Technical parameters are an important standard to measure the performance of the display. Due to different principles, the technical parameters of LCD displays are also very different. Next, let's take a look at the technical parameters of LC
Here is the content list:
Size
Dot pitch
Viewing angle
Brightness
Response time
Display color
Resolution
Exterior
The size of the display is the length of the diagonal line of the display screen, and its unit is inches, 1 inch = 2.539 cm, the main size the markets 15 inches, and the price mainly depends on the size.
Dot pitch refers to the distance between two phosphor dots on the dot pitch, the better the display effect. Now, the dot pitches on the market are generally 28, 26, and 25. The size and a t pitch of the LCD display will affect the resolution. As long resolution is used, the length of the display screen divided by the dot pitch can be calculated.
LCD display viewing angle is small, so this indicator is very important. The so-called "viewing angle" refers to the maximum angle that the screen image can still be seen when standing at a certain angle from the normal line of the screen; the larger the viewing angle, the better. Usually, the viewing angle of an LCD display is symmetrical from left to right, but not up and down. Moreover, the up-down angle is often smaller than the left-right angle. Since everyone's vision is different; therefore we rely on contrast. The greater the contrast measured at the maximum viewing angle, the better. Generally speaking, there are two standards in the industry, CR10, and5.
The acceptable brightness of a splay is more than 150cd/square meter, and the brightness of an LCD display that can be seen in China is basically about 200cd/square meter. The brightness of the LCD display is slightly lower, and it will feel dark; if it is slightly brighter, it will be much better.
The response time is as small as possible, it is the speed of each pixel of the LCD display spending to the input signal, that is, the speed of the pixel from dark to bright or bright to dark. The shorter the response time is, the less trail drag the user will feel when watching moving pictures. Generally, the reaction rate is divided into two parts: Rising and Falling, and the two shall prevail when expressed. Generally, bout 20ms is better.
Almost all 15-inch LCDs can only display high color, so many manufacturers use the so-called FRC. technology to simulate a full-color display. Of course, this full-color screen must also rely on the video memory of the display card, not the display card can support 16 × 106 full-color, so that the LCD display can display full-color.
LCD display resolution is usually represented by a product, such as 800×600, 1024×768, 1280×1024, etc., which represents the product of the number of pixels in the horizontal direction and the number of pixels in the vertical direction, and the pixel is the basic unit of the diagram, that is, the higher the pixels, the finer and more refined the image.
The LCD display has a slender body, and the thickness of the display panel is usually between 6.5 and 8cm. The shape is full of modernity. With black or standard pure white, it looks quite comfortable. Some LCD monitors can now be hung on the wall to fully demonstrate their portability.
