Liquid crystal display device and method for achieving high color gamut through quantum tube

Abstract

The invention provides a liquid crystal display device for achieving a high color gamut through a quantum tube. A light guide plate and a quantum tube are changed into a special-shaped structure, and an LED lamp strip and the quantum tube form a light-emitting source to a backboard at the bottom side of the liquid crystal display device, so that a plurality of side surfaces are formed between corresponding bottom surfaces and side surfaces of the light guide plate and the light-emitting source; through arrangement of the plurality of side surfaces inclining inwards relative to the top surface, an included angle smaller than 90 degrees is formed between a light inlet surface of the light guide plate and the top surface; and light emitted from the light-emitting source is reflected to the light inlet surface of the light guide plate through a side reflector plate or directly irradiates the light inlet surface of the light guide plate, and then enters the inside of the light guide plate from the light inlet surface. The special-shaped structure is adopted by the light guide plate of the liquid crystal display device, so that the light inlet surface of the light guide plate is obliquely arranged and the narrow-edge, ultrathin and borderless design of a backlight module is further achieved; and furthermore, the light guide plate can be fully fixed through a form method and the damage to a light-emitting source element after thermal expansion is reduced.

Description

technical field [0001] The invention relates to the display field, in particular to a liquid crystal display device realizing high color gamut by quantum tubes, and also relates to a method for realizing high color gamut by quantum tubes. Background technique [0002] With the continuous development of technology, consumers have higher and higher requirements for LED LCD TVs. The structural forms of "ultra-narrow" (ultra-narrow frame), "ultra-thin" (ultra-thin thickness) and "bezel-less" have become LED LCD TVs. The new development trend of TV, in addition, the pursuit of color gamut standards is gradually increasing, which has become an important indicator of competition in the industry. [0003] An existing liquid crystal display device includes a liquid crystal screen and a backlight module for providing backlight for the liquid crystal screen. The backlight module includes an optical film and a light source assembly. In order to meet the requirements of high color gamut...
