Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] see figure 1 , figure 1 It is a structural schematic diagram of an existing light guide plate. The light guide plate is one of the most important optical components in the side-emitting backlight. At present, most of them are made of acrylic material, and the thickness is between 3 and 6mm. figure 1 As shown, the blank rectangle 1 represents the LED that is lit, the black rectangle 2 represents the LED that is not lit, the dotted box is the ideal light spot, and the curve is the actual light spot. It can be seen that due to the overall uniformity of the material, the light spot...

Abstract

The invention discloses a quantum dot light guide plate, a backlight module, and a liquid crystal television. The quantum dot light guide plate comprises a rectangular light guide plate, the rectangular light guide plate comprises a first side surface, a second side surface, a third side surface, a fourth side surface, and a light-outlet surface and a backlight surface arranged in an opposite manner, the light-outlet surface is provided with a quantum dot layer including red quantum dots and green quantum dots, the first side surface of the rectangular light guide plate is provided with at least a light source hole used for placing a blue light LED, and the backlight surface, the second side surface, the third side surface, and the fourth side surface are respectively provided with reflective layers. According to the quantum dot light guide plate, the backlight module, and the liquid crystal television, the color gamut range is greatly expanded, the color expression is good, and the energy-saving effect is good.

Description

technical field [0001] The invention relates to the technical field of light guide plates, in particular to a quantum dot light guide plate, a backlight module and a liquid crystal television. Background technique [0002] Side-emitting LED TVs can be lighter and thinner than direct-lit LED TVs, and have certain cost advantages. Therefore, side-emitting LED ultra-thin LCD TVs have become mainstream products in the market. However, this side-emitting LED LCD TV has the following disadvantages: white LEDs are mostly obtained by exciting yellow phosphors with blue LEDs, which have disadvantages such as impure color and poor color performance; all LEDs are integrally driven to emit light as a whole, which TVs do not have With the regional dimming function, the power consumption of the backlight source is fixed, which is not energy-saving and environmentally friendly; even though the LEDs are independently driven and have the regional dimming function, the light guide plate is an...
