Problems solved by technology

However, in order to realize the design of large screen and super large screen, the existing technical solution is to design a narrower frame and further design a narrower plastic frame
However, the clamping and fixing effect of the narrow plastic frame on the optical diaphragm will be weakened, which usually causes part of the light emitted by the light source to enter the optical diaphragm and then spread out, forming a light leakage phenomenon

Abstract

The invention discloses an optical membrane layer, a backlight module and a display device. A black shading area is arranged on the end portion of the optical membrane layer to prevent light rays emitted by a light source from entering into the optical membrane layer from the end portion. By using the mode, the optical membrane layer, the backlight module and the display device can prevent partial light rays emitted by the light source from entering into the optical membrane layer to generate light leak, and thus display quality of the display device, particularly a narrow frame display device can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an optical film layer, a backlight module and a display device. Background technique [0002] With the advancement of science and technology, display technology is becoming more and more advanced, especially the development of liquid crystal display, which has penetrated into all aspects of people's lives. The current liquid crystal display has realized the design of large screen and super large screen. Such a fashionable and beautiful design can not only give people a better visual experience, but also become a beautiful fashion decoration. However, in order to realize the design of large screen and super large screen, the existing technical solution is to design a narrower frame and further design a narrower plastic frame. However, the clamping and fixing effect of the narrow plastic frame on the optical film will be weakened, usually causing part of the light emitted by the ...
