STYLUS AND TOUCH INPUT SYSTEM
First Claim
1. A touch input system, comprising:
- a stylus, comprising;
a main body;
a battery module, disposed at the main body;
a touch portion, disposed at the main body, wherein 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 continuously;
a transducer module, disposed at the main body, wherein the contact pressure is transformed into an electrical signal by the transducer module, and the electrical signal is directly proportional to the contact pressure; and
a RF transmitting module, disposed at the main body, electrically connected to the transducer module, and transmitting the electrical signal; and
a display device, comprising;
a display region, receiving and reacting to the light signal; and
a RF receiving module, electrically connected to the display region and detecting the electrical signal within a predetermined frequency range, wherein the electrical signal is used to determine the spacing between the touch portion and the display region.

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.

9. A stylus, comprising:
-
a housing, has a front end, a back end opposite to the front end and an opening formed at the front end; a battery module, disposed in the housing and having a blocking plate facing the front end; a touch portion, sliding disposed at the opening along an axis, wherein the touch portion is suitable for contacting a operation surface to move into the housing; a detector, fixed to the blocking plate and suitable for detecting a motion of the touch portion to obtain an analog signal; and an elastic element, disposed between the blocking plate and the touch portion and located on the axis, wherein when the touch portion contacts the operation surface to move into the housing, the elastic element is compressed between the blocking plate and the touch portion, such that touch portion is electrically connected to the battery module and emits a light signal continuously, when the touch portion is distant from the operation surface, the touch portion is recovered by an elastic force of the elastic element, such that the electrical connection between the touch portion and the battery module is terminated. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A stylus, comprising:
-
a pipe, having a front end, a back end opposite to the front end and an opening formed at the front end, wherein a diameter of the opening is smaller than a diameter of the pipe; a touch portion, sliding disposed at the opening, wherein at least a part of the touch portion is located in the pipe; a first magnetic element, disposed in the pipe and having a through hole, wherein a diameter of the through hole is larger or substantially equal to the diameter of the opening; and a second magnetic element, fixed to the touch portion located in the pipe, wherein the first magnetic element is located between the second magnetic element and the opening, the touch portion is passed through the through hole, and when the touch portion is driven to move toward the back end by a force resisting a magnetic attractive force generated between the first magnetic element and the second magnetic element, the second magnetic element is driven to move away from the first magnetic element. - View Dependent Claims (18, 19, 20)
