Problems solved by technology
[0004] Firstly, the high price of the level shifter, coupled with the complexity of the peripheral devices that match the level shifter, lead to an increase in the manufacturing cost of the panel in the prior art
Furthermore, as the number of clocks on the gate array substrate changes, it is often impossible to find a level shifter for direct use. Often, multiple level shifters and corresponding peripheral circuit designs are required to complete the display panel, which affects the flexibility of design. sex
In addition, the panel in the prior art cannot change the scanning direction of the gate drive circuit

Provided in the invention is a display panel comprising a gate electrode array substrate, a first flexible circuit board connected with the gate array substrate, a printed circuit board connected withthe first flexible circuit board, a second flexible circuit board arranged on the side edge of the gate array substrate, and a level shifter. The printed circuit board is provided with a central control board, and the central control board outputs a gate array driving signal; and the level shifter is arranged on the second flexible circuit board and is electrically connected with the central control board, and the level shifter uplifts a gate array driving signal, so that the effects of reducing the manufacturing cost of the panel, improving the design flexibility of the panel and controllingthe scanning direction of the gate driving circuit are achieved.
Description
【Technical field】 [0001] The present disclosure relates to the field of display technology, in particular to a display panel. 【Background technique】 [0002] see figure 1 , which is a schematic block diagram of a display panel including a gate driving circuit in the prior art. Such as figure 1 As shown, in the display panel 100, a chip on film (chip on film, COF) 120 is disposed between the printed circuit board 110 and the gate array substrate GOA1, the level shifter 111 is disposed inside the printed circuit board 110, and the gate The array substrate GOA1 is electrically connected to the level shifter 111 . [0003] However, the prior art has the following defects: [0004] Firstly, the high price of the level shifter, coupled with the complexity of peripheral devices matching the level shifter, lead to an increase in the manufacturing cost of the prior art panel. Furthermore, as the number of clocks on the gate array substrate changes, it is often impossible to find...
