Problems solved by technology

[0002] The backlight is the light source provider of the display device and one of the important components of the LCD. The color gamut of the light emitted has a great influence on the display effect. The existing backlight generally uses "blue LED + yellow phosphor" to induce white light. , replacing the traditional cold cathode ray tube, greatly improving its luminous efficiency; under the same brightness conditions, the power of the backlight is greatly reduced; and the color gamut has been improved to a certain extent, but the color gamut of the existing backlight The range is far from meeting the requirements of the LED display field

Abstract

The invention relates to the field of LED display, in particular to a backlight source and a display device. The backlight source comprises a supporting frame, an excitation light source and a quantum dot membrane, wherein the supporting frame is provided with a groove with an opening, the excitation light source is arranged in the groove, the edge of the quantum dot membrane is fixed to the supporting frame and closes the opening. The display device adopts the backlight source. The backlight source and the display device have the advantage of having a wide color gamut range.

Description

【Technical field】 [0001] The invention relates to the field of LED display, in particular to a backlight source and a display device. 【Background technique】 [0002] The backlight is the light source provider of the display device and one of the important components of the LCD. The color gamut of the light emitted has a great influence on the display effect. The existing backlight generally uses "blue LED + yellow phosphor" to induce white light. , replacing the traditional cold cathode ray tube, greatly improving its luminous efficiency; under the same brightness conditions, the power of the backlight is greatly reduced; and the color gamut has been improved to a certain extent, but the color gamut of the existing backlight The range is far from meeting the requirements of the LED display field. [0003] Therefore, how to provide a backlight with a wide color gamut has become a demand in the LED display field! 【Content of invention】 [0004] In order to overcome the tec...
