LP141E2 liquid crystal display product specification ver 1. 4 nov 10 , 2000 page 1 /8 1. general description the LP141E2 - a1 is a color active matrix liquid crystal display with an integral cold cathode fluorescent lamp(ccf l ) backlight system. the matrix employs a - si thin film transistor as the active element. it is a transmis s ive type dis play operating in the normally white mode. this tft - lcd has a 14.1 inch es diagonally measured active display area with sxga+ resolution (1050 vertical by 1400 horizontal pixel array). each pixel is divided into red, green and blue sub - pixels or dots whic h 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 LP141E2 - a1 has been designed to apply the inter face method that enables low power, high speed , low emi. flat link must be used as a lvds(low voltage differential signaling) chip. the LP141E2 - a1 is intended to support applications where thin thickness, low power are critical factors and graphic display s are important. in combination with the vertical arrangement of the sub - pixels, the LP141E2 - a1 characteristics provide an excellent flat panel display for office automation products such as notebook pc. general fea tures active screen size 14.1 inches( 35.7 cm) diagonal outline dimensions 298.5 (h) 227.0 (v) mm (typ . ) , 6.0 (d) mm (max.) pixel pitch 0. 204 mm 0. 204 mm pixel format 1 400 horiz. b y 1050 ver t. pixels rgb stripe arrangement color depth 6 - bit, 262,144 colors luminance,white 185 cd/m 2 ( t yp . ) power consumption 1.32w typ.

LP141E2 liquid crystal display product specification ver 1. 4 nov 10 , 2000 page 2 /8 2 . electrical specifications 2 - 1. electrical characteristics the LP141E2 - a1 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 inver ter is an external unit to the lcd. table 1 electrical characteristics: parameter symbol values units notes min. typ. max. module: power supply input voltage power supply input current differential impedance power consumption rush current (i 2 t ) lamp operating voltage operating current established starting voltage at 25 c at 0 c operating frequency discharge stabilization time power consumption life time (at 25 c) v cc i cc zm p c v bl i bl f bl t s p bl 3.0 - 90 - - 680 3.0 - - 4 5 - 10,000 3.3 0. 400 100 1.32 - 725 5.0 - - 60 3. 63 15,000 3.6 0. 450 110 1.50 10 850 6 .0 1 100 1 450 80 3 4.08 - vdc a ohm watts % v rms ma v rms v rms khz minutes watts hrs 1 2 1 3 4 5 6 7 8 9 notes: 1 . the specified current and power consumption are under the vcc = 3.3v , 25 c , fv = 5 0hz condition whereas black pattern is displayed. 2. this impedance value is needed to proper display and measured form lvds tx to the mating connector. 3. littel fuse guarantees 100,000 pulses(inrush current), if i 2 t is less than 22%. 4. the variance of the voltage is + - 10%. 5. the transformer output voltage in the inverter must be high considering to the loss of the ballast capacitor in the inverter. the voltage above vs should be applied to the lamps for more than 1second for start - up. otherwise, the lamps may not be turned on. 6 . the output of the inverter must have symmetrical(negative and positive) voltage waveform and symmetrical cu rrent waveform.(unsymmetrical ratio is less than 10%) please do not use the inverter which has unsymmetrical voltage and unsymmetrical current and spike wave. lamp frequency may produce interference with horizontal synchronous frequency and as a resul t this may cause beat on the display. therefore lamp frequency shall be as away as possible from the horizontal synchronous frequency and from its harmonics in order to prevent interference. 7.let?s define the brightness of the lamp after being l ighted 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%. 8. the lamp power consumption shown above does not include loss of external inverter. 9 . 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 25 + - 2 c .
