General Description
Description
LTA550HQ23 is a color active matrix liquid crystal display (LCD) that uses amorphous silicon TFT(Thin Film Transistor) as switching components. This model is composed of a TFT LCD panel, a driver circuit, and a back-light unit. This 46.0” model has a resolution of 1920 x 1080 pixels (16:9) can display up to
1.07 Billion colors(Dithering) with the wide viewing angle of 89° or higher in all directions. This panel is intended to support applications by providing an excellent performance for the display products with a flat panel such as Home-alone Multimedia TFT-LCD TV and a High Definition TV.

Notice
(a) Setup for test equipment
The measurement should be executed in a stable, windless, and dark room for 40min and 60min after operating the panel at the given temperature for stabilization of the standard light. This measurement should be measured at the center of screen. The environment condition: Ta = 25 ± 2 °C
Note (1) Definition of contrast ratio (C/R)
: The ratio of gray max (Gmax) & gray min (Gmin) at the center point ⑤ of the panel
Gmax : The luminance with all white pixels Gmin : The luminance with all black pixels
Note (2) Definition of the brightness uniformity of 9 points (Test pattern : The full white)
Bmax : The maximum brightness Bmin : The minimum brightness
Note (3) Definition of response time : Sum of Tr, Tf
※ G-to-G: Average response time between the whole gray scale to the whole gray scale.

* Measure the size of background pattern at the interval of 4 grays with excluding the size of white
rectangle within the range from gray 1 to gray 64. * Measure the horizontal crosstalk and vertical crosstalk both. * The maximum value among measured values can be defined as a crosstalk.
Reference: The color of rectangle for Gmin is black when the color of screen is white.
The color of rectangle for Gmax is white when the color of screen is black.
