FUKUDA CardiMAX FX-7202 ECG Machine LCD IF Board PCB-6871A

used good condition

►Quick Detail:

This product is FUKUDA CardiMAX FX-7202 ECG Machine LCD IF Board PCB-6871A, which is a small component used in the display screen of FUKUDA CardiMAX FX-7202 ECG Machine.
The FUKUDA CardiMAX FX-7202 ECG Machine has a touchable display screen, and the LCD IF Board PCB-6871A provides great assistance in the convenient display of the screen.

Red, green, and blue colors intersect on the LCD IF Board, from the creation of the light touch film, BM formation, RGB formation, to ITO formation, resulting in the display of every pixel on the screen.

• Pixel electrode: LCD display uses TFT to control the liquid crystal capacitor, thereby controlling the liquid crystal deflection of the corresponding pixel to obtain the color and image we want; the capacitor has positive and negative poles, and this is one of the electrodes of the liquid crystal capacitor; since the liquid crystal capacitor has one electrode on the TFT substrate, and the liquid crystal exists between the electrodes, the other electrode of the liquid crystal capacitor should exist on the CF substrate;

Most LCD use a bottom gate structure. Because the passive light-emitting devices of liquid crystal displays require a backlight source on the back of the display, the opaque gate metal layer in the bottom gate structure can effectively block the light from the backlight, avoiding the generation of charge carriers on the silicon island and affecting the off state current characteristics of thin film transistors.

The LCD IF Board dissolves the exposed portion of the photoresist in the (positive) photoresist into the fast developing solution (negative photoresist, on the contrary, dissolves the unexposed portion in the developing solution), while the unexposed portion dissolves slowly. By controlling the development time, the pattern on the photomask can be displayed
