Frame-free liquid crystal display device

Abstract

A frameless liquid crystal display device comprising: a rear housing (2), a backlight module (4) arranged in the rear housing (2), a plastic frame (6) arranged on the backlight module (4) and fixedly connected to the rear housing (2), and a liquid crystal display panel (8) arranged on the plastic frame (6). The liquid crystal display panel (8) is connected at the upper end thereof to the plastic frame (6) via a connecting part (3). The connecting part (3) comprises an elongated strip-shaped base panel (32) and an elongated strip-shaped protruding structure (34) arranged on the elongated strip-shaped base panel (32). The plastic frame (6) is provided with a corresponding groove (66) at a position corresponding to the connecting part (3). The elongated strip-shaped protruding structure (34) of the connecting part (3) is accommodated in the groove (66) and lockingly fixes the connecting part (3) and the plastic frame (6) onto the rear housing (2) via a screw. The liquid crystal display panel (8) comprises a CF substrate (82) and a TFT substrate (84) affixedly arranged with the CF substrate (82). A stepped position (824) is arranged at the lower side of the CF substrate (82) and of the TFT substrate (84). A surface decoration material (9) is pressed at the stepped position (824) and is fixed onto the plastic frame (6), thus assembling the liquid crystal display panel (8) onto the plastic frame (6).

Description

technical field [0001] The invention relates to a display device, in particular to a frameless liquid crystal display device. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates, and control the liquid crystal molecules to change direction through whether the glass substrates are energized or not, and refract the light from the backlight module to produce a picture. [0003] The liquid crystal display device generally includes: a rear shell, a front shell cooperating with the rear shell, a backlight module set in the back shell, a plas...

Problems solved by technology

[0007] In order to securely fix the liquid crystal display panel 700 on the plastic frame 500, the adhesiveness of the double-sided adhesive 900 needs to be strong enough. However, this results in that the double-sided adhesive 900 is difficult to remove when the liquid crystal display panel 700 is disassembled, which may damage the liquid crystal display. Panel 700, causing huge damage which in turn increases repair costs
