Problems solved by technology

[0006] However, since light can travel freely in the light guide plate, and the light angle of ordinary LEDs is relatively large, when adjusting or closing a certain section of LED light string, the corresponding light guide plate area will still have light from other areas. , thus affecting the dimming effect in this area
[0007] Therefore, the existing technology still needs to be improved and developed

Embodiment Construction

[0022] The specific embodiments and examples of the present invention will be described in detail below in conjunction with the accompanying drawings. The described specific embodiments are only used to explain the present invention, and are not intended to limit the specific embodiments of the present invention.

[0023] Such as figure 1 as shown, figure 1 It is a schematic plan view of the first embodiment of the backlight module of the present invention. The backlight module includes a backplane 110 and LED lights 120. The LED lights 120 are correspondingly arranged on the left and right sides of the backplane 110. A light guide device 130 is disposed between the two LED lamps 120 for forming a local space on the back panel 110 that can be dimmed locally.

[0024] combine figure 2 as shown, figure 2 It is a schematic diagram of the structure of the light guide device in the backlight module of the present invention. The light guide device 130 can make the light emitted...

Abstract

The invention discloses a liquid crystal television and a laterally-inserted backlight module thereof. The backlight module comprises a back panel and LED lamps, the LED lamps are arranged on two sides of the back panel correspondingly, a light guiding device is arranged between two corresponding LED lamps and used for forming a local space on the back panel, and the local space can be subjected to local dimming by the light guiding devices. Since the light guiding devices capable of realizing local dimming are arranged among the laterally-inserted LED lamps, light emitted by the LED lamps can be mixed inside the light guiding devices uniformly, affection of adjacent areas from light leakage can be avoided, uniformity of light in a single area is improved and local dimming effect is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal televisions with a local dimming function, and more specifically, the improvement relates to a backlight module of a 3D liquid crystal television based on a side-lighting type without a light guide plate. Background technique [0002] In recent years, with the rapid development of software and hardware, China's domestic flat-panel TVs are also developing in the direction of 3D, and TVs with 3D image playback functions are gradually forming the development direction of flat-panel TVs. [0003] At the same time, with the introduction of the concept of energy saving and environmental protection, the technology of flat-panel TVs is also progressing in a more energy-saving direction. For example, local dimming technology (Local Dimming) is one of the best technologies that combines energy saving and image quality improvement. . [0004] The so-called LCD TV backlight area adjustment technology refers to ...
