Abstract

Embodiments of the invention provide a backlight driving device and display equipment and relates to the display technology field. The backlight driving device is located on a back side of a first liquid crystal display screen. The device comprises a transmission unit and a first LED luminescence unit, wherein the transmission unit is used for carrying out periodic cycle movement along a transverse length or a vertical width of the first liquid crystal display screen; and the first LED luminescence unit is installed on the transmission unit and provides backlight for the first liquid crystal display screen when being moved along with the transmission unit. In the embodiments, the structure and a manufacturing technology are simple; and usage and manufacturing cost is low.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a backlight source driving device and a display device. Background technique [0002] The backlight is a light source located behind the LCD screen, and its luminous effect will directly affect the visual effect of the LCD screen. The traditional backlight needs to cover the entire screen with LED light-emitting units when working, which consumes a lot of materials. Such as figure 1 As shown, the traditional display module uses diffusers, prisms and light guide plates to prevent the loss of light from the backlight and to diffuse the light evenly. This kind of module device is complex, has high requirements for film materials, and the manufacturing process of the light guide plate is complicated, and the phenomenon of power consumption and heat generation is serious. [0003] Therefore, how to solve the defect of complex process and structure of the backlight dr...
