Abstract

An embodiment of the invention discloses a clamping and fixing method and a display device. The method includes: a plastic frame, a back plate, an optical diaphragm and a light guide plate are provided, the plastic frame comprises a first clamping portion with fixing columns, the back plate comprises a second clamping portion with through holes corresponding to the fixing columns, and the size ofthe through holes is larger than that of the fixing columns; the optical diaphragm and the light guide plate are assembled between the first clamping portion and the second clamping portion, and the fixing columns penetrate the through holes; portions, extending out of the through holes, of the fixing columns are subjected to hot melting to obtain hot molten portions covering the through holes, and accordingly the optical diaphragm and the light guide plate are fixedly clamped by the first clamping portion and the second clamping portion. Since optical diaphragm and the light guide plate in abacklight module are fixedly clamped by the first clamping portion and the second clamping portion, image display abnormality of the display device due to curved surface stress resilience is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a clamping and fixing method and a display device. Background technique [0002] Curved surface display devices are becoming more and more popular due to their good viewing angle and aesthetic appearance. However, the current curved display device mainly relies on the plastic frame and the back plate to clamp the optical film and the light guide plate. Under the action of the elastic force of the curved surface of the optical film and the light guide plate, it is easy to cause the rebound of the light guide plate, the plastic frame and the optical film, resulting in the problem of uneven brightness and darkness of the picture, which seriously affects the user experience. Contents of the invention [0003] Embodiments of the present invention provide a clamping and fixing method and a display device to solve the problem of uneven brightness and darkness of the picture caused b...
