How to Make the Enclosure for an LCD Display Screen?

You know how the LCD display screen shell is made? When designing the shell, three aspects should be considered: the important dimensional parameters of the LCD display screen, the shell size design, and the shell assembly process. Today, we will introduce the production of LCD display screen shells.

The important dimensional data of the LCD display screen

Outer size - External size of the liquid crystal screen

Visible area (thin-film transistor open circuit) - Visible area of the liquid crystal screen

Active area, that is, the active area where the pixels are located

Set the shell size of the LCD display screen

If the window of the LCD display screen shell is larger than the visible area (TFTOPEN), the metal frame of the display screen will be exposed, which is very ugly. On the other hand, if the window is smaller than the effective area (TFTAA), we will cover the image displayed on the screen. Therefore, we should design the LCD liquid crystal screen shell from OD, OPEN, and AA.

The opening of the LCD display screen in the shell should be larger than the outer dimensions (OD) of the LCD screen on the drawing, because the display screen cannot be placed tightly on the shell, which will damage the FFC tape or display screen. An offset of about 2 millimeters may be appropriate.

When designing the shell of the LCD touch module, pay attention to the size of the glass (length, width, and corner radius), the touch panel, the thickness of the glass, and the mounting tape.

The diameter and spacing of the mounting holes are important parameters for the display module with a mounting frame.

When designing the shell of the LCD display monitors, all of the above dimensions should be considered.

Shell assembly process of LCD display screen

The correct assembly process of the liquid crystal screen module is very important. The common damage in the wrong assembly process is the loss of FFC.

The position of the throttle gate is separated from the transmission oil.

Damage to thin-film transistor glass.

Bending of the LCD display frame.

In the first stage of installing the display module in the shell of the LCD display screen, pay attention to protecting the edge of the FFC to ensure that the FFC is not damaged.
