However, when LED displays began to be used for indoor applications using smaller pitch products, the space available for electronic components was squeezed, and as a result, dynamic scan drive (line-scanning drive) based on time-division multiplexing (TDM) came into being. In the early stage, LED displays were mostly used for outdoor applications using larger pitch products, which did not have a physical space limit for driver ICs as they were designed with static scan drive. With an independent voltage power supply, the red, green, and blue LED chips can be separately and accurately powered, providing different voltages to them under the same current, which can ensure that they work at their rated power, thereby improving energy utilization and reducing energy consumption.Ĭommon Cathode VS Common Anode LED display, which is better? LED professionals know that the rated power required for the red, green, and blue chips is different, and ordinary power supply methods cannot separate them and can only provide them with the same power. Additionally, this technology can separate and precisely power the red, green, and blue LED chips. The voltage drop and current loss can be reduced by using the independent voltages power supply method. It is an energy-saving power supply technology for LED displays where the current first passes through the LED chips and then reaches the negative pole of the driving IC, hence the name “common cathode”. It has all of the cathodes of the individual LEDs connected together and to a common terminal, while the anodes of each LED are connected separately.Ĭommon cathode”. Kategori produk : RGB LED.A common cathode LED screen is also called” energy-saving led display”. Special care should be taken if an LED with silicone encapsulation is to used near such substances.ĥ, Please aviod continued exposure to the condensing moisture environment and keep the product away from repid transitions in ambiemt temperature.Ħ, Product in the original sealed package is recommended to be assembled within 24 hours of opening. Impact may scratch the silicone lens or damage the internal circuitry.Ĥ, 4-A The inner diameter of the SMD pickup nozzle should not exceed the size of the LED to prevent air leaks Ĥ-BA plible material is suggested for the nozzle tip to avoid acratching or damaging the LED surface during pickup.Ĥ-C The dimension of the component must be accurately programmed in the pick-and-place machine to insure precise pickup and avoid damage during production Ĥ-D As silicone encapsulation is permeable to gases, some corrosive substances such as H2S might corrode silver plationg of leadframe. It may damage the internal circuitry.ģ, Do not stack together assembled PCBS containing exposed LEDs. Handle the component along the side surfaces by using forceps or appropriate tools.Ģ, Do not directly touch or handle the silicone lens surface. Failure to comply might lead to damage and premature failure of the ledġ. As a result, special handling precautions need to be observed during assembly using silicone encapsulated Led products. Medical equipment and communications equipment Ĭompare to epoxy encapsulant that is hard and brittle, silicone is softer and flexible Althouth its characteristiec significantly reduces thermal stress, it is more susceptible to damage by extemal mechanical force. High relability, hig radiation intensity and easy to solder leads Įlectrucal Optical Characteristics(Tc=25 ℃ ).Build-in addressable IC with Red, green and blue LED three chip inside.*If this size of RGB LED cannot meet your required, 3528 RGB LED, 5050 RGB LED, 2121 RGB LED or 1515 RGB LED are also available Which can make sure we can get the diffused lighting result and then this 1010 RGB LED can be widely use in LED display project.Īddressable 1010(4040 RGB LED SMD LED Size: And at the same time, we also cover the LED with light diffused lens on the top. In this 1010RGB-WSIC, we package three chips and build-in IC together inside this mini SMD LED case. You need to program this build-in IC so that this Addressable LED can work as your design. But at the same time, there will also have an build-in IC inside to control the lighting. Addressable LED, it also the same as RGB LED, there will have three chips with red, green and blue inside. Ther have 4 pins under the bottom of SMD LED, so we can control the color by connect the pins into the circuit. RGB LED, same as the name, there will have three color inside of this SMD LED.
