4. Sharp Character Display
The picture is stable and does not flicker. The unique display principle of LCD determines that the pixels on its screen emit light evenly, and the red, green and blue three primary color pixels are arranged closely. Video signals are sent directly behind the pixels to drive the pixels to emit light. Therefore, the inherent convergence and poor focus of traditional CRT display will not occur. Therefore, the text display effect on LCD is different from traditional CRT display. LCD fonts are very sharp, there is no CRT display text when the font blurred, font pan-color and other phenomena. Moreover, because the LCD has been emitting light after power on, the backlight works at high frequencies, and the display screen is stable and does not flicker, which is conducive to the use of computers for a long time. CRT displays emit light by repeatedly impacting an electron beam on the phosphor, which results in periodic flashing of brightness. It is easy to cause eye discomfort after long time use.
5. Convenient screen adjustment
The direct addressing display mode of LCD makes the adjustment of LCD screen not need too much geometric adjustment, linear adjustment and position adjustment of display content. LCD can automatically adjust the screen to the best position by chip calculation. This step can be accomplished by pressing the "Auto" key. It eliminates the tedious adjustment of CRT display. You just need to manually adjust the brightness and contrast of the screen to make the machine work at its best.
