Description

The LCD holder

Technical field

The utility model relates to a kind of LCD holder.

Background technology

LCD has progressively replaced traditional fluorescence display owing to have advantages such as light weight, body are thin, radiationless.Present LCD is mostly combined by a liquid crystal panel and a holder, and holder comprises a underframe and the bracing frame that is fixed on the underframe, is articulated with reversing frame on the bracing frame, and liquid crystal panel just is fixed on the reversing frame.In order to ensure the stability of LCD, the width of underframe is several times of liquid crystal panel normally, so that the user is when adjusting the visual angle of liquid crystal panel, unlikelyly topples over and turn on one's side because of crank causes, and then damage expensive liquid crystal panel.

The holder of existing LCD mainly contains following main shortcoming:

1. because existing underframe mostly is highly lower base plate, observe comparatively comfortable height in order to allow liquid crystal panel be installed in the user, the bracing frame of holder is generally higher, so just relative cost of idleness.

2. the size owing to underframe is bigger, and bracing frame and underframe vertical fixing, also is articulated with reversing frame on the bracing frame, and the packaging volume of holder is huge, freight charges increase sharply, and shipped quantity is dwindled relatively so cause.

3. holder can change the angle of liquid crystal panel to the user when carrying out height control, therefore when adjusting the liquid crystal panel height, need carry out angular setting, and the user just bothers in use very much like this.

Summary of the invention
