In the following, a plurality of embodiments of the present invention will be disclosed in the drawings, and for the sake of clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not applied to limit the creation. That is to say, in the implementation part of this creation, these practical details are not necessary. In addition, some of the conventional structures and elements are shown in the drawings in a simplified schematic manner in order to simplify the drawings.

1 is a schematic cross-sectional view of an organic light emitting diode touch display panel according to an embodiment of the present invention, and FIG. 2 is a top view of an embodiment of the touch sensing component 300 of FIG. 1 . The OLED touch display panel includes a first substrate 100 , a second substrate 200 , a touch sensing component 300 , and an organic light emitting diode display assembly 400 . The touch sensing component 300 is disposed between the first substrate 100 and the second substrate 200. The organic light emitting diode display assembly 400 is placed on the second substrate 200. The organic light emitting diode display assembly 400 includes an anode layer 410, a light emitting layer 420, and a common electrode layer 430. The anode layer 410 is interposed between the first substrate 100 and the second substrate 200.

Features. Compared with the conventional organic light-emitting diode touch display panel, the present embodiment can reduce at least one touch electrode layer, which is advantageous for thinning the organic light-emitting diode touch display panel. On the other hand, since the touch sensing component 300 is disposed between the first substrate 100 and the second substrate 200, the touch sensing component 300 is not placed on the first substrate 100 (for example, a glass substrate). on. In the embodiment, the first substrate 100 can protect the touch sensing component 300 without adding a protective substrate, that is, the entire device requires only two substrates (ie, the first substrate 100 and the second substrate 200). That is, it also contributes to the thinning of the organic light emitting diode touch display panel.

Next, please refer to FIG. 2 and FIG. 3A together, wherein FIG. 3A is a schematic cross-sectional view along the line segment 3A-3A of FIG. 2 . In this embodiment, the touch sensing component 300 includes a plurality of first electrode patterns 302, a plurality of second electrode patterns 304, a plurality of isolation electrode patterns 306, a plurality of lower connection elements 308, a plurality of isolation members 312, and a plurality of Upper connection elements 314. The second electrode pattern 304 and the first electrode pattern 302 are alternately arranged to form a matrix. The isolation electrode pattern 306 is interposed between the first electrode pattern 302 and the second electrode pattern 304. The materials of the isolation electrode pattern 306, the first electrode pattern 302 and the second electrode pattern 304 are both conductors and insulated from each other. Detailed The isolation electrode pattern 306, the first electrode pattern 302 and the second electrode pattern 304 are all of the same material, are in the same layer structure, and can be completed in the same process. For example, a patterned conductive layer may be deposited on the light emitting layer 420 (as shown in FIG. 1 ) to form the isolation electrode pattern 306 , the first electrode pattern 302 and the second electrode pattern 304 on the light emitting layer 420 . However, this creation is not limited to this. The lower connecting members 308 respectively connect the adjacent two second electrode patterns 304 arranged in the first direction D1. The first electrode pattern 302, the second electrode pattern 304, the isolation electrode pattern 306, and the lower connection member 308 constitute a common electrode layer 430. The insulating members 312 are respectively placed on the lower connecting member 308, for example, in FIG. 3A, the insulating member 312 is placed on the lower connecting member 308, the isolation electrode pattern 306, and the first electrode pattern 302. The upper connecting members 314 are respectively disposed on the insulating member 312 and span the adjacent two first electrode patterns 302 arranged in the second direction D2. The first direction D1 is substantially orthogonal to the second direction D2.

The touch sensing component 300 of the present embodiment may be a single-sided transparent conductive film (also referred to as a Single Indium Tin Oxide Structure, SITO) architecture. Specifically, the first electrode pattern 302 constitutes a plurality of electrodes extending along the second direction D2 via the connection of the upper connection member 314, and the second electrode pattern 304 constitutes a plurality of edges via the connection of the lower connection member 308. An electrode extending in the first direction D1. In this embodiment, the electrode extending along the second direction D2 can serve as the touch transmission electrodes T1, T2, and T3 (ie, composed of the first electrode pattern 302), and the electrode extending along the first direction D1 can serve as the electrode. The touch receiving electrodes R1, R2, R3 and R4 (that is, composed of the second electrode pattern 304). However, in other embodiments, the reverse is also possible. In Fig. 2, for the sake of clarity, only three transmission electrodes (ie, transmission power) are shown. The poles T1, T2, T3) and the four receiving electrodes (ie, the receiving electrodes R1, R2, R3, R4). However, the number is merely an illustration and is not intended to limit the creation. The person skilled in the art belongs to the general knowledge, and the number of the transfer electrodes T1, T2, T3 and the receiving electrodes R1, R2, R3, R4 should be flexibly selected according to actual needs.

In addition, as described above, the materials of the first electrode pattern 302, the second electrode pattern 304, the isolating electrode pattern 306, and the lower connecting member 308 are all conductive materials, such as metal oxides (such as Indium Tin Oxide (ITO). ). The material of the upper connecting member 314 is also a conductive material such as metal.

Each of the first electrode pattern 302 and the second electrode pattern 304 may be a diamond shape (or a hexagon), and the isolation electrode pattern 306 is disposed around the first electrode pattern 302 and the second electrode pattern 304. Each of the first electrode patterns 302, the second electrode patterns 304, and the isolation electrode patterns 306 overlaps with a plurality of pixel units (not shown) of the second substrate 200 (which may be a thin film transistor array substrate), that is, The sizes of the first electrode pattern 302, the second electrode pattern 304, and the isolation electrode pattern 306 are all larger than the size of the pixel unit.

An insulating layer 316 is present between the isolation electrode pattern 306 and the first electrode pattern 302, between the isolation electrode pattern 306 and the second electrode pattern 304, and between the isolation electrode pattern 306 and the lower connection element 308, such that the isolation electrode pattern 306 is The first electrode pattern 302, the second electrode pattern 304, and the lower connection member 308 can be insulated from each other. For the sake of clarity of the drawing, the insulating layer 316 is only shown in FIG. 3A and not shown in FIG. 2 . In addition, the orthographic projection of the insulating layer 316 on the second substrate 200 overlaps the black matrix (Black Matrix, BM, not shown) between the pixel units, so the presence of the insulating layer 316 does not affect the organic light emitting diode display. Opening of assembly 400 rate. On the other hand, if the pixel units are arranged in a matrix, the edges of the first electrode pattern 302 and the second electrode pattern 304 (that is, the position of the insulating layer 316) are enlarged, and the edges thereof are saw-toothed.

Additionally, for the sake of clarity, the dimensions of the connecting elements 314 on Figure 2 are drawn in a more exaggerated manner. In fact, the orthographic projection of the upper connecting component 314 on the second substrate 200 also overlaps the black matrix between the pixel units, so that even if the material of the upper connecting component 314 is metal, the organic light emitting diode display component 400 is not affected. The aperture ratio.

The structure of the insulating member 312 is not limited to the above. Please refer to FIG. 3B , which is a schematic cross-sectional view of the touch sensing component 300 according to another embodiment of the present invention. In the present embodiment, the insulating member 312 can be a one-layer structure covering the common electrode layer 430 (as shown in FIG. 1). The insulating member 312 has a plurality of through holes 313 therein to expose a portion of the first electrode pattern 302. The upper connecting member 314 is connected to the first electrode pattern 302 via the through hole 313 to electrically connect the adjacent two first electrode patterns 302. Other details of the present embodiment are the same as those of FIG. 3A, and therefore will not be described again.

Then return to Figure 2. In the embodiment, the touch sensing component 300 further includes a touch signal source 392, a signal detector 394, and a common voltage source 396. The touch signal source 392 is connected to the first electrode pattern 302, and the first electrode pattern 302 is connected, for example, by the upper connecting member 314. The signal detector 394 is connected to the second electrode pattern 304. The common voltage source 396 is connected to the isolation electrode pattern 306. The touch signal source 392 is configured to provide a common voltage or a touch transmission signal of the first electrode pattern 302. The signal detector 394 is configured to provide a common voltage of the second electrode pattern 304 or detect the second electrode pattern 304 and the first electrode pattern 302. The coupling capacitors are used, and the common voltage source 396 is used to provide the isolation electrode pattern 306 with a common voltage or to be at a floating potential. In one or more embodiments, the touch signal source 392, the signal detector 394, and the common voltage source 396 can be different circuit components, or can be combined into a single circuit component. The present invention is not limited thereto.

Please refer to FIG. 1 , FIG. 2 and FIG. 4 together. FIG. 4 is the transmission electrodes T1 T T3 , the receiving electrodes R1 R R4 , the isolation electrode pattern 306 and the anode layer 410 of FIG. 1 . A signal map between time t0 and tn+1. For the sake of clarity, only the display signal DS received by a portion of the anode layer 410 corresponding to a single pixel unit is shown. In operation, during the first timing (between times t0 and t1), the organic light emitting diode touch display panel is in a display state, so the touch signal source 392 provides the common voltage Vcom to the first electrode pattern 302 (ie, The transmission electrodes T1 T T3), the signal detector 394 provides the common voltage Vcom to the second electrode pattern 304 (ie, the receiving electrodes R1 R R4), and the common voltage source 396 provides the common voltage Vcom to the isolated electrode pattern 306. At the same time, the second substrate 200 (in the present embodiment, the thin film transistor array substrate) is provided with the display signal DS to the anode layer 410. More specifically, the anode layer 410 is divided into a plurality of pixel electrodes (not shown) corresponding to the pixel units of the second substrate 200, respectively. The different pixel units can provide different display signals DS to the pixel electrodes of the anode layer 410. The gray scale of each pixel unit is determined by the voltage of the display signal DS. The common voltage Vcom of the display signal DS of the anode layer 410 and the common electrode layer 430 forms a current in the light-emitting layer 420 to convert its electrical energy into visible light energy to emit light. Therefore, in the first timing, the organic light emitting diode touch display panel is generated. Display the screen.

Then, in the second timing (between times t1 and tn), the OLED touch display panel is in a touch state, so that the touch transmission signal TS is sequentially provided to the first electrode pattern 302, and the first detection is performed sequentially. The coupling capacitance of the two electrode patterns 304 is such that the isolation electrode pattern 306 is at a floating potential. In detail, during the first sub-timing (between times t1 and t2), the touch signal source 392 provides the touch transmission signal TS to the transmission electrode T1 (ie, the portion of the first electrode pattern 302), and the signal detector 394 sequentially detects the coupling capacitance between the receiving electrodes R1 R R4 (ie, the second electrode pattern 304) and the transmitting electrode T1, and at this time, the common voltage source 396 is not energized to the isolation electrode pattern 306, so that it is at a floating potential. . Therefore, the isolation electrode pattern 306 is separated, the coupling electrode is generated between the transmission electrode T1 and the receiving electrode R1 to R4, and the signal detector 394 can determine the position by sequentially detecting the coupling capacitance of the receiving electrodes R1 to R4. Whether it is touched.

Then, at the second sub-timing (between times t2 and t3), the touch signal source 392 provides the touch transmission signal TS to the transmission electrode T2 (ie, the other portion of the first electrode pattern 302), and the signal detector 394 The coupling capacitance between the receiving electrodes R1 R R4 and the transmitting electrode T2 is sequentially detected, and the isolated electrode pattern 306 is also at a floating potential. Therefore, the isolation electrode pattern 306 is separated, the coupling electrode is generated between the transmission electrode T2 and the receiving electrode R1 to R4, and the signal detector 394 can determine the position by sequentially detecting the coupling capacitance of the receiving electrodes R1 to R4. Whether it is touched. In this way, as long as the touch signal source 392 provides the touch transmission signal TS to the transmission electrodes T1~T3 according to the timing, the signal detector 394 detects the receiving electrodes R1~R4 according to the timing. By transmitting the coupling capacitance between the electrodes T1 and T3, the position of the touch excitation can be interpreted.

After completing one of the first timing and the second timing (ie, time t0 to tn), the organic light emitting diode touch display panel is again in the display state (between times tn and tn+1), The OLED touch display panel generates the next display screen. In this way, as long as the first timing and the second timing are repeated, the organic light emitting diode touch display panel can have both display and touch functions.

In the present embodiment, only the first timing (ie, time t0 to t1, time tn to tn+1, ...) is the display state, so the display signal DS is a pulse signal, compared to the conventional one. Continuous signal, the pulse signal of this embodiment has the advantage of eliminating image sticking. In addition, since the organic light-emitting diode system is energized by the anode layer 410 and the common electrode layer 430, a current flows through the light-emitting layer 420 to convert electric energy into visible light energy to emit light. Conversely, when the anode layer 410 is not energized, the light-emitting layer 420 does not emit light, and thus the organic light-emitting diode has a high reaction speed. Even if the display signal DS is a pulse signal, as long as there is sufficient current in the light-emitting layer 420 to emit light, there is almost no problem of delaying the reaction. In the touch state, even if the first electrode pattern 302 and the second electrode pattern 304 are intermittently energized, since the anode layer 410 is not energized, no current is generated in the light-emitting layer 420, and no light is emitted. In summary, the organic light emitting diode touch display panel of the present embodiment has a distinct display state and a touch state, and the two states do not interfere with each other.

Then please return to Figure 1. In the present embodiment, the organic light emitting two The polar touch display panel may further include a sealing material 500 disposed between the first substrate 100 and the second substrate 200 and disposed around the touch sensing component 300 and the organic light emitting diode display assembly 400. The sealing material 500 can block the outside air, and the luminescent layer 420 of the organic light emitting diode display assembly 400 is prevented from being exposed to air and oxidized.

In the embodiment, the touch sensing component 300 includes a plurality of first electrode patterns 322a-322n, a plurality of second electrode patterns 325a-325n, and a plurality of isolation electrode patterns 328. The first electrode patterns 322a to 322n and the second electrode patterns 325a to 325n are wedge-shaped and alternately arranged, respectively. The isolation electrode pattern 328 is interposed between the first electrode patterns 322a to 322n and the second electrode patterns 325a to 325n. The first electrode patterns 322a-322n, the second electrode patterns 325a-325n and the isolation electrode pattern 328 are insulated from each other, and the first electrode patterns 322a-322n, the second electrode patterns 325a-325n and the isolation electrode pattern 328 are composed as shown in FIG. The common electrode layer 430 is shown.

In detail, the first electrode patterns 322a-322n, the second electrode patterns 325a-325n and the isolation electrode patterns 328 are all of the same material, are in the same layer structure, and can be completed in the same process. For example, a patterned conductive layer may be deposited on the light-emitting layer 420 (as shown in FIG. 1) to form the first electrode patterns 322a-322n, the second electrode patterns 325a-325n, and the isolation electrode pattern 328. However, this creation is not limited to this. The material of the first electrode patterns 322a-322n, the second electrode patterns 325a-325n and the isolation electrode pattern 328 may be metal oxide.

In addition, the first electrode patterns 322a to 322n are disposed opposite to the second electrode patterns 325a to 325n. In other words, each of the first electrode patterns 322a-322n and the second electrode patterns 325a-325n has a bottom end 323 (326) and a top end 324 (327). The bottom end 323 of the first electrode patterns 322a-322n is adjacent to the top end 327 of the second electrode patterns 325a-325n, and the top end 324 of the first electrode patterns 322a-322n is adjacent to the bottom end 326 of the second electrode patterns 325a-325n. The isolation electrode pattern 328 is interposed between the first electrode patterns 322a-322n and the second electrode patterns 325a-325n, and between the isolation electrode patterns 328 and the first electrode patterns 322a-322n and the isolation electrode patterns 328 and the second electrode patterns 325a. There is an insulating layer (not shown) between ~325n. The description of the insulating layer is the same as that of Fig. 2, and therefore will not be described again.

In the embodiment, the touch sensing component 300 further includes a touch signal circuit 398 and a common voltage source 396. The touch signal circuit 398 connects the first electrode patterns 322a-322n and the second electrode patterns 325a-325n. The common voltage source 396 is connected to the isolation electrode pattern 328. The touch signal circuit 398 is configured to provide a common voltage or touch transmission signal for the first electrode patterns 322a-322n and the second electrode patterns 325a-325n, or to detect a coupling capacitor, and the common voltage source 396 is used to provide the isolation electrode pattern 328.

For the sake of clarity, only the display signals received by a portion of the anode layer 410 corresponding to a single pixel unit are shown. DS. In operation, during the first timing (between times t0 and t1), the OLED touch display panel is in a display state, so the touch signal circuit 398 provides the common voltage Vcom to the first electrode patterns 322a-322n. And the second electrode patterns 325a to 325n, and the common voltage source 396 supplies the common voltage Vcom to the isolation electrode pattern 328. At the same time, the second substrate 200 provides the display signal DS to the anode layer 410. Therefore, in the first timing, the organic light emitting diode touch display panel is capable of generating a display image.

Then, in the second timing (between times t1 and tn), the OLED touch display panel is in a touch state, so when the first sub-timing (between times t1 and t2), the touch signal circuit 398 The touch transmission signal TS is detected to the second electrode pattern 325a and the discharge speed is detected. At this time, the common voltage source 396 is not energized to the isolation electrode pattern 328 to be at a floating potential. Therefore, according to the difference in discharge speed, the touch signal circuit 398 can determine whether the second electrode pattern 325a is contacted and its contact position.

Then, in the second sub-timing (between times t2 and t3), the touch signal circuit 398 provides the touch transmission signal TS to the first electrode pattern 322a to detect the discharge speed thereof, and the common voltage source 396 at this time is The isolation electrode pattern 328 is not energized to a floating potential. The touch signal circuit 398 can determine whether the first electrode pattern 322a is contacted and its contact position according to the difference in discharge speed.

When one cycle of the first timing and the second timing is completed (ie, time t0 to After tn), the organic light emitting diode touch display panel is again in the display state (between time tn and tn+1), so the organic light emitting diode touch display panel generates the next display image. In this way, as long as the first timing and the second timing are repeated, the organic light emitting diode touch display panel can have both display and touch functions.

In some embodiments, the first electrode patterns 322a-322n and the second electrode patterns 325a-325n are simultaneously charged during the charging cycle, and the first electrode patterns 322a-322n are simultaneously applied during the discharge period after the charging cycle. The second electrode patterns 325a to 325n are discharged, and the residual voltages of all the first electrode patterns 322a to 322n and the second electrode patterns 325a to 325n are compared to determine the touch position. Alternatively, during the discharge period, the time at which the first electrode patterns 322a to 322n and the second electrode patterns 325a to 325n are discharged to a predetermined voltage is compared to determine the touch position.

The touch mode described above is a self-capacitance touch technology. However, in other embodiments, a mutual capacitance touch technology can also be used. In detail, in the second timing (between times t1 and tn), the organic light emitting diode touch display panel is in a touch state, so when the first sub timing (between times t1 and t2), the touch The signal circuit 398 provides the touch transmission signal TS to the first electrode pattern 322a, and the touch signal circuit 398 sequentially detects the coupling capacitance between the second electrode patterns 325a, 325b and the first electrode pattern 322a, and the sharing is performed at this time. Voltage source 396 is then not energized to isolation electrode pattern 328, causing it to be at a floating potential. Therefore, the isolation electrode pattern 328 is separated, the coupling capacitance is generated between the first electrode patterns 322a and the second electrode patterns 325a and 325b, and the touch signal circuit 398 sequentially detects the second electrode patterns 325a. The coupling capacitance of 325b can determine whether each position is touched.

Then, in the second sub-sequence (between times t2 and t3), the touch signal circuit 398 provides the touch transmission signal TS to the second electrode pattern 325b, and then the touch signal circuit 398 sequentially detects the first electrode pattern 322a. The coupling capacitance between 322b and the second electrode pattern 325b, at which time the isolation electrode pattern 328 is also at a floating potential. Therefore, the isolation capacitor pattern 328 is separated, the coupling capacitance is generated between the second electrode pattern 325b and the first electrode patterns 322a and 322b, and the touch signal circuit 398 sequentially detects the coupling capacitance of the first electrode patterns 322a and 322b. , you can determine whether each location is touched. In this way, as long as the touch signal circuit 398 provides the touch transmission signal TS to the first electrode patterns 322a-322n and the second electrode patterns 325a-325n according to the timing, and the coupling capacitance is detected according to the timing, the touch excitation can be interpreted. position.

After completing one of the first timing and the second timing (ie, time t0 to tn), the organic light emitting diode touch display panel is again in the display state (between times tn and tn+1), The OLED touch display panel generates the next display screen. In this way, as long as the first timing and the second timing are repeated, the organic light emitting diode touch display panel can have both display and touch functions.

In this embodiment, the touch sensing component 300 includes a plurality of first electrode patterns 332a-332n, a plurality of first isolation electrode patterns 336, a plurality of second electrode patterns 334a-334n, and a plurality of second isolation electrode patterns 338. . The first isolation electrode pattern 336 and the first electrode patterns 332a-332n are alternately arranged in the first direction D3 (that is, the direction in which the first isolation electrode pattern 336 and the first electrode patterns 332a to 332n are alternately arranged is the first direction D3), and The common electrode layer 430 is composed. The second isolation electrode pattern 338 and the second electrode patterns 334a-334n are alternately arranged in the second direction D4 (that is, the direction in which the second isolation electrode pattern 338 and the second electrode patterns 334a-334n are alternately arranged is the second direction D4), One direction D3 is substantially orthogonal to the second direction D4.

The second electrode patterns 334a-334n can serve as the transmission electrodes of the touch, and the first electrode patterns 332a-332n can serve as the receiving electrodes of the touch.

From the perspective of the control device, since the thickness of the laminated structure between the common electrode layer 430 and the anode layer 410 (ie, the distance D) is not large, the voltage value of the touch transmission signal corresponding to the distance D is much lower than that of the excitation light. The initial voltage of the layer 420, that is, the voltage value of the display signal is greater than the voltage value of the touch transmission signal, so that the organic light emitting diode does not conduct light in the touch state.
