6、isplay Operating ModeTransmissive mode, normally whiteSurface TreatmentHard coating(3H) Anti-glare treatment of the front polarizer The LB121S02-A2 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent Lamp (CCFL) backlight system. The matrix employs a-Si Thin Fil

7、m Transistor as the active element. It is a transmissive type display operating in the normally white mode. This TFT-LCD has 12.1 inches diagonally measured active display area with SVGA resolution(600 vertical by 800 horizontal pixel array). Each pixel is divided into Red, Green and Blue sub-pixels

8、 or dots which are arranged in vertical stripes. Gray scale or the brightness of the sub-pixel color is determined with a 6-bit gray scale signal for each dot, thus, presenting a palette of more than 262,144 colors. The LB121S02-A2 has been designed to apply the interface method that enables low pow

9、er, high speed, low EMI. The LB121S02-A2 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 sub-pixels, the LB121S02-A2 characteristics provide an excellent flat display for

13、Electrical Specifications3-1. Electrical CharacteristicsThe LB121S02-A2 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 un

The performance

16、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

17、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. 1. VCC=3.3V, 25C, fV (frame frequency) =

18、 60Hz condition, whereas Mosaic pattern(Typ).,full black pattern(Max) is displayed. 2. The variance of the voltage is 10%. 3. The typical operating current is for the typical surface luminance (LWH) in optical characteristics. 4. The voltage above VS should be applied to the lamps for more than 1 se

19、cond for start-up. Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current.7 / 255. The output of the inverter must have symmetrical(negative and positive) voltage waveform and symmetrical current waveform.(Unsymmetrical ratio is less than 10%) Please do not use

20、the inverter which has unsymmetrical voltage and unsymmetrical current and spike wave. Lamp frequency may produce interference 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

21、frequency and from its harmonics in order to prevent interference. 6. Lets 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 not less than 95%. 7. The lamp power consumption shown above does not inc

22、lude loss of external inverter. The used lamp current is the lamp typical current. (2 Lamp) 8. The life time is determined 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 2C. Requirements for

23、a system inverter design, which is intended to 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 asymmetry rate of the inverter waveform should be less than 10%. b. The dis

24、tortion rate of the waveform should be within 2 10%. * Inverter output waveform had better be more similar to ideal sine wave. Do not attach a conducting tape to lamp connecting wire. If the lamp wire attach to a conducting tape, TFT-LCD Module has a low luminance and the inverter has abnormal actio

25、n. Because leakage current is occurred between lamp wire and conducting tape.I pI -p* Asymmetry rate: | I p I p | / Irms * 100%* Distortion rate I p (or I p) / Irms3-2. Interface ConnectionsThis LCD employs Three interface connections, a 41 pin connector is used for the module electronics interface

26、and the other connectors are used for the integral backlight system. The electronics interface connector is a model DF9B-41P-1V manufactured by Hirose or equivalent. Table 3.
