Light guide plate with supporting rib and display module comprising same

Abstract

The invention relates to a light guide plate with a supporting rib and a display module comprising the same. The light guide plate is used for a backlight module. The light guide plate comprises a light exiting region and a light shading region, wherein the light shading region is arranged at one side of the light exiting region, at least protrudes out of the plane of the light exiting region, the light exiting region is formed by the body of the light guide plate, the body comprises a light exiting surface and a first end having a first thickness, the light shading region comprises at least part of the supporting rib of the light guide plate, the supporting rib is arranged at the first end of the body and extends along the first end, at least part of the supporting rib protrudes out of the light exiting surface, at least part of the supporting rib is formed by non-transmitting bodies, the supporting rib has a shading width inward from the first end, and the shading width is no smaller than the first thickness. The light guide plate can avoid bright lines or leaked light caused by border refracted light.

Description

technical field [0001] The invention relates to a design of a light guide plate; specifically, the invention relates to a light guide plate with supporting ribs. Background technique [0002] Liquid crystal display devices (Liquid Crystal Display, LCD) are widely used in various electronic products such as computers, televisions, and mobile phones. Among them, the light guide plate is applied to the backlight module of the liquid crystal display, and is an important component affecting the use efficiency of light in the display device; the light guide plate can guide the light direction, improve the luminance, and control the brightness uniformity. On the other hand, the display device also tends to become thinner and lighter with the progress of the display device industry technology and the needs of life. Therefore, in line with the evolution of the appearance of the display device, the internal components seek to exert equal or even better effects with their limited volu...

Problems solved by technology

However, when the display module 1b adopts a narrow frame design, such as Figure 1B As shown, the distance C between the edge of the light guide plate 12b of the backlight module and the screen display area 22 is closer, and the bright line or light leakage caused by the refracted light L of the frame cannot be avoided.

On the other hand, when the use of the plastic frame is omitted and the Figure 1C When the light guide plate frame 3c is used to support the display panel, the light is easy to gather in the support structure 30c of the light guide plate frame 3c, thus causing bright lines and light leakage
