Philips LCD Co. The matrix employs a-Si Thin Film Transistor as the active element. It is a transmissive type display operating in the normally white mode. It has a 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 8-bit gray scale signal for each dot, thus, presenting a palette of more than 16M colors. It has been designed to apply the 8-bit 1 port LVDS interface.

It is intended to support applications where high brightness, super wide viewing angle, high color saturation, and high color are important.

By vert. Absolute Maximum Ratings The following are maximum values which, if exceeded, may cause faulty operation or damage to the unit. Table 1. Temperature and relative humidity range are shown in the figure below. Wet bulb temperature should be 39 C Max, and no condensation of water. Electrical Specifications Electrical Characteristics It requires two power inputs.

The second input power for the CCFL, is typically generated by an inverter. The inverter is an ex ternal unit to the LCDs. The current is specified at the maximum current pattern. The duration of rush current is about 2ms and rising time of power Input is 1ms min. So all the parameters of an inverter should be carefully designed so as not to produce too much leakage current from high-voltage output of the inverter.

When you design or order the inverter, please make sure unwanted lighting caused by the mismatch of the lamp and the inverter no lighting, flicker, etc never occurs. When you confirm it, the LCD— Assembly should be operated in the same condition as installed in you instrument.

Do not attach a conducting tape to lamp connecting wire. Because leakage current is occurred between lamp wire and conducting tape.

Specified values are for a single lamp. The voltage above VS should be applied to the lamps for more than 1 second for start-up.

Inverter open voltage must be more than lamp starting voltage. Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current. Lamp frequency may produce interface with horizontal synchronous frequency and as a result this may cause beat on the display.

Therefore lamp frequency shall be as away possible from the horizontal synchronous frequency and from its harmonics in order to prevent interference. The lamp power consumption shown above does not include loss of external inverter.

Please do not use the inverter which has unsymmetrical voltage and unsymmetrical current and spike wave. Requirements for a system inverter design, which is intended to have a better display performance, a better power efficiency and a more reliable lamp, are following.

It shall help increase the lamp lifetime and reduce leakage current. The inverter which is combined with this LCM, is highly recommended to connect coupling ballast condenser at the high voltage output side. When you use the inverter which has not coupling ballast condenser, it may cause abnormal lamp lighting because of biased mercury as time goes. In case of edgy type back light with over 4 parallel lamps, input current and voltage wave form should be synchronized Ver.

All VLCD power input pins should be connected together. EN Red6 Notes : 1. The mating connector part number is SM02 8. The pin configuration for the connector is s hown in the table below.

Table 7. If the value is odd number times of tCLK , display control signal can be asynchronous. Vsync and Hsync should be keep the above specification. Signal Timing Waveforms 0. Color Data Reference The Brightness of each primary color red,green,blue is based on the 8-bit gray scale data input for the color; the higher the binary input, the brighter the color.

The table below provides a reference for color versus data input. Table 8. Please avoid floating state of interface signal at invalid period. Lamp power must be turn on after power supply for LCD an interface signal are valid.

Surface luminance is luminance value at center point 1 across the LCD surface 50cm from the surface with all pixels displaying white. For more information see FIG 2. For additional information see FIG 3. Viewing angle is the angle at which the contrast ratio is greater than The angles are determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which is normal to the LCD surface.

For more information see FIG 4. Gray scale specification Gamma Value is approximately 2. For more information see Table Table L Jun. Mechanical Characteristics The contents provide general mechanical characteristics. In addition the figures in the next page are detailed mechanical drawing of the LCD. International Standards Packing Serial No Serial No. The label is attached to the backside of the LCD module. This is subject to change without prior notice. Twisted stress is not applied to the module.

And the case on which a module is mounted should have sufficient strength so that external force is not transmitted directly to the module. Transparent protective plate should have sufficient strength in order to the resist external force. And please do not rub with dust clothes with chemical treatment.

Do not touch the surface of polarizer for bare hand or greasy cloth. Some cosmetics are detrimental to the polarizer. Do not use acetone, toluene and alcohol because they cause chemical damage to the polarizer.

Their long time contact with polarizer causes deformations and color fading. In lower temperature, it becomes longer. In lower temperature, it becomes lower.

And in lower temperature, response time required time that brightness is stable after turned on becomes longer. Condensation makes damage to polarizer or electrical contacted parts. And after fading condensation, smear or spot will occur. Sufficient suppression to the electromagnetic interference shall be done by system manufacturers.

Grounding and shielding methods may be important to minimized the interference. Otherwise, LCM can not be operated its full characteristics perfectly.

Make certain that treatment persons are connected to ground through wrist band etc. Do not expose the module to sunlight or fluorescent light. Keep the temperature between 5 C and 35 C at normal humidity. It is recommended that they be stored in the container in which they were shipped. When the protection film is peeled off, static electricity is generated between the film and polarizer. This should be peeled off slowly and carefully by people who are electrically grounded and with well ion-blown equipment or in such a condition, etc.

When the glue remains on the bezel surface or its vestige is recognized, please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normal-hexane.
