Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
In the related art, there is a full-screen including a transparent display area and a non-transparent display area, and the transparent display area can implement both a light transmission function and a display function. Wherein, photosensitive elements such as a camera, a distance sensor and the like are arranged below the transparent display area. When the transparent display area performs a light transmission function, the requirement for the light transmission performance of the transparent display area is relatively high.
In order to solve the above technical problems, embodiments of the present invention provide a display device, a display panel thereof, and an OLED array substrate, which can effectively utilize the space of the OLED array substrate to provide a gate driving unit for pixels in a transparent display area, and further can implement multi-row and multi-column pixel display in the transparent display area.
An embodiment of the present invention provides an OLED array substrate, as shown in fig. 1, including: a display area 11 and a non-display area 12 surrounding said display area 11.
As shown in fig. 1, the display area 11 includes a non-transparent display area 111 and a transparent display area 112. The non-transparent display area 111 at least partially surrounds the transparent display area 112. The non-transparent display region 111 includes first OLED pixels (not shown) arranged in an array, and the first OLED pixels arranged in an array are driven actively. The transparent display area 112 includes second OLED pixels (not shown) arranged in an array, when the second OLED pixels arranged in an array are driven, the transparent display area 112 performs a display function, and when the second OLED pixels arranged in an array are not driven, the transparent display area 112 performs a light transmission function.
As shown in fig. 1, the non-transparent display area 111 includes a shaped corner 13, and the shaped corner 13 is a non-right angle. The transparent display area 112 is opposite to the shaped corner 13 in the row direction of the second OLED pixels arranged in an array. In the non-display area 12, a first gate driving unit 14 and a second gate driving unit 15 are disposed at intervals along the irregular corner 13. Each row of the first OLED pixels is connected to the corresponding first gate driving unit 14 through the corresponding first scanning line 16, and each row of the second OLED pixels is connected to the corresponding second gate driving unit 15 through the corresponding second scanning line 17.
Since the sides of the shaped corner 13 of the non-transparent display area 111 are non-straight, the shaped corner 13 can provide more space than a right angle, so that not only the first gate driving unit 14 of the first OLED pixel in the non-transparent display area 111 but also the second gate driving unit 15 of the second OLED pixel in the transparent display area 112 can be disposed along the shaped corner 13. Since the gate driving units of the pixels in the transparent display region are not disposed under the transparent display region, the light transmittance of the transparent display region can be improved.
The beneficial effects of this embodiment include: the OLED array substrate comprises a display area and a non-display area surrounding the display area, the non-transparent display area comprises a special-shaped corner, the special-shaped corner is a non-right angle, in the non-display area, a first grid electrode driving unit and a second grid electrode driving unit are arranged at intervals along the special-shaped corner, each row of the first OLED pixels is connected to the corresponding first grid electrode driving unit through the corresponding first scanning line, and each row of the second OLED pixels is connected to the corresponding second grid electrode driving unit through the corresponding second scanning line. Therefore, the space of the OLED array substrate can be effectively utilized, the grid driving unit is provided for the pixels in the transparent display area, then multi-row and multi-column pixel display can be realized in the transparent display area, and the light transmittance of the transparent display area can be improved because the grid driving unit of the pixels in the transparent display area is not arranged below the transparent display area. Moreover, on the basis of the non-transparent display area, the display device does not occupy additional space, and is favorable for realizing a narrow frame.
In one embodiment, the driving manner of the second OLED pixels arranged in an array may be a passive manner, an active manner, or a semi-active manner. In an exemplary embodiment, the driving manner of the second OLED pixels arranged in an array is a semi-active type. The second OLED pixels arranged in an array may include two rows and columns of same-color pixels. The anodes of the pixels in the same color in the same row can be connected to the drain of the same switching transistor, the source of the switching transistor is connected to the data line, and the gate is connected to the control terminal for receiving the switching signal.
In one embodiment, as shown in fig. 2, all the first gate driving units 14 are sequentially connected in series to obtain a first gate driving circuit. IN the first gate driving circuit, the input terminal of the first gate driving unit 14 at the head end is the input terminal IN1 of the first gate driving circuit, and the output terminal of the first gate driving unit 14 at the tail end is the final output terminal OUT1 of the first gate driving circuit. And all the second gate driving units 15 are sequentially connected in series to obtain a second gate driving circuit. IN the second gate driving circuit, the input terminal of the second gate driving unit 15 at the head end is the input terminal IN2 of the second gate driving circuit, and the output terminal of the second gate driving unit 15 at the tail end is the final output terminal OUT2 of the second gate driving circuit. The last output terminal OUT1 of the first gate driving circuit is connected to the input terminal IN2 of the second gate driving circuit.
In the embodiment shown in fig. 2, in the first gate driving circuit, each first gate driving unit 14 outputs a first gate driving signal for driving the first OLED pixels of the corresponding row. Similarly, in the second gate driving circuit, each second gate driving unit 15 outputs a second gate driving signal for driving the second OLED pixels of the corresponding row. Specifically, the input terminal IN1 of the first gate driving circuit is used for receiving a set of clock signals as the signal source of the first gate driving unit 14 and the second gate driving unit 15. After receiving the clock signal, the first gate driving unit 14 at the head end of the first gate driving circuit processes the clock signal to generate a first gate driving signal corresponding to the first OLED pixel in the row, and uses the generated first gate driving signal as an input signal of the next first gate driving unit 14 to generate a first gate driving signal corresponding to the first OLED pixel in the row. The first gate driving unit 14 at the tail end may output the generated first gate driving signal to the first OLED pixels of the corresponding row and the input terminal IN2 of the second gate driving circuit. The second gate driving unit 15 at the head end of the second gate driving circuit may generate the second gate driving signal of the second OLED pixel of the corresponding row after receiving the first gate driving signal. The working principle of the second gate driving circuit is the same as that of the first gate driving circuit, and the description thereof is omitted. By connecting the second gate driving circuit and the first gate driving circuit in series, only the same group of clock signals can be used as signal sources to generate the gate driving signals of the transparent display area and the non-transparent display area, and the circuit structure is simplified.
IN another embodiment, as shown IN fig. 3, the final output terminal OUT2 of the second gate driving circuit is connected to the input terminal IN1 of the first gate driving circuit. IN this embodiment, the input terminal IN2 of the second gate driving circuit is used for receiving a set of clock signals as a signal source. The working principle of the gate driving circuit in this embodiment is similar to that of the gate driving circuit shown in fig. 2, and is not described herein again. By connecting the second gate driving circuit and the first gate driving circuit in series, only the same group of clock signals can be used as signal sources to generate the gate driving signals of the transparent display area and the non-transparent display area, and the circuit structure is simplified.
In one embodiment, the first gate driving unit and the second gate driving unit are shift registers, respectively. In an exemplary embodiment, all of the first gate driving units include a first shift register and a second shift register. All the second gate driving units comprise a third shift register and a fourth shift register. The third shift register, the first shift register, the fourth shift register and the second shift register are arranged in sequence.
The first shift register and the second shift register are connected in series to obtain the first gate driving circuit, the input end of the first shift register is the input end of the first gate driving circuit, and the output end of the second shift register is the output end of the first gate driving circuit. Or, the input end of the second shift register is the input end of the first gate driving circuit, and the output end of the first shift register is the output end of the first gate driving circuit.
And the third shift register and the fourth shift register are connected in series to obtain the second gate drive circuit. The input end of the third shift register is the input end of the second gate driving circuit, and the output end of the fourth shift register is the output end of the second gate driving circuit. Or, the input end of the fourth shift register is the input end of the second gate driving circuit, and the output end of the third shift register is the output end of the second gate driving circuit.
In the embodiment of the present invention, the connection relationship between the shift registers in the first gate driving circuit and the connection relationship between the shift registers in the second gate driving circuit may be selected according to actual requirements, and the connection relationship between the first gate driving circuit and the second gate driving circuit may also be selected according to actual requirements.
In one embodiment, the shaped corner 13 may be a rounded corner. The arc-shaped corners can provide more space for arranging the grid driving unit of the transparent display area, and the preparation difficulty is favorably reduced.
In another embodiment, as shown in fig. 4, the shaped corner 13 comprises at least three straight line segments 41, 42, 43 connected in series in sequence. The at least three straight line segments 41, 42, 43 comprise a first straight line segment 41, a second straight line segment 42 and a third straight line segment 43 which are connected in series in sequence; the first straight line segment 41 is flush with the first side edge 44 of the non-transparent display area, the third straight line segment 43 is flush with the second side edge 45 of the non-transparent display area 111, and the first side edge 44 is adjacent to the second side edge 45 and perpendicular to the second side edge 45.

When the second OLED pixels arranged in the array are driven, each of the second data lines 18 is connected to at least two corresponding first data lines 19. Because the driving mode of the second OLED pixel is passive driving, the required driving current is relatively large, and the first OLED pixel is active driving, the required driving current is relatively low, and the second OLED pixel can obtain a sufficiently large driving current by using at least two first data lines 19 to provide the driving current for the same second data line 18. In addition, the data lines of the non-transparent display area are multiplexed, and the data lines do not need to be independently arranged for the transparent display area in the display area, so that the space of the display panel can be saved, and the complexity is reduced.
Preferably, when the second OLED pixels arranged in the array are driven, each of the second data lines 18 is connected to the corresponding N first data lines 19.
