2 1. Product Specification
1.1 Scope:
LCD LM230WF3-S2E2
LM230WF3-S2E2 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 23.0 inch diagonally measured active display area with Full
HD resolution (1080 vertical by 1920 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 LM230WF3-S2E2
characteristics provide an excellent flat panel display for office automation products such as monitors.

1.4.4 Defects:
1.4.4.1 Defect Terminology:
Dark Spots / Lines: Spots or lines that appear dark in the display patterns and are usually the result of
contamination. Defects do not vary in size or intensity (contrast) when contrast voltage is varied. Contrast
variation can be achieved through the use of varying gray shade patterns.
Bright Spots / Lines: Spots or lines that appears light in the display patterns. Defects do not vary in size or
13 intensity (contrast) when contrast voltage is varied. Contrast variation can be achieved through the use of
varying gray shade patterns.
Polarizer Scratch: When the unit lights, lines appear light (white) with display patterns dark and do not vary in
size. Physical damage to the polarizer does not damage the glass.
Polarizer Dent: When the unit lights, spots appear light (white) with display patterns dark and do not vary in size.
Physical damage to the polarizer does not damage the glass.
Rubbing Line: Horizontal or diagonal lines that appear gray with the display patterns dark and may have
resulted from an “out of control” rubbing process on the polyimide or “waves” on the BEFs or prism sheets .
Newton Ring: The “rainbow” effect caused by non-uniform cell thickness.
Mottling: When the unit lights, variation / non - uniformity (splotch) appears light (white) with the display and
might vary in size.
Dim Line: When the unit lights, line(s) in the minor (vertical) or major (horizontal) axis appear dim, but not
completely on or off.
Cross Lines Off: When the unit lights , lines in both the minor and major axis do not appear.
Bright/Dark Dot: A sub - pixel (R, G, B dot) stuck off / on (electrical).
1.5 Optical Characteristics:
1.5.1 Brightness uniformity:
The brightness uniformity has to be better than 75% and is calculated according to
to the following formula:
With Y1 to Y9 as the brightness values with all pixels white at the 9 measurement
Positions. Contrast and Brightness set to Max.
1.5.2 Contrast ratio (CR):
1.5.2.1 General CR:
The values specified are at an approximate distance 50cm from the LCD surface at a viewing angle of  and 
equal to 0 °.
Contrast ratio(CR) is defined mathematically as :It is measured at center point(1)
14 Surface luminance with all white pixels
Contrast ratio =
--------------------------------------------------------Surface luminance with all black pixels
1.5.3 Response time:
Response time is the time required for the display to transition from black to white (Decay Time, TrD) and from
white to black (Rise Time, TrR)
The sampling rate is 2,500 sample/sec. For additional information see FIG. 9.
The response time is defined as the following figure and shall be measured by switching the input signal for
each gray to gray.
1.5.4 Viewing angles:
Viewing angle is the angle at which the contrast ratio is greater than 10 or 5. 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. 8.
