Monochrome Character Modules
For products that require the use of alpha or numeric characters on the display, a monochrome character module can be built to fit product requirements. Monochrome character LCD modules are available in black and white and can be designed to meet any backlight color requirement. Changing the backlight color gives an added effect to the display, making it look as though it utilizes colored numbers.
The backlight can be changed to a variety of colors, using the Red/Green/Blue (RGB) scheme, to mix and create the necessary color for the background. Emergency vehicles, for example, utilize red whereas other products, such as HVAC systems, choose colors such as blue so it is not harsh during the night hours in people’s homes.
Ocular has standard character LCD modules available with set lines and characters required. However, Ocular also has the expertise to build custom character LCD modules if required.
Character modules can be built as Twisted Nematic (TN) or Super Twisted Nematic (STN) displays. Twisted Nematic displays are very cost effective but have limited multiplex ratios available. If additional ratios are required, STN displays are available as well. The STN displays can also be used for larger size requirements, offering moderate response times.
Since Ocular has been providing LCD solutions for over two decades, a robust portfolio of standard products is available. Ocular also provides customizable options, consulting services and a full suite of engineering services including electronic design, mechanical design, industrial design, PCB design and firmware development. Ocular’s design team has developed numerous capabilities including anti-reflective glass bonding for TFT displays that are readable in direct sunlight, high brightness LCD backlighting systems, heater-bonded LCD for systems that must operate at extremely low temperatures, shock-mounted LCDs and encapsulated LCDs for harsh environmental operating applications.
