1. What are the Basics of Liquid Crystal Display? 2.1. Where does LCD display rely?
The display relies on a backlight to illuminate colored filters placed behind each sub-pixel. 2.2. What is the purpose of liquid crystals?
Liquid crystals can be made to become opaque and block the passage of this colored light, or they can be made to allow the light to pass through to the front of the screen, depending upon the electrical charge applied to each sub-pixel. 2.3. What makes up the apparent color of each pixel on the screen?
The combination of the color and intensity of the three sub-pixels makes up the apparent color of each pixel on the screen. 2. What is Addressing? 3.4. How does addressing occur?

    Lcd vs Plasma

    For instance, a plasma display is comprised of two parallel sheets of glass, which enclose a gas mixture usually composed of neon and xenon that is contained in millions of tiny cells sandwiched in between the glass. Electricity, sent through an array of electrodes that are in close proximity to the cells, excites the gas, resulting in a discharge of ultraviolet light. The light then strikes a phosphor coating on the inside of the glass, which causes the emission of red, blue or green visible light. Based on the information in a video signal i.e. DVD movie, TV signal or a video game, the television lights up thousands of tiny dots called pixels with a high-energy beam of electrons. In most systems, there are three pixel colors—red, green and blue—which are evenly distributed on the screen Each, pixel by the way, consists of one red, one blue and one green sub-pixel. The three colors in each pixel combine according to the amount of electric pulses fed to each sub-pixel, to create visible images.…

With the conversion to digital format 1080i in 1998, there has been a boom in the production of different types and technologies for Televisions. A new generation of televisions has been developed, including liquid crystal display (LCD), rear projection, and high definition that provide amazing visual characteristics and can be integrated in to a home theater system. As the technology behind these televisions decreases in costs, more companies are entering the market. DLH Visions is a company that has a vision for producing three types of high quality visual displays.

    Usmania Glass Sheet

    Usmania Glass Sheet

    Usmania Glass Sheet Factory Ltd is the first glass sheet factory in Bangladesh. It was established in 1959. The oldest glass sheet plant in Bangladesh is situated in the southern side of the country at the district of Chittagong. It started its commercial production in 1961 but after the liberation war in 1971, it was taken by the government of Bangladesh and was subsequently placed under Bangladesh Chemical Industry Corporation (BCIC). Until 1996 Usmania was the only glass sheet manufacturing company but in 1997 another glass sheet company-‘MEB” was established in Dhaka. Within the last two years there were more competitors in the market like PHP Float Glass Industries Limited and Nasir Glass Limited (NGL), who came into the industry with advanced technology and capacity. Thus Usmania Glass Sheet Limited is losing its market share. Without the proper innovation, and weak marketing and strategic planning the company is in a desperate situation of becoming bankrupt. It is also government regulated company and it does not have the drive to compete against its competitors due to corruption. The company is not at all thinking about re-engineering its facilities and machineries to cope up with the industry environmental change. Therefore the government is suffering heavy losses.This was the first glass sheet-producing unit in this industry. But glass sheet companies are not developed in our country as for need. Usmania was monopoly in this line up to 1996. And in 1997 another glass sheet factory “MEB” was established in the capital city. It is a part of ISLAMIC BROTHERS. But within last two years the following organizations came into the market with more advanced technology and capacity.…
