Ki ap dirije klasifikasyon ekleraj ki jan yo divize
Apr 06, 2022
When it comes to the division of LED backlighting classification, it is important to first understand what LED backlighting means. LED backlighting refers to the use of LEDs (Light Emitting Diodes) as the backlighting source for LCDs. Compared with the traditional CCFL (cold cathode tube) backlight, LED has low power consumption, low heat generation, high brightness, long life, etc.
Currently, this LED backlight classification can be divided into RGB-LED and white LED. the former utilizes the capability of dynamic zoning backlight technology and the excellent light source of tri-color RGB-LED, which provides a qualitative leap in color and contrast compared with traditional backlight. As a result, it is usually suitable for high quality TV products and generally costs more than 3W. The latter is a relatively common LED backlight source, also widely used in notebook computers and LCD monitors. White LED backlighting usually uses light ingested from the edge of the display, which is different from RGB-LED and traditional backlighting with direct backlighting.
1, Dapre pozisyon ensidans ki ap dirije ekleraj: modil ekleraj ki ap dirije yo divize an de kalite dapre pozisyon ensidans sous limyè a: dwat -desann ak bò- limyè, ki ka apeprè divize an tou dwat-desann RGB-LED, dwat-desann blan LED ak bò-limyè blan LED, elatriye.
2, diferans ki genyen ant RGB-dirije ak blan dirije: RGB-pèfòmans gam koulè ki ap dirije se yon ti kras pi bon, dezavantaj la se ke pri a se pi wo. Sous limyè ki ap dirije blan, byenke yon ti kras pi ba pase RGB-LED nan gam koulè, gen yon rapò kontras relativman wo ak pri teknik ke RGB-dirije pa ka matche.
3, diferans ki genyen ant tou dwat desann ak bò ki ap dirije ekleraj: dirije limyè bò sous emèt limyè soti nan tou de bò nan kò a ak pwojè limyè sou panèl la atravè bati -nan gid limyè segondè transmisyon. Limite epesè LCD a se epesè lanp fliyoresan. Sous limyè bò a sitiye nan pozisyon an pwojeksyon sou tou de bò, kidonk li pa okipe espas ki la nan epesè televizyon an.
Compared with the side light source, the direct down backlight LED can dynamically control the backlight, making it possible to display a high-quality image effect with natural contrast between light and dark by adjusting only part of the light illumination in the desired backlight area (black or dark part of the screen) when representing some images of dark scenes.
