Abstract
The invention provides an LED device, a backlight module and a display device, wherein the LED device includes: a support structure and a chip, the support structure has a cup cavity, and the chip is installed in the cup cavity; a package structure, the package structure is covered by the support structure The cup cavity is sealed above, and the upper surface of the packaging structure away from the cup cavity forms a light-emitting surface; the reflective shielding layer, the reflective shielding layer is arranged on the packaging structure, the reflective shielding layer is located at the center of the light-emitting surface and covers a part of the light-emitting surface, so that The luminous intensity of the LED device is uniformly distributed along the light-emitting surface. The invention solves the problem that the display device in the prior art cannot take into account the excellent color saturation and light-dark contrast of the display screen and the good economical efficiency of the display device.
Description
technical field [0001] The present invention relates to the technical field of LED lighting, in particular to an LED device, a backlight module and a display device, wherein the structure of the LED device is mainly improved. Background technique [0002] In recent years, high-end display technology has been committed to improving the display quality of display devices, making the bright field of the display screen brighter and the dark field darker, achieving a higher contrast between light and dark, so that any details in the display screen can be vividly displayed. displayed to enhance the user's viewing experience. [0003] In order to further improve the image quality, especially for the poor contrast performance that is often criticized by the OLED camp, the LCD industry has begun to widely adopt Local Dimming backlight technology to achieve HDR functions, thereby greatly improving the contrast performance to reach the same level as OLED. Therefore, the Mini LED backl...
