Problems solved by technology

[0004] However, since the bracket and the heat dissipation layer are only fixed by foam glue, the fixed end of the bracket will exert pressure on the protective film during the clamping process, which will cause deformation of the copper foil attached to the heat dissipation layer, and then Print marks are formed on the display device panel; at the same time, in order to prevent the formation of print marks on the display device panel when removing the flexible circuit board bracket, it is necessary to use a standardized tearing method, but manual operations are prone to errors, which will cause damage to the display device panel

Abstract

The invention provides a display screen and a display device. The display screen comprises a cover plate, a support and a circuit board attached to the cover plate and located between the cover plate and the support. A protective film is arranged on the outer surface of one side, far away from the support, of the cover plate; the support comprises a fixed end and a supporting end, the fixed end of the support is fixed to the protective film, a protrusion is arranged on the side, close to the circuit board, of the supporting end of the support, and the protrusion abuts against the circuit board. The fixed end of the support is fixed to the protective film, and the supporting end of the support abuts against the circuit board, so that the situation that the support makes direct contact with a flexible device of the display screen, and consequently the display screen has impressions is avoided, losses are reduced, and the service life of the display screen is prolonged.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display screen and a display device. Background technique [0002] In electronic products such as mobile phones and tablet computers, flexible circuit boards are an important component, and are generally fixed on the outer surface of the product through a specific structure. [0003] In the prior art, the flexible circuit board is fixed in the display device by a bracket. Usually, the bracket includes a fixed end and a support end, wherein the fixed end of the bracket is fixed on the heat dissipation layer (SCF) of the display device, The support end of the bracket is provided with a protrusion, and the protrusion abuts against the no-component area (FPC) of the flexible circuit board, thereby forming a lever structure to protect the flexible circuit board and the binding bending area in the display device , to prevent damage to the flexible circuit board and the bi...
