As long as you know the basic performance parameters and properties of LCD board, and then choose the brand with high reputation and good quality.
As long as you know the basic performance parameters and properties of LCD board, you can choose the brand with high reputation and good quality.
it is right to choose the right one.

What brand of LCD is good?

of course, Samsung, Philips and Sony's displays are better.
as for Uber, it takes Philips as the OEM original sheet manufacturer, that is to say, Uber only works in the sales channel market, and all its displays are Philips boards, It also belongs to A-class board.
some other brands, especially miscellaneous displays, should be carefully selected.
.
in addition, I think Mingji's performance is still average.
it's a brand with low cost performance among domestic brands.
the appearance is slightly good If you improve the performance a little bit, you will be overcharged.
while the cheaper ones are out of date.
.
you'd better choose a shape you like first.
and then look at the performance decision.
.
let's see about liquid crystal.
the dot distance and the dot distance of the visual area liquid crystal display refer to the space between each pixel that makes up the liquid crystal display.
At present, the standard dot pitch of mainstream 15 inch LCD products is generally 0.297mm, and the corresponding resolution is 1024 × 768.
.
.
the visible area of LCD is "real.
generally, there is such a reference: the visible area of 15 inch LCD is close to that of 17 inch CRT.
.
.
the most common screen defect is white spot or black spot.
the identification method of black spot is to turn the whole screen into white screen.
then there is no place to hide the black spot; The white dot is just the opposite. If the screen is turned to black, the white dot will show its original shape.
when the screen is turned to black, the white dot will show its original shapeGenerally, displays with no more than 3 defects can be considered as qualified products.
but the price is quite different from those without defects.
therefore, when choosing LCD, users must pay attention to select products without defects.
if there are no white spots or black spots.
only large brands with guaranteed quality can be selected.
.
.
brightness display brightness is generally CD The higher the brightness, the stronger the anti-interference ability of the display to the surrounding environment, and the brighter the display effect.
this parameter should be at least 200cd / m2.
it is better to be above 250cd / m2.
.
.
the higher the brightness of CRT is.
its radiation is greater, and the brightness of LCD is obtained through the backlight of fluorescent tube, Therefore, there is no negative effect on human body.
.
.
contrast refers to the ratio of brightness between bright area and dark area of the display under specified lighting conditions and observation conditions.
contrast is a parameter that directly reflects whether the LCD can reflect rich color levels.
the higher the contrast is, the higher the contrast is, At present, the nominal value of LCD is 250:1 or 300:1.
for high-end products, 400:1 or 500:1.
.
.
it should be noted that the contrast must be matched with brightness to produce the best display effect.
.
.
.
viewing angle LCD belongs to backlight display device.
the light emitted by it is generated by the light behind the LCD module The backlight provides, which inevitably leads to the LCD display has only one best viewing angle - face upWhen you look at it from other angles.
because the backlight can penetrate the adjacent pixels and enter the human eye, it will cause color distortion, The range of non distortion is the viewing angle of LCD.
the viewing angle of LCD can also be divided into horizontal viewing angle and vertical viewing angle.
the horizontal viewing angle is generally larger than the vertical viewing angle.
at present.
as long as the horizontal viewing angle reaches 120 degrees, it can meet the application requirements of most users.
.
.
.
response time refers to the response time of LCD for input signal Generally speaking, it can be divided into two parts: tr (rise time) and TF (fall time).
the response time refers to the sum of the two. The smaller the response time, the better, if it is more than 40 ms, At present, the standard response time of liquid crystal display is about 14 Ms.
however, there are a few models that can achieve 6 ms.
