Foreword: AMOLED, I believe we do not think the word has been getting strange. In the fierce competition in this screen, AMOLED in the end is how to make their own highlights? It is to the advantage of how to attract the public eye it? How it meets the needs of everyone? It is what defects have waited more sophisticated processes to improve it? The topic will be announced all these puzzles.
AMOLED (active matrix organic light-emitting diodes, or active-matrix organic light-emitting diodes, English: Active-matrix organic light-emitting diode), the television and mobile devices in a display technology is applied. Where the OLED (organic light-emitting diode) describes the film show the specific type of technology - organic light-emitting display, AM (active matrix or active matrix body body) refers to the technology behind the pixel addressing.
AMOLED display stored beforehand or integrated in the TFT matrix OLED light emitted after the electric shock by molecule, as a switch to control the current flow to the flow of each pixel. Typically, each pixel consists of two at least the continuous current control TFT. One control charging the storage capacitor, the other to provide a certain level of the voltage source, used to create a constant current pixel and the required runtime passive OLEM high currents cancel out. TFT backplane technology is the key to manufacturing AMOLED display. Today, two major TFT backplane technology, i.e., polycrystalline silicon and amorphous silicon, has been applied to the AMOLED. These techniques for low temperature (less than 150 ° C) under the production of flexible AMOLED displays on flexible plastic substrates may be provided.
Advantages and disadvantages of AMOLED screen
Benefits:
1. Compared to traditional LCD, AMOLED screen is very thin, and can be integrated touch screen layer, ultrathin machine advantage.
2.AMOLED self-luminous, black nowadays do not work for a single pixel in the display, display dark low power consumption.
3.AMOLED can be made flexible screen, compared to the LCD screen glass substrates should not be damaged.
4.AMOLED and SUPER AMOLED very wide color gamut, can reach 110% NTSC. Some on the LCD can not accurately restore the color, can be expressed in the AMOLED. For example, canola flower in full bloom, to have feelings too Wuyuan, in the ordinary LCD is not showing up, because beyond the color gamut of the display. Sharp's high-end LCD screen in order to solve this problem, specifically to increase the expression of the yellow sub-pixel to bright yellow.
5.AMOLED with high contrast, contrast can be theoretically infinite, but not leaked.
6.AMOLED has a fast response speed, response time is only LCD 1/1000 to 1/100.
7.AMOLED compared to passive OLED has a higher refresh rate, energy consumption is also significantly reduced.
Cons:
1.AMOLED immature technology, high score screen they use pentile, with this arrangement, the nominal resolution of less than 70%, it would be more grainy heavy at lower dpi, and a close look at (especially myopia night watch) you can clearly see the color point, light-emitting display needs assistance when adjacent pixels, text edge virtual hair. Strictly speaking, this is not a disadvantage of the AMOLED, LCD because there is also pentile arranged, and there is also a standard RGB AMOLED arrangement. But AMOLED technology difficult, with pentile is yield and lifetime of compromise. The current high score screen, this shortcoming has been very noticeable.
2.AMOLED drive circuit immature Levels over uneven and difficult to control low-light area
3.AMOLED because it is self-luminous, so the aging process of aging may appear different pixel brightness level is not the same as cause is not the same, it may lead to the display left blur. The blue sub-pixel color temperature drift decreases rapidly also lead to problems. The luminescent backlight LCD screen does not have this concern.
4.AMOLED Internet more costly electricity. Pages are mostly white background, the current consumption when the AMOLED LCD display is larger than white!
5.AMOLED too bright, because of the high AMOLED color gamut, but most of the current display content based on low-gamut display s-RGB standard equipment production, suitable for ordinary LCD display on. This is actually not a drawback, high color gamut can tune into low gamut, such as Samsung mobile phones have several color modes adjustable.
6. Compared with liquid crystal displays, in direct sunlight, AMOLED monitor may be difficult to see. Cast serious.
The organic materials used in the display 7.AMOLED easily degraded. However, it has developed a material degradation compensation technology.
8.AMOLED displayed on the same screen for too long can cause the screen Screen burn-in.
9.AMOLED large cost is particularly high yield is particularly low.
