[0040] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the technical solutions of this disclosure, and not all embodiments. Based on the embodiments recorded in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the technical solutions of this disclosure.
[0041] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.
[0042] In related technologies, with the continuous development of Micro LED display technology, in order to improve the display brightness of Micro LED and reduce power consumption during the display process, the pixel driving circuit of Micro LED has become more and more complex, and the corresponding driving voltage requirements are also increasing. The driving capability of conventional source driving circuits can no longer meet the driving requirements of Micro LED.
[0043] The preferred embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.
[0044] See Figure 1 and Figure 2 As shown in the embodiments of this application, a display device includes: a source driving circuit, multiple level conversion circuits, and multiple data lines.
[0045] In related technologies, the source driving circuit in a display device generates a data voltage, which is then output through an output terminal and provided to the data lines. Since there are multiple data lines, the source driving circuit also has multiple output terminals, so that one output terminal is connected to one data line, and another output terminal provides a data voltage to the connected data line. However, the voltage value of the aforementioned data voltage is relatively small and cannot meet the driving requirements of pixel driving circuits related to Micro LEDs.
[0046] In this embodiment of the disclosure, the source drive circuit includes multiple output terminals, and one output terminal is connected to at least one data line through at least one level conversion circuit.
[0047] In this embodiment of the disclosure, after the source driving circuit generates the data voltage, it outputs the data voltage through the output terminal and provides it to the level conversion circuit. The level conversion circuit performs operations such as boosting the data voltage, so that the voltage of the data voltage output by the level conversion circuit to the data line meets the driving requirements of the pixel driving circuit related to Micro LED.
[0048] It should be noted that, in one embodiment, one output terminal of the source drive circuit can be connected to a level conversion circuit. The output terminal of the level conversion circuit provides the boosted data voltage to the connected data line. Since there are multiple data lines, multiple level conversion circuits are also required.
[0049] For example, see Figure 1 As shown, the output terminal 1 of the source driver circuit is connected to the level conversion circuit 1, and the level conversion circuit 1 is connected to the data line 1; the output terminal 2 of the source driver circuit is connected to the level conversion circuit 2, and the level conversion circuit 2 is connected to the data line 2; the output terminal 3 of the source driver circuit is connected to the level conversion circuit 3, and the level conversion circuit 3 is connected to the data line 3... the output terminal n of the source driver circuit is connected to the level conversion circuit n, and the level conversion circuit n is connected to the data line n.
[0050] In another embodiment, one output of the source drive circuit can be connected to at least two level conversion circuits, and at least two boosted data voltages are provided to the connected data lines through at least two outputs of the at least two level conversion circuits. That is, one output of the source drive circuit corresponds to multiple outputs of the at least two level conversion circuits.
[0051] For example, see Figure 2 As shown, the output terminal 1 of the source driver circuit is connected to level conversion circuits 11, 12, ..., 1n. Level conversion circuits 11, 12, ..., 1n are connected to data lines 1, 2, ..., n, respectively. The output terminal n of the source driver circuit is connected to level conversion circuits m1, m2, ..., mn. Level conversion circuits m1, m2, ..., mn are connected to data lines m, m+1, ..., m+n, respectively.
[0052] The level shifting circuit is configured to output the data voltage to the data line in response to the data voltage at the output terminal being less than the voltage threshold, and to boost the data voltage and output it to the data line in response to the data voltage at the output terminal being greater than the voltage threshold.
[0053] During implementation, the level conversion circuit has two operating modes. In one mode, when the data voltage at the output of the source driver circuit is less than the voltage threshold, the level conversion circuit does not have the ability to increase the voltage and directly provides the data voltage provided by the source driver circuit to the data line. In the other mode, when the data voltage at the output of the source driver circuit is greater than the voltage threshold, the level conversion circuit has the ability to increase the voltage, that is, the level conversion circuit increases the data voltage provided by the source driver circuit and provides it to the data line.
[0054] See Figure 3 As shown, the level conversion circuit is connected to the first power supply voltage terminal U1. The level conversion circuit is further configured to output the voltage of the first power supply voltage terminal U1 as the boosted data voltage to the data line in response to the data voltage at the output terminal being greater than the voltage threshold. The voltage of the first power supply voltage terminal U1 is greater than the data voltage.
[0055] It should be noted that the level conversion circuit is connected to the first power supply voltage terminal U1. The voltage of the first power supply voltage terminal U1 is used as the boosted data voltage and output to the data line. That is, the level conversion circuit boosts the data voltage provided by the source drive circuit to the voltage of the first power supply voltage terminal U1 and then provides it to the data line. For example, the voltage of the first power supply voltage terminal U1 is one of 36V, 28V, 24V or 20V.
[0056] See Figure 4 As shown, an output terminal is connected to at least two data lines via at least two level conversion circuits, and the voltages of at least two first power supply voltage terminals connected to the at least two level conversion circuits are different.
[0057] Corresponding to the other embodiment described above, when one output terminal of the source drive circuit can be connected to at least two level conversion circuits, the voltage of the first power supply voltage terminal U1 connected to each level conversion circuit is different. For example, the voltage of the at least two first power supply voltage terminals U11, U12...U1n can be one of 36V, 28V, 24V, or 20V. Thus, each level conversion circuit can increase the data voltage to voltage values such as 36V, 28V, 24V, or 20V.
[0058] The circuit structure of the level conversion circuit is described in detail below. Please refer to [link / reference]. Figure 3 As shown, the level conversion circuit includes: a switching transistor Q1, a first resistor R1, and a second resistor R2.
[0059] The first terminal of the switching transistor Q1 is connected to the output terminal, the control terminal of the switching transistor Q1 is connected to the first terminal of the first resistor R1, and the second terminal of the switching transistor Q1 is connected to the first terminal of the second resistor R2.
[0060] The second terminal of the first resistor R1 is connected to the second power supply voltage terminal U2.
[0061] The first end of the second resistor R2 is connected to the first power supply voltage terminal U1.
[0062] Depend on Figure 3 It can be seen that the control terminal of switching transistor Q1 is connected to the second voltage source via the first resistor R1, the first terminal of switching transistor Q1 is connected to the output terminal of the source drive circuit, and the second terminal of switching transistor Q1 is connected to the first voltage source via the second resistor R2. The second voltage source can provide a voltage threshold, for example, 8V, to the control terminal of switching transistor Q1. It should be further noted that the voltages at both the first and second power supply terminals can be generated by a power supply module, and this power supply module and the source drive circuit can be simultaneously located on the first circuit board.
[0063] During implementation, when the voltage difference between the voltage threshold and the aforementioned data voltage is greater than or equal to the turn-on voltage Vth of the switching transistor Q1, the switching transistor Q1 is turned on, and the data voltage is output to the data line through the turned-on switching transistor Q1.
[0064] During implementation, when the voltage difference between the voltage threshold and the aforementioned data voltage is less than the turn-on voltage Vth of the switching transistor Q1, the switching transistor Q1 is turned off, and the data voltage cannot be output to the data line through the turned-off switching transistor Q1. In this case, the voltage of the first power supply voltage terminal U1 is output through the second resistor R2 and supplied to the data line.
[0065] It should be noted that the voltage at the first power supply voltage terminal U1 will inevitably be attenuated by the second resistor R2. Therefore, the voltage output through the second resistor R2 will be lower than the voltage at the first power supply voltage terminal U1. Based on this, the voltage at the first power supply voltage terminal U1 can be set higher during implementation. For example, when the desired boosted data voltage is 36V, the voltage at the first power supply voltage terminal U1 can be set to 37V or 38V, etc.
[0066] In addition, see Figure 3 As shown, the level conversion circuit also includes: a first capacitor C1.
[0067] The first terminal of the first capacitor C1 is connected to the first terminal of the first resistor R1, and the second terminal of the first capacitor C1 is connected to the second terminal of the first resistor R1.
[0068] In this embodiment, the first capacitor C1 is connected across the two ends of the first resistor R1, thereby playing a filtering role.
[0069] After introducing the electrical signal transmission relationship between the level conversion circuit, data lines, and source drive circuit, the relative positional relationship between the level conversion circuit, data lines, and source drive circuit will be introduced below.
[0070] See Figure 5 As shown, in the first case: the display device includes a display panel, multiple level conversion circuits and multiple data lines are all located on the display panel.
[0071] In this embodiment, when multiple level conversion circuits and multiple data lines are all disposed on the display panel, the multiple data lines are typically arranged in different columns and evenly distributed in the display area of the display panel. The multiple level conversion circuits are typically disposed in the non-display area of the display panel, such as the fan-out area, thereby improving the display effect of the display panel.
[0072] See Figure 5 As shown, the above-mentioned display device also includes a first circuit board.
[0073] The source drive circuit is located on the first circuit board, and the source drive circuit is connected to the level conversion circuit through the first circuit board.
[0074] Unlike the aforementioned placement of multiple level conversion circuits and data lines, in this case, the source driver circuit is located on the first circuit board, and is connected to the level conversion circuit via the first circuit board. Example 1: The output terminal of the source driver circuit is connected via a wire in the first circuit board to the solder point of the first terminal of the switching transistor Q1 in the level conversion circuit located in the display panel. Example 2: A wire extends from the output terminal of the source driver circuit into the first circuit board, and another wire extends from the first terminal of the switching transistor Q1 in the level conversion circuit into the display panel. These two wires are connected, thereby achieving the electrical connection between the source driver circuit and the level conversion circuit.
[0075] See Figure 6 As shown, in the second case: the display device includes a display panel and a first circuit board.
[0076] Multiple data lines are located on the display panel, and multiple level conversion circuits are located on the first circuit board. The level conversion circuits are connected to the data lines through the first circuit board.
[0077] The source drive circuit is located on the first circuit board, and the source drive circuit is connected to the level conversion circuit through the first circuit board.
[0078] In this embodiment, when multiple data lines are disposed on the display panel, these multiple data lines are typically arranged in different columns and evenly distributed in the display area of the display panel. The multiple level conversion circuits and source drive circuits are all disposed in the first circuit board. Thus, the source drive circuit is connected to the level conversion circuit through the first circuit board, and the level conversion circuit is then connected to the data lines through the first circuit board.
[0079] Example 3: The source drive circuit and the level conversion circuit are connected via circuit traces or wires between solder points on the first circuit board. The data line is connected via solder points on the display panel to the wire corresponding to the first terminal of the switching transistor Q1 in the level conversion circuit located on the first circuit board. Example 4: A wire extends from the data line in the display panel, and another wire extends from the first terminal of the switching transistor Q1 in the level conversion circuit on the first circuit board. These two wires are connected to achieve the electrical connection between the data line and the level conversion circuit.
[0080] In addition, see Figure 7 As shown, the display device also includes a timing controller and a shift register unit. The timing controller is located on the first circuit board, and the shift register unit is located on the display panel.
[0081] The timing controller includes an external output terminal, which is connected to the shift register unit through a level conversion circuit.
[0082] The level conversion circuit is configured to output the GOA timing signal to the shift register unit in response to the GOA timing signal at the external output terminal being less than the voltage threshold, and to boost the GOA timing signal and output it to the shift register unit in response to the GOA timing signal at the external output terminal being greater than the voltage threshold.
[0083] In order to control the scanning of the grid lines in the display panel, the display device also includes a timing controller in the related art. The timing controller is used to generate a GOA timing signal, which is provided to the shift register unit to cause the shift register unit to start working.
[0084] To enhance the driving capability of the aforementioned GOA timing signal, in this embodiment, the output terminal of the timing controller is connected to the shift register unit via a level conversion circuit. Specifically, the level conversion circuit boosts the GOA timing signal before outputting it to the shift register unit. The specific connection is similar to that of the source drive circuit and level conversion circuit described above. However, it should be noted that the level conversion circuit here only needs to include one output port. After adding a level conversion circuit to the timing controller, the first terminal of the switching transistor Q1 in the level conversion circuit is connected to the output terminal of the timing controller. The specific circuit structure of the newly added level conversion circuit will not be described in detail here.
[0085] The operation of the level conversion circuit is similar to the data voltage boosting process. During implementation, when the GOA timing signal at the external output terminal is less than the voltage threshold, the switching transistor Q1 in the level conversion circuit is turned on, outputting the GOA timing signal to the shift register unit. When the GOA timing signal at the external output terminal is greater than the voltage threshold, the switching transistor Q1 in the level conversion circuit is turned off, boosting the GOA timing signal and outputting it to the shift register unit. The voltage after the GOA timing signal is boosted is the voltage value of the first power supply voltage terminal U1 after passing through the second resistor R2.
[0086] Based on the same inventive concept, this disclosure provides a driving method for a display device described in any of the above claims, see reference. Figure 8 As shown, it includes:
[0087] Step 201: The source drive circuit outputs data voltage to the connected level conversion circuit through its output terminal.
[0088] In this embodiment, the source drive circuit is connected to the level conversion circuit via its output terminal. Thus, after the source drive circuit generates a data voltage, it further outputs the data voltage to the level conversion circuit. Typically, the source drive circuit is located on a first circuit board, and the level conversion circuit is located on the first circuit board or in the display panel.
[0089] Step 202: The level conversion circuit outputs the data voltage to the data line in response to the data voltage being less than the voltage threshold, or in response to the data voltage being greater than the voltage threshold, it boosts the data voltage and outputs it to the data line.
[0090] When the data voltage is supplied to the level conversion circuit, if the data voltage is less than the voltage threshold, the switching transistor Q1 in the level conversion circuit is turned on, thereby outputting the data voltage to the data line through the turned-on switching transistor Q1; if the data voltage is greater than the voltage threshold, the switching transistor Q1 in the level conversion circuit is turned off, and the voltage of the first power supply voltage terminal U1 is used as the boosted data voltage and output to the data line through the second resistor R2.
[0091] In summary, the display device and driving method provided in this embodiment include: a source driving circuit, multiple level conversion circuits, and multiple data lines. The source driving circuit includes multiple output terminals, and each output terminal is connected to at least one data line through at least one level conversion circuit. The level conversion circuit is configured to output a data voltage to the data line in response to a data voltage at the output terminal being less than a voltage threshold, and to boost the data voltage and output it to the data line in response to a data voltage at the output terminal being greater than a voltage threshold. The arrangement of the multiple level conversion circuits can effectively improve the driving capability of the source driving circuit, thereby meeting the display requirements of the screen.
