revision ver 1.0 october 14, 1998 page 4 /25 LM151X2 liquid crystal display product specification general descriptions the lg philips lcd model LM151X2 lcd is a color active matrix liquid crystal display with an integral cold cathode fluorescent tube( ccft) back light system. the matrix employs a- si thin film transistor as the active element. it is a transmissive type display operating in the normally white mode. this tft- lcd has a 15.1 inch 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 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. LM151X2 has been designed to apply the cmos logic level interface. the LM151X2 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 LM151X2 characteristics provide an excellent flat panel display for office automation products such as monitors. general display characteristics the following are general features of the model LM151X2 lcd ; active display area 15.1 inches(38cm) diagonal outsize dimensions 352.6w * 265.0h * 18.5t( typ)mm ( w ithout inverter and user connector) pixel pitch 0.30 mm x 0.30 mm pixel format 1024 horiz. by 768 vert. pixels rgb vertical stripe arrangement color depth 6-bit, 262,144 colors display operating mode transmissive mode, normally white surface treatments hard coating(3h), anti-glare treatment of the front polarizer source driver circuit gate driver tft-lcd (1024 768) timing control block power block backlight ass?y cn1 connector cn2 cn3 al pha point lt d. p.o. b ox 41 00 75 1 he l sin ki , fi nl and h t t p : / / www . al ph a.f i t el.: + 35 8 - 9- 34 64 3 4 1 fa x : + 35 8 - 9 - 34 6 4 3 4 2

revision ver 1.0 october 14, 1998 page 17/25 LM151X2 liquid crystal display product specification 12. incoming inspection standards for tft-lcd modules 1. scope this incoming inspection standard shall be applied to tft-lcd modules(hereafter called ? lcms?) supplied by lg electronics inc.(hereafter called the ?supplier?) to customer. 2. incoming inspection the customer shall have the right to conduct at its own cost and expense, an incoming inspection of the lcms at the destination specified in the relevant bills of lading in accordance with the lcm?s specifications separately agreed upon and the inspection standard set forth in this article. the customer shall notify the supplier in writing of the inspection results(acceptance or rejection) in accordance with the said inspection standard within 40 days after the date of the bills of lading. should customer fail to so notify the supplier within the said 40 days period, the customer?s right to reject the lcms shall then lapse, and the said lcms shall be deemed to have been accepted by the customer. 3. method of incoming inspection unless otherwise agreed upon in writing, the sampling inspection method based on mil-std-105e shall be applied to the customer?s incoming inspection. 4. classification of defects defects are classified as either a major defect or a minor defect based on the degree of defect defined herein. a) major defect a major defect is a defect that is likely to result in product failure, or reduction in the product?s intended usage. b) minor defect a minor defect is a defect that has little bearing on the effective use or operation of the product. specific criteria of judgement of major and/or minor defects or other related issues shall be in accordance with the attached ?classification of defects?. ( refer to appendix 4) 5. acceptable quality level(? aql?) the aql for major and minor defects shall be respectively set forth below. a) major defects : aql = 0.65% b) minor defects : aql = 1.5% 6. sampling inspection method a) lot size : quantity per shipment lot b) sampling type : normal inspection, single sampling c) inspection level : ii d) sampling table : table in mil-std-105e 7. determination of acceptability and subsequent disposal if the number of defects found in the lcm sampling lot is equal to or less than the applicable acceptance level, the lot shall be accepted. if the number of defects is greater than the applicable acceptance level, the lot shall be rejected. the customer shall inform the supplier of the detailed results of such inspection within the time period stipulated in item #2 ?incoming inspection?. a) accepted lot an acceptance under the above incoming inspection shall constitute an acceptance by the customer of such lot of the lcms in terms of the landed quality thereof. b) rejected lot if a shipment lot of products is rejected under the above incoming inspection due to any defects for which the supplier is responsible and such a fact is clearly confirmed by the supplier through a separate inspection or as otherwise decided, the supplier shall choose one of the following three options which must be determined by mutual consent. the supplier shall advise the customer of its choice not later than 14 working days(monday to friday) of receipt of the ?customer?s notification of rejected lot? : -1. the customer shall return the rejected lot to the place to be designated by the supplier and the supplier shall screen all of the products in the lot and repair or replace the defective products. al pha point lt d. p.o. b ox 41 00 75 1 he l sin ki , fi nl and h t t p : / / www . al ph a.f i t el.: + 35 8 - 9- 34 64 3 4 1 fa x : + 35 8 - 9 - 34 6 4 3 4 2

(combination) ii) line defect all line defects such as vertical, horizontal or cross line defect are not allowed. note 1) dot defect : defected area > 1/2 dot 2) 1 dot : defect dot is isolated, not attached to other defect dot. 3) 3 join n dot : n dots are consecutive. (n means the number of defect dots) 9. other if any problems arise with the lcm supplied by lge, the customer and supplier will cooperate and make efforts to solve it with mutual confidence and respect. al pha point lt d. p.o. b ox 41 00 75 1 he l sin ki , fi nl and h t t p : / / www . al ph a.f i t el.: + 35 8 - 9- 34 64 3 4 1 fa x : + 35 8 - 9 - 34 6 4 3 4 2

revision ver 1.0 october 14, 1998 page 20/25 LM151X2 liquid crystal display product specification 15. precautions please pay attention to the followings when you use this tft-lcd module with back-light unit. 1 )you must mount module using mounting holes arranged in 4 corners. 2) be sure to turn off the power when connecting or disconnecting the circuit. 3) note that the polarizers are easily damaged. pay attention not to scratch or press this surface with any hard object. 4) when the lcd surface become dirty, please wipe it off with a soft material. ( ie. cotton ball) 5) protect the module from the esd as it may damage the electronic circuit (c- mos). make certain that treatment person?s body are grounded through wrist bend. 6) do not disassemble the module and be careful not to incur a mechanical shock that might occur during installation. it may cause permanent damage. 7) do not leave the module in high temperatures, particularly in areas of high humidity for a long time. 8) the module not be expose to the direct sunlight. 9) avoid contact with water as it may a short circuit within the module. 10) do not apply invalid signal, especially very high frequency data clock and h sync . invalid signal causes improper shutdown of dc/dc converter in lcm or permanent damage to lcd module. (if dc/dc converter in lcm is in shutdown state, lcm shows only white screen. then please turn off and on once lcm power.) 11) if the lcm displays the same pattern continuously for a long period of time, it can be the image sticking to the screen. al pha point lt d. p.o. b ox 41 00 75 1 he l sin ki , fi nl and h t t p : / / www . al ph a.f i t el.: + 35 8 - 9- 34 64 3 4 1 fa x : + 35 8 - 9 - 34 6 4 3 4 2
