Description
Technical Field
The utility model relates to the field of MINI LED backlight quantum dot liquid crystal display, in particular to a direct type MINI-LED quantum backlight module capable of preventing blue light from leaking laterally.
Background
In recent years, Mini-LED display products with lower technical threshold compared with Micro-LEDs are developed vigorously, and a Mini-LED backlight and liquid crystal glass display ultra-high definition product combining a quantum dot technology and a backlight large-scale partition technology appears in the market. The picture quality of the OLED is not inferior, but the cost, reliability and service life of the OLED are lower and higher. The MINI LED quantum dot backlight liquid crystal display has good development prospect.
At present, the most widely applied direct type backlight of quantum dots has the working principle that blue backlight and a quantum dot film are converted into white backlight with a high color gamut, and due to the limitation of a backlight structure, the quantum dot film cannot completely shield the blue light, and certain blue light leakage exists at the edge of a MINI LED panel, so that the final color purity of a picture displayed around a liquid crystal screen is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a direct-type MINI-LED quantum backlight module for preventing blue light side leakage, aiming at the defects of the prior art, and the problem of blue light side leakage of a MINI-LED board is solved by arranging white light MINI-LEDs around the blue light MINI-LEDs.
In order to solve the technical problems, the utility model adopts the technical scheme that:
a direct type MINI-LED quantum backlight module for preventing blue light from leaking laterally comprises a MINI-LED board and a quantum film covered on the MINI-LED board; the MINI-LED board is a quadrangle formed by blue light MINI-LED and white light MINI-LED in matrix arrangement; the blue light MINI-LED is arranged in the middle of the MINI-LED board in a quadrilateral manner; the white light MINI-LEDs are distributed on the periphery of the blue light MINI-LEDs in one or more rows; and a quantum coating region is distributed in the middle of the quantum film and covers the blue MINI-LED.
As a further preferred embodiment of the present invention, the quantum coating region is the same as the region of the blue MINI-LED on the MINI-LED board, and the quantum film non-quantum-coating region is the same as the region of the MINI-LED board.
The utility model has the following beneficial effects:
according to the direct type MINI-LED quantum backlight module capable of preventing blue light from leaking laterally, the white light MINI-LEDs are distributed around the blue light MINI-LEDs, when the blue light MINI-LEDs emit blue light, the white light MINI-LEDs also emit white light, the blue light overflowing and leaking from the edges of the blue light MINI-LEDs is inhibited through the white light MINI-LEDs, and the problem of light leakage of the edges of the direct type MINI-LED boards is solved.
