[0041] Overview

[0042] As described in the background art, the internal wiring of display devices currently occupies a large plane space. In particular, the wiring in the frame will make the frame of the display panel larger. Figure 1 As shown, there are multiple light-emitting units 4 in area AA (display area) of the display screen, and the scanning line (Gate) wiring of area AA (display area) of the display screen is led out from the left and right frames 2 of the display screen, thereby causing the left and right frames 2 of the display screen to become larger and the display area 1 of the display screen to become smaller; in addition, the signal line (source) wiring in area AA of the display screen uses one signal line to connect the light-emitting units in a column on the same side, thereby causing the number of signal line (source) wiring to increase, and at the same time, the number of signal lines led out from the display area of ​​the display screen to the lower frame 3 increases, resulting in the lower frame of the display screen occupying a larger space and a smaller display area.

[0043] In view of the above problems, the inventors have improved the display structure, such as Figure 2 As shown, the details are as follows:

[0044] Based on GIAA (Gate in AA) technology, the scan line Gate is connected in the AA area (display area), so that the scan line Gate and the signal line source in the display area 1 are led out from the lower frame 3 of the display screen, and no longer occupy the left and right frames 2 of the display screen, thereby achieving the effect of no left and right frames of the display screen;

[0045] Based on the HSD (Half source design) technology, the two sides of a signal line source located in the display area are respectively connected to the source or drain of the switch gate tubes in the two light-emitting units 4 on both sides, thereby effectively reducing the number of wiring of the signal line source in the display area, shortening the lower frame 3 of the display screen, reducing costs, and being suitable for small-sized screens;

[0046] A mux (multiplexing) circuit is added to connect one data line data with at least two signal lines source, so that one data line data can control multiple signal lines source, thereby reducing the space of the lower frame 3 occupied by the data line data and achieving an extremely narrow lower frame effect of the display screen.

[0047] Based on the above concept, the present application will be exemplarily described below in conjunction with the accompanying drawings.

[0048] Exemplary Structure

[0049] This embodiment provides a display panel such as Figure 2 and Figure 3 As shown, the display panel includes a display area, and the display area includes a plurality of evenly arranged light-emitting units 4, each of which is composed of a 2T1C (i.e., comprising two transistors TFT and a capacitor Cst) driving circuit. The display panel also includes a plurality of signal lines source and a plurality of scan lines Gate. At least part of the signal line source is arranged in the display area and extends in the column direction. The plurality of signal lines source are parallel to each other and connected to the light-emitting units 4 arranged in the longitudinal direction, and the signal line source is led out from the bottom of the display area to the lower frame of the display screen. At least part of the scan line Gate is arranged in the display area, wherein the scan line Gate extending in the row direction and in the column direction is used to connect with the light-emitting unit 4, and the scan line Gate extending in the column direction and arranged in the row direction is parallel to the signal line source and is led out from the bottom of the display area to the lower frame of the display screen like the signal line source, so that the left and right frames of the display screen are no longer occupied, thereby achieving the effect of the display screen having no left and right frames.

[0050] Specifically, the light-emitting unit includes at least one first light-emitting unit 41 and at least one second light-emitting unit 42. The first light-emitting unit 41 and the second light-emitting unit 42 are arranged on both sides of the corresponding signal line source, that is, the first light-emitting unit 41 is located on the first side of the signal line source, and the second light-emitting unit 42 is located on the second side of the signal line source. In addition, the first connection end of the first light-emitting unit 41 is electrically connected to the signal line source from the first side of the signal line source, and the first connection end of the second light-emitting unit 42 is electrically connected to the signal line source from the second side of the signal line source. The second connection end of the first light-emitting unit 41 is electrically connected to the scan line Gate extending in the row direction and arranged in the column direction, and the second connection end of the second light-emitting unit 42 is also electrically connected to the scan line Gate extending in the row direction and arranged in the column direction.

[0051] Further, the scan line Gate includes a plurality of first scan lines G1 and a plurality of second scan lines G2. The first scan lines G1 extend in the column direction and are arranged in the row direction and are parallel to the signal line source, and the second scan lines G2 extend in the row direction and are arranged in the column direction, and each first scan line G1 intersects and connects with the corresponding second scan line G2. The second connection ends of the first light emitting unit 41 and the second light emitting unit 42 are electrically connected to the second scan line G2.

[0052] Furthermore, the display panel further includes a plurality of first pixel columns C1 and a plurality of second pixel columns C2, the first pixel column C1 includes a plurality of first light emitting units 41 distributed along the column direction, the second pixel column C2 includes a plurality of second light emitting units 42 distributed along the column direction, the first pixel column C1 and the second pixel column C2 are staggered along the row direction, and the signal line source is located between adjacent first pixel columns C1 and second pixel columns C2. The plurality of first light emitting units 41 and the plurality of second light emitting units 42 are arranged in an array to form a plurality of pixel rows R1, each pixel row R1 includes a first light emitting unit 41 and a second light emitting unit 42 staggered along the row direction, and two second scan lines G2 are provided between two adjacent pixel rows R1.

[0053] like Figure 3 and Figure 4 As shown, the first light emitting unit 41 has the same structure as the second light emitting unit 42, that is, each light emitting unit 4 includes a first transistor TFT1, a second transistor TFT2 and a storage capacitor Cst. The first transistor TFT1 is a data writing transistor, the second transistor TFT2 is a driving transistor, and the storage capacitor Cst is used to store data voltage.

[0054] The control end (i.e., gate) of the first transistor TFT1 is connected to the scan line (Gate), the first end (i.e., source or drain) of the first transistor TFT1 is connected to the signal line source, the second end (i.e., source or drain) of the first transistor TFT1 is connected to the control end (i.e., gate) of the second transistor TFT2, the second end (i.e., source or drain) of the second transistor TFT2 is connected to the first power line ELVDD, the first end (i.e., source or drain) of the second transistor TFT2 is connected to the OLED light-emitting device, and the cathode of the OLED light-emitting device is connected to the second power line ELVSS. The first end of the storage capacitor Cst is connected to the second end of the second transistor TFT2, and the second end of the storage capacitor Cst is connected to the control end of the second transistor TFT2.

[0055] It should be noted that the second power line ELVSS is uniformly connected to the cathode covering layer of the light-emitting device and is used to transmit a low negative power signal or a low-level power signal. Its material is a stack of at least one or more conductive materials such as metal aluminum Al, lithium fluoride LiF, and metal magnesium Mg. The first power line ELVDD is used to transmit a positive power signal or a high-level power signal.

[0056] The first transistor TFT1 and the second transistor TFT2 are not limited to specific semiconductor materials. Specifically, when the pixel density PPI is low and the space of the lower frame 3 (border) of the display screen is large, semiconductor materials such as a-Si (amorphous silicon) or IGZO (indium gallium zinc oxide) can be used; when the pixel density PPI is high and the lower frame 3 (border) of the display screen is narrow, Poly-Si (polycrystalline silicon) can be used, and of course LTPO (Low Temperature Polycrystalline Oxide), that is, low-temperature polycrystalline oxide technology, can also be used.

[0057] like Figure 2 , Figure 3 and Figure 4 As shown, a first light emitting unit and a second light emitting unit 42 are respectively provided on both sides of the same signal line source, and the first ends of the first transistors TFT1 in the first light emitting unit 41 and the second light emitting unit 42 are simultaneously connected to the signal line source. HSD (Half source design, half source drive) technology can be adopted here, so that the wiring amount of the signal line source can be reduced by half compared with the original technology. For example, originally 2n signal lines source are required to be arranged in the display area, but after adopting HSD (Half source design, half source drive) technology, only n signal lines source are required to be arranged in the display area.

[0058] Furthermore, the display panel further includes a data line data, which is electrically connected to the driver chip, and is used to transmit a display signal sent by the driver chip to the display device in the display area. The signal line source includes a first signal line S1 and a second signal line S2, and a first pixel column C1 and a second pixel column C2 are provided between adjacent first signal lines S1 and second signal lines S2. The first signal line S1 is parallel to the second signal line S2, and the ends of the first signal line S1 and the second signal line S2 leading out of the display area are connected to the data line data in a time-sharing manner.

[0059] The display panel further includes a first switch transistor T1 and a second switch transistor T2. A first end of the first switch transistor T1 is connected to a first signal line S1, and a second end of the first switch transistor T1 is connected to a data line data. A first end of the second switch transistor T2 is connected to a second signal line S2, and a second end of the second switch transistor T2 is connected to the data line data. Control ends of the first switch transistor T1 and the second switch transistor T2 are connected to different control signal lines.

[0060] like Figure 3As shown, a mux (multiplexing) circuit is used below the display area, that is, a data line data is set, and the data line data is connected to two signal lines source drawn from the display area, so that the two signal lines source are controlled simultaneously by one data line data, which can further reduce the lower frame space occupied by the data line data, and achieve the effect of an extremely narrow lower frame 3 of the display screen. Specifically, after receiving the corresponding display signal, the data line date turns on the corresponding switch transistor and transmits the display signal to the corresponding signal line source. For example, after receiving the corresponding display signal, the data line date turns on the first switch transistor T1 and keeps the second switch transistor T2 off, so that the display signal is transmitted to the first signal line S1, and is transmitted to the corresponding light-emitting unit through the first signal line S1, and because the second switch transistor T2 is kept on, the display signal will not be mistakenly transmitted to other pixel columns.

[0061] It should be noted that the above-mentioned mux circuit is a mux2 (one data line data controls two signal lines source) circuit, but in other embodiments of the present invention, it is not limited to this. The mux circuit can also be a mux3 (one data line data controls three signal lines source) circuit or a mux4 (one data line data controls four signal lines source) circuit, etc., and multiple mux circuits can also be used in combination according to actual needs, for example, setting the mux2 circuit and the mux3 circuit at the same time, or setting the mux3 circuit and the mux4 circuit at the same time.

[0062] like Figure 5 As shown, the cross-intersection positions of the scan lines Gate arranged horizontally and vertically in the display area are connected by digging holes in the metal wire layer 5 to achieve cross-line and avoid short circuit. The metal wire layer is the signal line source.
