7 7 lm15 1x3 liquid crystal display product general specification ver 1.1 june 27,2000 page 1 /7 1. general description the LM151X3 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 display operating in the normally white mode. this tft - lcd has a 15.1 inch s diagonally measured active display area with xga resolution(768 vertical by 1024 horizontal pixel array). each pixel is divided into red, green and blue sub - pixels or dots which are arr anged 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 16,777,216 colors. the LM151X3 has been designed to apply the tmds interface method . the LM151X3 lcd is intended to support applications where high brightness, wide viewing angle, high color saturation, and high color depth are very important. in combination with the vertical arrangement of the sub - pixels, the LM151X3 characterist ics provide an excellent flat panel display for office automation products such as monitors. general features active screen size 15.1 inches( 307.2 x 230.4mm ) diagonal outl ine dimensions 352.0(h) ?? 263.5(v) ?? 1 6. 0 (d) mm (typ) without user connector pixel pitch 0.300 mm ?? 0. 300 mm pixel format 1024 horiz. by 768 vert. pixels rgb stripe arrangement color depth 8 - bit, 16,777,216 colors luminance,white 250 cd/m 2 (typ) power consumption 2.1watts logic / 9.7watts ccfl (typ. with 256 gray pattern) weight 1 5 00 g (typ) display operating mode transmissive mode, normally white surface treat ments hard coating(3h), anti - glare treatment of the front polarizer v sync power line for digital logic v cc (3.3v) analog power line for tft - lcd panel source driver circuit gate driver circuit tft - lcd panel (1024 768) timing control block backlight ass?y cn3 cn4 1024 1 1 768 tmds 4 pairs v dd (5v) panel link receiver dc/dc power block cn1 connector (20pin) h sync cn2 connector (14pin)
7 7 lm15 1x3 liquid crystal display product general specification ver 1.1 june 27,2000 page 2 /7 2 . electrical specifications 2 - 1. electrical characteristics the l m151x3 requires two power inputs. one is employed to power the lcd electronics and t o 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. table 1 electrical characteristics: parameter symbol values units notes min. typ. max . module: power supply input voltage power supply input current power consumption v cc v dd i cc i dd p c 3.15 4.5 0.20 0.20 - 3.3 5. 0 0.23 0.25 2.1 3.45 5.5 0.26 0.30 3.0 vdc vdc a a watts 1 1 lamp operating voltage operating current es tablished starting voltage at 25 ? at 0 ? operating frequency discharge stabilization time power consumption life time v bl i bl v bs f bl t s p bl 585(9ma) 3.0 - - 3 0 - - 30000 605(8ma) 8.0 - - 50 - 9.7 - 720(3ma) 9.0 1020 1430 60 3 10.6 - v rms ma v rms v rms khz minutes watts hrs 2 3 4 5 6 7 8marms notes: 1. the specified current and power consumption are under the v dd = 5.0v , v cc = 3.3v, 25 ? and fv = 60hz condition power suppl y input current and typ. power consumption is measured while 256 gray pattern is displayed the max. power consumption is measured while vertical 2line(full white) by 2line(full black) pattern is displayed. 2. the variance of the voltage is 10%. 3. 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. 4. 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 the inverter which has unsymmetrical voltage and unsymmetrical current and spike wave. lamp frequency may produce interferen ce with horizontal synchronous frequency and as a result 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 interfer ence. 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 not less than 95%. 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% compared to that of initial value at the typical lamp current on condition of continuous operating at 25 2 ? .
