Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

Abstract

The invention discloses a controllable backlight structure and a display device using the same. The controllable backlight structure comprises a liquid crystal panel and a backlight source, wherein the backlight source provides a light source for the liquid crystal panel; a blind window unit is arranged between the liquid crystal panel and the backlight source; the blind window unit comprises a plurality of blades which are arranged in an array manner; each blade is connected with at least one rotating mechanism; the rotating mechanisms are connected with a control circuit; and each rotating mechanism rotates to open and close the corresponding blade, so that the backlight source is controlled to have different incident lights in different regions of the liquid crystal panel. The controllable backlight structure is simple and is easy to implement, while a liquid crystal image displaying effect is improved, the power consumption is low, and energy conservation is facilitated.

Description

technical field [0001] The invention relates to the technical field of liquid crystal backlights, in particular to a controllable backlight structure and a display device using the structure. Background technique [0002] With the development of LCD TVs, the quality requirements of LCD TVs are getting higher and higher. HDR (High-Dynamic Range), that is, high dynamic contrast technology, through the backlight partition control and the contrast improvement of the LCD screen, the contrast of the TV screen becomes higher and the picture quality is improved. [0003] The backlight partition control principle and structure of the existing liquid crystal display device are complicated, the power consumption is large, and the energy is not saved. [0004] Therefore, the prior art has yet to be developed. Contents of the invention [0005] In view of the shortcomings of the above-mentioned prior art, the purpose of the present invention is to propose a controllable backlight str...
