OLED liquid crystal will emit light without backlight. LCD liquid crystal will not emit light, so backlight transmission is needed to see the display content.
OLED liquid crystal can emit light without backlight, but LCD liquid crystal can't emit light without backlight transmission.

The difference between OLED and LCD

many netizens easily associate OLED with LED backlight, which is widely hyped by manufacturers.
in fact, OLED and LED backlight are completely different display technologies.
OLED emits light by driving the organic film itself with electric current.
the light emitted can be red, green, green So OLED is a new light-emitting principle different from CRT.
LED and liquid crystal technology.
LED display screen is composed of LED lattice and ledpc panel.
text, picture, animation and video can be displayed by red, blue, white and green LED lights, and the content can be changed at any time, The components of each part are display devices with modular structure.
traditional LED display screen is usually composed of display module, control system and power supply system.
the display module is composed of dot matrix composed of LED lights.
it is responsible for luminous display; The control system can make the screen display text, picture, video and other contents by controlling the lighting of the corresponding area. The monochrome and two-color screens are mainly used to play text. The full-color LED display can not only play text, picture, animation, but also play video and other formats.
at present, it has a wide audience area.
the operation is simple, In general, LED backlight and OLED are three completely different imaging technologies.
1. OLED display.
that is, organic light emitting diode (OLED) display.
2OLED has the advantages of simple structure, self luminous without backlight, high contrast, thin thickness, wide viewing angle, fast reaction speed, can be used for flexible panel, wide temperature range, etc.
in the commercial field, OLED display can be applied to POS and ATM machines, copiers, game machines, etc; In the field of communication, it can be applied to mobile phones, mobile network terminals and other fields; In the field of computer, it can be widely used in PDA, commercial PC, home PC and notebook computer; In the field of consumer electronics.
can be applied to audio equipment, digital cameras, portable DVD; In the field of industrial application, it is suitable for instruments and meters; In the field of transportation, it is used in GPS, aircraft instruments, etc.
Second, LED LCD screen.
LED series products are backlit LCD screens.
LED LCD screen can dynamically adjust the LED brightness of its corresponding position according to the brightness degree of the image and the surrounding color.
as a result, the contrast of the region will realize dynamic conversion according to the requirements of the image, The contrast of each display part of the whole LCD screen is different, and the viewing effect will be much better.
LED series products are widely loved by consumers because of their beautiful appearance and ultra-thin size.
LED belongs to solid-state electronic lighting.
the resistance to heavy impact is higher than CCFL; LED is not as environmentally friendly as CCFL lamp, which has the concerns of gas environmental protection and UV leakage, so it is more environmentally friendly; LED LCD screen is light and ultra-thin; The color saturation of LED LCD is better.
the color saturation of LED LCD is better
