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.

​The primary part of an LCD display is an LCD panel, or liquid crystal display. It is a flat panel with two glass panels layered on top of small liquid crystal cells. The crystals align and alter the amount of light that passes through them when an electric current is applied, creating an image that can be seen.

With the advancement of technology, beauty devices have made great progress, especially the introduction of 3.97-inch IPS screens. 480*800 resolution, 1000 contrast, support for RGB and MIPI interfaces, high-definition and delicate full-viewing angle, high color saturation and many other advantages, and the compact size of these screens makes handheld devices easy to carry around, while IPS technology gives users a clearer viewing experience. In this article, we explore the various applications of this screen in beauty devices.

How MCU Drives LCD Screen and Design Considerations

Ordinary LCD screens use CCFL light sources, that is, cold-cathode fluorescent lamps (similar to the scanning lamps in the copy), with one on each side of the screen and a backlight on the back of the display, which is composed of fluorescent substances. The light sources on both sides can be evenly distributed on the back of the entire screen, so that the entire screen can be evenly illuminated. However, due to technical limitations, the brightness of such a display is not completely uniform, but it is difficult to find it. At the same time, the lamp also has a certain lifespan, and it will turn yellow after a long time.

After VGA, QVGA, WVGA, and HVGA resolution products were gradually born. These resolutions can be seen everywhere in the mobile phone parameters. The following is the explanation and difference of VGA, QVGA, WVGA, and HVGA.
