Spectrum Displays designs and develops direct and edge light LED backlight systems with our custom LCD TFT arrays. A bright white LED is typically used during day mode or during high ambient lighting conditions. This type of backlight in combination with an optical front stack provides an adequate brightness level for the assembly to meet the requirements of sunlight readability as defined in MIL-L-85762A. The LED configuration we offer not only provides excellent luminosity uniformity, it also provides excellent redundancy for increased long-term reliability.
We work in partnership with our customer’s product designers to fully understand the requirements and deliver custom display solutions that meet the criteria with complete electronic 3D design, development, and support capabilities located within our organization; we can provide you with a completely integrated, custom display solution that meets your needs quickly and effectively.
Options such as temperature sensors to monitor and control heater assemblies and LED backlight power, and optical sensors to monitor backlight light output over the life of the product are also available.
Custom design TFT glass in addition to defining bezel sizes, LED backlight assembly, and optical films to enhance performance, the TFT display modules can also be integrated with customer-defined interface circuitry and peripherals such as display controllers, LED DC/DC converters for backlight and power supplies, as well as additional electronic circuitry design requirements.
Custom LED Design
Advancement in LED technology allows for a more suitable form of lighting in most rugged environments for many reasons. LED lights are extremely durable in a wide temperature range. LED lights not only generate less heat our designs dissipate most of the heat transfer via convection into a heat sink and circuit board. This characteristic allows rugged LED backlight systems used in highly bright LCD display systems. Bright LED backlight systems developed use a heat sink to transport thermal energy away from critical areas increasing the LED effective life in the application. We use an extended color and RGB LED backlights to provide rich colors in the finished display product. With the RGB LED type of backlight system it is possible to produce sharp spectral peaks of color and when combined with the LCD panel filters result in a larger gamut. This color can be adjusted for use in applications where displays used side by side need to have the same colors and look to the end user.
