What are the main technical indicators of LCD monitors not included?

The main technical indicators of LCD monitors do not include storage capacity. The main technical indicators of the LCD display include: 1. Resolution, which refers to the number of dots displayed in the horizontal and vertical directions of the screen; 2. Dot pitch, which refers to the distance between two phosphors with similar colors in the same pixel; 3. Refresh frequency, Refers to the screen refresh speed; 4. Brightness and contrast; 5. The size of the picture tube.

The main technical indicators of LCD include display resolution, display speed, brightness, contrast, pixels, dot pitch, etc., but do not include storage capacity.

The main technical indicators of the monitor are:

1. Resolution

Resolution refers to the number of points displayed in the horizontal and vertical directions of the screen. For example: 1024x768, 1280x1024, etc. The "1024" in 1024x768 refers to the number of dots in the horizontal direction of the screen, and "768" refers to the number of dots in the vertical direction of the screen. The higher the resolution, the clearer the image.

2. Dot pitch

The dot pitch is the distance between two phosphors with similar colors in the same pixel. The smaller the dot pitch, the more delicate the displayed image, and the higher the cost. A few years ago, most monitors had a dot pitch of 0.31mm and 0.39mm. Now most of them have a dot pitch of at least 0.28mm. Now some high-end monitors have a dot pitch of 0.25mm or even smaller.

3. Refresh frequency

The refresh frequency is the speed at which the screen refreshes. The lower the refresh frequency, the more severe the image flicker and jitter, and the faster the eye fatigue. Generally, a refresh rate of 75Hz or above is used. frequency can basically eliminate flickering.

Therefore, a refresh frequency of 75Hz should be the minimum requirement for the stable operation of the monitor. In addition, another common display performance parameter is the horizontal scanning frequency, which refers to the number of horizontal points scanned by the electron gun on the screen, in KHz.

4. Brightness and Contrast

The meaning of maximum brightness is the maximum brightness of the white block when the screen displays white graphics. The unit of its value is cd/m2. Generally, it is white when the background is dark. The brightness above 70cd/m2 is satisfactory.

The meaning of contrast is the ratio of the brightness of the displayed image or characters (white blocks are used for testing) to the background color of the screen. The greater the contrast, the clearer the displayed characters or images.

5. Size

The screen size of the monitor actually refers to the size of the picture tube, but what you actually use is far from this size. The reason is that the frame of the picture tube takes up part of the space.
