LED Backlight Technology from LED LCD TV

Image
  1. A brief introduction to the characteristics of LED TV. LED TV is directly imaged by LED and adopts the principle of active luminescence. The color LED display screen uses R/G/B three LED lamps to form a pixel, and the image display is realized by controlling the on-off of each pixel. The imaging principle is very similar to that of active luminous plasma. There is no backlight circuit inside the LED TV, and the whole set is very thin (about 2cm). The price is higher, so the current sales are much smaller than LCD TVs, and it will take some time to replace LCD TVs.   2. What is LED backlight In principle, LCD is a bit like a roadside advertising light box. After a certain degree of diffusion, the light source behind it shines uniformly on the transparent film with a picture, thus transmitting a bright picture. The LCD panel is like that layer of film, but its picture is changing. Traditional liquid crystal display devices use CCFL (cold cathode fluorescent lamp) as the light source

LCD TV backlight method produced in recent years is almost all   LED backlight . Nowadays, the backlight of LED LCD TV has entered the peak of maintenance, especially in the last two years of television sets, the failure rate of LED backlight strip is particularly high. LED strip features LED LCD backlight  has multiple groups of LED lights. The backlight is divided into two types of irradiation, slightly different structure: one is the back transparent direct down type, the light source is installed directly on the back of the LCD panel, LED lights directly irradiate the LCD panel. This method often has 4 groups, 6 groups or more groups of LED lights. The second is the side-transparent type. The light source is installed on the side of the thick light guide plate. This method often has one or two groups of LED lights. The arrangement of the two  types of backlighting  is different.   The performance and parameters of several groups of LED lights on the same screen are the same. Each g

LCD TV Backlight LED light Bar Analysis and Maintenance

  Light source structure The backlight source of LED LCD screen consists of multiple groups of  LED backlights . The backlight source is divided into two types of installation: side-entry and straight-down, and the structure is slightly different. Directly under the type is made of LED into a dense array of dots, placed behind, directly irradiate the screen. The straight-down backlight needs to be placed at the back of the screen, and each LED bead has a lens on it, which increases the thickness quite a bit.   Side-entry LED backlighting refers to the LED backlight placed on the side of the screen, the light emitted through the light guide plate to illuminate the entire screen, which can make the whole machine more light book. Side entry LED strip is installed on the top or bottom of the light guide, left or right side.    Light bar structure The performance and parameters of each  LED strip  in the same screen are the same.

How to Choose the Right Led Backlight Strip?

Image
LED strips   are long circuit boards with surface mount device light emitting diodes (SMD LEDs) that can provide lighting for any room. These strips are also known as LED strips or strip lights and often have an adhesive backing for easy installation.   Some of the best LED strips can be used for many different interior design projects, including recessed lighting,  TV backlighting , or kitchen countertop lighting with under-cabinet lighting.   Factors to Consider when Purchasing Location of Use Before deciding which product to use, it is important to determine where the LED strips will be installed.

The backlight of the LED LCD screen has multiple sets of LED lights. The backlight is divided into two illumination modes, and the structure is slightly different: one is the back-through direct type, the light source is directly installed on the back of the LCD panel, and the LED light directly illuminates the LCD panel. This method often has 4 groups, 6 groups or more. Group of LED lights. The second is the side-through type, the light source is installed on the side of the thick light guide plate, this method often has 1 or 2 groups of LED lights. The performance and parameters of several groups of LED lights on the same screen are the same. Each group of LED lights is composed of multiple LED lamp beads, and each LED unit is assembled on a metal strip using a pressure welding process. Each group is composed of multiple LED lamp beads in series. How to distinguish whether the LED lamp beads on an LED strip are all connected in series or segmented in series? One is to look at the p
