color wheel the projector can create approximately 16.7 million colors. The light then shines onto a chip fixed with up to 2 million little mirrors. Electronic impulses will then turn on and off the mirrors depending on the color that needs to display at that moment. One color is shown at a time‚ but the colors are displayed so quickly they appear to blend into the correct color. This is a single chip DLP projector. The DLP projector was invented in 1987 by Dr. Hornbeck. He worked at Texas Instruments

other. 4.2 Availability of Substitute Inputs LCD TV produces colour using active-matrix technology. An active-matrix display‚ also known as thin-film transistor (TFT) display has recently been replaced by using a newer type of TFT technology‚ which is the organic LED (OLED). It uses organic molecules that product a brighter and clearer display comparing to the standard TFT displays. Other than that‚ OLEDs are also cheaper to product‚ while consuming less power (Shelly‚ Cashman and Vermaat 2008‚ 304)

explore the OLED field. In Japan‚ Sharp transferred to be a small and medium-sized panel vendor‚ produced mobile phone panels with 8.5-generation lines and vigorously developed IGZO technology. Hitachi‚ Sony and Toshiba set up a joint venture —— Japan Display (referred to as JDI) to develop LTPS technology. Taiwanese vendors developed 4K HD technology. Chinese mainland vendors promoted the construction of new production lines at low costs aggressively. As a result‚ Chinese mainland vendors are the most

from the ADE 7751 IC and calculates the units. The LCD panel displays the unit consumed. Each module have a unique id which is allotted by KSEB. These values are sent to the reader device‚ when requested‚ using the zigbee module attached to the system. All the functions are controlled by the microcontroller based embedded system. This system calculates the units consumed and sends the data to the LCD display panel. The system is tamperproof also. The system can be jammed

99 000 RPM Contact-Less Digital Tachometer Featuring LCD display and automatic DATA hold function By Ibrahim Kamal Last update: 14/7/10 This article describes how to build a contact -less tachometer (device used to count the revolutions per minute of a rotating shaft) using a 8051 microcontroller and a proximity sensor. As the name implies‚ what makes this device special‚ is that it can very accurately measure the rotational speed of a shaft without even touching it. This is very interesting

a pair of sensors (Transmitter and receiver) which gives the output to the microcontroller. The timer and the counter of the microcontroller gives the speed of the rotating shaft. The microcontroller is interfaced with an LCD to display the speed. The LCD directly displays the speed of the device in rpm. The controller is selected based on the high processing frequency it needs to meet. The concept of the contact-less tachometer can be enhanced and implemented in industries like recycling facilities

Display messages are stored in interrupt service routine. Microcontroller sends corresponding message to alert congestion to GSM modem. The message is also displayed on LCD display. GSM modem transmits the message in form of short message service (SMS) in all receiving modems in surrounding junctions. When other modems receive the message
