LCD and 3LCD

LCD

Nowadays, LCD display monitors and TVs are getting higher and higher in demand. Frankly, if you have ample of free time, you can visit the nearest electrical store to check out there are LCD TVs which are mushrooming around the shop. The same thing happens on the computing industries, where LCD monitors are getting cheaper and cheaper nowadays. Compared to 6 years earlier, I remembered my uncle bought an IBM 15” monitor for about RM 3500. I was shocked and traumatized as RM3500 can get yourself a Full Set of Desktop PC, complete with 512mb ram and a GeForce 4MX grahic card at the moment. Well, life is like that, when the LCD market grows bigger and bigger, you can even see LCD display on children toys nowadays. Let me put it in another way, we can see LCD displays on watches, cellphones, Astro decoder, TVs, digital alarm clock and so on. LCD stands for Liquid Crystal Display. Based on the facts on www.howstuffworks.com, many people will get puzzled and wondering why Liquid and Crystal can be merged together since they both appear to be solid and liquid. This is a contradictory name if we put Liquid and Crystal together. In the study of Physics, a solid state is the state where molecules are tangled up together and they hardly find space to move. This is why when we try to deform it or burn it the shape will never change in form. Whereas the liquid state is the state that always flow and the molecules will roam freely. It seems to be a contradictory name but they both neither appear in solid nor liquid form.

How do LCDs work? To principles of LCD are subjected to light polarizing between two polarized glasses. When we turn on our LCD monitor, electric current will flow through and heat up the liquid molecules to twist and move around. The two polarized glasses are oriented and positioned in such a way that they are facing 90 degrees to each other. Not only that, but they are required to be in the same vector ( vector means same magnitude and direction ). A voltage drop in the circuit will activate the light beam to penetrate through the two polarized glass. The beam that penetrated the first glass will guide or bring the light into another polarized glass accordingly. The light molecules will react and they will align themselves to twist and vibrate based on the signals received. So, the polarized glasses are actually “co-operating” to display the complete image on the monitor screen.

3LCD

3LCD means three polarized glasses are merged or combined into a single sheet of glass and when the light strikes on the crystal display, the molecules will arrange themselves in pixels form which are comprised of 3 sub-pixels which are the RGB elements (Red, Green and Blue). The 3LCD concept is based on the active matrix technology which is considered to be a better LCD tech compared to the passive matrix technology. In passive matrix technology, it creates an image with a slower response time and less crisp image quality compared to the active effect. Active matrix is commonly known as TFT (Thin Film Transistor) where we usually can see in the specs of the new laptops available in the market nowadays. Don’t get surprised when the LCD is actually built of transistors. As the matter of fact, they are really transistors but the size of them are too minute and couldn’t be detected by human vision without a magnifying glass. The 3LCD uses the active matrix technology.

So a HDTV with 3LCD support usually will put you glued to that television and this is not because of the TV programme, but due to the state-of-the-art image quality which is so crystal-clear and sharp. It is so high-detailed that sometimes some of the viewers will generate incredible imaginations of entering into the TV programme. Below are the main positive properties of 3LCD technology which results in:-

• A brighter picture, lighting conditions wouldn’t affect the image quality
• Natural colors colours are vivid and gives a picture perfect effect
• High detail which put the picture in HD and offers a very crisp and crystal clear pic.
