Problems solved by technology

In addition, there is a certain distance between the light-emitting surface of the LED lamp and the light guide plate in the assembled state, so that only part of the light emitted by the LED lamp can enter the light guide plate and be used, which will not only waste the energy of the light source, but also affect the backlight. Brightness; at the same time, due to the assembly error in the process of assembling the LED to the light bar, it will cause the light-emitting surface of the LED lamp and the light-incoming surface of the light guide plate to be out of alignment, so the light emitted by the LED lamp cannot effectively enter the light guide plate, resulting in backlight Source Brightness and Uniformity Reduction

Embodiment Construction

[0019] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0020] The present invention firstly provides a light guide plate with a structure such as figure 2 As shown, a groove for accommodating at least a part of LED lamps is provided on the light incident side of the light guide plate 200 .

[0021] It can be seen from the above that the light guide plate provided by the present invention has a groove for accommodating the LED lamp. The LED lamp is assembled in the groove, and the distance between the light guide plate and the light guide plate is shortened. At the same time, the contact area between the LED lamp and the light guide plate is Increase, so that the light emitted by the LED lamp can enter the light guide plate more, so that the brightness of the backlight module using this light guide plate can...

Abstract

The invention provides a light guide plate, a backlight module group, and a display device. A light incoming side of the light guide plate is provided with a groove for storing at least a part of LED lamps. The backlight module group comprises the light guide plate provided by one embodiment of the invention. The display device comprises the backlight module group provided by one embodiment of the invention. The light guide plate, the backlight module group and the display device can improve the light utilization rate of the LED lamps.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide plate, a backlight module and a display device. Background technique [0002] In the side-illuminated backlight structure commonly used in the prior art, such as figure 1 As shown, the light incident side 101 of the light guide plate is a plane. In addition, there is a certain distance between the light-emitting surface of the LED lamp and the light guide plate in the assembled state, so that only part of the light emitted by the LED lamp can enter the light guide plate and be used, which will not only waste the energy of the light source, but also affect the backlight. Brightness; at the same time, due to the assembly error in the process of assembling the LED to the light bar, it will cause the light-emitting surface of the LED lamp and the light-incoming surface of the light guide plate to be out of alignment, so the light emitted by the LED lamp cannot effecti...
