At present, many brands of LED backlight displays are referred to as LED displays. In fact, LED displays are essentially different from current LED-backlit displays. Of course, it is easy for readers to confuse the very advanced technology of OLED. What is the difference between LED, LED backlight and OLED? This article introduces you to the basic concepts of these three technologies.
What is an LED display?
The LED display refers to a display in which LEDs (light-emitting diodes) are directly used as pixel light-emitting elements, and the light-emitting diodes constituting the array directly emit light of three colors of red, green and blue, thereby forming a color picture. However, since the diameter of the light-emitting diode itself is large, the distance between the pixels of the same color is also large (that is, the dot pitch as we often say), so the LED display is generally only suitable for large-screen display.
LED display is widely used in the opening ceremony of Beijing Olympic Games. LED display integrates microelectronic technology, computer technology and information processing. It has become the most popular with its bright color, wide dynamic range, high brightness, long life and stable and reliable operation. The public display media with advantages, at present, LED displays have been widely used in large squares, commercials, stadiums, information dissemination, news release, securities trading, etc., to meet the needs of different environments.
What is an LED backlit display?
LED-backlit displays are simply backlights for liquid crystal displays that are over-extended to LEDs (light-emitting diodes) by conventional CCFL cold-light tubes (like fluorescent lamps).
Basic structure of the liquid crystal panel
The imaging principle of liquid crystal can be simply understood as that the external voltage is applied to deflect the liquid crystal molecules to block the transparency of the light emitted by the backlight, and the light is projected into the color filters of different colors to form an image.
Rectifier Diode(Standard Diode) utilizes the unidirectional conductivity of the diode, which can convert the alternating current of alternating direction to a pulsating direct current of a single direction. Rectifier diode – diode designed for rectifying alternating current (mostly with low power frequency – 50 Hz at high power emitted during load). The main task of the rectifier diode is to convert AC voltage into DC voltage through application in rectifier bridges. The variant of rectifier diodewith the Schottky barrier is particularly valued in digital electronics.
