Graphic LCD display module, COB type (Chip On Board) WG12864E1-TMI-V#N from Winstar Co. with 128×64 resolution, blue background color and white content. LCD matrix is a negative STN with transmissive polarizer. The display allows the use of 6800 interface. The module has NT7107/NT7108 controller. Uses 5V power supply.
This module can operate in a stable and failure-free way for a long period within wide range of temperatures. Thanks to such option, it may be successfully applied e.g. in transportation and automotive industry.
Inbuilt voltage generator
Apart from controller’s logic voltage supply, to obtain a suitable contrast the display requires an additional voltage. Thanks to an inbuilt voltage generator, there is no need to supply the display with outer voltage.
