New Transparent Electroluminescent Displays

Planar Systems, an Oregon-based company specializing in display solutions, has recently introduced its transparent and segment electroluminescent (TASEL) displays. These displays are based on an innovative technology that offers better transparency and the ability to cut or form the display into a variety of shapes. The new technology could have military applications as well as industrial applications in the consumer electronics’, automotive and aviation industries.

Planar Systens introduced its new displays last month, in custom forms and sizes with curved and moldable shapes. The company’s RoHS-compliant displays have 84%  transmission transparency, optional transparent or mirrored formats, and a 179° viewing angle. Other interesting features include an “instant on” response time of less than 1ms over the entire temperature spectrum, a glass-operating temperature range of -100 C – +۫ 100C, touch screens, performance films and other customization options. 

According to Planar, transparent displays are ideal for markets in which design and aesthetics are crucial components in communicating product innovation and quality. The company says its TASEL technology removes the constraints imposed by flat, rectangular, non-transparent displays. “Our innovative electroluminescent technology enables glass displays to be curved into different shapes and configurations, opening up markets with new OEM customers. Product designers seem inspired by this breakthrough to re-imagine how they incorporate displays into projects.” – said Doug Barnes, General Manager and Vice President of the Industrial Business Unit in Planar Systems

Electroluminescent Displays (EL) are created by sandwiching a thin layer of phosphorescent substance between two wired plates, in order to form a grid. When the electrical current passes through the horizontal and vertical wires, the phosphorescent film emits radiation in the form of light. EL display technology is particularly useful in applications that do not require immaculate full color, but where ruggedness, speed, high-contrast and a wide angle of vision are needed. Color technology for EL displays has advanced significantly over the last decade, especially for micro-displays. Additionally, there have been dramatic improvements in the brightness of the luminescent films and the development of drive schemes to extend display life. Planar says its products are used today by equipment and system designers, whose customers demand improved image quality, longer lifetime, and higher reliability displays.

Planar’s EL technology is widely used in transportation displays, with applications in fields such as vehicle routing, fleet communications and operational efficiency monitoring. The company says that due to the crispness, clarity and wide viewing angle of the display image they provide, their products have also been used by military forces to communicate information related to transportation, aviation, navigation and logistical applications, as well as for medical equipment purposes..
