Luminosity Adjustment for TV Screens, CRT Monitors and Liquid-crystal Display Monitors Notebook PCs and Portable Information Devices Cellular and PHS Phones Other Equipment Requiring Luminosity Adjustment
The TPS818 is a linear-output (current output type) photo-IC which incorporates a photodiode and a current amp circuit in a single chip. A luminous efficiency correction filter mounted on the detector ensures accurate luminosity output levels. The device’s excellent output linearity enables automatic adjustment of the luminosity of a TV screen or PC monitor in accordance with the ambient brightness of the operating environment.
