Abstract

The invention provides a display panel which comprises a display panel body and at least two driving circuits. The display panel body comprises data wires, scanning wires, pixel units which are formed through intersection of the data wires and the scanning wires, and a circuit board wiring which is used for different driving circuit boards. Each driving circuit board comprises a circuit board body, a first bridging wire and a second bridging wire, wherein the second bridging wire is connected with the circuit board wiring on the display panel body and the circuit board body for transmitting a cascading signal. The first bridging wire is connected with the data wires and scanning wires on the display panel body, and the circuit board body and is used for transmitting a data signal and a scanning signal in response to the cascading signal. The invention further provides a display device. According to the display panel and the display device, different driving circuit boards are connected through the second bridging wire and the circuit board wiring, thereby reducing manufacturing cost of a driving circuit board connecting device and furthermore reducing manufacturing cost of the corresponding display panel.

Description

technical field [0001] The invention relates to the field of display driving, in particular to a display panel and a display device. Background technique [0002] Due to upgrading, the current display panel manufacturers are using larger and larger glass substrates, and the size of the display panels they produce is also increasing, such as 65 inches, 85 inches, and 110 inches. The larger the size of the display panel, the larger the area of ​​the driving circuit board used in conjunction with it. [0003] However, due to the limitation of the production process of the printed circuit board, the maximum size of the existing drive circuit board can only be about 600mm. Therefore, when the display panel is large in size, multiple drive circuit boards are often installed. For details, please refer to figure 1 , figure 1 It is a structural schematic diagram of an existing display panel. The display panel 10 includes a display panel main body 11 and a first driving circuit boa...
