Abstract

A hinged LCD with increased rotation angle is composed of a base, a rotary unit installed to said base in rotary mode between the first and the second positions, and a liquid crystal panel connected to said base in rotary mode. Since the liquid crystal panel can rotate ninety degrees relative to the base, the liquid crystal display can be installed on the wall without detaching the base plate.

Description

Hinged LCD display with increased swivel angle

The utility model relates to a liquid crystal display, in particular to a hinged liquid crystal display capable of increasing the rotation angle.

Personal computers have become a necessity in daily life, and with the advancement of material technology and consumer preference, thin, light and small liquid crystal displays are increasingly replacing traditional CRT screens.

Since the liquid crystal display is light, thin and short, it can not only be placed on the table, but also has the function of hanging on the wall.

Fig. 1 shows an existing liquid crystal display 10, and it comprises a liquid crystal panel 11 and a base 12, and liquid crystal display 10 is placed on the table 20 by means of base 12; The base 12 is separated from the liquid crystal panel 11, and then an unshown wall-mounted assembly member is arranged on the back of the liquid crystal panel 11, and finally the liquid crystal display 10 after the base 12 is removed can be installed on the wall. The operation of separating the base 12 from the liquid crystal panel 11 is very cumbersome for the user, and the parts are often lost and damaged during the disassembly process, adding to the troubles of the user.
