Display Principles of LCD and OLED and Their Benefits

Before we introduce the display technology, let's briefly introduce the display principles of LCD and OLED.



LCD (Liquid crystal display) light-emitting principle mainly relies on the backlight layer, usually composed of a large number of LED beads, the backlight layer emits white light, backlight layer and color film between a valve control, which is what we call the liquid crystal layer, it changes the size of the voltage to control the degree of opening and closing of the liquid crystal direction, and then control the size of the emitted light to adjust the ratio of red, green and blue primary colors, and finally present the desired color.



OLED (Organic Light-Emitting Diode) organic self-emitting diode, is the electrode on the light-emitting layer to apply voltage, so that the light-emitting layer of red, green and blue three materials to produce self-emitting, the voltage increases the stronger the light.

OLED in the process requires only two layers of film and glass or plastic substrate, simpler than the process of LCD. The current OLED screen finished display is brighter and more detailed than LCD liquid crystal display, and theoretically more power-efficient. Because OLED material has self-emitting properties, no backlight module and color filter, so the production of three less processes, the cost will be significantly reduced after mass production.

OLED light-emitting color depends on the material of the organic light-emitting layer, so manufacturers can change the material of the light-emitting layer and get the desired color. Active array OLEDs have a built-in electronic circuit system so that each pixel is driven independently by a corresponding circuit.


Today, OLED process equipment is still being improved and there is no standard mass production technology, but the entire production process requires a clean environment and supporting processes and equipment. UIVCHEM is a professional OLED intermediate material manufacturer, no matter what kind of light-emitting organic materials you want, you are welcome to come to our website to find them. We provide you with professional advice and one-stop service solutions.


In the final application scenario, cell phones occupy 70% of the market, some high-end machines are using OLED screens, especially flexible screens. Wearable devices smart watches, VR, etc., all use flexible OLED screens, I believe that with the commercialization of 5G, the panel display industry will certainly have a different change.
