Indoor HD LED Display suppliers Description Our Indoor full hd led panel is a special light-emitting device, as a high-tech medium with efficient information transmission ability, it is widely used in shopping malls, clubs, ports, stations and other places. It is used to play any kind of static or moving pictures, with high brightness and excellent contrast, when you install it behind glass, it has clear visual effect even in strong sunlight or gray cloudy days. Features This Indoor full hd led panel can be specially designed in any size according to your usage needs and the limitations of the installation site. It adopts a seamless connection design, and the entire screen has natural color effects, providing passers-by with a high-definition viewing experience. Moreover, the cabinet adopts a fully front-mounted design, when you remove the module, its power supply, cables and other components can be quickly removed from the front, which makes your installation and maintenance work very simple. Advantages 鈼廐UB board hard connection design, stable and reliable signal transmission. 鈼廡he internal wiring of the cabinet is small, clean and tidy, and the failure rate is low. 鈼廎ast magnetic front maintenance design, simple and fast installation and maintenance. 鈼?/b>The indoor videowall weight of the box is only 3.8KG, which is convenient for transportation and installation. 鈼?/b>The thickness of the cabinet is only 28mm, which is one of the thinnest cabinets on the market, saving installation space and saving steel structure. the positive pole of the die through the spherical contact point with the gold wire, bonded to the inner lead and connected to a pin, the negative electrode is connected by a reflector cup and another pin of the lead frame, and then the top of which is encapsulated with epoxy resin. The role of the reflector cup is to collect the light emitted from the side and interface of the die and emit it into the desired direction angle. The epoxy resin encapsulated at the top is made into a certain shape, which has several functions: to protect the core from external erosion; to use different shapes and material properties (mixed or not to dope dispersing agents), to play the function of lens or diffuse lens, to control the divergence angle of light; the refractive index of the core is too largely related to the refractive index of air, resulting in a small critical angle of total reflection inside the core, and only a small part of the light generated by the active layer is affected Take out, most of the easy to be absorbed by multiple reflections inside the tube, easy to occur total reflection leads to excessive light loss, the corresponding refractive index of epoxy resin is selected as a transition, improve the light emission efficiency of the tube. The epoxy resin used to form the shell must have moisture resistance, insulation, mechanical strength, and a high refractive index and transmittance of light emitted to the tube core. The selection of packaging materials with different refractive indexes, the influence of the packaging geometry on the escape efficiency of photons is different, and the angular distribution of the luminous intensity is also related to the structure of the tube core, the light output method, and the material and shape used in the encapsulated lens. If a pointed resin lens is used, the light can be concentrated in the axis direction of the LED, and the corresponding viewing angle is small; if the top resin lens is round or flat, its corresponding viewing angle will increase. Under normal circumstances, the luminous wavelength of THE LED changes with temperature to 0. 2-0锛?3nm/掳C, the spectral width increases accordingly, affecting the color vividness. In addition, when the forward current flows through the pn junction, the heat loss makes the junction area produce temperature rise, near the room temperature, every time the temperature rises by 1 掳 C, the luminous intensity of the LED will be correspondingly reduced by about 1%, the package heat dissipation is very important to maintain the color purity and luminous intensity, in the past, more than the use of its driving current method, reduce the junction temperature, most of the LED drive current is limited to about 20mA.Indoor HD LED Display suppliers website:http://www.leder-ledvision.com/indoor-led-screen/indoor-hd-led-display/
