5-Inch TOPPAN Blanview™ Display - Sunlight-Readable LCD Without Backlight Modification
Clear Visibility Indoors and Outdoors from a Single Display Solution
Designing products that must perform reliably in both indoor and outdoor environments has long required a difficult choice: accept reduced readability under bright sunlight, increase backlight power to compensate – adding heat, power draw, and battery load - or maintain two separate product variants for different deployment scenarios.
TOPPAN's Blanview™ semi-transflective LCD technology resolves this trade-off at the panel level. Rather than simply driving more light through the display from behind, Blanview™ panels combine transmissive and reflective characteristics, using ambient light itself to enhance image brightness and contrast. The result is a display that performs significantly better in high-ambient-light conditions than a conventional transmissive LCD - using the same backlight unit and without any modification to the existing hardware.
FORTEC Switzerland now offers the 5-inch TOPPAN Blanview™ display solution, available for integration into customer designs across a broad range of applications.
2× Brightness and 1.5× Contrast - Same Backlight, No Hardware Changes
When paired with the identical backlight unit used in a standard transmissive LCD, the 5-inch Blanview™ panel achieves twice the effective brightness and a 1.5× higher contrast ratio. Under direct sunlight at up to 100,000 lux - the intensity of full midday sun - the display maintains clear, legible output with no screen wash-out. As lighting conditions change rapidly, from shadow to bright sunlight and back, readability remains consistent without any dynamic adjustment required from the system.
For product designers, this means that a display previously specified for indoor use can be carried directly into outdoor deployment without hardware redesign. The existing backlight driver, power supply, and mechanical integration remain unchanged.
System-Level Benefits Beyond Display Performance
The advantages of the Blanview™ approach extend beyond what the panel itself displays: Lower thermal load: because the display achieves its brightness advantage through reflective light utilisation rather than increased backlight power, heat generation within the host device is reduced. This directly improves overall system reliability and can extend the service life of the end device.
Lower power requirements: reduced reliance on backlight output to achieve outdoor-readable brightness translates into lower current draw from the power source. For battery-powered products, this enables smaller-capacity battery designs and reduces total bill-of-materials cost - a meaningful advantage in portable instrumentation, handheld HMIs, and field devices.
Simplified product portfolio: a single validated display solution covers both indoor and outdoor deployment scenarios. This consolidates product design effort, simplifies inventory management, and reduces the number of distinct SKUs required to serve multi-environment product families.
Target Applications
The 5-inch Blanview™ display is suited for a wide range of embedded and portable applications where sunlight readability is a requirement:
- Handheld HMIs and industrial controllers
- Outdoor kiosks and self-service payment terminals
- Marine navigation and vessel dashboard systems
- Portable medical equipment
- Battery-powered field test instruments
- Other sunlight-exposed embedded devices
