Description

Light leakage prevention structure of display

Technical Field

The utility model relates to a display technical field especially relates to leak protection light structure of display.

Background

The design of displays and television products is changing day by day, and the design of displays and televisions is mainstream due to low cost and simple operability. The traditional method for preventing light leakage is to paste a shading EVA (ethylene-vinyl acetate copolymer) on the inner side of the front panel of the display, only the position of a light outlet hole on the front panel of the display is left, and when an LED lamp irradiates on the front panel of the display, only the light outlet hole can emit light; the other method is to use shading EVA to wrap the LED lamp and reserve a small hole which can lead the light to be emitted to the direction of the light outlet hole of the front panel of the display; however, these methods have poor light leakage prevention effect and poor consistency.

The prior patent No. (CN 204883482U) proposes a light leakage prevention structure of a display and a display with a light leakage prevention device, the device is characterized in that a lampshade is sleeved at one end of a PCB (printed Circuit Board) key board through the design of the lampshade, and the LED lamp is shielded, so that the light of the LED lamp can only be emitted to a light guide column of a front panel of the display through a light outlet hole formed in the side surface of the lampshade, and during assembly, the lampshade is sleeved on the PCB key board and then is fixedly installed on a rear shell of the display, so that the light emitting position of each LED lamp is unique, no redundant light can be emitted to the front panel of the display, and the light leakage prevention effect is good; in addition, lamp shade unified manufacturing obviously has easy operation, characteristics that the uniformity is good, but its device has when front panel and rear panel are installed, has the condition that probably leads to junction deformation or light leak, to above-mentioned problem, this practicality provides the leak protection light structure of display.
