Product Specification 1.1 Scope: LCD BM190WX2-TJA1 LM190WX2-TJA1 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 WXGA+ resolution (900 vertical by 1440 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 LM190WX2-TJA1 characteristics provide an excellent flat panel display for office automation products such as monitors.

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 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: Definition of White Variation (δW): 13 Surface luminance is the luminance value at center 1 point(1) across the LCD surface 50cm from the surface with all pixels displaying white. For more information see FIG 8. The variation in surface luminance , WHITE is defined as Minimum (P1,P2 …..P9) WHITE = --------------------------------------------- *100 Maximum (P1,P2 …..P9) For more information see Figure 8. 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) Surface luminance with all white pixels Contrast ratio = --------------------------------------------------------Surface luminance with all black pixels 14 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. 15 1.5.5 Chromaticity: The x and y co-ordinates for Reddish, Bluish and User preset mode shall be as below: Reddish Preset (6500K): x=0.313 ± 0.020 y=0.329 ± 0.020 Bluish Preset (9300K): x=0.283 ± 0.020 y=0.297 ± 0.020 1.6 Environmental Requirements: Operating Storage Temperature: 0°C - +40°C -20°C - +60°C Humidity: 15% - 90% 15% - 90% Altitude: 12,000 feet (3,658m) 40,000 feet (12,192m) 1.7 Mechanical and Packing: Monitor Packed Monitor Width: 377.8mm 425 Height: 296.1mm 300 Depth: 160.3mm 110 Weight: 1.7kg 2.4kg Dimension (mm): 16 2.
