[0018] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0019] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0020] Before describing the technical solutions provided in the embodiments of this application, in order to facilitate understanding of the embodiments of this application, this application first specifically explains the problems existing in the related technologies: In existing display technologies, especially for irregularly shaped displays (such as circular, teardrop, and other non-square panels) or very regular-shaped panels, the irregular shape of the display panel results in significant differences in the length of each data line. Consequently, the RC loading of different data lines varies. When the driver integrated circuit (DIC) transmits signals to the data lines through its signal output terminal, these different RC loadings affect the phase margin (PM) of the signal. Specifically, data lines with a larger RC value have a larger PM value compared to data lines with a smaller RC value. A data line with a larger PM value can cause signal delay or oscillation during data transmission, resulting in uneven brightness on the displayed screen and a poor display effect.

[0021] Based on this, embodiments of this application provide a display device and an electronic device that can solve the above-mentioned problems. The following is a detailed description of a display device provided by an embodiment of this application.

[0022] In some embodiments, such as Figure 1 As shown, this application embodiment provides a display device 100, which may include: Display panel 10 includes multiple data cables 101; The driver chip 20 includes multiple signal output terminals and at least one load compensation structure 201. The signal output terminals are electrically connected to the data line 101, and at least one signal output terminal is electrically connected to the load compensation structure 201. The parameters of the load compensation structure 201 are adjustable.

[0023] Here, the aforementioned display panel 10 is an irregularly shaped display panel 10, such as a circular, teardrop, or triangular shape. The aforementioned display panel 10 is provided with multiple data lines 101, and there are at least two data lines 101 of different lengths. The number of pixels connected by the at least two data lines 101 of different lengths is different, and their corresponding resistive-capacitive loads are also different.

[0024] like Figure 1 Taking a circular display panel as an example, the display device also includes a driver chip 20. The driver chip can be integrated around the display panel and includes at least two signal output terminals. The at least two signal output terminals can be electrically connected to at least two data lines 101 one by one.

[0025] At the same time, such as Figure 1 middle, Figure 2 This is a schematic diagram of an exemplary driver chip 20. Within this driver chip 20, a load compensation structure 201 can be provided for at least one signal output terminal. For example, taking a display panel 10 that includes two data lines 101 of different lengths, the load compensation structure 201 can be provided only for the signal output terminal connected to the shorter data line 101. Alternatively, a corresponding load compensation structure 201 can be provided for each signal output terminal corresponding to both data lines 101. Based on the aforementioned load compensation structure 201, the resistive-capacitive loads corresponding to different data lines 101 can be compensated, ensuring that the resistive-capacitive loads of different data lines 101 remain consistent after compensation by the load structure.

[0026] In some examples, the load compensation structure 201 described above may include a resistor or a capacitor. For example, a resistor may be connected in series at the signal output terminal of the driver chip 20, or in addition to a series resistor, a capacitor may be connected in parallel between the signal output terminal and the reference voltage terminal at the signal output terminal of the driver chip 20.

[0027] This embodiment of the application, by setting a load compensation structure inside the driver chip, can compensate for the resistive and capacitive load of the data lines based on the aforementioned load compensation structure, making the resistive and capacitive load of each data line more consistent. This avoids display defects such as screen splitting, color shift, or uneven brightness that occur in irregularly shaped display panels, and improves display uniformity. At the same time, the parameters of the load compensation structure set inside the driver are adjustable, allowing the driver chip to adapt to display panels of different shapes by adjusting the parameters, and no structural adjustments to the display panel are required during adaptation, shortening the debugging cycle of the display panel 10.

[0028] In some embodiments, such as Figure 2 As shown, the load compensation structure 201 of the driver chip includes an adjustable resistor, and at least one signal output terminal is electrically connected to the data line 101 through the adjustable resistor.

[0029] like Figure 2In the above-mentioned load compensation structure 201, an adjustable resistor may be included, that is, the signal output terminal may be electrically connected to the data line 101 through the adjustable resistor. During the display process of the display panel 10, the data signal output from the signal output terminal is transmitted to the data line 101 through the adjustable resistor.

[0030] Here, during the debugging process of the display device, the resistance value of the adjustable resistor corresponding to each data line 101 can be determined in advance based on the number of pixels connected to each data line 101 in the actual display panel 10, and the adjustable resistor inside the driver chip 20 is set to the corresponding resistance value. For example, for a data line 101 with a small number of connected pixels and a shorter length, its corresponding adjustable resistor can be increased; for a data line 101 with a large number of connected pixels and a longer length, its corresponding adjustable resistor can be decreased.

[0031] In some examples, during the debugging process of the display device, a simulation model of the display device can be established. This simulation model allows observation of the transient response waveform output by each data line 101. Based on the transient response waveform, the PM corresponding to each data line 101 can be determined, such as... Figure 3 middle, Figure 3 This is a schematic diagram illustrating the change of voltage V of a data signal over time t in one example. If the rise time of the transient response waveform is observed to be shorter than that of the standard waveform (green waveform in the figure), it is determined that the PM corresponding to that data line 101 is smaller (the PM of the red waveform in the figure is smaller), and the resistance value of the adjustable resistor can be appropriately increased. If the rise time of the transient response waveform is observed to be longer than that of the standard waveform, it is determined that the PM corresponding to that data line 101 is larger (the PM of the red waveform in the figure is smaller), and the resistance value of the corresponding adjustable resistor can be appropriately decreased. Based on the above debugging method, the resistance value of the adjustable resistor corresponding to each data line 101 is determined, and the adjustable resistor in the display device is set to the above-mentioned corresponding resistance value.

[0032] This application embodiment, by setting a load compensation structure including an adjustable resistor, can compensate for the resistive and capacitive loads of different data lines based on the adjustable resistor, so that the resistive and capacitive loads of different data lines tend to be consistent, which is beneficial to improving display uniformity.

[0033] In some embodiments, such as Figure 4 In the middle, the load compensation structure 201 includes multiple load compensation components 30, which are connected in series; the load compensation component 30 includes transistors and load compensation devices 301 connected in parallel.

[0034] During the debugging process of the display device, the number of load compensation devices 301 connected in series in the load compensation structure 201 can be changed by controlling the on / off state of different transistors. It is conceivable that when a transistor in a certain load compensation component 30 is controlled to be in the on state, its parallel-connected load compensation device 301 will be short-circuited, and that load compensation component 30 cannot participate in adjusting the RC load of the data line 101; or, when a transistor in a certain load compensation component 30 is controlled to be in the off state, its parallel-connected load compensation device 301 will be connected to the circuit, thereby adjusting the RC load of the data line 101 electrically connected to it. Here, after debugging is completed, the parameters of the compensation structure will remain unchanged in the subsequent display process, and the load of the aforementioned transistors is relatively small when they are on.

[0035] In some examples, the load compensation device 301 described above may include a resistor.

[0036] This application embodiment, by setting up the above-mentioned multiple series-connected load compensation components, allows for flexible setting of the number of connected load compensation devices through transistor control. This enables fine compensation of the resistive and capacitive loads of different data lines for different irregularly shaped display panels, thereby improving display uniformity.

[0037] In some embodiments, such as Figure 4 As shown, the load compensation component 30 includes a first component, and multiple first components are connected in series between the signal output terminal and the data line 101; the first component includes a first transistor T1 and a resistor connected in parallel.

[0038] Here, the resistors in the different first components can be fixed resistors, and the resistance values ​​of the resistors in the different first components can be the same or different. Alternatively, the multiple resistors connected in series can be adjustable resistors.

[0039] During the testing phase of the display device, the equivalent resistance of the load compensation component 30 can be adjusted by controlling the opening or closing of different first transistors T1 in the load compensation component 30 corresponding to each data line 101, so that the RC load of different data lines 101 tends to be consistent.

[0040] Based on the above-mentioned load compensation component, the embodiments of this application can directly compensate for the resistive and capacitive loads of different data lines by changing the number of series-connected resistors, so that the driver chip can adapt to display panels of different shapes. Without adjusting the structure of the display panel, the resistive and capacitive loads of different data lines tend to be consistent, thereby improving display uniformity.

[0041] In some embodiments, the circular display panel 10 is still taken as an example, such as Figure 5As shown, the load compensation structure 201 includes an adjustable capacitor, and at least one signal output terminal is coupled to a reference voltage terminal through the adjustable capacitor.

[0042] Here, during the debugging process of the display device, the capacitance value of the corresponding adjustable capacitor can be determined for the number of pixels connected to each data line 101 and its length, and the adjustable capacitor in the display device can be set to the aforementioned capacitance value. For example, for a data line 101 with fewer connected pixels and shorter length, the capacitance value of its corresponding adjustable capacitor can be increased; or, for a data line 101 with more connected pixels and longer length, the capacitance value of its corresponding adjustable capacitor can be decreased.

[0043] This application embodiment includes an adjustable capacitor in the load compensation structure. Based on the adjustable capacitor, the resistive and capacitive loads of different data lines are compensated, so that during the normal display process of the display panel, the display uniformity can be improved without consuming additional current of the data signal.

[0044] In some embodiments, such as Figure 6 As shown, for a load compensation component 30 including multiple series-connected components, the load compensation component 30 may include a second component, and multiple second components are connected in series between the signal output terminal and the reference voltage terminal; the second component includes a second transistor T2 and a capacitor connected in parallel.

[0045] The equivalent capacitance of the load compensation component 30 can be adjusted by controlling the opening or closing of different second transistors T2 in the load compensation component 30 corresponding to each data line 101, so that the resistive and capacitive loads of different data lines 101 tend to be consistent.

[0046] It is conceivable that the capacitors in the different second components mentioned above can be fixed capacitors, and the capacitance values ​​of the capacitors in the different second components can be the same or different; or, the capacitors in the different second components mentioned above can be adjustable capacitors.

[0047] This application embodiment, by setting a stall compensation component including a second component, can adjust the number of connected capacitors by controlling the opening and closing of the second transistor in the second component, thereby compensating for the resistive and capacitive loads of different data lines and improving display uniformity.

[0048] In some embodiments, such as Figure 7 As shown, Figure 7 A schematic diagram of another exemplary display device, such as Figure 7 In the process, the load compensation structure 201 may include both an adjustable resistor and an adjustable capacitor, and the resistive-capacitive load of the data line 101 is adjusted based on the aforementioned adjustable resistor and adjustable capacitor.

[0049] In some embodiments, such as Figure 8 As shown, Figure 8A schematic diagram of another exemplary display device, such as Figure 8 In the load compensation structure 201, multiple load compensation components 30 may be included. Each load compensation component 30 includes a first component and a second component. The first component includes a first transistor T1 connected in parallel and a resistor, and the second component includes a second transistor T2 connected in parallel and a capacitor. The number of resistors and capacitors in the circuit can be adjusted by changing the on / off state of the first transistor T1 and the second transistor T2 to provide targeted compensation for the resistive-capacitive loads of different data lines 101.

[0050] In some embodiments, the data line includes a first data line and a second data line, the signal output terminal includes a first signal output terminal and a second signal output terminal, and the load compensation structure 201 includes a first load compensation structure and a second load compensation structure; the first signal output terminal is electrically connected to the first data line and the first load compensation structure respectively, and the second signal output terminal is electrically connected to the second data line and the second load compensation structure respectively; the resistive-capacitive load of the first data line is greater than the resistive-capacitive load of the second data line; the equivalent resistive-capacitive load of the load compensation component 30 in the first load compensation structure is less than the equivalent resistive-capacitive load of the load compensation component 30 in the second load compensation structure.

[0051] Here, taking the circular display panel 10 as an example, such as Figure 7 In the display panel 10, there are a first data line, which is a long line on the right side of the figure, and a second data line, which is a short line on the left side of the figure. The length of the first data line is greater than the length of the second data line, and the number of pixels connected by the first data line is greater than the number of pixels connected by the second data line. That is, the resistive-capacitive load of the first data line is greater than the resistive-capacitive load of the second data line.

[0052] During the testing phase of the display device, for the second data line with a larger resistive-capacitive load, the equivalent resistive-capacitive load of its corresponding second load compensation structure is also larger. Conversely, for the first data line with a smaller resistive-capacitive load, the equivalent resistive-capacitive load of its corresponding first load compensation structure is smaller. The load compensation structure 201 includes, for example... Figure 7 Taking the adjustable resistor and adjustable capacitor in the first load compensation structure as an example, the resistance value of the adjustable resistor in the first load compensation structure is less than the resistance value of the adjustable resistor in the second load compensation structure, or the capacitance value of the adjustable capacitor in the second load compensation structure is less than the capacitance value of the adjustable capacitor in the second load compensation structure.

[0053] This embodiment of the application reduces the equivalent load of the first load compensation structure for the first data line with a large resistive-capacitive load by decreasing the load of the first load compensation structure. This reduces the total load after the sum of the resistive-capacitive load of the first data line itself and the equivalent resistive-capacitive load of the first load compensation structure, thus preventing signal delay caused by excessive PM due to excessive total load. Simultaneously, for the second data line, increasing the equivalent resistive-capacitive load of the second load compensation structure reduces signal oscillation caused by excessively small PM due to insufficient resistive-capacitive load of the second data line. Based on the above structure, the final display effect can be improved.

[0054] In some embodiments, the number of load compensation components 30 in the first load compensation structure is n1, and the number of load compensation components 30 in the second load compensation structure is n2, where n1 = n2.

[0055] Please refer to Figure 4 , Figure 6 or Figure 8 The number of the first and second components in the first load compensation can be set to be consistent with the number of the first or second components in the second load compensation structure. At the same time, when the display device displays, it can control most of the transistors in the first or second components in the first load to be in the conducting state. That is, the number of resistors or capacitors actually connected to the circuit in the first load compensation structure is small. Similarly, the number of resistors or capacitors actually connected to the circuit in the second load compensation structure is large.

[0056] This application embodiment, by setting a standardized and consistent layout for different load compensation structures in the driver chip, can maintain the consistency of the accuracy and range of load adjustment for different load compensation structures, which is beneficial to achieving uniform display.

[0057] In some embodiments, the parameters of the load compensation structure 201 remain unchanged during the display process on the display panel 10.

[0058] During the debugging phase of the display device, the RC load of the data line 101 is compensated by adjusting the RC load of the load compensation structure 201, thereby determining the parameters of the load compensation structure 201 corresponding to each data line 101. The determined parameters can then be programmed into the driver chip 20.

[0059] During the display phase of the display device, the driver chip 20 can read parameters from the memory, so that the load compensation structure 201 no longer makes dynamic adjustments during display.

[0060] This application embodiment achieves "one-time debugging, lifetime reuse" by eliminating the need for additional adjustment of the load compensation structure parameters during normal display, which helps maintain the stability of the display state.

[0061] In some embodiments, such as Figure 9 As shown, data line 101 includes a third data line and a fourth data line, signal output terminal includes a third signal output terminal, load compensation structure 201 includes a third load compensation structure, the third signal output terminal is connected to the third data line and the fourth data line in a time-division multiplexing manner through gating circuit 40, and the third signal output terminal is electrically connected to the third load compensation structure; the third data line (e.g. Figure 9 The resistive-capacitive load of the short data line on the left side is less than that of the fourth data line (e.g., Figure 9 The resistive-capacitive load of the third load compensation structure is the first resistive-capacitive load when the third signal output terminal is connected to the third data line; when the third signal output terminal is connected to the fourth data line, the equivalent resistive-capacitive load of the third load compensation structure is the second resistive-capacitive load; the first resistive-capacitive load is greater than the second resistive-capacitive load.

[0062] like Figure 9 In the above-mentioned selection circuit 40, there are a first switching unit S1 and a second switching unit S2. By controlling the conduction and cutoff of different switching units, the data signal output by the third signal output terminal can be transmitted to the third data line or the fourth data line at different time periods.

[0063] For example, in the first time period, controlling the first switching unit S1 to be turned on and the second switching unit S2 to be turned off can increase the equivalent RC load in the third load compensation structure, for example, turning off more transistors in the first or second component and connecting more resistors or capacitors; in the second time period, controlling the first switching unit S1 to be turned off and the second switching unit S2 to be turned on can decrease the equivalent RC load in the third load compensation structure, for example, closing more transistors in the first or second component and connecting fewer resistors or capacitors.

[0064] The embodiments of this application can reduce the number of output pins of the driver chip while maintaining driving capability, simplifying panel wiring and facilitating the achievement of narrow bezels. Simultaneously, a flexible load compensation structure is incorporated into the driver chip, eliminating the need to modify the display panel structure and enabling rapid debugging for display panels of various shapes.

[0065] In some embodiments, the equivalent RC loads of each load compensation component 30 in the third load compensation structure are equal; when the third signal output terminal is connected to the third data line, the number of transistors in the third load compensation structure that are in the off state is a first number; when the third signal output terminal is connected to the fourth data line, the number of transistors in the third load compensation structure that are in the off state is a second number; the first number is greater than the second number.

[0066] like Figure 9In the aforementioned third load compensation structure, multiple first components and second components may be included. The first component includes a first transistor T1 connected in parallel and a resistor, and the second component includes a second transistor T2 connected in parallel and a capacitor. Since the RC load of the third data line is less than that of the second data line 101, when the third signal output terminal is connected to the third data line, a larger number of transistors in the third load compensation structure can be disconnected to increase the equivalent RC load of the third load compensation module; when the third signal output terminal is connected to the fourth data line, a larger number of transistors in the third load compensation structure can be closed to reduce the equivalent RC load of the third load compensation module.

[0067] In this embodiment of the application, when the third signal output terminal is connected to different data lines, compensation is added for data lines with low impedance and capacitance loads and compensation is reduced for data lines with high impedance and capacitance loads. This achieves differentiated compensation for different data lines, which helps to eliminate signal oscillations and improve display uniformity.
