DESCRIPTION 4/33 NL10276AC30-04L is a TFT (thin film transistor) active matrix color liquid crystal display (LCD) comprising amorphous silicon TFT attached to each signal electrode, a driving circuit and a backlight. NL10276AC30-04L has a built-in backlight with an inverter. The 38cm(15 Type) diagonal display area contains 1024x768 pixels and can display 262144 colors simultaneously. 2. FEATURES TMDS interface (SiI851, Silicon Image, Inc.) Wide viewing angle (with Retardation Film) Expansion functions Corresponding to DDC2B High luminance and Low reflection High contrast Luminance control (variable steps and two steps) Incorporated edge type backlight Replaceable lamp holders Replaceable inverter Approved by UL1950 Third Edition (File No. E170632) and CSA-C22.2 No.950-95 (File No. E170632) 3. APPLICATION PC monitor 4. STRUCTURE AND FUNCTIONS A color TFT (thin film transistor) LCD module is comprised of a TFT liquid crystal panel structure, LSIs for driving the TFT array, and a backlight assembly. Sandwiching liquid crystal material in the narrow gap between a TFT array glass substrate and a color filter glass substrate creates the TFT panel structure. And the driver LSIs are connected to the panel, the backlight assembly is attached to the backside of the panel. RGB (red, green, blue) data signals from a source system are modulated into a form suitable for active matrix addressing by the onboard signal processor and sent to the driver LSIs which in turn addresses the individual TFT cells. Acting as an Electro-optical switch, each TFT cell regulates light transmission from the backlight assembly when activated by the data source. By regulating the amount of light passing through the array of red, green, and blue dots, color images are created with clarity. NEC Corporation DOD-H-8237 5.

Luminance can be controlled by the duty value of input signal for BRTP. Duty=100%: luminance is maximum. Duty=20%: luminance is minimum. BRTC must not fix on "L" in the condition of PWSEL= "L" and BRTC ="H" or "Open". Otherwise, the inverter stops. In this case, even if BRTP pulse is input again, the backlight will not turn on.

For example, VGA signal has 640x480 pixels. But, if the display data can expanded to 1.6 times vertically and horizontally, VGA screen image can be displayed fully on the screen of XGA resolution. This LCD module has the function that expands vertical direction as shown in 7.9 (1). And expanding horizontal direction is possible by setting input CLK frequency equivalent to the magnification. It is necessary to make this CLK outside of this LCD module. Please adopt this mode after evaluating display quality, because the appearance in expansion mode is happened to be relatively bad in some cases. The followings show display magnifications for each mode.

Input signal timing: 15.Input signal timings (1) XGA mode, Typ. value 50cm Photo-detector: BM-5A(TOPCON) 1 LCD module Note2: The contrast ratio is calculated by using the following formula. Luminance with all pixels in white Contrast ratio (CR) = Luminance with all pixels in black NEC Corporation DOD-H-8237 Note3: Viewing angle isx = 0, y = 0 and at center. Note4: Definitions of viewing angle are as follows Perpendicular xLeft yy+ 12 o'clock Up x+ 26/33 Down Right Note 6: Definitions of response time are as follows. Photo-detector output signal is measured when the luminance changes "white" to "black" or "black" to "white". Response time is the time between 10% and 100% of the photo-detector output amplitude. 100% 90% White Luminance Black 10% 0% Ton Toff NEC Corporation DOD-H-8237 Note7: Luminance uniformity is calculated by using the following formula. Maximum luminance Luminance uniformity = Minimum luminance The luminance is measured at near the five points shown below. Column 171 512 853 27/33 Row 128 384 640 NEC Corporation DOD-H-8237 18.

ESTIMATED LIFE-TIME OF THE BARE LAMP Note 1,3 Conditions Bare lamp Luminance Maximum Room temp.252, Continuous operation value 40,000h ( IL=6.0mArms) Estimated Note 2 (MTTF) Criteria Half value luminance (compared with initial value.) Note1: The life-time is estimated value (reference). Note2: This estimated value is based on the test results with a bare lamp operation. The MTTF for the module may be different from these values, because of the influence of ambient and clamshell conditions. Note3: The life-time becomes short if the module is operated under the low temperature environment. Note4: This module consists of two lamps. Even though one of the lamps goes off, all the lamps may go off. NEC Corporation DOD-H-8237 29/33 20. GENERAL CAUTIONS Because the following statements are very important, please be sure you understand their contents completely. This figure is a warning that you will get hurt and/or the module will be damaged if you make a mistake in operation. ! CAUTION This figure is a warning that you will get an electric shock if you make a mistake in operation. This figure is a warning that you will get hurt if you make a mistake in operation. ! CAUTIONS Do not touch an inverter on which there is a caution label is stuck while the LCD module is in operation, because of dangerous high voltage. (1) Caution when taking out the module Pick up the pouch only, when removing the module from a carrier box. (2) Cautions for handling the module As the electrostatic discharges may break the LCD module, handle the LCD module with care against electrostatic discharges. Peel protection sheet out from the LCD panel surface as slowly as possible. As the LCD panel and backlight element are made from fragile glass material, impulse and pressure to the LCD module should be avoided. As the surface of polarizer is very soft and easily scratched, use a soft dry cloth without chemicals for cleaning. Do not pull the interface connectors in or out while the LCD module is operating. Put the module display side down on a flat horizontal plane. Handle connectors and cables with care. When the module is operating, do not lose CLK, Hsync, or Vsync signal. If any one or more of these signals is lost, the LCD panel would be damaged. The torque for mounting screws should never exceed 0.392 N*m. Don't push or rub the surface of LCD module please. If you do, the scratches or the marks like rubbing marks may be left on the surface of the module. Do not give the stress too much on interface connectors. The module may become function deficiency by a contact defective and damages. Pay attention to handling at the time of matching connector connection and in the connection condition. Do not put front side (display surface side ) of the module on a desk or a table for a long time, because the display may become un-uniformity. NEC Corporation DOD-H-8237 30/33 (3) Cautions regarding atmosphere Dew-drop atmosphere must be avoided. Do not store and/or operate the LCD module in a high-temperature and/or high-humidity atmosphere. Storage in an anti-static pouch and under the room temperature atmosphere is recommended. This module uses cold cathode fluorescent lamps. Therefore the lifetime of lamps is shortened if the module is operated under the low temperature environment. Do not operate the LCD module in high magnetic field. (4) Cautions about the module characteristics Do not apply any fixed pattern data for a long time to the LCD module. It may cause image sticking. Use screen savers if the display pattern is fixed. This module has the lends sheet which may cause the variation of the color hue in the different viewing angles. The ununiformity may appear on the screen under the high temperature operation. The light vertical stripe may be observed depending on the display pattern. This is not defects or malfunctions. The noise from the inverter circuit may observed in the luminance control mode. This is not defects or malfunctions. (5) Other cautions Do not disassemble and/or reassemble the LCD module. Do not readjust variable resistors nor switches in the module. When returning the module for repair, etc., please pack the module properly to avoid any damages. NEC recommends using original shipping packages. The liquid crystal display has the following specific characteristics. These are not defects or malfunctions. The optical characteristics of this module may be affected by the ambient temperature. This module has cold cathode tube for backlight. Optical characteristics, like luminance or uniformity, will be changed by the progress in time. Uneven brightness and/or small spots may be observed depending on different display patterns.
