The LP140WH1 is a Color Active Matrix Liquid Crystal Display with an integral 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. This TFT-LCD has 14.0 inches diagonally measured active display area with HD resolution(768 vertical by 1366 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 6-bit gray scale signal for each dot, thus, presenting a palette of more than 262,144 colors.
The LP140WH1 has been designed to apply the interface method that enables low power, high speed, low EMI.
The LP140WH1 is intended to support applications where thin thickness, low power are critical factors and graphic displays are important. In combination with the vertical arrangement of the sub-pixels, the LP140WH1 characteristics provide an excellent flat display for office automation products such as Notebook PC.

Optical characteristics are determined after the unit has been ‘ON’and stable for approximately 30 minutes in a dark environment at 25°C . The values specified are at an approximate distance 50cm from the LCD surface at a viewing angle of Φand Θequal to 0°.
FIG. 1 presents additional information concerning the measurement equipment and method.

1. Contrast Ratio(CR) is defined mathematically as
Surface Luminance with all white pixels
Contrast Ratio =
Surface Luminance with all black pixels
2. Surface luminance is the average of 5 point across the LCD surface 50cm from the surface with all pixels displaying white. For more information see FIG 1.
L WH = Average(L 1,L 2, …L 5)
3. The variation in surface luminance , The panel total variation (δWHITE ) is determined by measuring L N
at each test position 1 through 13 and then defined as followed numerical formula.For more information see FIG 2.
Maximum(L 1,L 2, …L 13) δWHITE =
Minimum(L 1,L 2, …L 13)
4. Response time is the time required for the display to transition from white to black (rise time, Tr R ) and from black to white(Decay Time, Tr D ). For additional information see FIG 3.
5. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which is normal to the LCD surface. For more information see FIG 4.
