Display principle of OLED display technology_ LCD display manufacturers1

The display principle of LCD for Samsung display technology_ LCD screen manufacturers OLED display technology is different from traditional mobile phone LCD screen methods. It does not require a backlight and uses very thin organic material coatings and glass substrates. When current passes through, these organic materials will emit light. . Moreover, the LCD for Samsung display screen can be made lighter and thinner, has a larger viewing angle, and can significantly save power. The basic structure of OLED is a thin and transparent indium tin oxide (ITO) with semiconducting properties, which is connected to the positive electrode of electricity, plus another metal cathode, wrapped into a sandwich structure. The whole structural layer includes: hole transport layer (HTL), light emitting layer (EL) and electron transport layer (ETL). When the power is supplied to an appropriate voltage, the positive holes and the negative charges will combine in the light-emitting layer to produce light, and the three primary colors of red, green and blue RGB will be produced according to their formulas to form the basic colors. The characteristic of LCD for Samsung is that it emits light by itself, unlike TFTLCD which needs backlight, so the visibility and brightness are high, followed by low voltage demand and high power saving efficiency, plus fast response, light weight, thin thickness, simple structure, low cost, etc. , is regarded as one of the most promising products in the 21st century. In order to illustrate the structure of OLED, each OLED unit can be compared to a hamburger, and the luminescent material is the vegetables sandwiched in the middle. Each OLED display unit can controllably generate three different colors of light. Like mobile phone LCD, OLED also has active type and passive type. In passive mode, the unit selected by the row and column addresses is lit. In the active mode, there is a thin-film transistor (TFT) behind the OLED unit, and the light-emitting unit lights up under the drive of the TFT. Passive OLEDs save power, but active OLEDs have better display performance. The advantage of OLED is that it is light and thin, and its thickness is only one-third of that of LCD; because it is a solid structure, it has better shock resistance and is not afraid of falling; the viewing angle is large, and the picture is still not distorted even when viewed from a large viewing angle; The display time is fast, and there will be absolutely no smearing phenomenon; the low-temperature characteristics are good, and it can still be displayed normally at minus 40 degrees; the manufacturing process is simple, the cost is low; the luminous rate is high, and it can be manufactured on substrates of different materials.
