Abstract

The invention provides a display screen which comprises a bearing layer, a display panel and an adhesive portion. The display panel is provided with a bent portion, and the adhesive portion is used for fixing two ends of the bent portion of the display panel. The invention also provides a display screen. The display screen comprises a display panel, a buffer layer, a driving chip, a bonding portion and a flexible circuit board, wherein the flexible circuit board is provided with a bent portion, and the bonding portion is used for fixing the two ends of the bent portion of the flexible circuitboard. By arranging the adhesive portion or the bonding portion for the display screen, the two ends of the bent portion of the display screen can be prevented from being peeled off, and the yield ofthe display screen is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display screen. Background technique [0002] With the development of display technologies, display screens with narrow borders are becoming more and more popular. Among them, the display packaging technology that can realize narrow frame includes COF (Chip on Film, chip on film) technology and COP (Chip on Pi, chip packaging on flexible substrate) technology. [0003] In the COF process, the FPC (Flexible Printed Circuit, flexible circuit board) is arranged on the display panel, and the driver IC (Integrated circuit, chip) is fixed on the FPC. After the FPC is bent, the driver IC is arranged under the display screen. The COP process directly arranges the driver IC on the flexible display panel, and then bends the flexible display panel to also arrange the driver IC under the display screen. [0004] For the above-mentioned display screen manufactured by the COF process or t...
