The typical resolution of a 2.8-inch LCD screen is 240*320 or 240*400. Because its size is larger than a 2.4-inch LCD screen, but the resolution is the same, the larger area results in less detailed display, which is why many hardware engineers don't like using it. Shenzhen Hongjia Technology engineers recommend a 2.8-inch TFT screen with IPS full viewing angle and a resolution of 480*640, offering high-definition and fine detail, compensating for the low resolution of typical 2.8-inch screens. This article will also introduce the advantages of this display and the significant changes it brings.

Some customers are still not very clear about the resolution of the display screen. We will explain it here. The resolution of the LCD screen refers to the number of pixels of the LCD screen, that is, the number of dot matrix, which is usually the number of pixels in the horizontal direction multiplied by the number of pixels in the vertical direction. Under the same LCD screen size, the higher the resolution dot matrix, the clearer and more delicate the display image effect is.

Backlighting is used in small, light, flat-panel liquid crystal displays (LCDs) and other electronic devices that require backlighting, including handheld devices as small as the palm of your hand, and large-screen TVs. The goals of backlight design include low power consumption, ultra-thin, high brightness, uniform brightness, large area, and control of different width and narrow viewing angles. To achieve these challenging design goals with controlled cost and rapid implementation, computer-aided optical design tools must be used for design. This article introduces the characteristics of LightTools optical design and analysis software from ORA Company in the United States, which can be used to develop the most advanced backlight design applications today.
