China 5.5 inch IPS High Brightness screen Manufacturers, Suppliers, Factory

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.

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.

Overheating of the LCD screen may accelerate component aging (such as shortening the screen lifespan). In severe cases, it may cause deformation of the plastic casing, damage to the circuit insulation, and even risk fire. If abnormal overheating cannot be alleviated by the above methods, it is recommended to immediately discontinue use and send the device for repair.

To avoid the problem of yellowing of the backlight material of the TFT LCD screen, it is necessary to start from many aspects such as material characteristics, usage environment, and driving method. In particular, it is necessary to pay attention to the selection and maintenance of the core components of the backlight module (such as LED lamp beads, light guide plates, diffusion films, etc.).

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.
