Problems solved by technology

However, the cost of this solution is particularly high, and the effect of blocking water and oxygen is poor
Experiments have also proved that this kind of scheme has very poor implementation effect due to the anisotropy of quantum dot materials.

Abstract

The invention discloses a backlight source and an optical module. The backlight source comprises an LED and a lens arranged in the light-emitting direction of the LED in a covering mode. The lens is asplit type lens and comprises a base and an upper cover. The LED is accommodated in the base, the upper cover is arranged on the base, quantum dots are arranged on a contact surface between the baseand the upper cover, and the upper cover arranged on the base seals the quantum dots arranged on the contact surface. The invention further provides a backlight module with the backlight source. According to the backlight source and the backlight module, the lens in the backlight source is designed in a split mode, and the quantum dots are arranged on the contact surface of the base and the uppercover, so that the requirement for improving the color gamut is met, the consumption of quantum dot materials can be reduced, the requirement for low cost is met, and the color uniformity effect of liquid crystal display can be improved.

Description

technical field [0001] The invention relates to the field of backlights, in particular to a backlight source capable of realizing a high color gamut and a backlight module. Background technique [0002] With the improvement of consumers' requirements for display quality, the display industry has set off a wave of high color gamut in recent years, and quantum dot materials have been used by the entire display industry due to their small half-wave width, high luminous purity, and high color gamut display. attention of the industry. However, quantum dot materials have the disadvantages of being expensive, easy to oxidize, afraid of water, and afraid of high temperature. However, in order to achieve ultra-high color gamut effects, quantum dot materials have to be used in some backlight solutions. How to reduce the cost on the premise of ensuring the color gamut has become a problem that everyone in the display industry is working hard to study. [0003] The current common sol...
