GENERAL DESCRIPTION Introduction This specification describes the interface requirements and features of a 2 line Liquid Crystal Display (LCD) , 15 characters wide. The characters are formed using a 8x18 dot matrix. Application This unit may be used as a console display which provides alphanumeric information that is easily readable in high ambient light or with the backlight in low light conditions. -

Page 5: Theory Of Operation
THEORY OF OPERATION Liquid Crystal Displays utilize ambient light falling on the display to reflect the image to the observer. The LCD cell is constructed by sandwiching a liquid crystal mixture between two glass plates that are coated with a polarizer, and lined with transparent electrodes. A selectively applied electric field aligns the nematic molecules (crystals) so that they either transmit or block the polarized light from being reflected back out of the cell to the viewer. -

User Defined Character Loading (5 x 8 Dot Matrix) A maximum of eight characters may be created temporarily (until power-off or reset) by a user-defined down- loaded character pattern. To do so, enter the following sequence of commands and data: BYTE 6-10 *Repeat bytes 6-10 for the number of characters to be downloaded. -

Dedicated Hardware Lines Not available. Serial Data and Self-test Serial characters are received with data formatted as a 10-bit word. The command set is structured to allow transmission of 8 data bits. The data rate is fixed at 9600 baud. The level is EIA-232C. (EIA-232) +15 TO +3V -15 TO -3V... -
Page 16: Electrical Characteristics
ELECTRICAL CHARACTERISTICS Power ON / OFF Sequence There are no deleterious effects associated with power ON and OFF of this display; however, rapid ON/OFF sequencing is not recommended. Neither data nor power connectors should be connected/disconnected while power is applied. Because of the power-up cycle within the microprocessor, rise time of the power supply should be less than 100mS. -
