LED shelf screen features and parameters
product detail
1. Chengtong shelf screen is a product specially tailored for supermarkets and shopping malls. Conventional length 600mm, width 60mm, and length 300mm, width 60mm can be arbitrarily spliced, matching the shelf design of most supermarkets on the market. In addition, the 1.875 dot pitch design is adopted, and the screen display is clearer. 2. High-definition and high-brush light board, low power consumption, energy saving and environmental protection, using COB packaging, ultra-high protection, no fear of bumps, frictions, etc. from carts or customers, no fear of accidental water spray, etc., while increasing the durability of the product 3. The product only needs to reserve the power supply and signal interface, plug and play, easy to install, and can be directly fixed on the shelf through the connecting piece on the back of the screen with screws Product name: LED shelf screen Overall size: 600*60*36.5mm Weight: 1.65kg Box material: iron Pixel pitch: 1.856mm interface: parameter: model Shelf screen Module Resolution (W/H) 160*32 Module size 300*60mm screen size 600*60mm pixel density 284444 brightness ≥600cd/ ㎡ white balance color temperature 3200-9300K adjustable Refresh rate (Hz) ≥1920 Contrast ≥3000:1 Maximum power (W/m²) 600 Average power (W/m²) 260 Supply voltage DC4.2-5V Driver IC High gray-scale constant current source driver IC grayscale 65536 Continuous working time ≥72H LED life (H) 100000 Our Services 1. 27 Years professional led display manufacturer, 2.

If there is any special requirement, it is necessary to make changes of part installation scheme, we will coordinate with users. Our company can ensure the consistence of completion time and contracted time. Any problems caused by natural factors or man-made, we will discuss with client to find solutions. 2) Our company can train the users based on the manual. The training include system use, system maintenance and equipment protection FAQ Q1. Can I have a sample order for led light? A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable. Q2. What about the lead time? A: Sample needs 3-5 days, mass production time needs 1-2 weeks for order quantity more than Q3. Do you have any MOQ limit for led light order? A: Low MOQ, 1pc for sample checking is available Q4. How do you ship the goods and how long does it take to arrive? A: We usually ship by DHL, UPS, FedEx or TNT. It usually takes 3-5 days to arrive. Airline and sea shipping also optional. Q5. How to proceed an order for led light? A: Firstly, let us know your requirements or application. Secondly, we quote according to your requirements or our suggestions. Thirdly customer confirms the samples and places deposit for formal order. Fourthly We arrange the production. Q6. Is it OK to print my logo on led light product? A: Yes. Please inform us formally before our production and confirm the design firstly based on our sample. Q7: Do you offer guarantee for the products? A: Yes, we offer 2-5 years warranty to our products. Q8: How to deal with the faulty? A: Firstly, our products are produced in strict quality control system and the defective rate will be less than 0.2%. Secondly, during the guarantee period, we will send new lights with new order for small quantity. For defective batch products, we will repair them and resend them to you or we can discuss the solution including re-call according to real situation. Q: What is the brightness, viewing angle and wavelength of the LED? A: Luminous Intensity is equal to the amount of luminous flux emitted into a very small solid angle at a defined angular orientation from the light source. The measurement for luminous intensity is the candela. Symbol is Iv.Viewing Angle is the total cone angle in degrees encompassing the central, high luminous intensity portion of the LED beam from the on-axis peak to the off-axis point where the LED intensity is 50% of the on-axis intensity. This off-axis point is known as theta one-half ( 1/2). Two times 1/2 is the LEDs' full viewing angle; however, light is visible beyond the1/2 point.Wavelength is the distance between two points of corresponding phase and is equal to waveform velocity divided by frequency. It defines what color human eyes could recognize Q: What is dominant wavelength? Please specify the ranges of wavelength in red, green and blue color respectively. A: Dominant wavelength is defined as the best range of wavelength showing the most natural color recognized by human eyes. Researches indicate that fixed colors with wavelength of 620-630nm (red), 520-530nm (green) and 460-470nm (blue), in fact mixed in a particular proportion, can get the pure white. That is, in display field, people use luminous materials with above wavelength to make "compounded" white more natural.In order to get a good balance white led display, we specify the led colors with wavelength within 4nm for each color Q: Which chip vendors are you buying from? A: It depends on the Customer's requirement. We can purchase from Japan, Korea, Europe, USA. We are using chips mainly from Taiwan Q: What is the chip size you're using for outdoor display? How about indoor display? A: For outdoor display, we're using 12mil chip for red, 14mil for both green and blue. Regarding indoor display, 9mil for red, 12mil for green and blue are currently adopted
