Description

display device

technical field

The present invention mainly relates to a display device, especially a display device with an elastic fixing unit.

Background technique

Please refer to FIG. 1 , which is a schematic cross-sectional view of a known display device 1 . The display device 1 includes a panel module 11 , a side cover 12 , a combination unit 13 , a housing 14 , and a plurality of elastic protrusions 15 . The panel module 11 is fixed on the casing 14 via the side cover 12 and the combining unit 13 . The elastic protrusion 15 is disposed on the side cover 12 to prevent the panel module 11 from being bumped.

Most of the known panel modules 11 use the frame 112 to fix the backlight 111 and the liquid crystal panel 113. The frame 112 not only protrudes from the display surface S1 of the panel module 11, increases the thickness of the display device 1, but also increases the non-display of the display device 1. The width of the edge zone Z1. In addition, the known side cover 12 further increases the thickness of the display device 1 and the width of the non-display edge area Z1 in order to cover the frame body 112 and engage with the combination unit 13, which does not meet the current requirements for the display device 1. Lightweight requirements.

Furthermore, the material of the side cover 12 is mostly metal or hard plastic. Generally speaking, the side cover 12 made of the aforementioned materials may have errors, and a gap is formed between the side cover 12 and the display surface S1. Therefore, the light emitted by the backlight plate 111 below the side cover 12 will be emitted through the above-mentioned gap, resulting in light leakage from the side of the display device 1 , thereby reducing the display quality of the display screen.
