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.

Static electricity can be grounded in the early hardware design. In the later production, pay attention to wearing static bracelets and finger cots to avoid holding the display screen directly with your hands. Then, static electricity experiments can be performed to detect whether the static electricity of the entire machine meets the standards.

IGZO displays can be seen as Sharp’s specialty. Recently, Sharp’s smartphones launched in the Japanese market are all equipped with IGZO displays without exception. It is worth noting that the biggest highlight of Sharp mobile phones equipped with this screen is the "ultra-long standby". Of course, this is also the advantage of the IGZO display. Sharp AQUOSPHONEZETA, which has the longest standby time in the history of Japanese operator DoCoMo, has officially benefited from the low power consumption of the IGZO display.

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.
