For standard product spec please check in


       The Liquid Crystal Display Module (LCM) products we built are widely applied in the personal electronic end products, the household appliances, the industrial and/or the commercial equipment and instrument, the handheld gadget and telephone, etc..

      Our products include Alphanumeric (segment) LCM, Character dot-matrix LCM, and Graphics dot matrix LCM, small-middle TFT LCM. We have the standard series and the customized series, of which is upon the customer’s request.

      Our engineers in electronic circuit design, in the module structure and in the test software are stand-by for serving you and satisfying you. Tell us your requirement, or fill in the Check-list for Custom Design LCMs the specification you want.

The business procedures: Make a deal with us

1 Discuss and exchange the specification, drawing

  1.1 If you don’t know more the spec about the LCD/LCM, we’ll prepare one spec checklist for you and send you, after you preliminarily accept the initial quotation and the terms.

  1.2 You need to let us know below the basic info for the spec/darwing:

1.2.1 The application, applying in what kind of industry or equipment?

1.2.2 The LCM and/ or the LCD outline size, the viewing area size. The installing size of the holes in the PCB, if it’s in COB

1.2.3 The range of viewing angle? TN, HTN, STN or TFT? The dot matrix number and lines, if not an alphanumeric.

1.2.4 The display mode, positive or negative; or the colors of the background, and the character/ dot displayed.

1.2.5 Specifying the driver /controller IC, model number and the packaging way, in COB(chip on PCBoard), COG(chip on glass), or TAB.

1.2.6 Connecting ways for LCD and for the module;

1.2.7 Spec of the backlight? LED qty and color? FPC length and the connecting way, soldering or connector, etc..
