Working in the office, eating out and shopping, returning home, display products are everywhere. We have entered the display era, and display products are used everywhere. Computers, TV sets, mobile phones, advertising machines, POS machines... Many of these display products use LCD screens. So how do we choose the LCD screen?

1. Size
Size is a very important factor in panel selection. The size of the LCD screen generally refers to the diagonal size of the LCD screen. So how can you know the size of the panel by looking at the model of the panel factory?

Take a 15.6-screen display from Chimei (Innolux), a Taiwan-based panel manufacturer, as an example. N156B6-L0B is a panel manufacturer's model, of which 156 represents a 15.6-inch LCD display. The LCD screen model of the general panel factory is not on the casing of the monitor, but on the label on the back of the LCD screen.

2. Resolution
Resolution is also a very important parameter. Resolution refers to the number of pixels that can be displayed on the screen. Commonly used resolutions for notebook panels are 1366*768, 1920*1080, 1024*600, 1600*900, 1280*800, etc. In the case of the same panel size, the higher the resolution, the more pixels that can be displayed, and the better the display effect. So how do you see the resolution of the panel factory's model? Generally, each panel factory's panel model has a specific letter combination to represent the resolution, such as Chi Mei (Innolux)'s N156B6-L0B, the B behind the size represents the resolution. The resolution is 1366*768. Innolux's N173FGE-L23, F means the resolution is 1600*900

3. Classification
At present, according to the different backlight sources on the market, liquid crystal panels are divided into LCD screens and LED screens. In fact, the LCD screen is a traditional liquid crystal panel with CCFL (cold cathode fluorescent lamp) as the backlight source, and the LED screen is a liquid crystal panel with light-emitting diodes as the backlight source. LCD screens are now used less often and are gradually being replaced by LED LCD screens. N156B6-L0B is LED screen.

Fourth, the signal interface
The signal interface parameter of the notebook panel is a very important parameter in the panel parameters. Generally speaking, the LVDS interface and the EDP interface are the most commonly used interfaces in the notebook panel. The LVDS signal interface has 30 pins and 40 pins, and the EDP signal interface also has 30 pins. and 40 pins. In addition, interfaces such as MIPI and TTL are also widely used in LCD panels. Innolux's notebook screen N156B6-L0B belongs to the LVDS interface, where L refers to the LVDS interface type.
Five, contrast, brightness, color gamut
The parameters of contrast, brightness, and color gamut are used to measure the display effect of the display screen. Display products for outdoor applications require high brightness and contrast. Contrast is the ratio of white to black displayed on a display, and it reflects the vividness of the colors presented. Color gamut refers to the method of encoding a color, and also refers to the sum of the colors that a technical system can produce. Current LCD screens have a much wider color gamut than previous CRTs.
6. Response time
The response time of the display screen is also the response speed (response time). Generally, gaming notebooks have extremely high requirements on response time. The shorter the response time, the less smear will occur when watching dynamic pictures. The response speed of the N156B6-L0B screen is 3/8 milliseconds, which is within the normal range.
Seven, the viewing angle
When viewing the screen from different angles, the display effect of the screen is different because the LCD panel has a viewing angle range. The angle of the general display screen is 45/45/20/45 (left and right up and down), and the viewing angle of the current IPS screen on the market reaches 89/89/89/89 (left and right up and down), which can be said to be quite wide. .
