4、1-TLP1 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode FluorescentLamp(CCFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active element. It is a transmissive type

5、display operating in the normally white mode. It has a 19.0 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

6、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 colo

7、rs 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)

8、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, th

15、e LCD electronics and to drive the TFT array and liquid crystal. The second input power for the CCFL/Backlight, is typically generated by an inverter. The inverter is an external unit to the LCDs.,Note : 1. The

16、specified current and power consumption are under the VLCD=5.0V, 25 ? 2°C, fV=60Hz condition whereas mosaic pattern(8 x 6) is displayed and fV is the frame frequency. 2. The current is specified at the m

19、tion Measurement,,Full Black Pattern,Power Input Ripple,Table 2. Electrical Characteristics,7 / 31,Table 3. Electrical Characteristics,Note : The design of the inverter must have specifications for the lamp in LCD

20、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

21、 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 a

22、nd 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 you instrument. ※ Do not attach a conducting tape to lamp c

23、onnecting wire. If the lamp wire attach to a conducting tape, TFT-LCD Module has a low luminance and the inverter has abnormal action. Because leakage current is occurred between lamp wire and conducting tape.

24、 1. Specified values are for a single lamp. 2. Operating voltage is measured at 25 ? 2°C. The variance of the voltage is ? 10%. 3. The voltage above VS should be applied to the lamps for more than 1

25、second for start-up. (Inverter open voltage must be more than lamp starting voltage.) Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current. 4. Lamp frequency may pro

26、duce interface with horizontal synchronous frequency and as a result this may cause beat on the display. Therefore lamp frequency shall be as away possible from the horizontal synchronous frequency and

27、from its harmonics in order to prevent interference.5. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%. TS is the time required for the brightness of the center of the lamp to be

28、not less than 95%. 6. The lamp power consumption shown above does not include loss of external inverter. The used lamp current is the lamp typical current. (PBL = VBL x IBL x NLamp ) 7. The life is determin

29、ed as the time at which brightness of the lamp is 50% compared to that of initial value at the typical lamp current on condition of continuous operating at 25 ? 2°C.,8 / 31,* Asymmetry rate: | I p –

30、I –p | / Irms x 100%* Distortion rate I p (or I –p) / Irms,Note : 8. The output of the inverter must have symmetrical(negative and positive) voltage waveform and symmetrical current waveform (Unsymme

31、trical ratio is less than 10%). Please do not use the inverter which has unsymmetrical voltage and unsymmetrical current and spike wave. Requirements for a system inverter design, which is intended to

32、 have a better display performance, a better power efficiency and a more reliable lamp, are following.It shall help increase the lamp lifetime and reduce leakage current. a. The asymmet

33、ry rate of the inverter waveform should be less than 10%. b. The distortion rate of the waveform should be within √2 ±10%. * Inverter output waveform had better be more similar to ideal sine wave.

34、 9. The inverter which is combined with this LCM, is highly recommended to connect coupling(ballast) condenser at the high voltage output side. When you use the inverter which has not co

35、upling(ballast) condenser, it may cause abnormal lamp lighting because of biased mercury as time goes. 10.In case of edgy type back light with over 4 parallel lamps, input current and voltage wave

36、form should be synchronized,9 / 31,3-2. Interface Connections,Table 4. Module Connector(CN1) Pin Configuration,LCD connector(CN1) : GT103-30S-H23 (LSM), IS100-L30B-C23 (UJU) Mating connector : FI-X30H and FI-X30HL (JAE
