Smart, for the future trend, billion light sensor: make mobile devices from passive to active

In recent years, with the "IOT Internet of Things", "robot", "wisdom wear", "smart home" and "smart car" topics, various sensing solutions have been produced one after another. The use of light sensors is extremely extensive and often surrounds us. Around the life, many light sensors are used to sense the change of the light source, and then the conversion of the instructions is automatically performed on the application, and the optimal color temperature and brightness are achieved to achieve the best balance. Take the smart phone that modern people take as an example. When answering the phone, the face is close to the phone to turn off the screen, and the screen brightness adjustment when indoor or outdoor use will require the use of a light sensor. In particular, the power consumption of the screen accounts for about the mobile phone/ About half of the total power consumption of the wearable device, if you use the ambient light sensor, you can save more than 30% of the power, greatly increase the battery life, extend the time required for charging, and avoid looking for a charging socket or carrying a mobile power source when going out. Waiting for trouble.

 

As a leading LED industry in Taiwan, Yiguang has a complete and diverse range of optical sensor products with professional optical technology and rich optical packaging ODM and OEM experience. Ambient Light Sensor (hereinafter referred to as ALS) ALS-PDIC17-79NB/ The TR8 has a brightness resolution of 15bits. It can be adjusted to the optimum brightness by the ALS automatic feedback system, whether it is very bright outdoors or at night, to avoid the screen brightness and eye damage. It's easier and more comfortable. Ambient Light and Proximity Module (APM) The APM-16D18-00-DF8/TR8 incorporates proximity sensing (PS) for ALS 16 bit / PS in addition to ALS. The high resolution of 16 bit is very suitable for use on smart phones. Traditional mobile phones that are not equipped with PS often have accidental touches when answering calls. For example, after the built-in PS, when the user's face is close to the screen, The PS will automatically turn off the touch function and display to improve convenience. The color sensor (hereinafter referred to as CLS) is a higher-order ALS. It not only senses the intensity of light alone, but also senses the intensity of red, blue and green light, and automatically adjusts the backlight of the screen. The best color temperature and brightness, reducing the eye's eye irritation, to achieve the best balance, the same 16bit high-resolution specifications, especially suitable for high-quality applications such as screen color display and intelligent lighting. The above ALS, APM, and CLS are all packaged in a small size, so that the sensing function can simultaneously achieve light and thin features.

 

In the future, Everlight still adheres to the concept of growing together with customers, providing FAE to assist in the introduction of product services, discussing and developing new sensor products, meeting more applications and providing the most competitive products.
