0.28 Inch SMD Single Digit LED Display / seven segment display

White SMD LED Displays

  • 0.28″ (inch) digit height.
  • Packaged in tape and reel for SMT manufacturing.
  • Design flexibility (common cathode and anode).
  • Categorized for luminous intensity.
  • The thickness is thinness than tradition display.
  • The product itself will remain within RoHS compliant Version.


  • The SMD type is much smaller than tradition type components, thus enable smaller board size, higher packing density, reduced storage space and finally smaller equipment to be obtained.
  • These devices are made with white segments and gray surface.


  • Suitable for indoor use.
  • Audio equipment.
  • Set top box.
  • Game machine.
  • Channel indicator of TV.

  • Luminous Intensity Measurement allowance is ± 10%.
  • θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
  • It use many parameters that correspond to the CIE 1931 2°. X, Y, and Z are CIE 1931 2° values of Red, Green and Blue content of the measurement.
