Blanview is Toppan’s unique TFT-LCD technology enabling the display to create high contrast and crisp images even in bright circumstances where a sunlight hit to display surface directly.
With leveraging Toppan’s high-quality amorphous silicon technology “HAST”, which has been fostered in our 40-years-long display expertise, TOPPAN succeeded in generating new type TFT-LCD with a good balance between 2 values – Sunlight Readable and Low Power Consumption.
Transmissive
Transmissive-type is the most common LCD technology that is widely used in many electrical devices. Transmissive can provide clear images in indoor and dark situations, but meanwhile its display readability gets worse in bright outdoor situations. Backlight power increase can improve the display visibility somewhat, but it lead to boost total power consumption; this may be critical impact to battery-driven handheld devices.
Transflective
Transflective-type is suitable LCD technology to outdoor applications. Transflective has pixels divided into 2 areas, Transmission and Reflection area; the reflection area takes a role to reflect incident light from outside. This can give a clear display readability as well as low power consumption; however, the panel transmittance becomes rather lower due to a 2-divided pixel structure. As a result, Transflective inherently has a drawback of large power consumption in indoor or dark conditions. Complex pixel structure furthermore cause a problem that a color level changes indoors and outdoors.
Blanview
Toppan’s Blanview technology successfully overcomes drawbacks that Transmissive and Transflective-type TFT-LCDs have respectively.
-Good display readability in outdoors/bright environments
-Keeping low power consumption in any ambient luminance conditions
-High image quality in indoors/dark environments on the same level as Transmissive
-Less display performance variation between indoor and outdoor conditions
