1 . General Description The is a Color Active Matrix with an integral Cold Cathode Fluorescent Lamp(CCFL) back light system. The matrix employs asi Thin Film Transistor as the active element. It is a transmissive type display operating in the normally white mode. This TFTLCD has a 3.3 inch diagonally measured active display area with XGA resolution(768 vertical by 04 horizontal pixel array). Each pixel is divided into Red, Green and Blue subpixels or dots which are arranged in vertical stripes. Gray scale or the brightness of the subpixel color is determined with a 6bit gray scale signal for each dot, thus, presenting a palette of more than 6,44 colors. The has been designed to apply the interface method that enables low power, high speed low EMI. Flat Link must be used as a LVDS(Low Voltage ing) chip. The 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 subpixels, the characteristics provide an excellent flat panel display for office automation products such as Notebook PC.

2 . Electrical Specifications. Electrical Characteristics The 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. The inverter is an external unit to the LCD.

The specified current and power consumption are under the Vcc = 3.3V, 5, fv = 60Hz condition whereas Black pattern is displayed.. This impedance value is needed to proper display and measured form LVDS Tx to the mating connector. 3. The duration of rush current is about 0ms. 4. The variance of the voltage is 0%. 5. The transformer output voltage in the inverter must be high considering to the loss of the ballast capacitor in the inverter. 6. The lamp power consumption shown above does not include loss of external inverter. 7. The life time is determined as the time at which brightness of lamp is 50% compare to that of initial value at the typical lamp current on condition of continuous operating at Ver.
