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.

​An LCD display module is an electronic component used for displaying characters, symbols, and graphics in a clear, easy-to-read format. It typically consists of a liquid crystal display (LCD) panel, a driver circuit board, and other supporting components, such as backlighting and a controller chip.

Usually, touchable LCD screens are capacitive screens, and the positioning method of the touch screen is through the electric field. Therefore, when static electricity and discharge occur, the LCD touch screen will have a "drift" screen effect, that is, the click position is offset from the actual response position.

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.

Shenzhen Hongjia Technology has successfully mass-produced the 4.45-inch TFT LCD screen, model HJ4450-01. This 4.45-inch horizontal screen LCD features IPS full viewing angle, 1920*1080 resolution, a MIPI interface, and a high refresh rate of 120Hz.

In the field of small-size TFT screen driver ICs, ST7796 and ILI9488 ICs are often used by customers. Many customers also have questions when choosing ICs. Which IC is more cost-effective and has better performance? Today I will briefly express my views here. If users are making devices that require high refresh rates, such as gaming devices or video playback, ST7796U may be more suitable. ILI9488 may have more advantages in cost or be more flexible in some interfaces.
