Something about Display Technology

These are some of the facts and figures related to Display Technology.

1. A refresh rate of 85 MHz on your monitor means that every single pixel is refreshed 85 times a second.

2. Moire is a graphic effect that puts an undesirable pattern composed of small dots placed in a tight pattern on plain image.

3. A nematic liquid crystal is a transparent liquid that is used in twisted nematic displays, the most common form of liquid crystal display.

4. Self-scanned Amorphous Silicon integrated Display (SASID) technology is used in flat-panel displays in notebook and portable computers.

5. TOLED (transparent organic light-emitting device) is a display technology being developed by the Universal Display Corporation (UDC). It uses transparent electrodes and light emitting materials in an organic light-emitting device(OLED).

6. The stair-step effect that can be seen in diagonal line of some computer graphics is called 'thejaggies'.

7. In a computer monitor, the voltage gets boosted to 30000 volts in parts of the circuitry.

8. The concept of plasma display panels was first conceived in July 1964 at the University of Illnois.

9. Plasma monitors do not come with in-built tuner. AN NTSC/ATSC television signal must be passed through a satellite box, cable box, HDTV reciever, VCR/VHS device, or an outboard tuning device.

10. Unlike traditional displays, where the image is scanned across the screen, in plasma displays, pixels are'lit' all at once.

11. Plasma technology is different from that used in other display systems,in that red,blue, and green light is created in every pixels, reducing space. Charged electrodes between glass panels cause tiny pockets of inert gas to change the state of the plasma. This process cause ultraviolet light to be produce, which in turn reacts with the phosphorous in each pixel to produce visible light.

12. Plasma screens have no scan line due to the fact that each and every pixels has its own transistor electrode. This creates a smooth evenly lit image across the entire surface of the display.

13. In 1968, a research group at RCA in the US, headed by George Heilmeier, developed the first LCDs based on DSM, or dynamic scatering mode.

14. S Kobayashi of Japan produced first detect-free LCD. This was in 1972.

15. NEC, in 1986, produced the first LCD laptop computer.

16. Sharp produced the 28-inch TFT LCD in 1995.

17. LCDs were first put into use as displays in electronic calculators.

Do you have a Blogger(blogspot) Blog and do you know Google is deleting blogger blogs??

As usual, I was checking backlink tool to find some of the friends link (who has linked backed to me before) if they still have my link backlinked to me or not. Well, some of them didn't link back to me. I checked their site and the message I got upon visiting their blogspot(blogger) blog was something like "this blog has been deleted." As I was visiting some of the other blogspot blog, I found few of them got deleted too. I thought, may be they got over blogging. Recently more and more blogspot(blogger) blogs are unavailable or being deleted. Now, these things forced me to think why those blogs are being deleted. I usually check official google blog for any kind of stuff they are upto. Their blog was shut down too(it's some days before), they are online now though. But, it's quite eerie because this very blog of mine is hosted on blogger's server too. I don't know what happened to their official blog but it's confirmed news they are deleting blogs. M
