The display resolution (screen resolution) of an embedded display is the precision of the screen image and refers to how many pixels the embedded display can display. Since the dots, lines, and areas on the screen are composed of pixels, the more pixels the embedded display can display, the finer the picture, and the more information can be displayed in the same screen area, so resolution is very important.
You can think of the whole image as a large chessboard, and the resolution is expressed by the number of intersections of all longitude and latitude lines. When the display resolution is fixed, the smaller the display screen of the embedded display, the clearer the image. On the contrary, when the display screen size is fixed, the higher the display resolution, the clearer the image.
Size and resolution also play a role in the overall readability of industrial displays. In general,10.4, 12.1 and 15 inches are mostly used in industrial applications. These dimensions provide enough space for viewing numbers, signal waveforms, or other graphical data without taking up too much space on the device. The requirements for resolution are mainly determined by the display information or display data.
In the past, VGA, SVGA, and XGA resolutions were the most popular. However, more and more manufacturers are beginning to pay attention to the profits of large aspect ratio embedded displays, such as WVGA and WXGA. Large aspect mode allows users to view longer information waveforms and more data on one display. These industrial displays can also be designed to incorporate touch key functionality on the display surface, allowing users to view data on large aspect ratio displays or switch between standard aspect ratio displays incorporating touch screen functionality. This new advanced functionality is extremely helpful to simplify the user interface.
