[note2] referential data per one ccft by calculation. (i l ? vl) the data don?t include loss at inverter. ( il=6.0marms) [note3] lamp frequency may produce interference w ith horizontal synchronous frequency, and this may cause beat on the display. therefore lamp frequency shall be detached as much as possible from the horizontal synchronous frequency and from the harmonics of horizontal synchronous to avoid interference. [note4] the voltage above this value should be applied to the lamp for more than 1 second to start-up. otherwise the lamp may not be turned on. [note5] since lamp is consumables, the life time written above is referencial value and it is not guaranteed in this specification sheet by sharp. above value is applicable when lamp (the long side of lcd module) is placed horizontally. (landscape position) lamp life time is defined that it applied either or under this condition (continuous turning on at ta=25 o c, il=6.0marms) brightness becomes 50% of the original value under standard condition. kick-off voltage at ta=-10 o c exceeds maximum value,1450vrms. (lamp lifetime may vary if lamp is in portrait position due to the change of mercury density inside the lamp.) in case of operating under lower temp environment, the lamp exhaustion is accelerated and the brightness becomes lower. (continuous operating for around 1 month under lower temp condition may reduce the brightness to half of the original brightness.) in case of such usage under lower temp environment, periodical lamp exchange is recommended. [note6] the performance of the backlight, for example life time or brightness, is much influenced by the characteristics of the dc-ac inverter for the lamp. when you design or order the inverter, please make sure that a poor lighting caused by the mismatch of the backlight and the inverter (miss-lighting, flicker, etc.) never occur. when you confirm it, the module should be operated in the same condition as it is installed in your instrument. be sure to use a back light power supply with the safety protection circuit such as the detection circuit for the excess voltage, excess current and or electric discharge waveform. be sure to use the detect circuit by which one side of the ccft lamps can be controlled independently. otherwise, when one side of the ccft is open, the excess current may possibly be applied to the other side of the lamp. recommended inverter is ? cxa-p1212b-wjl(tdk) ? . [note7] it is required to have the inverter designed so that to allow the impedance deviation of the two ccft lamps and the capacity deviation of barast capacitor. [note8] under the environment of 10lx or less, miss-lighting or lighting delay may occur. module 9 :* : :* transformer output voltage cn2,3 2pin : :* cn2,3 1pin inverter inverter output voltage ld18203a- 8. timing characteristics of input signals 8-1. timing characteristics (these are specified at the digital inputs/outputs of lvds transmitter/receiver.) c data enab sync d e f a b (vertical timing) item(symbol) min. typ. max. unit ?(( vsync cycle (t va ) - 17.6 - ms negative 628 666 798 line blanking period(t vb ) 28 66 - line vsync pulse width (t vc ) 2 4 6 line back porch (t vd ) 23 23 23 line vsync pulse width+back porch (t vc +t vd ) 25 27 29 line active display area (t ve ) 600 600 600 line front porch (t vf ) 3 39 - line (horizontal timing) item(symbol) min. typ. max. unit remark hsync cycle (t ha ) 20.8 26.4 - us negative 832 1056 - clock blanking period (t hb ) 40 256 - clock hsync pulse width (t hc ) 2 128 200 clock back porch (t hd ) 58 88 170 clock active display area (t he ) 800 800 800 clock front porch (t hf ) - 40 - clock (clock signal) item min. typ. max. unit remark frequency 35 40 42 mhz [note1] [note1] in case of lower frequency, the deterioration of display quality, flicker etc., may be occurred. ld18203a- (hsync-vsync phase difference) t hv vsync hsync item(symbol) min. typ. max. unit remark hsync-vsync phase difference (t hv )1 - t ha -t hc clock (hsync-enab phase difference) enab hsync t hn item min. typ. max. unit remark hsync-enab phase difference (t hn ) 58 88 170 clock 8-2 display position item standards beginning ending unit remark horizontal rising edge of enab 0 800 clock rising edge of hsync 88 888 clock [note1] vertical rising edge of vsync 23 623 line [note1] in case that enab signal is fixed to low level. do not keep enab signal high during operation. 8-3. input data signals and display position on the screen d1,dh1 d1,dh2 d1,dh3 d2,dh2 d2,dh1 d3,dh1 rgb display position of input data ( h , v *% d800, d1,dh600 d800,dh1 dh600 ld18203a- 9. input signals, basic display colors and gray scale of each color colors & data signal gray scale gray scale r0 r1 r2 r3 r4 r5 g0 g1 g2 g3 g4 g5 b0 b1 b2 b3 b4 b5 black - 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 blue - 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 green - 0 0 0 0 0 0 1 1 1 1 1 1 0 0 0 0 0 0 cyan - 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 red - 1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 magenta - 1 1 1 1 1 1 0 0 0 0 0 0 1 1 1 1 1 1 yellow - 1 1 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 white - 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 black gs0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 gs1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 darker gs2 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ? brighter gs61 1 0 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 ? gs62 0 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 red gs63 1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 black gs0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 gs1 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 darker gs2 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 ? brighter gs61 0 0 0 0 0 0 1 0 1 1 1 1 0 0 0 0 0 0 ? gs62 0 0 0 0 0 0 0 1 1 1 1 1 0 0 0 0 0 0 green gs63 0 0 0 0 0 0 1 1 1 1 1 1 0 0 0 0 0 0 black gs0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 gs1 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 darker gs2 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 ? brighter gs61 0 0 0 0 0 0 0 0 0 0 0 0 1 0 1 1 1 1 ? gs62 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 blue gs63 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 0 :low level voltage, 1 : high level voltage each basic color can be displayed in 64 gray scales from 6 bit data signals. according to the combination of total 18 bit data signals, the 262,144-color display can be achieved on the screen. basic color gray scale of red gray scale of green gray scale of blue ld18203a- 10. optical characteristics ta=25 o c, vcc=+3.3v parameter symbol condition min. typ. max. unit remark viewing horizontal e 21, e 22 cr>10 60 70 - deg.
