The LS028Q3UW01 model is a Thin Film Transistor-Liquid Crystal Display without polarizer.
The matrix compose a-Si Thin Film Transistor as a active element.
It is a transmissive type display operating in the normally white mode. This TFT-LCD has 2.0 inch
diagonally measured active display area with QVGA resolution (240xRGBx320 pixels) each pixel is divided
into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes. The LS028Q3UW01 has
been designed to apply the interface method that enables low power.
The LS028Q3UW01 is intended to support applications where thin thickness, low power are critical factors
and graphic display are important. In combination with the vertical arrangement of the sub-pixels, the
LS028Q3UW01 characteristics provide an High quality display for mobile phone application.
