Abstract
An illuminated touch sensitive surface module includes a sensor, an illuminated device and a controller. The sensor senses position information of hovering or touching objects, the illuminated device includes illuminated modes and one or more light guide films with characters, symbols or patterns, and the controller connects to the sensor and the illuminated device for controlling the illuminated modes of the illuminated device and the illumination of the light sources according to the position information.
Claims20
An illuminated touch sensitive surface module, comprising:
- a sensor;
- an illuminated device having a plurality of light guide films and light sources, each of the light guide films including a bottom and a light emitted out side for receiving the light beams of the light sources, wherein at least one micro member changing the paths of entered light beams toward the light emitted out side is set on the bottom;
- and
- a controller, connected to the illuminated device, switches the light sources, determines the entered light guild film and switches different illuminated modes of the illuminated touch sensitive surface module accordingly;
- wherein the sensor and the illuminated device are stacked mutually.
An illuminated touch sensitive surface module, comprising:
- a cosmetic layer disposed a masking material with a preset masking ratio;
- a sensor;
- an illuminated device having a light guide film, a plurality of light sources and a plurality of sub-regions;
- a bottom of the light guide film including a plurality of micro members for receiving the light beams of the light sources, wherein the micro members are responsive to the sub-regions for changing the paths of the light beams inside the light guide film toward the cosmetic layer and then providing an illuminated mode of the illuminated device;
- and
- a controller, connected to the illuminated device, adjusts the light sources to activate the higher illumination of parts of the sub-regions and to lower the illumination of the remained sub-regions than the preset masking ratio;
- wherein the cosmetic layer, the sensor and the illuminated device are stacked.
An electronic device, comprising:
- a housing;
- and
- an illuminated touch sensitive surface module set inside the housing, further comprising:
- a sensor;
- an illuminated device having a plurality of light guide films and light sources, each of the light guide films including a bottom and a light emitted out side for receiving the light beams of the light sources, wherein at least one micro member changing the paths of entered light beams toward the light emitted out side is set on the bottom;
- and
- a controller, connected to the illuminated device, switches the light sources, determines the entered light guild film and switches different operating modes of the illuminated touch sensitive surface module accordingly;
- wherein the sensor and the illuminated device are stacked mutually.
