Problems solved by technology

[0004] However, studies have shown that as this spacing is reduced, there is a corresponding increase in light utilization
When this spacing is 0.4, the light utilization rate is only 65%, and the light is not fully utilized

Abstract

The invention discloses a liquid crystal display device. The light incident surface of the light guide plate body is provided with protruding parts. When the light guide plate and LED lamp beads are assembled, a single row of LED lamp beads is arranged on two adjacent protruding parts. Between, the top surface of the protruding part can bear against the PCB board used to install the LED lamp bead. According to the relative relationship between the height of the protruding part and the height of the LED lamp bead, it can be accurately controlled to be sandwiched between two adjacent protruding parts. The distance between the light incident surface between the parts and the corresponding LED lamp beads, the distribution of bright areas and dark areas can be improved by setting dots on the protruding parts, thereby greatly improving the light utilization rate, making the liquid crystal display device The picture is more beautiful.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a liquid crystal display device. Background technique [0002] The backlight module is the component that provides the backlight of the LED liquid crystal display. The light source of the backlight module is divided into plane light source and line light source. As a point light source, arranging multiple LEDs in a single row can be regarded as a line light source. Assemble the line light source on one side of the LCD display, and use a light guide plate and a reflector to change the line light source into a relatively uniform light source through refraction and reflection. surface light source. [0003] The light incident surface of a typical light guide plate is flat. When the light guide plate is assembled with LEDs, a sufficient distance needs to be reserved between the light incident surface of the light guide plate and the LED lamp beads. The current distance...
