1. The viewable area of ​​the LCD screenis a part of the display area that can be used to display images in practical applications. The whole size is actually the size of its frame and PCB board. The part that can be used to display the image simply does not reach this size, because the frame takes up some space. Generally speaking, the display area of ​​a 5.7-inch 320240 LCD screen is 122*92mm, while the display area of ​​a 5-inch 240128 LCD screen is 114*64mm. But for mobile phone LCD monitors, the nominal size is basically the size of the visible area, and the bezel takes up relatively little space. 5.7 320240 LCD screen area 122*92mm. So when choosing an LCD screen, please choose the LCD screen that suits your device. 2. Response rate Response speed is in milliseconds (MS), and milliseconds refers to the time required for a pixel to go from bright to dark and from dark to bright. The smaller the value, the better. The smaller the value, the faster the response. At present, the response speed of mainstream liquid crystal displays is above 1-2ms, which is not relevant in general industrial applications. 3. Resolution Resolution is a very important performance index. The number of dots that can be displayed horizontally and vertically on the screen (lines and areas displayed on the screen are made up of dots). The higher the resolution, the more information can be contained on the same screen. Both 320*240 resolution and 240*128 resolution can be displayed well. Because there is not much difference between the two, but a large resolution may not be the right resolution. If you use the content in the 320*240 LCD screen on the 240*128 LCD screen, the displayed content will be reduced. 4. Screen color When it comes to color, there are generally three colors: white characters on a blue background/black characters on a white background/black characters on a yellow background. Customers can choose different mobile phone LCD screen colors according to different devices.
