This document describes a photo-sensitive LCD module that can be used as both a light-controlling visor and a multi-display. It uses two comparator circuits to control the LCD in either visor or display mode. In visor mode, the LCD acts as a light filter, becoming darker with increasing light intensity to prevent excessive light. In display mode, the number of LEDs lighting up is adjusted based on light intensity to keep the display visible, even in bright sunlight. The system provides an intelligent display solution for mobile screens and other uses that can automatically adjust based on ambient light conditions.
![Dr. M.G.R. EDUCATIONAL AND RESEARCH INSTITUTEDr. M.G.R. UNIVERSITY(Estd. Under Sec. (3) of UGC Act. 1956.)1771650222885MINI PROJECT ON PHOTOSENSITIVE LCD MODULE CUM VISOR/DISPLAYSUBMITTED BY:-RISHI RAJ SAIKIA (081071101123)GAUTAM KAUSHIK DUTTA (081071101176) K. BIKRAM SINGHA (081071101184)<br />ABSTRACT<br />In the proposed paper we are going to demonstrate an advance controlling of transparent LCD.The system commencing this operation is named as PHOTO-SENSITIVE LCD MODULE CUM VISOR/DISPLAY (PSLVD). With the help of PSLVD a transparent LCD can be used both as light controlling visor as well as a multidisplay. This device on visor and multidisplay mode is controlled only by two separate comparator circuitry.<br />The LCD acts as a filter according to the light intensity in visor mode and as a intelligent display solution to mobile screens.<br />The above LCD can also used be switched into a display which will be readable during high sunlight also which will be done by active backlight adjustments and contrast adjustment. <br />The main blocks of the circuitry are-<br />,[object Object]](https://image.slidesharecdn.com/ads-110708130603-phpapp01/85/Ads-1-320.jpg)
