Description
Technical Field
The present invention relates to the field of touch technologies, and in particular, to a touch display device and an electronic apparatus.
Background
With the rapid development of display technologies in recent years, a touch display device that enables input of information has attracted attention by mounting a touch device on a display device such as a liquid crystal display device or integrating the touch device with the display device and displaying various button images and the like on the display device instead of usual mechanical buttons. Since the touch display device does not require an input device such as a keyboard, a mouse, and a keypad, the use of such a touch display device also tends to be expanded to be applied to a portable information terminal such as a mobile phone.
In the related art, a touch display device detects a touch event by responding to a change of an external proximity or contact object using an electrostatic capacitance formed at an intersection of a sensing electrode and a driving electrode. Here, the electrodes are formed of a semi-permeable material, but light transmittances of a portion having the electrodes and a portion having no electrodes are different, and thus, the touch display device has optical visibility.
Disclosure of Invention
The embodiment of the invention provides a touch display device and electronic equipment, which are used for solving the problem of optical visibility of the touch display device in the prior art.
An embodiment of the present invention provides a touch display device, including:
the display unit and the touch unit;
the display unit includes a pixel array having a plurality of sub-pixels including sub-pixels of at least two different colors;
the touch unit comprises touch electrodes arranged opposite to the display unit, the touch electrodes comprise a plurality of first touch electrodes extending along a first direction and arranged along a second direction, and the first direction is crossed with the second direction;
the projection of the first touch electrode on the plane of the pixel array at least penetrates through the sub-pixels with two different colors.
Because the projection of the first touch electrode on the plane of the pixel array at least penetrates through the sub-pixels with two different colors, the difference of the light transmittance of the touch unit and the light transmittance of the display unit are reduced, and the visibility of the touch display device is reduced;
a first slit is formed between the adjacent first touch electrodes, the first slit extends along the first direction, and the projection of the first slit on the plane where the pixel array is located at least penetrates through the sub-pixels with two different colors;
each first slit comprises a plurality of sub first slits extending and arranged along a first direction, and the projection of the sub first slits on the plane of the pixel array at least penetrates through 1 sub pixel or at least two sub pixels with different colors.
Because the orthographic projection of the first slit between the adjacent first touch electrodes on the plane where the pixel array is located at least penetrates through the two sub-pixels with different colors, the orthographic projection of the first slit on the plane where the pixel array is located cannot always penetrate through the sub-pixels with the same color, and therefore the visibility of the touch display device is reduced.
Preferably, the pixel array comprises a plurality of rows of sub-pixels arranged along the first direction and a plurality of columns of sub-pixels arranged along the second direction, the sub-pixels in a column have the same color, and the sub-pixels in a row have at least two different colors.
Preferably, the sub-pixels in a row have three different colors, red, green and blue, respectively, and are arranged in a cycle in the first direction; alternatively, the sub-pixels in a row have four different colors, red, green, blue, white, respectively, and are arranged cyclically in the first direction.
Preferably, the pixel array further includes a plurality of scan lines extending along the first direction and arranged in the second direction, and a plurality of data lines extending along the second direction and arranged in the first direction, the sub-pixels are disposed in pixel regions surrounded by two adjacent scan lines and two adjacent data lines, and each sub-pixel includes a pixel electrode.
Preferably, the pixel array further comprises a plurality of common electrodes extending along the first direction and arranged along the second direction; the common electrode is reused as a second touch electrode and forms mutual capacitance with the first touch electrode.
Preferably, the pixel electrode includes a plurality of sub-pixel electrodes extending along the second direction and arranged in the first direction, the touch unit further includes a plurality of dummy electrodes extending along the second direction and arranged in the first direction, and projections of the plurality of sub-pixel electrodes and the dummy electrodes on a plane where the pixel array is located are staggered.
Due to the fact that the projection of the dummy electrodes on the plane where the pixel array is located and the sub-pixel electrodes are arranged in a staggered mode, the difference between light transmittance of the area where the pixel electrodes are arranged and the light transmittance of the area where the dummy electrodes are arranged is reduced, and therefore visibility of the touch display device is reduced.
Preferably, the projection of a plurality of the dummy electrodes on the plane of the pixel array is located in a pixel area, and the width of the slits between the dummy electrodes located at the edge of the pixel area is greater than the width of the slits between the dummy electrodes located in the middle of the pixel area.
Due to the fact that the dummy electrodes located in one pixel area are orthographically projected, the width of the slits between the dummy electrodes located at the edges of the pixel area is larger than that of the slits between the dummy electrodes located in the middle of the pixel area, so that the difference between the transmittance at the edges of the pixel area and the transmittance in the middle of the pixel area is reduced, and the visibility of the touch display device is reduced.
An embodiment of the present invention provides an electronic device, including any one of the touch display devices described above.

It should be noted that, in one touch electrode, the length of the first slits near the two ends along the second direction is preferably greater than the length of the first slits near the middle, so as to make up for the problem that the visibility of the touch display device is more obvious due to the transmittance at the two ends of the sub-pixel being lower than the transmittance in the middle.
Preferably, the pixel array comprises a plurality of rows of sub-pixels arranged along the first direction and a plurality of columns of sub-pixels arranged along the second direction, the sub-pixels in a column have the same color, and the sub-pixels in a row have at least two different colors.
When the sub-pixels have three different colors of red R, green G, and blue B, they may be arranged in R, G, B, R, G, B … … form as shown in fig. 4(a), or in R, G, R, B, G, B … … form, as long as the color of the sub-pixels adjacent to each other in the first direction is different, and thus the description is omitted here.

Preferably, the sub-pixels in a row have three different colors, red, green and blue, respectively, and are arranged in a cycle in the first direction; alternatively, the sub-pixels in a row have four different colors, red, green, blue, white, respectively, and are arranged cyclically in the first direction.

Preferably, the pixel array further comprises a plurality of common electrodes extending along the first direction and arranged along the second direction; the common electrode is reused as a second touch electrode and forms mutual capacitance with the first touch electrode.
Specifically, the common electrode is reused as a second touch electrode, the second touch electrode may be a driving electrode or an induction electrode, the second touch electrode and the first touch electrode form a mutual capacitance, the first touch electrode may be the induction electrode or the driving electrode, and touch detection is realized through a change of the mutual capacitance.

As shown in fig. 6(a), in the case that the projection of the dummy electrode 60 on the plane where the pixel array is located is staggered with the sub-pixel electrodes 61, the dummy electrode 60 is disposed in a hollow area surrounded by the first touch electrodes and arranged along a second direction, and the second direction is perpendicular to the first direction, which is the best case for reducing the visibility of the touch display device.
It should be noted that the projection of the dummy electrode on the plane of the pixel array and the sub-pixel electrode may also be overlapped, as shown in fig. 6(b), the projection of the dummy electrode 60 on the plane of the pixel array and the sub-pixel electrode 61 are overlapped. Or the projection of the dummy electrode 60 on the plane where the pixel array is located and the sub-pixel electrodes may be overlapped with each other or staggered with each other, as long as the visibility of the touch display device can be reduced, which is not described herein again.
The dummy electrode 60 may extend in the second direction, may extend in the first direction, as shown in fig. 6(c), or may extend in any direction other than the first direction or the second direction, as shown in fig. 6 (d).

As shown in fig. 6(a), taking the color of the sub-pixel as blue B as an example, the orthogonal projection of the dummy electrode 60 in the pixel array is located in one sub-pixel B, and the width H1 of the slit near the edge area of the sub-pixel B of the slits extending in the second direction of two adjacent dummy electrodes is greater than the width H2 of the slit near the middle area, which compensates for the fact that the transmittance on both sides of the sub-pixel B is higher than the transmittance in the middle, which results in the transmittance on both sides of the dummy electrode being higher than the transmittance in the middle, thereby reducing the visibility of the touch display device.
An embodiment of the present invention further provides an electronic device, including any of the touch display devices described above.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention.
