Abstract: A curved human interface device is manufactured by thermoforming a stack. The stack comprises a front substrate formed of a transparent, first thermoplastic material; an OLED display configured to display an image through the front substrate; and a thermomechanical buffer layer formed of a transparent, second thermoplastic material arranged between the front substrate and the OLED display. Heat is applied to the stack for causing a temperature of the front substrate and buffer layer to increase to a respective processing temperature at which the first and second thermoplastic materials become pliable. The stack is thermoformed while the thermoplastic materials are pliable to form the curved human interface device. The second thermoplastic material has a lower stiffness at the respective processing temperature than the first thermoplastic material.

Abstract: Illuminating sections of a light guide with LEDs leads to unwanted light bleeding to other parts of the light guide. Furthermore typically LEDs are placed at a large distance from the area that couples out light from this LED due to a spike in intensity close to the LED. In order to avoid this spike being visible in the lit area the distance is increased which results in unwanted areal increase of the overall system. The present provides a layout to overcome these challenges.
