Problems solved by technology

[0002] like figure 1 As shown, the OLED light-emitting panel includes a display area 1 and a frame area 2. The frame area 2 includes an upper frame 21, a lower frame 22, a left frame 23, and a right frame 24. Metal wiring 3 is provided in the frame area. The cathode of the display area 1 11 extends to the left frame 23 and the right frame 24, wherein the metal wire 3 is used to transmit signals to the cathode 11, and the current transmitted by the external circuit to the OLED through the metal wire is directly related to the display brightness of the screen, so in order to reduce Impedance, the metal trace 3 is usually wide and circles around the display area, especially for large-sized display devices, its line width occupies half of the frame, thus occupying a larger position around the frame of the OLED display, which in turn increases the OLED monitor border

Embodiment 1

[0025] figure 2 The frame area 2 in the display area 2 includes an upper frame 21, a lower frame 22, a left frame 23, and a right frame 24. The metal wires 3 are respectively arranged in the upper frame 21 and the lower frame 22. The cathode (not shown in the figure) in the display area 1 out) is connected to the metal trace 3 through the anode. Both ends of the line 3 are electrically connected. Of course, according to different frame structures of the OLED display panel, the metal wires 3 can also be arranged on the left and right frames, and the conductive tape can be used instead of the metal wires in the upper and lower frames, so that the upper and lower frames can be made narrower.

[0026] Here, the conductive tape 4 can be bonded to cover the blank area on the back of the display area 1, using a fully covered structure or a partially covered structure, thereby reducing the impedance and ensuring that the metal traces can transmit sufficient current to the OLED displ...

Embodiment 2

[0029] Different from Embodiment 1, in this embodiment, a raised structure 41 is formed on the upper and lower ends of the conductive tape 4 on the left frame 23 and the right frame 24 respectively, as image 3 As shown, the protruding structure 41 is located at both ends of the upper frame 21 and the lower frame 22 , and forms an electrical connection with the metal wiring 3 .

[0030] The width of the protruding structure 41 is greater than the width of the metal trace 3 . Compared with the width of the metal traces in the upper and lower frames, the conductive tape is wider to ensure that the ends of the metal traces are completely covered by the conductive tape, and because the conductive tape covers the blank area on the back of the OLED display panel, reducing the The small impedance ensures that the metal traces transmit enough current to the OLED display area, thus ensuring the brightness of the display.

[0031] Preferably, the upper end of the conductive tape 4 is f...

Abstract

The invention discloses an OLED display panel with a narrow frame structure, which includes a display area and a frame area located around the display area, one of the opposite frames in the frame area is provided with metal wiring, and the cathode in the display area is connected to the metal through the anode. Wire connection, the back of the display area is provided with a conductive tape, and the two ends of the conductive tape are respectively electrically connected to the two ends of the metal wires in the two opposite frames after being bent. In the present invention, a conductive tape is pasted on the back of the OLED display panel, and the conductive tape is bent from the left and right sides of the display panel to one of the opposite frames, and the conductive tape is respectively connected to the two ends of the metal wiring on the other opposite frame. The conductive tape replaces the metal wiring on one of the opposite frames, making the size of the frame area narrower and increasing the size of the display area.

Description

technical field [0001] The invention relates to the technical field of OLEDs, in particular to an OLED display panel with a narrow frame structure. Background technique [0002] Such as figure 1 As shown, the OLED light-emitting panel includes a display area 1 and a frame area 2. The frame area 2 includes an upper frame 21, a lower frame 22, a left frame 23, and a right frame 24. Metal wiring 3 is provided in the frame area. The cathode of the display area 1 11 extends to the left frame 23 and the right frame 24, wherein the metal wire 3 is used to transmit signals to the cathode 11, and the current transmitted by the external circuit to the OLED through the metal wire is directly related to the display brightness of the screen, so in order to reduce Impedance, the metal trace 3 is usually wide and circles around the display area, especially for large-sized display devices, its line width occupies half of the frame, thus occupying a larger position around the frame of the O...
