4 illustrates a structure of a touch screen related to the present invention.

As shown in FIG. 4, the display module 151 according to the present invention forms a mutual layer structure with the touch pad 400 and is configured as a touch screen 500.

As illustrated in FIG. 4, the touch pad 400 includes a quadrangular conductive film 411 made of a transparent conductive material such as indium tin oxide (ITO) and metal electrodes formed at each corner of the conductive film 411. 412-1 to 412-4). The passivation layer 420 may be formed on the conductive layer 411.

The touch pad 400 is a capacitive sensing type position detecting apparatus, and the transmitting side metal electrode is applied by an alternating voltage applied to the transmitting side metal electrodes T: 412-1 and 412-4. Electrical field lines are formed between the electrodes T: 412-1 and 412-4 and the receiving metal electrodes R: 412-2 and 412-3. The formed electric line of force extends to the outside of the touch panel 400 through the passivation layer 420. Accordingly, when the object (for example, a user's finger) approaches the touch pad 400 or directly touches the touch pad 400, the reception side metal electrodes R 412 by partially blocking the electric line of force. -2, 412-3) changes in the phase and magnitude of the current flowing. This is because the human body has a capacitance of several pF with respect to the ground, and thus distorts electric force lines formed on the touch panel 400 when the user approaches or touches the finger with the touch panel 400.

In addition, the processors (not shown) configured in the portable terminal 100 use the current change of the receiving metal electrodes R 412-2 and 412-3 in response to a touch operation of the object. The distance and the location where the touch is generated can be detected.

In addition, the object includes not only a user's finger, but also any object that the portable terminal 100 can recognize a touch input by distorting an electric force line formed on the touch pad 400.

FIG. 5 is a diagram illustrating a principle of detecting a proximity distance of an object using the touch screen of FIG. 4.

As illustrated in FIG. 5, the AC voltage 430 is applied to the transmitting side metal electrode 412-1 among the metal electrodes 412-1 to 412-4 formed on the transparent conductive film 411, thereby transmitting the above-described voltage. Electrical force lines 501 to 503 are formed between the side metal electrode 412-1 and the receiving side metal electrode 412-2. The electric field lines 501 to 503 extend in a vertically upward direction (ie, z direction) of the touch screen 500.

In addition, according to the distance between the user's finger 510 and the touch screen 500, the amount of electric field lines 501 to 503 blocked by the finger 510 is changed. That is, as the finger 510 gets closer to the touch screen 500, the influence of the finger 510 on the electric field lines 501 to 503 increases.

As described above, the influence applied to the electric field lines 501 to 503 by the finger 510 may affect the current applied to the current detectors 440-1 and 440-2 connected to the metal electrodes 412-1 and 412-2. The current detectors 440-1 and 440-2 detect the change in the current and provide it to an analog-digital converter (ADC) 450. Then, the analog-to-digital converter (ADC) 450 converts the amount of change of the current input in the form of an analog signal into a digital value, and provides it to the touch time measuring unit 460.

Then, the touch time measuring unit 460 may recognize that the touch screen 500 is close to the finger 510 from the information on the amount of current change provided from the analog-to-digital converter (ADC) 450. The length of time the finger 510 stays within a touch recognition effective distance (ie, 'd1' in FIG. 5) is measured. Accordingly, when the finger 510 stays within the proximity touch recognition effective distance (ie, 'd1' in FIG. 5) for more than a predetermined time (for example, 1 second), the touch time measuring unit 460 according to the present invention. It may be recognized that the proximity touch or direct touch operation according to the present invention is performed. On the other hand, the touch time measuring unit 460 may keep the finger 510 within a proximity touch recognition effective distance (ie, 'd1' in FIG. 5) for a time shorter than a predetermined time (for example, 1 second). In this case, it may be determined that the proximity touch or the direct touch operation according to the present invention is not performed.

As such, when it is determined by the touch time measuring unit 460 that the finger 510 has a touch input based on a proximity touch or a direct touch operation on the touch screen 500, the touch time measuring unit 460 ) Provides the distance detection unit 470 with information about the touch input generation information and the current change amount.

Then, the distance detection unit 460 is a distance between the finger 510 and the touch screen 500 from the information on the amount of current change, that is, the finger 510 is vertically upward from the touch screen 500 ( That is, the distance spaced in the z direction) is calculated.

Specifically, when the finger 510 is located closer than d1 (eg, 30 mm) and farther than d2 (eg, 20 mm) from the vertical upward direction (ie, z direction) of the touch panel 400. The distance detection unit 460 determines that the finger 510 is within a touch recognition effective distance at which the touch screen 500 starts to detect whether an external object is touched. Thus, a function corresponding to the proximity touch operation according to the present invention can be provided. Here, the proximity touch refers to a state in which an object (for example, a user's finger) is located within the touch recognition effective distance of the touch screen 500 to input a user command, and the proximity touch means that the object is located on the touch screen. The object is distinguished from a direct touch operation in which the object directly touches the touch screen 500 in that it does not directly touch 500.

Further, when the finger 510 is located closer than d2 (for example, 20 mm) and farther than d3 (for example, 10 mm) from the vertical upward direction (ie, z direction) of the touch screen 500 ( That is, when the distance is between d2 and d3), the distance detector 460 may determine that the finger 510 is very close to the touch screen 500.

Further, when the finger 510 is positioned at a distance closer to d3 (eg, 10 mm) from the vertically upward direction (ie, z direction) of the touch screen 500 (ie, located within d3) or the finger ( When the 510 directly touches the surface of the touch screen 500, the distance detector 460 determines that the finger 510 directly touches the touch screen 500 within an error range.

In FIG. 5, the touch operation of the finger 510 is divided into three steps according to the distance between the finger 510 and the touch screen 500, but the touch operation is more precisely performed in four or more steps. Can be distinguished.

Next, the position detector 480 determines the position on the touch screen 500 indicated by the finger 510, that is, the horizontal coordinates in the x and y directions on the touch screen 500, from the information on the amount of change of the current. Calculate The y direction is a direction perpendicular to the x and z directions shown in FIG. 5.

The measured vertical distance between the finger 510 and the touch screen 500 and the horizontal coordinates of the finger 510 on the touch panel 400 are provided to the controller 180. Accordingly, the controller 180 determines a user's command according to the vertical distance and the horizontal coordinate, performs a control operation according to the user command, and also has a predetermined graphical user interface (GUI) on the display module 151. ).

FIG. 6 is a view for explaining a position detection principle of an object using the touch screen of FIG. 4.

Electric field lines (not shown) are formed between the -1 and 412-4 and the receiving metal electrodes R 412-2 and 412-3.

When the user's finger 510 is close to the touch panel 400 or directly touches the touch panel 400, a current change occurs in the metal electrodes 412-1 to 412-4. Then, the current detectors 440-1 to 440-4 measure the change in the amount of current, and as described above, the position detector 470 uses the finger 510 to change the amount of current. The horizontal coordinate (ie, xy coordinate) located on the 400 is detected and provided to the controller 180. Accordingly, the controller 180 recognizes a horizontal coordinate on the touch screen 500 that the finger 510 is touching, performs a user command corresponding to the touch operation, and performs an operation on the display module 151. It is possible to provide a predetermined graphical user interface (GUI).

In addition, in FIGS. 5 and 6, the touch time measuring unit 460, the distance detector 470, and the position detecting unit 480 are illustrated separately from each other according to respective functions, but the touch time measuring unit 460 is illustrated. The distance detector 470 and the position detector 480 may be formed in the controller 180.

In addition, in FIGS. 4 to 6, the touch screen 500 including the touch panel 400 according to the capacitive sensing method is taken as an example, and the object determines the proximity distance and the direct touch with the touch screen 500. Although the principle has been described, the type of the touch panel 400 or the metal configured in the touch panel 400 can be provided as long as it can provide a function of detecting the distance between the object and the touch screen 500 and the position indicated by the object. The arrangement of the electrodes 412-1 to 412-4 is not limited.

For example, the touch panel 400 may be a photoelectric sensor using a laser diode and a light emitting diode, a high frequency oscillating proximity sensor, and a magnetic proximity sensor using the object and the touch panel. In addition to being able to detect a proximity position between the 400, a resistive sensing type for forming a metal electrode on the upper or lower plate and detecting a change in voltage according to the position pressed by the object (Resistive Sensing Type ) And the capacitive sensing scheme may be implemented in combination with each other.
