LED heat dissipation technology, manufactured by semiconductor light-emitting diode, works on the principle of radiation compound electroluminescence, is the most common way of heat dissipation, aluminum heat dissipation fin as part of the shell to increase the heat dissipation area. Like traditional light sources, semiconductor LED light-emitting diodes generate heat during operation, depending on the overall luminous efficiency. Under the action of external electric energy, the radiation of electrons and holes compound to produce electroluminescence, and the light radiated out near the PN junction also needs to pass through the semiconductor medium and packaging medium of LED chip itself to reach the outside world (air). 0.32 inch 3311AS LED Common-Cathode CC 3311AS 7-Segment digit 3311BS Display 3311BS Common-Anode CA 0.32 inch 3231AG LED Common-Cathode CC 3231AG 7-Segment digit 3231BG Display 3231BG Common-Anode CA The laboratory has an experienced LED failure analysis technical team. For LED chip failure analysis, the laboratory will first clarify the background of the analysis object, confirm the failure phenomenon, then develop LED failure analysis plan, study the failure causes and mechanism of LED, and finally propose follow-up prevention and improvement measures. Based on thousands of failure analysis cases, the laboratory summarized the failure causes of LED chips into the following categories. Common-Cathode CC 3942AG LED 3942AG 0.39 inch Common-Anode CA 3942BG 7-Segment 3942BG Display Each model became a hot seller at the time. Not only that, on the basis of Mini LED, TCL also integrates QLED quantum dot technology, which not only realizes ultra-high brightness and ultra-high contrast, but also adds high color gamut of primary colors, greatly improving the color expression, and the screen has a longer service life, 10 years will not fade, which is the current popular market QD-Mini LED technology. It is no exaggeration to say that the QD-Mini LED combines the best of two flagship display technologies. Common-Cathode CC 4021AB LED 4021AB 0.40 inch Common-Anode CA 4021BB 7-Segment 4021BB Display
