Problems solved by technology

When the LED chip is lit for a long time, the temperature of the LED chip is high, so that the temperature of the quantum dot material in the encapsulant increases, which in turn affects the stability of the quantum dot material, resulting in color deviation

Embodiment Construction

[0014] The embodiment of the present invention provides an LED and a display device. Since the quantum dot material capable of emitting light under the illumination of the LED chip is doped in the LED lampshade far away from the LED chip, the temperature of the LED chip subjected to the quantum dot material is affected. The impact is small, thereby reducing the color deviation of LED light emission and improving the display quality.

[0015] Such as figure 1 As shown, the LED provided by the embodiment of the present invention includes:

[0016] Light emitting diode LED chip 101, potting glue 102 potted on the LED chip and LED lampshade 103 covered on the potting glue, wherein:

[0017] The LED lampshade is doped with quantum dot material 104 capable of emitting light under the illumination of the LED chip 101 .

[0018] The LED can be used as a light source in a liquid crystal display device, and can also be used as a light source in a lighting device.

[0019] Usually, th...

Abstract

The invention discloses an LED and a display device, and relates to the display techniques. Due to the fact that quantum dot materials which can emit light under illumination of an LED chip are doped in an LED lamp cover which is far away from the LED chip, the influence of the temperature of the LED chip on the quantum dot materials is small, the color deviation of light emitting of the LED is reduced, and the quality of displaying is improved.

Description

technical field [0001] The invention relates to display technology, in particular to an LED and a display device. Background technique [0002] At present, in a display device, especially a liquid crystal display device, the backlight source is usually realized by using LED (Light Emitting Diode, light emitting diode) to emit light. [0003] The principle of LED light emission is: the LED chip is a blue chip, and quantum dot materials are doped in the potting glue. After the blue light emitted by the LED chip irradiates the quantum dots, it excites the quantum dot materials to emit red and green light, thereby achieving a white light effect. . [0004] However, the current quantum dot materials are all filled in potting glue, and the potting glue is potted on the LED chip. When the LED chip is lit for a long time, the temperature of the LED chip is high, so that the temperature of the quantum dot material in the encapsulant increases, which in turn affects the stability of...
