Abstract

A touch input system including a stylus and a display device is provided. The stylus includes a battery module, a touch portion, a transducer module and a RF transmitting module. When a contact pressure is acted on the touch portion, the touch portion is electrically connected to the battery module by the contact pressure and emits a light signal. The display region receives and reacts to the light signal, and the contact pressure is transformed into an electrical signal by the transducer module. The RF transmitting module is electrically connected to the transducer module and transmitting the electrical signal. The display device includes a display region and a RF receiving module.

Claims (17)

1. A light emitting glove for touch input, comprising:

a glove, including an outer layer and an inner layer, and having a plurality of finger portions;

a control circuit board, disposed between the outer layer and the inner layer;

a plurality of light emitting elements, disposed on fingertips of the finger portions respectively, wherein a micro switch assembly is disposed on each of the light emitting elements; and

a plurality of connecting wires, disposed between the outer layer and the inner layer, wherein the light emitting elements are electrically connected to the control circuit board by the connecting wires respectively, and the light emitting element is driven to emit a light signal when its corresponding micro switch assembly is pressed on an operation surface of a display region within a touch input device.

2. The light emitting glove as claimed in claim 1 , further comprising:

a battery, disposed on the control circuit board.

3. The light emitting glove as claimed in claim 1 , further comprising:

a plurality of rubber layers, covering the ends of the finger portions respectively.

4. The light emitting glove as claimed in claim 3 , wherein each of the rubber layers has at least one heat dissipation opening.

5. The light emitting glove as claimed in claim 1 , wherein each of the connecting wires has a plurality of curled portions for being flexible.

6. The light emitting glove as claimed in claim 5 , wherein each of the curled portions is flattened between the outer layer and the inner layer.

7. The light emitting glove as claimed in claim 1 , wherein the light emitting element is a light emitting diode.

8. The light emitting glove as claimed in claim 1 , wherein the touch input device further comprising:

a light sensor array, arranged in a pixel electrode array of the display region.

9. The light emitting glove as claimed in claim 8 , wherein the light signal is suitable for actuating at least one light sensor of the light sensor array.

10. The light emitting glove as claimed in claim 1 , wherein the light signal is used to locate a touch position when pressed on the operation surface of the display region.
