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.

At present, the touch technologies applied to products mainly include infrared, resistive, capacitive, surface acoustic wave, optical image, image recognition, panel induction, electromagnetic, light spot, and ultrasonic. The following is an analysis of the advantages and disadvantages of various touch technologies.

Conventional 5 inch display screens cannot be seen clearly under strong outdoor sunlight unless they have a brightness of 2000 lumens. To achieve this brightness, the number of high-brightness LED lights needs to be increased, which will increase power consumption and reduce battery life. Our company has successfully mass-produced a semi-transparent and semi-reflective 5 inch screen with a resolution of 800*480 and an RGB interface. It can display clearly in the sun without turning on the LED light, which reduces the power consumption of the machine and is the first choice for many outdoor electronic devices.

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.
