The optical touch screen not only outputs images, but also receives commands, so it is more intuitive than the keyboard or mouse operating interface, and has the advantages of being on the go.

However, with the multi-touch on the optical touch screen for positioning, there are still problems in the notebook. For example, the optical touch screen is susceptible to environmental light sources. In addition, the notebook computer is lightweight and has a lightweight design of a thin panel. Therefore, when the user opens the notebook computer, the optical touch is used. The screen is easily deformed by the distortion of the panel when it is opened, which causes misjudgment in positioning. Therefore, the problem of the malfunction of the optical touch screen not only increases the difficulty of the operation of the user, but also limits the application range of the optical touch screen.

In the electronic device of the present invention, when the opening angle is greater than a predetermined angle and the first body has an instantaneous swing speed, the detecting unit suspends the optical touch module to perform the positioning function.

Secondly, the present invention further provides an electronic device, which can further sense whether the electronic device is in a standby state through the detecting unit, so as to save system resources.

According to still another electronic device of the present invention, the electronic device includes: a housing, a processing module, and a detecting unit.

The above description of the present invention is intended to be illustrative and illustrative of the spirit and principles of the invention, and to provide further explanation of the scope of the invention. The features, implementations, and utilities of the present invention are described in detail with reference to the preferred embodiments.

The "1A" and "1B" are an electronic device 100 according to an embodiment of the present invention, wherein the electronic device 100 can be a portable navigation device, a notebook computer, or a personal mobile phone or the like. The following description is based on the electronic device 100 as a notebook computer as a preferred embodiment. The electronic device 100 is not limited thereto. In other embodiments, it may be a portable navigation device, a personal mobile phone or the like. An electronic device using a touch screen panel.

The electronic device 100 includes a housing 102, an optical touch module 104 and a detecting unit 106. The housing 102 has a first body 10 and a second body 12, and the first body 10 and the second body 12 are pivotally connected to the pivot 14 in a rotatable relationship. The pivotal position of the first body 10 and the second body 12 is not limited to the bottom of the two bodies, and may be located at other positions to enable the first body 10 and the second body 12 to be relatively rotated. range. Here, the first body 10 is pivotally connected to the second body 12, and an opening angle θ ₁ , θ ₂ is formed between the first body 10 and the second body 12 .

The optical touch module 104 is disposed on a surface of the first body 10 with respect to the second body 12, wherein the optical touch module 104 can be an optical touch monitor (OTM) but not The optical touch screen can be an infrared type, an optical image recognition type, or an embedded optical touch screen. The optical touch module 104 mainly uses the light-emitting diodes located on the X-axis and the Y-axis above the screen to project light that is directed toward the edge of the opposite screen, and reflects the light-emitting diode by using a retro-reflecting plate. The light is used to detect the relative position of the indicator on the screen, wherein the light emitted by the LED can be infrared light, visible light, etc., and the light emitting diode can be an infrared light emitting diode or a visible light emitting diode Body and so on.

In other words, when an indicator (such as a pen tip or a finger) blocks the light emitted by the LED in the touch area, the optical touch screen can be controlled by the optical receiver and the internal computing control unit. The coordinates of the indicator are estimated to achieve the function of positioning. Since the cost of the light-emitting diode is not high, even if it is applied to a large-sized screen, it does not increase the production cost. Secondly, on the practical application level, the user does not need to pressurize when operating the optical touch screen, which can effectively reduce the touch damage of the screen.

In addition, the optical touch module 104 can also choose to replace the conventional reflective strip with a waveguide element. For example, the waveguide element has a material different from the outside air, and the light projected from the light-emitting diode can be restricted from being transmitted in the waveguide element by the refractive index of the waveguide element different from the outside air. Therefore, when the light emitting diodes are disposed at diagonal positions opposite to the light receivers, the waveguide elements may be respectively disposed on both sides of the touch area (such as a screen) adjacent to the light emitting diodes, and the waveguide The shape of the element may be a wedge-shaped structure that is thinner near one end of the light-emitting diode, or may be a flat plate structure.

By being limited to the light transmitted in the waveguide element and diverging and distributing in the touch area, the light receiver can be combined with the lens to increase the probability of receiving all the light in the touch area. Therefore, the optical touch module 104 can effectively resist the influence of the ambient light source, reduce the brightness of the light emitting diode, reduce the current loss, and increase the positioning accuracy of the optical touch module 104.

The detecting unit 106 is disposed on one side of the optical touch module 104 and can be used to detect the opening angle of the housing 102.

The acceleration of the horizontal (x-axis direction), vertical (y-axis direction) and longitudinal (z-axis direction) directions to estimate the angle of the opening. The position of the detecting unit 106 relative to the first body 10 can be embedded in the side of the optical touch module 104 or in the optical touch mode as shown in FIG. 2A to FIG. 2C. The periphery of group 104. For example, in order to enable the detecting unit 106 to more accurately sense the acceleration of the three sides, and to convert the value of the opening angle, the detecting unit 106 can be oppositely disposed on the frame of the optical touch module 104, and The detecting unit 106 can be a three-axis accelerometer.

As shown in FIG. 1A, when the detecting unit 106 detects that the opening angle θ _{1 is} less than a predetermined angle, the optical touch module 104 suspends its positioning function. Therefore, the optical touch module 104 can effectively avoid the misjudgment caused by the distortion of the screen backing plate when the user just turns on the electronic device 100.

As the user turns on the electronic device 100, as shown in FIG. 1B, so that the opening angle θ _{2 is} greater than the predetermined angle, the user may still cause the optical contact due to a momentary accidental touch or momentary pushing of the first body 10. The misjudgment of the control module 104. In order to avoid this problem, after the opening angle θ _{2 is} greater than the predetermined angle, the first body 10 needs to be positioned for a time interval, and the detecting unit 106 causes the optical touch module 104 to perform the positioning function again.

Otherwise, as shown in FIG. 3, when the opening angle θ _{2 is} greater than the predetermined angle and the first body 10 has an instantaneous swing speed, the detecting unit 106 still causes the optical touch module 104 to suspend its positioning function. . Therefore, it should be noted that the predetermined angle and the time interval in which the first body 10 needs to be positioned are determined according to different electronic device types and operation modes, and are not intended to limit the scope of the present invention.

Therefore, according to the electronic device 100 of the embodiment of the present invention, the detecting unit 106 can detect the opening angles θ ₁ and θ _{2 of the} housing 102 to effectively control the optical touch module 104. Start or stop, and thereby improve the problem of misunderstanding of the conventional optical touch screen positioning.
