What is true color? What is pseudo color? Give a professional definition

16 bit color can also use pseudocolor, but the main reasons for pseudocolor are that the screen performance is not bright enough, the brightness is not very uniform, and the pseudocolor screen reacts slowly, and there will be smear in action movies with a certain intensity.

Distinguish between true color and false color As long as you move the mouse with the fastest speed, the drag is false color.

Plus: Look at this model. Generally, those with "T" are true colors, and those with "S" are pseudo color.

The principle of liquid crystal display of color screen mobile phone is to put the liquid crystal between two conductive glasses through two electrodes.

The electric field effect of twisted nematic liquid crystal molecules is caused by indirect electric field driving to control the projection or shielding function of light source and power supply.

When it is turned on and off, light and shade are generated to display images, and color filters are added to display color images.

At present, the materials of mobile phone color screen mainly include:

Super twisted nematic screen

STE is more energy-saving and cheaper, but when STN waves move images, there will be residual images, which will affect painting.

Quality, color and brightness are worse than TFT.

CSTN color station

The brightness of CSTN is higher than that of STN, but the power saving is a little worse than that of STN. At present, many low-priced color screen mobile phones are used in the market.

CSTN screen.

DSTN double deck station

DSTN (Double Layer STN) solves the drift problem in traditional STN display, and the display effect is much better than STN.

Improve.

UFB ultra-fine & bright screen

In view of the shortcomings of CSTN, Samsung made technical improvements and introduced UFB screen, which improved the penetration of the whole screen.

Rate, make the backlight look brighter, improve the performance of color, but still can't achieve the effect of TFT.

TFT thin film transistor screen

Each liquid crystal pixel is driven by a thin film transistor behind the pixel, which can realize high speed, high brightness,

High contrast display of screen information, its effect is close to CRT display, but its disadvantage is that it consumes a lot of electricity and its cost is higher than CRT display.

Higher.

Thin film diode screen

TFD technology is jointly developed by Seiko and Epson, and is specially used on mobile phone screens. Is the folding of TFT and STN.

Compared with STN brightness and color saturation, it also saves electricity than TFT.

Organic light emitting diode organic light emitting display screen:

Organic light-emitting diode display technology can display vivid static images and smooth dynamic images without backlight.

The display screen is thinner, lighter, clearer, brighter in color, wider in viewing angle, and more energy-saving, reaching a near-perfect state.

Generally speaking, in terms of color performance, organic light emitting diodes > TFT > TFD > UFB > DSTN > CSTN > STN.

Because the image displayed by STN material is untrue, it is generally called "pseudo color" or "pseudo color".

",and TFT has the reputation of" true color "because of its vivid and true image display.

Ordinary "pseudo-color" mobile phones on the market do not indicate what screen it is, but use high brightness and high definition.

When buying a screen, ask what material it is, but don't spend the money of "real color" on "fake color"

"mobile phone!
