Display Products

Display products test and certification is greatly affected by the size of the product, and some displays such as LED display will be used outdoors, environmental reliability and Photobiological safety test are additionally required according to standards and regulations.

HTW, has been focused on the testing and certification services in an early time, and we were certified as an IECEE CBTL. All these ensure our efficiency and accurate testing and certification capability.

The common Display devices are as follows:

LCD display

LED display

    Experience In Testing Process

    1. the reason of radiation test failed

    There are many reasons for EMC radiation tests failed according to the standard, such as interface filtering, cable design, grounding, shielding etc. 

    Generally speaking, it is the problem of PCB design. 

    For TCB, a multilayer board is a recommended choice, as it can reduce impedance.

    The circuit on the PCB board is required to be straight and short.

    2. the problems of product information

    Label, Schematic, User manual, CDF/BOM, PCB layout

    Service Procedure

    1. Provide us with product pictures, product brochures/manuals
