Embodiment Construction

[0027] Among the reflective products with front light, the narrowest bezel of the currently listed products is 3.36mm. Because the bezel is too narrow, the distance between the AA display area and the outer edge of the LGP (light guide plate) is too short, and the touch screen is too narrow. TP ink cannot cover all the light leaking from the edge of the front light guide plate, resulting in bright lines, light leakage, and dark bands on the edge (especially the non-incidence surface), which seriously affects the user experience of end customers, especially in dark images and dark environments. Obviously, the glare of light destroys the soft paper reading experience of electronic paper and RLCD (Reflective Liquid Crystal Display). Other reading reflective products, such as e-book readers, RLCD readers, in order to avoid the problem of light leakage at the top, left and right sides, and bottom, adopt the scheme of increasing the four-sided border and increase the coverage width o...

Abstract

The invention relates to the field of display, and discloses an electronic device, which includes a cover plate, a first optical adhesive layer, a light guide plate, a second optical adhesive layer, and a display module stacked in sequence; the light guide plate has a light incident side, a light exit end, and a connection The first side light outlet and the second side light outlet of the light incident side and the light outlet, wherein the light outlet is opposite to the light incident side, the first side light outlet is opposite to the second side light outlet; the first side light outlet and / or the second side A third optical adhesive layer is provided on the edge of the side light emitting end, and the refractive index of the third optical adhesive layer is similar to that of the light guide plate. After the light enters the third optical adhesive layer from the light guide plate, the light will not be greatly scattered at the junction, which reduces the light shining on the top cover, the lower display module and other positions, thereby reducing the reflection from the above parts to AA The light in the display area prevents the light from entering the AA display area and affecting the display effect.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 202110009466.8 and the application name "An electronic device" filed with the China Patent Office on January 5, 2021, the entire contents of which are incorporated into this application by reference. technical field [0002] The present invention relates to the field of display technology, and in particular, to an electronic device. Background technique [0003] With the continuous improvement of users' requirements for the appearance of portable electronic products such as mobile phones and readers, the screen ratio of mobile phones, readers and other products is getting higher and higher, and the borders on the four sides are getting narrower and narrower. As the border of the front light guide plate is getting narrower and narrower, the problems of light leakage, bright lines and dark bands appearing on the four sides of the front light guide plate are becoming more an...
