Backlight module and liquid crystal display containing the backlight module

Abstract

The invention discloses a negative phototropism module and a relative liquid crystal display, which uses a thermal conductive structure to avoid non-uniform picture, wherein the negative phototropism module at least comprises a frame, a reflector plate, a thermal conductive plate, and a circuit board, the frame has a bottom with at least one step through hole, the reflector plate is on the inner surface of the bottom of the frame, the thermal conductive plate is in the step through hole, in preset distance from the reflector plate, the circuit board is on the outer surface of the bottom of the frame, with at least one electric element in the step through hole.

Description

technical field [0001] The invention relates to a backlight module and a liquid crystal display using the backlight module, in particular to a backlight module and a liquid crystal display with a heat conduction structure capable of eliminating uneven display images. Background technique [0002] Integrated circuits (ICs) usually generate high heat during data processing, so how to enhance heat dissipation design to increase heat dissipation performance has always been a very important part of electronic module design, especially in the field of displays. As the display speed of data is increasing day by day, and due to volume limitations (especially in the field of notebook computers), the distance between the electronic components and the optical components in the LCD module is quite close, so the high heat emitted by the electronic components will locally affect the backlight module Optical performance of optical film, light guide plate or array / unit (Array / Cell) liquid c...

Problems solved by technology

However, as a result of directly attaching the heat conduction sheet, because the thermal expansion coefficient of the heat conduction sheet is different from that of the reflector, it will cause local unevenness of the display screen, and there will be traces on the edge of the heat conduction sheet, which will cause obvious bright lines on the screen.
