Product Specification
1. General description
LM195WD1-TLA1 is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting
Diode(LED) backlight system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive type display operating in the normally white mode. It has a 19.5 inch
diagonally measured active display area with HD+ resolution (900 vertical by 1600 horizontal pixel
array) Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in
vertical stripes. Gray scale or the brightness of the sub-pixel color is determined with
a 8-bit gray scale signal for each dot, thus, presenting a palette of more than 16.7M colors with
Advanced-FRC(Frame Rate Control). It has been designed to apply the interface method that
enables low power, high speed, low EMI. FPD Link or compatible must be used as a LVDS(Low
Voltage Differential Signaling) chip. It is intended to support applications where thin thickness,
wide viewing angle, low power are critical factors and graphic displays are important. In
combination with the vertical arrangement of the sub-pixels, the LM195WD1-TLA1 characteristics
provide an excellent flat panel display for office automation products such as monitors.
