In the description and drawings, particular embodiments of the invention have been disclosed in detail as being indicative of some of the ways in which the principles of the invention may be employed, but it is understood that the invention is not limited correspondingly in scope. Rather, the invention includes all changes, modifications and equivalents coming within the spirit and terms of the appended claims.
Features that are described and/or illustrated with respect to one embodiment may be used in the same way or in a similar way in one or more other embodiments and/or in combination with or instead of the features of the other embodiments. It should be emphasized that the term “includes/including” when used in this specification is taken to specify the presence of stated features, integers, steps or components but does not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.
Many aspects of the invention can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present invention. To facilitate illustrating and describing some parts of the invention, corresponding portions of the drawings may be exaggerated in size, e.g., made larger in relation to other parts than in an exemplary device actually made according to the invention. Elements and features depicted in one drawing or embodiment of the invention may be combined with elements and features depicted in one or more additional drawings or embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views and may be used to designate like or similar parts in more than one embodiment.
The drawings are included to provide further understanding of the present invention, which constitute a part of the specification and illustrate the preferred embodiments of the present invention, and are used for setting forth the principles of the present invention together with the description. The same element is represented with the same reference number throughout the drawings.
In the drawings:
The interchangeable terms “electronic apparatus” and “electronic device” include portable radio communication apparatus. The term “portable radio communication apparatus”, which hereinafter is referred to as a “mobile terminal”, “portable electronic device”, or “portable communication device”, includes all apparatuses such as mobile telephones, pagers, communicators, electronic organizers, personal digital assistants (PDAs), smartphones, portable communication devices or the like.
In the present application, embodiments of the invention are described primarily in the context of a portable electronic device in the form of a mobile telephone (also referred to as “mobile phone”). However, it shall be appreciated that the invention is not limited to the context of a mobile telephone and may relate to any type of appropriate electronic apparatus having the function of photographing and sound recording.
The embodiments of the present invention provide electronic equipment, including a touch screen (shown at 301 in several drawing figures).
In this embodiment, according to the principles of force decomposition and composition, when an inclined pressure is applied to the touch screen 301, pressures may be generated both in the horizontal direction and the vertical direction.
In this embodiment, the touch screen 301 may be a capacitive touch screen, and the horizontal pressure detecting device 101 may be a part of a resistive screen, and may be a resistive pressure detecting device. In particular implementation, the horizontal pressure detecting device 101 may be arranged at the peripheral of the touch screen 301, including the upper, the lower, the left, and the right.
In this embodiment, the horizontal pressure detecting device 101 may detect the pressure through the touch of touch points with a conductive layer, thereby further improving the precision of detection.
an isolation layer 401 arranged at the edge of the touch screen 301;
touch points 402 arranged on the isolation layer 401; and
a conductive layer 403 arranged opposite to the isolation layer 401; the conductive layer 403 is not in touch with (not touching) the touch points 402 when no pressure is applied.
Furthermore, the touch points 402 may be multiple, and the distances from at least two touch points to the conductive layer are different, i.e. the distances from each of the touch points to the conductive layer are not completely identical. For example, as shown in
When no pressure is applied to the isolation layer 401, the distance from the touch points 402 to the conductive layer 403 may be between 0.01 millimeter and 0.1 millimeter. What is described above is only exemplary description of the touch points, however, it is not limited thereto, and particular implementation may be determined as actually required.
In this embodiment, the isolation layer 401 may be of an elastic material, which is deformable when it is applied a slight pressure from the touch screen 301. The touch points 402 may be provided with ITO (indium tin oxide), forming a circuit when it is in touch with the conductive layer 403, thereby generating an electrical signal. The electrical signal may be generated in a manner of the prior art, which shall not be described any further.
Furthermore, the point gaskets 601 may be arranged spaced apart from the touch points 402, so as to improve the detection precision of the resistive screen. For example, five touch points 4021-4025 may be arranged between each two point gaskets 601. What is described above is exemplary only, and particular implementation may be determined as actually required.
Thus, the direction of the pressure applied to the touch screen in the horizontal direction may be determined by detecting the pressure applied to the touch screen in the horizontal direction by a resistive pressure detecting device 101, and the precision of detection is high, the manufacture is simple, and the cost is low.
In an embodiment, the processing unit 102 may include a position determining unit and a direction determining unit (not shown). The position determining unit determines the positions of the touch points 402 in touch with the conductive layer 403 according to the horizontal pressure signal output by the horizontal pressure detecting device 101; and the direction determining unit determines the direction of the pressure applied to the touch screen 301 in the horizontal direction according to the positions of the touch points 402 in touch with the conductive layer 401.
For example, as shown in
In an embodiment, the processing unit 102 may further include a number determining unit and a level determining unit (not shown in this figure). The number determining unit determines the number of the touch points in touch with the conductive layer according to the electrical signal output by the horizontal pressure detecting device 101; and the level determining unit determines the level of the pressure applied to the touch screen according to the number of the touch points in touch with the conductive layer.
For example, as shown in
If it is determined that the touch points in touch with the conductive layer are 4021 and 4024, the number determining unit may determine that the number of the touch points in touch with the conductive layer is “2”. Thus, the level determining unit may determine that the level of the pressure applied to the touch screen in the horizontal direction is “4”.
In another embodiment, the electronic equipment further includes a vertical pressure detecting device (not shown) arranged below the touch screen to detect the pressure applied to the touch screen in the vertical direction and generate a vertical pressure signal.
In particular, an existing pressure sensor may be used as the vertical pressure detecting device, or the structure shown in
The pressure processing unit 102 is further used to determine the level and direction of the pressure applied to the touch screen according to the horizontal pressure signal generated by the horizontal pressure detecting device 101 and the vertical pressure signal generated by the vertical pressure detecting device.
In particular, the level of the pressure applied in the horizontal direction (104, for example, as shown in
For example,
In specific implementation, an application programming interface may be provided to realize above function. For example, the following interface function may be provided:
Pressure.getRoughDirection( ).
The information on the direction of the pressure applied to the touch screen in the horizontal direction (such as “left”) may be returned via the interface function, indicative of that the direction of the pressure applied in the horizontal direction is “left”.
Or, the following interface function may also be provided:
Pressure.getPreciseDirection( ).
The information on the direction and level of the pressure applied to the touch screen may be returned via the interface function. For example, returning (left, 8) indicates that the direction of the pressure applied in the horizontal direction is “left”, and the level of the pressure applied in the horizontal direction is “8”; and returning (left, 53°, 8) indicates that the direction of the pressure applied is “left lower 53°”, and the level of the pressure applied is “8”. In this way, the result of detection will be more precise, and the application of the electronic equipment may perform application process according to such information.
What is described above is only exemplary description of the detection of pressure, however, it is not limited thereto, and particular implementation may be determined as actually required.
It can be seen from the above embodiments that the direction of the pressure applied to the touch screen may be determined by detecting the pressure applied to the touch screen in the horizontal direction by a resistive pressure detecting device, and the precision of detection is high, the manufacture is simple, and the cost is low.
The embodiments of the present invention further provide a pressure detecting method, applicable to a touch screen.
Step 801: generating a horizontal pressure signal by touch points moving in the horizontal direction and in touch with a conductive layer, the touch points being arranged on an isolation layer at the periphery of the touch screen; and
Step 802: determining the direction of the pressure applied to the touch screen in the horizontal direction according to the horizontal pressure signal.
In particular, a user may click or press the touch screen. In a case where the angle of a press is not vertical, a pressure is applied to the touch screen in the horizontal direction, and the isolation layer is pushed to slightly shift, causing the touch points to move slightly in the horizontal direction, thus making the touch points to be in touch with the conductive layer to generate a horizontal pressure signal.
Furthermore, in one embodiment, the touch points may be multiple, and the distances from at least two touch points to the conductive layer are different.
Step 901: making touch points arranged on an isolation layer to move in the horizontal direction when a pressure is applied in the horizontal direction to the isolation layer arranged at the periphery of the touch screen;
Step 902: generating a horizontal pressure signal by the touch points in touch with the conductive layer due to the movement of the touch points in the horizontal direction;
Step 903: determining the positions of the touch points in touch with the conductive layer according to the horizontal pressure signal; and
Step 904: determining the direction of the pressure applied to the touch screen in the horizontal direction according to the positions of the touch points in touch with the conductive layer.
As shown in
Step 905: determining the number of the touch points in touch with the conductive layer according to the horizontal pressure signal; and
Step 906: determining the level of the pressure applied to the touch screen in the horizontal direction according to the number of the touch points in touch with the conductive layer.
In one embodiment, the pressure detecting method may further include:
detecting the pressure applied to the touch screen in the vertical direction and generating a vertical pressure signal; and
determining the level and direction of the pressure applied to the touch screen according to the horizontal pressure signal and the vertical pressure signal.
It can be seen from the above embodiments that the direction of the pressure applied to the touch screen may be determined by detecting the pressure applied to the touch screen in the horizontal direction by a resistive pressure detecting device, and the precision of detection is high, the manufacture is simple, and the cost is low.
The embodiments of the present invention further provide a pressure detecting device arranged at the periphery of a touch screen. The pressure detecting device includes:

Furthermore, the touch points 402 may be multiple, and the distances from at least two touch points to the conductive layer 403 may be different. Preferably, the distances from the touch points to the conductive layer are between 0.01 millimeter and 0.1 millimeter when no pressure is applied to the isolation layer.
Furthermore, the pressure detecting device further includes: Point gaskets 601 arranged on the isolation layer 401 and in touch with the conductive layer 403 to space apart and support the isolation layer and the conductive layer. The point gaskets may be arranged spaced apart from the touch points.
