Problems solved by technology

Furthermore, when the bonding area is too large, it will affect the appearance quality of the display screen. If it is used for splicing screen applications, there will be obvious seams, which will affect the effect of splicing display.
Since polyimide, the chip-on-chip film or flexible circuit board substrate, has good resilience, it is not easy to bend, and it will also increase the seam, which will affect the effect of the splicing display

Abstract

The invention provides a spliced display screen. The spliced display screen comprises a plurality of panels and a plurality of chip-on-films. Each panel comprises a display surface and a back surfacewhich are oppositely arranged, and the direction from the display surface to the back surface is a first direction. Each chip-on-film comprises a first surface and a second surface which are oppositely arranged, and the direction from the first surface to the second surface is a second direction. One chip-on-film is clamped between every two adjacent panels. The first direction is perpendicular tothe second direction. One chip-on-film is clamped between every two adjacent panels, so that the space occupied by insufficient bending of the chip-on-films is reduced, the width of the bonding areais reduced, and the splicing seam between every two adjacent panels is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a spliced ​​display screen. Background technique [0002] At present, traditional display screens need to input the signals required by the panel into the panel through the module process of bonding film on chip or flexible circuit board. Because of the panel design, it is usually necessary to bundle the in-plane signal lines through the fan-shaped area first, concentrate them in a small binding area, and then bind the chip-on-chip or flexible circuit board to the binding area. On the printed circuit board Form an electrical connection with the glass substrate, so that the width of the bonding area is usually large. Furthermore, if the bonding area is too large, it will affect the appearance quality of the display screen. If it is used for splicing screens, there will be obvious seams, which will affect the effect of splicing display. Since polyimide, the chip-on-chi...
