New Screen Demonstrations at the Society of Information Display 2010

Society of Information Display (SID) held 2010 International Symposium, Seminar, and Exhibition from May 23 to May 28, 2010 at Washington State Convention Center, Seattle, WA, USA. The SID, that is now in its 48th year, is the major international event for scientists, engineers, manufacturers, and users in the electronic-display industry. Below is a brief review for only three of many products presented this year.

Samsung has presented an ultra energy-efficient USB-powered monitor. It is an 18.5" LCD display capable of running exclusively from USB - no adapter required. It is an extremely energy efficient display. Built with LED backlight, Samsung has been able to drop the peak power consumption down to only 6.3W. That is why the device can function from bus power over USB.

SONY has introduced a rollable (bendable) OLED display. The flexible OLED measures 4.1" and is only 80 micrometers thick. To reach the goal of a rollable display, SONY developed OTFT - organic TFT (thin film transistor) with original organic semiconductor material. The rollable OLED has a resolution of 432x240 pixel, 16.8 million colors, and contrast ratio 1000:1.

LG has showed the largest 3-D display in the World. This display is a gigantic 84" ultra high definition (UHD) 3-D panel with 3840x2160 resolutions. That is four times the resolution of previous full HD TV panels with (1920x1080). To enable watching in 3-D, the display requires a polarized glasses.

How to Get the Best Quality of LCD Screen

It is easy to take the quality of LCD screen for granted. But when you consider that you spend more time using your LCD monitor than any other component of your PC, you realize that the screen you stare at every day is a vital part of your computer system. What differentiates one LCD panel from another is image quality. The light source, the viewing angle, and the system's graphics card can have a dramatic effect on an LCD's performance. Also such parameters as, text readability, sharpness, grayscale range, color quality, or image uniformity are important.

Make sure that a display is adjusted to perform optimally, based on the manufacturer-recommended or default settings when possible. Ensure that your video card is set to the LCD Monitor's optimal resolution. Evidently, the most important tool (diagnostic equipment) to evaluate the quality of LCD screen is the human eye. Adjust the display settings on your computer so the brightness of the screen is about the same as your work environment. Also, adjust the screen settings to make sure the contrast between the screen background and the on-screen characters is high. And make sure that the text size is optimized for the most comfort. Use Control Panel > Display Settings > Advanced > Monitor and set up "Screen refresh rate" (frequency) to a maximum possible. According to the eye experts refresh rate should be 70 Hz or higher.

LCD screens often have trouble reproducing all of the levels of the grayscale (the range of grays between true black and true white). When producing a bright white image, many LCD screens oversaturate the grayscale: the lightest grays of the scale are lost in the white background. Oversaturation can also lead to loss of color range - a poor color reproduction of a LCD screen at the brightest end of the scale, closest to white. A color-tracking error occurs when the intensity of red, green, and blue (RGB) do not adjust identically with signal-level changes for LCD screen. This lack of balance between the RGB channels affects color as well as grayscale, but it is most easily identified as a shift in color within shades of gray.

Perfectly uniform backlighting across an LCD's entire display surface is difficult to achieve. It is not uncommon for an LCD to have bright or dim patches or subtler variations in color intensity, which give the appearance of shading across the screen, or variable color intensity on the LCD display. Additionally, using a dark screen is the easiest way to spot glare and reflection problems, both of which can have distracting effects when you are viewing an LCD screen.

LCD screens are vulnerable. Dead pixels can occur when the screen is damaged or pressure is put upon the screen. Unfortunately, few manufacturers replace screens with dead pixels under warranty. A cracked or broken LCD display is not repairable and requires a new LCD screen to be replaced. Luckily, it is easy to replace even if you are not a technical person. Since most computer's manufacturers charge too much, you may try to find third-party companies on the market that are selling LCD screens. Some places carry a large inventory of brand new LCD screens. If you are unable to find a particular model listed on the websites, you can call or email them.
