Light sensor - leading the new trend of LCD screen

Photo Sensor - With the rapid increase in the use of mobile phones and LCD TVs, how to reduce the power consumption of LCD displays and improve image quality has become a challenge that related industries must overcome. Especially at night, when the screen is too bright it can cause eye fatigue, or in dark rooms where black halos appear on the screen. Therefore, currently in products equipped with LCD panels and powered by batteries, more and more are adopting illuminance sensors to measure ambient brightness and adjust backlight brightness accordingly. In the Japanese market, nearly 50% of models and around 60% of products in the European market are equipped with illuminance sensors. In recent years, advancements in photo sensor device technology have made it possible to effectively solve the aforementioned problems using illuminance sensors with spectral characteristics close to human visual sensitivity. According to industry statistics, the global potential market for photo sensors exceeds 1 billion units, among which the annual demand for mobile phones reaches as high as 600 million units, making it the current main market. It is predicted that the shipment volume of LCD TVs in 2008 will exceed 30 million units, and automotive instruments, displays, and lighting fixtures are all applicable objects for photo sensors.
