The operation of the conductive pattern 156 forming on the first area 151 at touch pad 150 is given to more detailed explanation below.As shown in Figure 4, when user contacts forms 136, user's finger (F) forms and contacts with 157e with at least two line 157d of conductive pattern 156.Therefore, the electric current providing in terminal flows along the trace of conductive pattern 156, and when user's finger (F) contacts with conductive pattern 156 formation, the resistance value of conductive pattern 156 changes.

In addition, when two line 157d of user's finger (F) contact

conductive pattern

156 and 157e, produce two contact point A and B, and when the position of contact point A and B changes, the distance between the distance between one end of conductive pattern 156 and a contact point (A) and the other end of conductive pattern 156 and another contact point (B) also changes.Therefore, increased resistance value depends on the position of contact point A and B and changes.

In addition, the quantity of electric charge that the two ends of conductive pattern 156 (X, Y) are located to record changes at each contact point according to the change of resistance value, and the set point that the value that the two ends at conductive pattern 156 (X, Y) located to record records previously in each contact area makes comparisons, to detect contact position.As mentioned above, Fig. 5 is the sectional view of the mobile terminal 100 obtained along the line V-V in Fig. 3.

Then, Fig. 6 is the sectional view of the mobile terminal 100 obtained along the line VI-VI in Fig. 3.With reference to Fig. 3 and Fig. 6, luminous plaque 160 is placed in the inner side of second area 152, and is configured to touching keypad-part 114 demonstration luminous patterns.In addition, shielding pattern 155 forms at the edge of touch pad 150, and external action is reduced to minimum, that is, the electromagnetic wave being produced by electronic device for example, on the impact of the signal of conductive pattern (signal transmitting via data wire 153).

In addition, can be by deposits conductive material on touch pad 150---for example metal material---form shielding pattern 155.Shielding pattern 155 also forms on the position corresponding with data wire 153, and forms at the surperficial opposite side of placing data wire 153.In this exemplary embodiment, data wire 153 forms in the inner side of touch pad 150, and shielding pattern 155 forms in the outside of touch pad 150.

Yet conversely, data wire 153 can shield pattern 155 in the formation of the outside of touch pad 150 and can form in the inner side of touch pad 150.In addition,

conductive pattern

156 and 158 can form on the same surface of placing data wire 153.In addition, on luminous plaque 160, form earth point 161, and shielding pattern 155 and earth point 161 electrical shorts.

In addition, the earth point 161 of luminous plaque 160 can be connected in various manners with shielding pattern 155, for example, by cable or contact, connect.Therefore,, by shielding earth point 161 electrical shorts of pattern 155 and luminous plaque 160, the voltage that produces spontaneous tabula rasa 160 is reduced to minimum to the impact of touch pad 150 operations.

Fig. 7 A-7D is the front view of the luminous plaque of Fig. 3, and wherein when touch keypad-part 114 is touched, the operation of luminous plaque 160 illustrates chronologically.As shown in the figure, luminous plaque 160 comprises and being treated separately with when touching keypad-part 118 and be touched, and lights separately the luminous pattern 162 of membrane keyboard part 154.In addition,, when applying touch to one in membrane keyboard part 154, luminous pattern 162 is lit, and makes thus user recognize that this touch has been input to membrane keyboard part 154.

In addition, luminous pattern 162 is placed on the region corresponding with membrane keyboard part 154, and in the embodiment shown in Fig. 7 A-7D, each luminous pattern 162 has a plurality of concentric circless, and they have different radiuses separately.In the following description, take the luminous pattern 162 that is arranged on luminous plaque 160 right parts is example.In addition, the round indication light state representing with solid line, and the circle being represented by dotted lines is indicated not luminance.

In addition, as shown in Fig. 7 A-7D, luminous pattern 162 comprises the first to fourth luminous pattern 162a-162d with different radii, and wherein luminous pattern 162a-162d according to its radius by arranged in sequence.In addition, the material that each luminous pattern 162a-162d can be controlled according to current strength by brightness is made, and can control separately to have the brightness changing along peripheral direction successively chronologically.In Fig. 7 A to 7D, compare the luminous pattern that darker solid line that other luminous pattern 162 thickness are larger represents brightness maximum.

In addition, luminous pattern 162 can be configured to make first to fourth luminous pattern 162a-162d with the passing of time successively in brightness maximum rating.For example, as shown in Figure 7 A, when touch is inputted to the membrane keyboard part 154 of touch pad 150, the first luminous pattern 162a is controlled as the brightest, and along with time lapse, as shown in Figure 7 B, the first luminous pattern 162a is dimmed, and the second luminous pattern 162 is controlled as the brightest simultaneously.

Similarly, as shown in Fig. 7 C, as time goes by, the 3rd luminous pattern 162c becomes the brightest, subsequently, as shown in Fig. 7 D, the 4th luminous pattern 162d become the brightest after, first to fourth the luminous of luminous pattern 162a-162d stops.Therefore, when user input is when touching the touch of keypad-part 114, the luminous pattern 162 of corresponding touch keypad-part 114 is lit, and now visual effect is realized as light is spread with annular along peripheral direction.

In addition, luminous pattern 162 can be controlled so as to separately and since the 4th luminous pattern 162d to the first luminous pattern 162d, be followed successively by the brightlyest, and ring light spreads along inward direction with the passing of time by this.In addition, in the above-described embodiments, four luminous pattern 162a-162d of arranged in sequence, but the number of luminous pattern can change as required.

Then, Fig. 8 A-8C is for explaining according to the plane graph of the mobile terminal of the operation of the mobile terminal of the embodiment of the present invention.As shown in Figure 8 A, touch screen portion 130 comprises menu or the icon 113c for the various functions of operating mobile terminal 100.Here, when user touches for example text message of a part of menu or icon 113c() time, carry out corresponding function.

As shown in Figure 8 B, touch screen portion 113 also comprises selectable list 113d and is placed in cursor or the pointer 113e on list 113d.Touch the form realization that keypad-part 114 can move the directionkeys of the cursor that is placed on list 113d or pointer here.In this example, when touch keypad-part 114 is touched, the luminous pattern of luminous plaque is touching demonstration in keypad-part 114, so that user identifies the touch keypad-part 114 being touched.

In addition, in Fig. 8 B, list 113d is telephone directory list, and in this example, by touching, with the membrane keyboard part 154(Fig. 4 that is placed in bottom, this membrane keyboard part 154 is shown) corresponding region, cursor or pointer 113c can move down, and by pressing the center key 118 that is placed in middle section, the information that user can be gone for (for example telephone number) is presented in touch screen portion 113 subsequently.In addition, as shown in Figure 8 B, when bottom that user has touched membrane keyboard part 154 is when rolling telephone directory list downwards, the time quantum that can touch membrane keyboard part 154 based on user is lighted luminous pattern 162.

As shown in Figure 8 C, user can be by handling the second and the

3rd actuation unit

123 and 124 and handle membrane keyboard part 154 to terminal input character, numeral, symbol etc.User also can for example select telephone number by the phone icon contacting on the first actuation unit 117.Therefore,, as shown in the embodiment in Fig. 8 A-8C, user can input easily and select different options and see the correct region having touched in terminal.

In addition,, for ease of user's touch input, be shown in the menu of touch screen portion 113 or size that icon can be corresponding with user's finger or larger size and show.In addition, according to the present invention, the conductive pattern 156(of the touch pad 150 of all embodiment is shown in Fig. 4) be suitable for the touch that sensing inputs to the identified region forming with above-mentioned size.

Then, Fig. 9 is according to the plane graph of the touch pad 250 of second embodiment of the invention, and Figure 10 is touch pad in Fig. 9, is arranged on the sectional view of the mobile terminal on the first fuselage.In addition, in Figure 10, touch pad 250 and related elements thereof are exaggerated for illustration purpose.
