Liquid Crystal Related Problems summary

First, Color chapter

(color, brightness, contrast, angle, color temperature)

First special emphasis: for any display (crt/lcd/...). ), color is always the first! The authenticity and softness of color display is the most direct feeling to the eye!

As for the brightness contrast and even the perspective of why to fall to the color section, the following will have the answer.

"Good liquid crystal display color standard" rich and full of color, the appropriate brightness contrast, a broad perspective, flexible and reasonable color/brightness/contrast adjustment.

Q 1.1: Why two brands of LCD display the same picture, it looks different?

A 1.1: The LCD display effect by the Panel, control circuit and other aspects of the decision, different liquid crystal using a different parts and technology, the results will certainly have a difference. In fact, this difference in the CRT also exists, such as the Teflon and Dana Tube, but the LCD due to its own characteristics, in this respect the difference is larger than the CRT. This has become the most effective way to determine the quality of liquid crystals-the same screen, contrast effects, the feelings of their own eyes is the most persuasive standard.

Q 1.2: How many colors can the liquid crystal display? How much worse than the CRT?

A 1.2: Now the market, the strengths of the LCD can directly display about 167,000 colors (Note that not every one can show so much), and the CRT can display a number of colors is infinitely many. This is the deficiency of the liquid crystal, but the two principles are different. CRT by a few adjacent color points show a certain color, color point only red, green and blue three, mixed to give you "illusion", and LCD is each color point can display 167,000 kinds, give you direct color. So we can say that in fact LCD strong, CRT only three kinds of colors (psychological yy, hehe).

Q 1.2.1: Can you show colors beyond this range for a 167,000-color LCD?

A 1.2.1: For colors that cannot be directly displayed, the liquid crystal also has a processing method, such as alternating display of two colors to create a new color of the "illusion." In this respect, the technology of the vendors are not the same, there are no processing, so there will be colorful and rich degree of difference.

Q 1.3: What is the difference between 16-bit color, 24-bit color, 32-bit color?

A 1.3: In terms of color, of course, it is obvious that 2 of 16, 24 and 32 of the difference between the two sides. From the sense of the human eye, 16-bit color can basically meet the display needs, coarse looks and 24-bit color, 32-bit color similar, careful research, will find in large area of the gradient in 16-bit color display will appear vaguely divider line. In practical applications, the most commonly used is 24-bit color, such as Web pages and other places to represent the color of the "#80FF2E" such as strings, with ACDSee to see the picture can also see most of the picture's color depth is 24 bits. As for 32-bit color, which is added on the basis of 24, is said to be added 8-bit transparent color, the actual and 24-bit color is not much different, at least our eyes are not distinguishable.

Q 1.4: I am using LCD, Windows is not set to 16-bit color is enough?

A 1.4: Of course not! Or to set the 32-bit color! According to the above, the LCD direct display of the number of colors between 16 and 24, and another special technology to enrich the color. So the liquid crystal display set to 16-bit color is actually overqualified, especially for those excellent liquid crystal, is really a waste of the company's efforts. I give two pictures, the same one in 16-bit and 32-bit (in fact, 24-bit), and the difference is seen on the CRT set to 32-bit color. You use the LCD screen can be set to 32-bit display carefully distinguish, if you see the difference of two, that your LCD is still good; Illustrious, there is a problem.
