As soon as the public heard about the led display and the Oled display, their heads were confused. Isn't this the same? In fact, the difference between them is not just a letter difference, the two are completely different imaging technologies. The led display screen is a collection of microelectronics technology, computer technology, and information processing. It is known for its bright colors, wide dynamic range, high brightness, long life, and reliable performance. It is also the most advantageous public display media. With the continuous development and innovation of LED display technology, the LED display industry starts with products, and then to product design, so that the future can provide overall solutions.
The main advantage of the led display is its ultra-high brightness and large-screen display, which can meet the needs of outdoor all-weather and full-color display. The large color LED screen can express the sky and the ocean and realize three-dimensional animation. The led display screen can be assembled into various structures according to the pixel size. The diameter of small pixels is generally less than 5mm. Full-color display requires 3 T-1 red, green and blue lights, or a multi-chip T-1 (3/ 4) The LED light is used as a pixel. The lifelike full-color performance of the led display has a large color range including: blue-green, green-red, etc., which is basically in line with the TV color range specified by the International Television System Committee (NTSC).
The new generation of red, green, and blue ultra-high-brightness LEDs have achieved unprecedented performance and can realize splicing display. BSV LCD splicing technology is adopted to realize large-screen high-brightness display.
Oled displays are widely used in various electronic products
OLED is the abbreviation of OrganicLight-EmittingDiode in English, and can be called organic light emitting diode or organic light emitting display. As an emerging application technology of flat-panel displays, OLED is also self-luminous, does not require a backlight, has high contrast, uniform picture quality, wide viewing angle, and fast response speed.
It conforms to the principle of short information and is not only used in small and medium-sized panels. And because OLED is an all-solid-state, non-vacuum device, it has the characteristics of shock resistance and low temperature resistance, and it also has important applications in the military. Due to the rapid development of industries such as smartphones, tablet computers, and car audio in the downstream market, the Oled display industry has grown rapidly, and the market scale has continued to expand.
The difference between led display and Oled display lies in imaging technology
The led display screen is a display method that controls semiconductor light-emitting diodes. It is usually composed of multiple red light-emitting diodes, and the display is dominated by the brightness of the lights. So as to realize the display screen of various information such as text, graphics, image, animation, video, video signal and so on. OLED emits light by driving the organic film itself by electric current. The light emitted can be monochromatic such as red, green, blue, white, etc., and then achieve a full-color effect, which belongs to a new light-emitting principle. This is the most essential difference between the two.
