Rotation positioning module for display unit

Abstract

A display rotary positioning module comprises a first rotating device, a second rotating device, a positioning switch and an auxiliary positioning post, wherein the first rotating device is connected to a display through rotating motion, and is connected to a second rotating device for pivoting the second rotating device, the positioning switch and the auxiliary positioning post jump upwards at predetermined positions, the auxiliary positioning post also crosses through the rotating element of the second rotating device, thus fixing the rotating device at a predetermined position, and making the display can only rotate along the rotational direction of the first rotating device, when the positioning switch and an auxiliary positioning post are pressed, the display can rotate along the direction of the first rotating device and the second rotating deivce.

Description

technical field [0001] The invention relates to a rotation positioning module of a display, in particular to a rotation positioning module of a liquid crystal display of a notebook computer. Background technique [0002] With the advancement of optical technology and semiconductor technology, liquid crystal display devices (Liquid Crystal Display; LCD) have been widely used in display devices of electronic products. Liquid crystal displays have the advantages of high image quality, small size, light weight, low voltage drive, low power consumption and wide application range, so they have been widely used in portable TVs, mobile phones, video recorders, notebook computers, desktops, etc. In consumer electronics or computer products such as large-scale displays and projection TVs, it has become the mainstream of displays. [0003] Generally speaking, the liquid crystal display of the notebook computer is fixed in the top cover of the notebook computer. When using the noteboo...

[0005] However, because the screen has the function of being able to rotate left and right, it often causes the liquid crystal display screen to shake when it is in use, and instead causes the screen to be unstable when in use.

And because in order to make the screen have the ability to rotate left and right, a part of the rotatable screen forms a concave hole at the position of the rotation axis. When the screen is opened, you can see this concave hole, which is not only unsightly for the appearance design of the notebook computer , and if a foreign object falls into the cavity, it will make the screen unable to rotate, and even destroy the rotating mechanism
