Description

顯示面板 Display panel

本發明是有關於一種顯示裝置，且特別是有關於一種能夠使電路中的發光元件操作於最佳效率點，並且能夠有效地提升佈局空間的顯示面板。 The present invention relates to a display device, and more particularly to a display panel that can make the light-emitting elements in the circuit operate at the best efficiency point and can effectively increase the layout space.

在習知技術中，顯示面板中的各個子畫素(sub-pixel)或發光元件通常具有對應的驅動電路，使得每個驅動電路能夠驅動對應的子畫素或發光元件。並且，習知的顯示面板亦會透過切換多個多工器，以將對應的資料電壓寫入至所選擇的子畫素或發光元件中。 In the prior art, each sub-pixel or light-emitting element in the display panel usually has a corresponding driving circuit, so that each driving circuit can drive the corresponding sub-pixel or light-emitting element. In addition, the conventional display panel will also switch multiple multiplexers to write the corresponding data voltages into the selected sub-pixels or light-emitting elements.

然而，當顯示面板需要較高的像素密度(Pixels Per Inch，PPI)的需求時，過多的驅動電晶體以及激光控制線將會限制顯示面板的佈局空間。此外，受限於佈局空間的情況下，驅動電路中的驅動電晶體的尺寸與所產生的驅動電流的大小亦會受到限制，進而影響了流經各個子畫素或發光元件的電流大小，使得這些發光元件無法操作於最佳效率點。另外，在窄邊框的設計需求下，過多的多工器亦會影響顯示面板的佈局面積。 However, when the display panel requires higher pixel density (Pixels Per Inch, PPI), too many driving transistors and laser control lines will limit the layout space of the display panel. In addition, when the layout space is limited, the size of the drive transistor in the drive circuit and the size of the drive current generated will also be limited, which in turn affects the size of the current flowing through each sub-pixel or light-emitting element, so that These light-emitting elements cannot operate at the best efficiency point. In addition, under the design requirements of narrow bezels, too many multiplexers will also affect the layout area of the display panel.

有鑑於此，如何有效地提升顯示面板的佈局空間，並使各個子畫素或發光元件能夠操作於最佳效率點，以改善顯示品質，將是本領域相關技術人員的課題。 In view of this, how to effectively increase the layout space of the display panel and enable each sub-pixel or light-emitting element to operate at the best efficiency point to improve the display quality will be the subject of those skilled in the art.

本發明提供一種顯示面板，能夠有效地提升佈局空間，並使發光元件操作於最佳效率點。 The present invention provides a display panel, which can effectively increase the layout space and make the light-emitting element operate at the best efficiency point.

A plurality of group selection switches are respectively coupled between the driving circuit and the plurality of sub-pixel groups. The multiple sub-pixels in the multiple sub-pixel groups are sequentially lit one by one in the laser time interval.

基於上述，本發明諸實施例所述顯示面板可以依據激光控制信號的時序狀態來選擇所需發光的子畫素或發光元件，以使驅動電路逐一依序點亮子畫素群組中的子畫素或發光元件。並且，本發明的子畫素群組可以共用同一個驅動電路，以提升顯示面板的佈局空間。如此一來，在增加了顯示面板的佈局空間下，驅動電晶體的尺寸可以相對較大，進而提升流經被點亮的子畫素或發光元件的驅動電流，以使子畫素或發光元件能夠操作於最佳效率點。 Based on the above, the display panel according to the embodiments of the present invention can select the sub-pixels or light-emitting elements to emit light according to the timing state of the laser control signal, so that the driving circuit sequentially lights the sub-pixels in the sub-pixel group one by one. Pixels or light-emitting elements. Moreover, the sub-pixel groups of the present invention can share the same driving circuit to increase the layout space of the display panel. As a result, when the layout space of the display panel is increased, the size of the driving transistor can be relatively large, thereby increasing the driving current flowing through the lit sub-pixel or light-emitting element, so that the sub-pixel or light-emitting element Able to operate at the best efficiency point.

In this embodiment, one laser time interval TEM1 of the display panel 100 can be divided into multiple sub-laser time intervals and multiple initial time intervals. Among them, for the clarity of the diagram, Figure 2 only uses the initial time interval TRW1~TRW3 and the sub-laser time interval T11~T18 as examples, and the rest of the initial time interval and sub-laser time interval can refer to the initial time interval TRW1~TRW3 And the sub-laser time interval The descriptions of T11~T18 can be deduced by analogy.

詳細來說，當顯示面板100操作於初始時間區間TRW1時，初始化電路113的電晶體M4以及M3可以依序依據被致能(例如是低電壓準位)的讀取控制信號RD以及寫入控制信號WR而被導通，以將參考電壓VREF提供至驅動電晶體MP的驅動端PD(或電容器CD的第二端)。此時，資料寫入電路111的電晶體M1可依據被致能的寫入控制信號WR而被導通，以將資料電壓VDATA提供至電容器CD的第一端。 In detail, when the display panel 100 operates in the initial time interval TRW1, the transistors M4 and M3 of the initialization circuit 113 can be sequentially enabled according to the read control signal RD and the write control signal RD that are enabled (for example, a low voltage level) The signal WR is turned on to provide the reference voltage VREF to the driving terminal PD of the driving transistor MP (or the second terminal of the capacitor CD). At this time, the transistor M1 of the data writing circuit 111 can be turned on according to the enabled writing control signal WR to provide the data voltage VDATA to the first end of the capacitor CD.

對此，驅動電路110可以在初始時間區間TRW1時對驅動端PD完成初始化之動作。值得一提的是，在本實施例中，當顯示面板100於每一次的子激光時間區間中執行操作動作之前，驅動電路110皆會進行一次的初始化動作，以重置驅動端PD上的電壓且提供對應的資料電壓VDATA。其中，驅動電路110於初始時間區間TRW2、TRW3中的實施細節可參照驅動電路110於初始時間區間TRW1的相關說明來類推，故不再贅述。 In this regard, the driving circuit 110 can complete the initialization of the driving terminal PD during the initial time interval TRW1. It is worth mentioning that, in this embodiment, before the display panel 100 performs an operation in each sub-laser time interval, the driving circuit 110 will perform an initialization operation to reset the voltage on the driving terminal PD. And provide the corresponding data voltage VDATA. The implementation details of the driving circuit 110 in the initial time interval TRW2 and TRW3 can be deduced by analogy with reference to the related description of the driving circuit 110 in the initial time interval TRW1, so it will not be repeated.

接著，當顯示面板100操作於初始時間區間TRW1之後的子激光時間區間T11時，激光電路112的電晶體M2可依據被致能(例如是低電壓準位)的控制信號EMG而被導通，以將操作電壓VBP提供至電容器CD的第一端。此時，透過電容器CD的耦合效應，驅動電路110可以將驅動端PD的電壓準位拉升至EVDD-VTH+VBP-VDATA，其中VTH為驅動電晶體MP的臨界電壓(threshold voltage)。 Then, when the display panel 100 is operated in the sub-laser time interval T11 after the initial time interval TRW1, the transistor M2 of the laser circuit 112 can be turned on according to the control signal EMG that is enabled (for example, a low voltage level) to The operating voltage VBP is provided to the first terminal of the capacitor CD. At this time, through the coupling effect of the capacitor CD, the driving circuit 110 can increase the voltage level of the driving terminal PD to EVDD-VTH+VBP-VDATA, where VTH is the threshold voltage of the driving transistor MP.

進一步來說，在子激光時間區間T11中，激光控制信號EM1以及EM2可被設定為致能狀態(例如是低電壓準位)。在此情況下，群組選擇開關T1以及子畫素SP11的控制開關A11可分別依據激光控制信號EM1以及EM2而被導通，並且驅動電路110可基於電源電壓EVDD，並依據驅動端PD上的電壓以透過群組選擇開關T1以及控制開關A11的導通路徑，選擇將驅動電流ID提供至子畫素SP11，以點亮發光元件D11。其中，經點亮的發光元件的灰階亮度可以由資料電壓VDATA的電壓大小來進行調整。 Furthermore, in the sub-laser time interval T11, the laser control signals EM1 and EM2 can be set to an enabled state (for example, a low voltage level). In this case, the group selection switch T1 and the control switch A11 of the sub-pixel SP11 can be turned on according to the laser control signals EM1 and EM2, respectively, and the driving circuit 110 can be based on the power supply voltage EVDD and based on the voltage on the driving terminal PD. Through the conduction path of the group selection switch T1 and the control switch A11, the driving current ID is selected to be supplied to the sub-pixel SP11 to light up the light-emitting element D11. Wherein, the gray-scale brightness of the lit light-emitting element can be adjusted by the voltage level of the data voltage VDATA.

In addition, in the sub-laser time interval T12 after the initial time interval TRW2, the laser control signals EM1 and EM3 can be set to an enabled state (for example, a low voltage level). In this case, the group selection switch T1 and the control switch A12 of the sub-pixel SP12 can be turned on according to the laser control signals EM1 and EM3, respectively, and the driving circuit 110 can be based on the power supply voltage EVDD and based on the voltage on the driving terminal PD Through the conduction path of the group selection switch T1 and the control switch A12, the driving current ID is selected to be supplied to the sub-pixel SP12 to light up the light-emitting element D12.
