Touch display

The present disclosure relates to a display, and more particularly to a touch display having a touch function.

Due to the advantages of thin size, light weight and low radiation, liquid crystal displays have gradually become the mainstream of the market. Most current displays have touch functions. However, as the size of the display is larger, the signal transmission line inside the display becomes longer. Since the transmission line has a large equivalent impedance, it affects the correctness of the signal on the transmission line.

The present disclosure provides a touch display including a first substrate, a second substrate, and a display medium layer. The display medium layer is disposed between the first and second substrates. The first substrate includes a plurality of pixel units, a first touch electrode, and a plurality of first connecting lines. The pixel units are arranged in an array. The first touch electrode corresponds to at least one pixel unit. Each of the first connecting lines extends in a first direction and is coupled between the first touch electrodes and a touch integrated circuit.

FIG. 1 is a cross-sectional view of a touch display of the present disclosure.

2, 3, 4A~4D, 5A, 5B, and 6-8 are schematic diagrams of the touch element layer of the present disclosure.

FIG. 1 is a possible cross-sectional view of the touch display of the present disclosure. As shown, the touch display 100 includes at least a first substrate 110, a display device layer 120, a touch device layer 130, a display dielectric layer 140, and a second substrate 150. The display element layer 120 is formed over the first substrate 110. In one possible embodiment, display element layer 120 has at least one metal layer (not shown) for forming complex pixel elements 121. The pixel units 121 may be arranged in an array, but are not intended to limit the disclosure. In other embodiments, the pixel units 121 may be arranged in a delta manner.

The touch element layer 130 is disposed on the display element layer 120, but is not intended to limit the disclosure. In other possible embodiments, the touch element layer 130 is disposed between the display element layer 120 and the first substrate 110. When the touch element layer 130 is disposed on the display element layer 120, the arrangement relationship between the display element layer 120 and the touch element layer 130 is referred to as an upper top com architecture. When the display device layer 120 is disposed on the touch device layer 130, the arrangement relationship between the display device layer 120 and the touch device layer 130 is referred to as a top pixel structure.

The touch element layer 130 may have at least one metal layer for forming a plurality of touch electrodes SC and a connection line ML connecting the touch electrodes SC. In a touch detection mode, the touch electrode SC receives the detection signal provided by a touch integrated circuit 131 through the connection line ML. The touch integrated circuit 131 detects the electrical change of the touch electrode SC through the connection line ML to determine whether the user touches the touch display 100. in In a display mode, the touch integrated circuit 131 does not control the voltage level of the touch electrode SC. At this time, the touch electrode SC receives a common voltage and acts as a common electrode.

The display medium layer 140 is disposed between the touch element layer 130 and the second substrate 150. The display medium on which the dielectric layer 140 is displayed may be a liquid crystal or an organic light emitting diode. In this embodiment, since the touch element layer 130 is disposed between the display medium layer 140 and the first substrate 110, the touch display 100 is an in-cell architecture.

The second substrate 150 has a color filter layer 151. The color filter layer 151 has a plurality of color filters for allowing light of a specific color to pass. In a possible embodiment, each color filter element corresponds to a pixel unit 121. In another possible embodiment, the second substrate 150 may also have no color filter layer 151. In another possible embodiment, the first substrate 110 has a color filter layer 151.

FIG. 2 is a possible schematic diagram of the touch element layer 130 of the present disclosure. The touch device layer 130 includes at least a plurality of touch electrodes and a touch integrated circuit.

Sexual change to determine where the touch is. In a display mode, the touch integrated circuit 210 does not control the voltage levels of the touch electrodes SC ₁ -SC ₉ . In this mode, the touch electrodes SC ₁ to SC ₉ function as a common electrode and receive a common voltage.

In this embodiment, since the connection lines ML ₁₁ to ML ₂₈ are independent, the touch integrated circuit 210 can provide different detection signals to the same touch electrode. For example, the touch integrated circuit 210 through a first connection line ML ₁₃ provides signal to detect the touch electrode SC _1, and provides a second detection signal through connection lines ML ₁₄ to touch electrode SC _1. The first detection signal may be the same or different from the second detection signal. In this example, since the touch integrated circuit 210 provides two detection signals to the touch electrodes SC ₁ through the independent connection lines ML ₁₃ and ML ₁₄ , the voltage levels of different regions of the touch electrodes SC ₁ can be controlled.

In this embodiment, each touch electrode is coupled to the control integrated circuit 210 through a plurality of connection lines. For example, the touch electrode SC _{1 is} coupled to the ML ₁₄ via the connection line ML ₁₃ and the contact control body circuit 210; the touch electrode SC _{4 is} coupled to the ML ₁₅ via the connection line ML ₁₂ and the contact control body circuit 210; the touch electrode SC _{7 is} coupled to the control integrated circuit 210 via the connection line ML ₁₁ and the ML ₁₆ .

In another possible embodiment, the left side distance LD _{21 is} smaller or larger than the right side distance RD ₂₁ . In other embodiments, at least one of the left side distances LD ₂₁ LD LD ₂₉ may be equal to or not equal to the other of the left side distances LD ₂₁ LD LD ₂₉ . Likewise, at least one of the right side distances RD ₂₁ ~ RD ₂₉ may or may not be equal to the other of the right side distances RD ₂₁ ~ RD ₂₉ .
