The terminal application common Character LCD Module panel

Common liquid crystal display according to the physical structure is divided into four categories:Lcd display modules 
(1) twisted nematic (TN-TwistedNematic);
(2) super twisted nematic (STN-SuperTN);
(3) double super twisted nematic (DSTN DualScanTortuosityNomograph);
(4) The thin film transistor type (TFT-ThinFilmTransistor). \
The type 1.TN basic display in the liquid crystal display technology, after other types of liquid crystal display in TN type is based to be improved. Moreover, its principle of operation as compared to the other technologies to simple. Please refer to the image below. As represented in FIG is simple configuration diagram of a TN type liquid crystal display, including the vertical direction and the horizontal direction of the polarizing plate having fine lines trench alignment film, the liquid crystal material and a conductive glass substrate.
The display principle 2.STN is similar TN. The liquid crystal molecules of the TN twist nematic field effect type of the incident light is rotated by 90 degrees, STN super twist nematic field effect, the incident light is rotated 180 to 270 degrees.128x32 oled
3.DSTN dual scan to scan twisted nematic liquid crystal display, so as to achieve completion display purposes. The DSTN are developed from super twisted nematic display (STN). DSTN dual-scan technology, the display relative STN, has greatly improved.
More complex 4.TFT type liquid crystal display, mainly by: fluorescent tube, a light guide plate, a polarizing plate, filter plate, a glass substrate with a film, the liquid crystal material, a thin mode transistor. First, LCD monitors must use the backlight, which is projected light fluorescent tubes, these light sources will first go through a polarizer and then through the LCD. In this case, the arrangement of the liquid crystal molecules will change to penetrate the liquid crystal light angle, then the light must also pass in front of the color filter film and a polarizer. So as long as we change the voltage applied to the liquid crystal can control the last occurrence of the light intensity and color, so you can change the LCD panel with different shades of color combinations. Is the the mainstream liquid crystal display panel.
