Abstract
A vehicle display configuration includes an LED (light emitting diode) display with a flexible circuit board and a plurality of LEDs mounted on the flexible circuit board. The flexible circuit board conforms to the surface shape of a mounting layer to which it is fastened. A control circuit which includes a driver circuit is operatively connected to the LEDs for controlling the LEDs. The driver circuit has a serial data input and a shift register. The driver circuit shifts data received via the serial data input into the shift register and controls the LEDs in accordance with the data in the shift register. A method of controlling a display is also provided.
Claims14
A vehicle display configuration, comprising:
- a mounting layer having a surface shape;
- an LED display including a flexible circuit board and a plurality of LEDs mounted on said flexible circuit board;
- said flexible circuit board conforming to said surface shape of said mounting layer;
- a control circuit including a driver circuit operatively connected to said LEDs for controlling said LEDs;
- said driver circuit having a serial data input and a shift register, said driver circuit shifting data received via said serial data input into said shift register;
- and
- said driver circuit controlling said LEDs in accordance with the data in said shift register.
A method of controlling a display, the method which comprises:
- providing cycle periods and controlling an LED by switching the LED at each cycle period selectively into an on-state and an off-state;
- providing N bits for controlling the on-state and the off-state of the LED, N being an integer greater than 2;
- controlling the on-state and the off-state of the LED by repeatedly performing steps a) and b) starting with n=1 and increasing n by 1 until n=N:
- a) selectively switching the LED into an on-state and an off-state in accordance with an n−th one of the N bits;
- and
- b) waiting for a time period corresponding to 2n−1 cycle periods.
