Abstract

The invention is suitable for the technical field of display panels, and provides a display panel and a display device.According to the display panel, a lead connecting structure on an array substrate protrudes out of a color film substrate to form a direct connecting part, and a circuit board and the color film substrate are arranged side by side, so that the circuit board and the array substrate are directly connected to complete electric transmission; therefore, a COF structure is omitted, the frame width of the panel can be greatly reduced, the frame of the display equipment can be made to be narrower than that in the prior art, the omitted COF structure also avoids the problems that the COF is prone to connection failure and falling off. Meanwhile, the material cost and the manual assembly cost of the COF are omitted, and mounting and dismounting are convenient.

Description

technical field [0001] The present application belongs to the technical field of display panels, and more specifically relates to a display panel and a display device. Background technique [0002] Existing display panels usually form a complete whole by thermally bonding CELL (screen module), COF (chip on flex film), and PCBA (Printed Circuit Board Assembly). Structured display panels have significant limitations. [0003] At present, what the wallpaper TV is pursuing is the ultimate thinness. In order to achieve this effect, components such as the motherboard and power board that will affect the thickness of the whole machine are usually placed in the main box outside the backplane. Similarly, the PCBA cannot be installed in the backplane. behind the board, but rests flat on the backplane. Make PCBA and display glass design on the same plane, then the width of PCBA and COF will directly affect the frame width of the whole machine, making the frame width limited. Moreove...
