Frameless LCD Display Device

Abstract

A frameless liquid crystal display device, comprising: a rear housing (2), a backlight module (4) arranged within the rear housing (2), a plastic frame (6) arranged on the backlight module (4) and fixedly connected to the rear housing (2), a liquid crystal display panel (8) arranged on the plastic frame (6), and a surface decoration material (9) arranged at the lower end of the liquid crystal display panel (8). The liquid crystal display panel (8) comprises a CF substrate (82), a TFT substrate (84) affixedly arranged with the CF substrate (82), and, an upper polarizing film (86) and a lower polarizing film (88) respectively affixed onto the CF substrate (82) and onto the TFT substrate (84). The lower polarizing film (88) directly forms protruding parts (3) respectively on non-display areas at the upper and lower ends of the liquid crystal display panel (8). A corresponding engaging groove (66) is formed on the plastic frame (6). One end of the engaging groove (66) is open, while the other end is closed. The protruding part (3) is capable of being inserted into the engaging groove (66) via the open end, thus engagingly fixing the liquid crystal display panel (8) onto the plastic frame (6). The frameless liquid crystal display device has the lower polarizing film (88) of the liquid crystal display panel (8) formed directly on the protruding parts (3) that are engaged onto the plastic frame (6), and the liquid crystal display panel (8) is thus removably mounted onto the plastic frame (6), thus implementing the fixing of the liquid crystal display panel (8) of the frameless liquid crystal display device.

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 device (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,...

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
