The technological development of mobile / cell phone is no doubt, one of which is the area of the screen. Here we discuss the different types of screens in cell phones in black and white (one color, black), passive matrix (STN, TFT) active matrix (TFT, TFD), UFB Samsung and OLED uses.
Monochrome
LCD (Liquid Crystal Displays) are often in this type of dikalkulator, digital watches, and even the phone (again). Liquid crystals by an electric current can be manipulated, so that you can change its shape. How diponsel black and white color block on the black pixels, the light. One of the advantages of white and black is a low power consumption compared to the others.
And after many years, the width of the screen and mobile, colors and details. And the monochrome display is out of date. But there is still a cell phone screen that opens Monochome externalnya really. (What do you think when someone with a phone with black and white screen mobile fine fine .. see if you still write?))
Passive-matrix color display
The first screen of the mobile phone with the technology of passive-matrix color. This technology uses a cable system in the form of the power vertical and horizontal / declare a pixel. This type of screen is more expensive than TFT (see below). But he has a weakness reacts more slowly, the picture quality appears less bright compared to the active matrix type.
You are using a passive-matrix technology, including:
STN - Super Twisted Nematic
CSTN - Color Super Twisted Nematic
Active-matrix color display
The technology uses active-matrix TFT (Thin Film Transistor), which is generally used for laptops. The TFT screen can be set by the transistor in each pixel can be individually enabled and disabled, creating a display crisp, clear images and brilliant answer, and very quickly. But the weakness mempunyain TFT screen, the more expensive and energy.
Another type of screen, including Active Matrix TFD (Thin Film Diode), TFT is the same as the place with a diode in each pixel of the screen. TFD technology combines the excellent image quality and response speed TFT display with low power consumption and low cost of STN.
Samsung UFB
UFB (Ultra Fine and Bright) LCD technology was created and presented by Samsung in 2002. It can only work with 3 mW of power and consumes less than TFT. No doubt, extends the battery life. Mobile phones that will use that type UFB screen finer sizes. (Cool, yes.)
OLED display
OLED (Organic Light-Emitting Diode), also known as LEP (light emitting polymer) and the OEL (Organic Electro-luminescence). This issue is a new generation of display technology, the dots of organic polymers, the light when it is charged with electricity. Compared to LCD, OLED display has the advantage of being much thinner, lighter, brighter, faster, cheaper and consumes less power (no need for a backlight). The only disadvantage of this screen is hard to see if the light source like the sun.
