1. General Description
This specification applies to the 26.0 inch Color TFT-LCD Module T260XW01. This LCD module has a TFT active matrix type liquid crystal panel 1280x768 pixels, and diagonal size of 26.0 inch. This module supports 1280x768 XGA-WIDE mode (Non-interlace). 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. The T260XW01 has been designed to apply the 8-bit 1 channel LVDS interface method. It is intended to support displays where high brightness, wide viewing angle, high color saturation, and high color depth are very important.

3. Electrical Specification
3-1 Electrical Characteristics
The T260XW01 requires two power inputs. One is employed to power the LCD electronics and to drive the TFT array and liquid crystal. The second input which powers the CCFL, is typically generated by an inverter.

Note: The design of the inverter must have specifications for the lamp in LCD Assembly. The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced by the characteristics of the DC-AC Inverter. So all the parameters of an inverter should be carefully designed so as not to produce too much leakage current from high-voltage output of the inverter. When you design or order the inverter, please make sure unwanted lighting caused by the mismatch of the lamp and the inverter (no lighting, flicker, etc) never occurs. When you confirm it, the LCD Assembly should be operated in the same condition as installed in your instrument. Note: Do not attach a conducting tape to lamp connecting wire. If the lamp wire attach to conducting tape, TFT-LCD Module have a low luminance and the inverter has abnormal action because leakage current occurs between lamp wire and conducting tape. Note: The relative humidity must not exceed 80% non-condensing at temperatures of 40￠J or less. At temperatures greater than 40￠J , the wet bulb temperature must not exceed 39￠J . When operate at low temperatures, the brightness of CCFL will drop and the life time of CCFL will be reduced.

Note: 1.
The specified current and power consumption are under the Vcc=5.0V, 25 ￠J , fv= 60Hz, fCLK=65Mhz condition whereas mosaic pattern (8x6) is displayed and fv is the frame frequency.
Sequence of Power-on/off and signal-on/off
Apply the lamp voltage within the LCD operating range. When the backlight turns on before the LCD operation or the LCD turns off before the backlight turns off, the display may momentarily become abnormal. Caution: The above on/off sequence should be applied to avoid abnormal function in the display. In case of handling, make sure to turn off the power when you plug the cable into the input connector or pull the cable out of the connector. 2. 3. The lamp power consumption shown above does include loss of external inverter at 25￠J . The used lamp current is the lamp typical current The life is determined as the time at which luminance of the lamp is 50% compared to that of initial value at the typical lamp current on condition of continuous operating at 25?ó￠J 2
Note: The output of the inverter must have symmetrical ( negative and positive) voltage waveform and symmetrical current waveform (Asymmetry ratio is less than 10%). Please do not use the inverter which has asymmetrical voltage and asymmetrical current and spike wave. Requirements for a system inverter design which is intended to have a better display performance, a better power efficiency and a more reliable lamp. It shall help increase the lamp lifetime and reduce its leakage current. a. The asymmetry rate of the inverter current and voltage waveform should be 10% below; b. The distortion rate of the current and voltage waveform should be within ??2?ó0%; 1 c. The ideal sine current and voltage waveform shall be symmetric in positive and negative polarities.

Note: 1. Contrast Ratio (CR) is defined mathematically as: Surface Luminance with all white pixels Contrast Ratio= Surface Luminance with all black pixels
1.
Surface luminance is luminance value at point 1 across the LCD surface 50cm from the surface with all pixels displaying white. From more information see FIG 2. When IBL = 6.5mA, LWH =600cd/￠T(typ.) LWH =Lon1 Where Lon1 is the luminance with all pixels displaying white at center 1 location.
2.
The variation in surface luminance, ￡_WHITE is defined (center of Screen) as: ￡_ WHITE(5P)=Maximum(Lon1 ,
Lon2 ,… ,Lon5 )/Minimum(Lon1 , Lon2 ,… Lon5 )
3.
Response time is the time required for the display to transition from to black (Rise Time, TrR) and from black to white (Decay Time, TrD ). For additional information see FIG3.
4.
Viewing angle is the angle at which the contrast ratio is greater than 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 FIG4.
