  • Publication number: 20230247862
    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.

  • Publication number: 20220330433
    Abstract: An electronic component (1) is connected to a conductive track (2) on a flexible substrate (3). A connection layer (4) of a composition comprising a thermoplastic material (TPM1) is provided on the conductive track (2). The connection layer (4) has at least one cutout (5) aligned to overlap the conductive track (2). A thermosetting material (TSM1) in liquid state is used to fill the cutout (5). The electronic component (1) is provided on top of the connection layer (4). By applying heat, a temperature of the connection layer (4) is raised to above a softening temperature of the thermoplastic material (TPM1). Pressure is applied to form a mechanical connection. By the application of heat (H) a temperature of the thermosetting material (TSM1) is raised above its thermosetting temperature for olidifying the thermosetting material (TSM1) and forming an electrical connection (E).

  • Publication number: 20220287186
    Abstract: An electronic device (100) comprises an electronics substrate (10) with at least one light emitting device (12), a cover substrate (20) with a graphical pattern including at least one window (22), and a thermoplastic layer (30) there between. A multilayer laminate (40) of the device (100) is formed by combining the electronics substrate (10) and the cover substrate (20) by lamination with protruding electronic components (11,12) facing the thermoplastic layer (30). At least the thermoplastic layer (30) is heated to a lamination temperature (T1) for increasing a plasticity of the thermoplastic material (30m). The electronic components (11,12) are pushed by the lamination into the heated thermoplastic layer (30) for embedding the electronic components (11,12) in the thermoplastic material (30m).

  • Publication number: 20220015229
    Abstract: A curved electronic device (10c) can be formed by a stack with a curved substrate (13) comprising a thermoplastic material (Ms), and at least one electronic component (14) connected to an electronic circuit (15) disposed on the substrate (13). A component area (11) of the substrate surface (11.12) around the electronic component (14) comprises a first material (M1) providing relatively low absorption (A1) to light (L) and a surrounding area (12) of the substrate (13) outside the component area (11), comprises a second material (M2) providing relatively high absorption (A2) of the light (L). E.g. as a result of differential heating and thermoforming a first thickness (T1) of the substrate (13) in the component area (11) may be relatively high compared to a second thickness (T2) of the substrate (13) in the surrounding area (12).

  • Patent number: 11175445
    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.
