Description

Liquid crystal display screen originally presses device

Technical Field

The invention relates to the field of liquid crystal display screens, in particular to a liquid crystal display screen local pressure device.

Background

A Liquid crystal display, LCD (Liquid CRYSTAL DISPLAY), is a flat, ultra-thin display device, which consists of a number of color or black and white pixels, placed in front of a light source or reflector.

The display principle of LCD is that liquid crystal material is filled between two parallel plates, and the arrangement state of molecules in the liquid crystal material is changed by voltage so as to attain the goal of shading light and transmitting light to display images with different depths and different heights. Currently, monochrome LCDs have been almost withdrawn from the notebook market, while color LCDs continue to develop. Color LCD is divided into STN and TFT, wherein TFT (Thin Film Transistor) LCD is also called active transistor LCD, which is called true color LCD by many people; DSTN (Dual-SCN TWISTED NEMATIC) LCD, a Dual scanning liquid crystal display, is one display mode of STN LCD, and has been taken out of the market.

The electric signal component of the liquid crystal display mainly comprises a backlight circuit and a display circuit, wherein the display circuit is used for transmitting charges and control signals required by the pixel driving of the liquid crystal panel, the charges and the control signals are mainly transmitted by using a printed circuit board PCB (Printed Circuit Board), and meanwhile, the charges and the control signals are transmitted into the liquid crystal panel through a driving IC (Driver IC). One end of the Driver IC is connected with the liquid crystal panel, and the other end is connected with the PCB. The two adjacent sides of the liquid crystal panel are divided into a Gate end and a Source end, driver ICs at the Gate end are connected to the Gate end of the liquid crystal panel and are responsible for switching on and off each row of transistors at a time, the Driver ICs at the Source end are connected to the Gate end of the liquid crystal panel, and when the transistors are switched on, the Driver ICs at the Source end can only control brightness, gray scale and color line by line to enter pixels of the liquid crystal panel through channels formed by the Source ends and the Drain ends of the transistors. Therefore, in the process of manufacturing the liquid crystal display, the liquid crystal panel, the Driver IC and the PCB are required to be pressed in sequence.

The pressing process is mainly divided into two processes, namely, prepressing and the present pressure, wherein the prepressing is the process before the present pressure. Pre-pressing, namely, punching conductive adhesive films on connection areas at two ends of the Driver IC, and then applying certain pressure to position the Driver IC on the conductive adhesive films; the Driver IC is fixedly connected with the PCB or the liquid crystal panel after a certain pressure is applied to the Driver IC which is positioned.

The existing present pressure device has the following problems:

1) Because the thicknesses of the Driver IC and the PCB are very thin, the uneven pressing pressure can be caused by a slight deviation of the parallelism between the plane of the pressing head and the pressing platform, so that the phenomena of falling off, glue opening and the like are easy to occur after the pressing;

2) The product to be pressed is difficult to be quickly and effectively taken down from the conveying guide rail, so that the pressing efficiency is low;

3) Lack of mechanism for heat insulation and lamination protection of the surface layer of Driver IC or PCB in the process of the present pressure, which is easy to burn or crush the surface of Driver IC or PCB in the process of the present pressure;

4) The Driver IC with different sizes cannot be adapted due to the limitation of the degree of freedom, so that the applicability of the suction mechanism is affected to a certain extent;

5) Aiming at different pressing requirements and Driver IC or PCB size models, the camera used for alignment often cannot or is inconvenient to make corresponding position adjustment, so that the camera cannot be focused accurately, and the accuracy of photographing and positioning is affected.

In view of the foregoing, it is necessary to develop a liquid crystal display screen driving device for solving the above-mentioned problems.
