What are the standard aspect ratios?
Standard aspect ratios such as 4:3, 5:4, and 16:9 are commonly used in applications in industrial and consumer areas. These displays have a range of resolutions such as 800 x 600, 1024 x 768, 1280 x 1024, or full HD 1920 x 1080.
To simplify this, the larger the number of the screen resolution, the better. It does not really matter what physical size or display ratio the screen is, the best quality image comes with a higher resolution.
1. The resolution of the LCD display screen
LCD Display Screen Resolution is a very important performance indicator. It refers to the number of dots that can be displayed in the horizontal and vertical directions on the screen (lines and surfaces displayed on the screen are all composed of dots). The higher the resolution, the more information the same screen can hold inside.
Whether it is 320*240 resolution or 240*128 resolution, it can be better displayed. Because the difference between the two is not big, a large resolution may not be a suitable resolution. If the content in the 320*240 LCD display screen is used on the 240*128 LCD display screen, the displayed content will definitely be reduced.
2. The viewing area of the LCD display screen
It refers to the part of the display area that can be used to display images in practical applications. The full size is actually the size of its bezel and PCB board, and the part that can be used to display the image cannot reach this size at all, because the bezel takes up part of the space.
Generally speaking, the 5.7-inch 320240 LCD display screen has a display area of 122*92mm, while the 5-inch 240128 LCD display screen has a display area of 114*64mm. But for LCD, the nominal size is basically the size of the viewing area, and the space occupied by the frame is relatively small. The display area of 5.7 320240 LCD display screen is 122*92mm. Therefore, when purchasing an LCD display screen, choose the equipment that suits you.
3. The response speed of the LCD display screen
The time unit for measuring reaction speed in milliseconds (ms), refers to the time it takes for a pixel to change from light to dark and dark to light. The smaller the value, the better. The smaller the value, the faster the reaction speed. At present, the response speed of mainstream LCD is more than 1-2ms, which is not very relevant in general industrial use.
4. Colors of the LCD display screen
When it comes to colors, 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 display colors according to different devices.
