality of at least one of the switches T87, T86, and T82 will cause the current through the switch T87 to be abnormal. In some embodiments, whether at least one of the switches T87, T86, and T82 is abnormal can be detected by measuring the current through the switch T87.

藉由階段P91~P93所述之操作依序檢測了發光單元821及823是否異常。在一些其他的實施例中，在階段P93之後，其他的掃描信號(圖未示)被拉至致能電壓準位VGH以依序檢測顯示裝置800中的其他發光單元(圖未示)是否異常。Through the operations described in stages P91 to P93, it is sequentially detected whether the light-emitting units 821 and 823 are abnormal. In some other embodiments, after the stage P93, other scan signals (not shown) are pulled to the enable voltage level VGH to sequentially detect whether other light-emitting units (not shown) in the display device 800 are abnormal. .

在一些先前的作法中，檢測訊號被提供至顯示裝置以測試顯示裝置是否有異常時，發光元件已經耦接顯示裝置。此時顯示裝置之製造成本包含發光元件之製造成本。In some previous methods, when the detection signal is provided to the display device to test whether the display device is abnormal, the light-emitting element is already coupled to the display device. At this time, the manufacturing cost of the display device includes the manufacturing cost of the light-emitting element.

相較於上述的作法，本發明實施例提供一種可以在發光元件L81及L83耦接發光單元821及823之前進行檢測的顯示裝置800，如第8圖所示。顯示裝置800為耦接發光元件之前的顯示裝置，因此顯示裝置800的製造成本較低。Compared with the above-mentioned method, the embodiment of the present invention provides a display device 800 that can perform detection before the light-emitting elements L81 and L83 are coupled to the light-emitting units 821 and 823, as shown in FIG. 8. The display device 800 is a display device before the light-emitting element is coupled, so the manufacturing cost of the display device 800 is relatively low.

在一些實施例中，在執行第9圖所述之檢測操作之後，可以將L81及L83耦接至容置空間S81及S83，亦即將發光元件L81及L83耦接顯示裝置800，使得顯示裝置800能夠執行如第3圖所述之發光操作。In some embodiments, after the detection operation described in FIG. 9 is performed, L81 and L83 can be coupled to the accommodating spaces S81 and S83, that is, the light-emitting elements L81 and L83 are coupled to the display device 800, so that the display device 800 Able to perform the light-emitting operation as described in Figure 3.

在一些實施例中，發光單元822及824之檢測操作類似於發光單元821及823之檢測操作，故於此不再重複說明。In some embodiments, the detection operation of the light-emitting units 822 and 824 is similar to the detection operation of the light-emitting units 821 and 823, so the description will not be repeated here.

本文前述各種檢測方式係用於說明，其他各種檢測方式以及信號操作方式都在本案思及的範圍中。The various detection methods mentioned in this article are used for illustration, and other various detection methods and signal operation methods are within the scope of this case.

綜上所述，在本發明實施例中，在發光元件L21發光時，開關T22的臨界電壓準位V TH被補償，使得臨界電壓準位V TH的數值大小不影響發光元件L21的發光強度。另外，由使用者決定的資料信號DT1及電壓信號VSS使得發光元件L21的發光強度不會受到電流路徑的電阻值的影響。此外，顯示裝置800可以在耦接發光元件L81及L82之前依序對821及823進行檢測，從而降低製造成本。 In summary, in the embodiment of the present invention, when the light-emitting element L21 emits light, the threshold voltage level V TH of the switch T22 is compensated, so that the value of the threshold voltage level V TH does not affect the luminous intensity of the light-emitting element L21. In addition, the data signal DT1 and the voltage signal VSS determined by the user make the luminous intensity of the light-emitting element L21 not affected by the resistance value of the current path. In addition, the display device 800 can sequentially detect 821 and 823 before coupling the light-emitting elements L81 and L82, thereby reducing the manufacturing cost.
