Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a breakpoint repair circuit, method, device, equipment and medium for a display panel. Background Art

[0002] In the production process of display panels, due to various reasons, there will be defective products with breakpoints in some data lines. When the panel is lit, the data line appears as a vertical dark line and needs to be scrapped, which in disguise increases cost waste and reduces production efficiency. In order to repair the breakpoint situation, a repair line can be set on the display panel, and the repair line allows the section of the broken data line that is disconnected from the data driving unit to be lit.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application and have no specific meaning. Therefore, "module" and "component" can be used interchangeably.

[0032] In the production process of display panels, due to various reasons, there will be defective products with breakpoints in some data lines. When the panel is lit, the data line appears as a vertical dark line and needs to be scrapped, which in disguise increases cost waste and reduces production efficiency. In order to repair the breakpoint situation, a repair line can be set on the display panel, and the repair line allows the section of the broken data line that is disconnected from the data driving unit to be lit. However, if only the repair line is introduced to repair the breakpoint, the transmission path of the data signal becomes longer after the repair, resulting in a larger RC load, which will cause a delay in the rise of the waveform in the time domain, causing the sub-pixel unit on the repair line to be insufficiently charged during the charging time, and the entire repaired section will appear as a dark line, thereby affecting the picture effect of the entire display panel.

[0033] That is to say, even if the breakpoint is repaired only by the repair line, the repaired segment will still have a dark line as a whole.

[0034] In order to solve the problem mentioned in the background technology, according to one aspect of an embodiment of the present application, a method for repairing a breakpoint of a display panel is provided, such as Figure 1 As shown, including:

[0035] Step 101, when a breakpoint is detected on the display panel, a repair line is connected;

[0036] Step 103, adjusting the gain of the signal entering the repair line by a gain circuit, wherein the gain circuit is arranged on a circuit board outside the display panel;

[0037] Step 105: A high-pass filter link is connected to the repair line, and the signal attenuation on the repair line is compensated by the high-pass filter link.

[0038] The present application can be used to repair breakpoints of LCD (Liquid Crystal Display) or OLED (Organic Light-Emitting Diode) display panels.

[0039] Specifically, when a breakpoint is detected on the display panel, a repair line needs to be connected, and the repair line is used to re-establish an electrical connection at the breakpoint to ensure that the signal can continue to be transmitted.

[0040] However, after being repaired only through the repair line, the transmission path of the data signal becomes longer, resulting in a larger RC load. Its low-pass characteristic makes the attenuation of the high-frequency part of the signal much greater than the attenuation of the low-frequency part. This is reflected in the delay of the waveform rise in the time domain, causing the sub-pixel units on the repair line to be insufficiently charged within the charging time, resulting in an overall dark line in the repaired section, and the display effect of the display panel after the repair is poor. Figure 2This is a charging comparison diagram of an input signal of an optional routing provided according to an embodiment of the present application. As shown in the figure, there is an error between the data input signal after the routing is repaired and the ideal data input signal.

[0041] Figure 3 This is a schematic structural diagram of an optional breakpoint repair of a display panel provided according to an embodiment of the present application, wherein the entire structure includes a repair output circuit after the breakpoint (i.e., the repair line) and a COF (Chip On Film) normal output circuit before the breakpoint (i.e., the ordinary data line), and the high-pass filtering link is composed of RC parallel connection and is arranged at the day side end of the data line, and the "repair" box in the figure is a gain circuit.

[0042] exist Figure 3 In the process, if the gain circuit and the high-pass filter are not set, then due to the RC Loading (resistance-capacitance loading) of the data line itself, the attenuation effect is serious when the display panel is at a high refresh rate and large size. Since the signal input position of the repaired data line is just opposite to that of the normal data line, the attenuation effect is also different. The attenuation from point C to point B' on the repaired data line gradually decreases, but on the normal data line, the attenuation from point C to point B' gradually increases. The repaired section will show uneven vertical lines with bright sky side and dark ground side.

[0043] When the signal is transmitted through the repair line, the signal strength may be attenuated due to changes in line impedance or other factors. Therefore, a gain circuit is needed to adjust the signal gain entering the repair line. The gain circuit is set on a circuit board outside the display panel. By adjusting the gain, it ensures that the signal still maintains sufficient strength when it is transmitted to the display panel.

[0044] The signal in the repair line may be affected by attenuation during transmission. Therefore, in order to offset this attenuation, the present application also connects a high-pass filter link in the repair line. The high-pass filter can filter out low-frequency noise and compensate for the attenuation of high-frequency signals, thereby maintaining the integrity and stability of the signal.

[0045] The present application improves the overall gain by setting a high-pass link in the in-plane architecture and a gain circuit outside the plane, thereby balancing the attenuation of high-frequency components caused by the routing of the repaired segment, reducing waveform delay, and solving the problem of overall dark lines in the repaired segment caused by insufficient pixel charging.

[0046] As an optional embodiment, the gain of the signal entering the repair line is adjusted through a gain circuit, including: connecting the input end of the gain circuit to the driving circuit of the display panel, and connecting the output end of the gain circuit to the starting point of the repair line; when the input end of the gain circuit receives the original signal output by the driving circuit, the original signal is amplified by the amplifier in the gain circuit; and the amplified original signal is transmitted to the repair line through the output end of the gain circuit.

[0047] Specifically, the input end of the gain circuit is connected to the driving circuit of the display panel so that the gain circuit can receive the original signal output by the driving circuit. The output end of the gain circuit is connected to the starting point of the repair line to ensure that the amplified signal can be transmitted to the repair line to continue to transmit the signal to the display panel.

[0048] When the input end of the gain circuit receives the original signal from the driving circuit, the amplifier in the gain circuit will amplify the original signal to compensate for the attenuation that may occur during signal transmission and ensure that the signal strength is sufficient.

[0049] The amplified original signal is transmitted to the repair line through the output end of the gain circuit, so that the signal can be transmitted in the repair line in an enhanced state, thereby effectively restoring the normal operation of the display panel.

[0050] By adjusting the gain of the signal entering the repair line through the gain circuit, it can be ensured that even if a breakpoint occurs in the display panel, the signal transmission in the repair line can still maintain sufficient strength and quality, thereby maintaining the integrity of the display.

[0051] As an optional embodiment, a high-pass filtering link is connected in the repair line, including: setting an access point every preset number of columns on the repair line, wherein each access point is used to connect the high-pass filtering link; calculating the component parameters corresponding to each access point according to the number of columns where each access point is located, wherein the component parameters include the resistance parameters and the capacitance parameters in the high-pass filtering link; configuring the high-pass filtering link according to the component parameters of each access point, and connecting the high-pass filtering link to the access point.

[0052] On the repair line, an access point is set for every preset number of columns. Each access point is used to connect a high-pass filter link. The setting of these access points can be based on specific signal transmission requirements and the physical layout of the repair line to ensure that the signal can be properly filtered at each key position.

[0053] For each access point, the corresponding component parameters are calculated according to the column number it is in. The component parameters include the resistance parameters and capacitance parameters in the high-pass filter link. When calculating the parameters, the frequency characteristics of the signal and the specific transmission conditions of the repair line need to be considered to ensure that the high-pass filter can effectively filter out low-frequency noise and compensate for the attenuation of high-frequency signals.

[0054] Specifically, according to the calculated component parameters, the resistor and capacitor of the high-pass filter link are configured. Each access point is connected to the corresponding high-pass filter link according to the column number where it is located, which can ensure that the high-pass filter link of each access point can process the signal passing through the repair line in a targeted manner, and the signal in the repair line can obtain effective high-frequency compensation during the transmission process, avoiding the signal degradation problem caused by the RC effect.

[0055] Figure 4 This is a schematic diagram of an optional high-pass filter access link provided according to an embodiment of the present application. When a line break needs to be repaired, the high-pass filter link is connected to the antenna side of the repaired data line through a laser. As the line break is farther from the output end of the gain circuit, the greater the RC comprehensive effect on the repair line. Different resistance and capacitance values ​​are set every certain number of columns (the example in the figure is 20 columns) to balance the impact of different RC effects.

[0056] As an optional embodiment, the signal attenuation on the repair line is compensated through a high-pass filtering link, including: obtaining the target turning frequency of the high-pass filtering link; detecting the signal frequency of the input signal of the repair line input to the high-pass filtering link; if the signal frequency is less than the target turning frequency, the input signal is attenuated through the high-pass filtering link and then output; if the signal frequency is greater than or equal to the target turning frequency, the high-pass filtering link outputs the input signal.

[0057] The target corner frequency is a key parameter of the high-pass filter, which determines how the filter processes the signal. The signal part with a frequency lower than the target corner frequency will be attenuated, while the part higher than or equal to the target corner frequency will be retained.

[0058] Specifically, the frequency of the input signal on the repair line entering the high-pass filtering link is detected. If the detected signal frequency is less than the target turning frequency, the high-pass filtering link will attenuate the input signal, which can remove or reduce the amplitude of the low-frequency signal and reduce the impact of possible low-frequency noise on the display signal; if the signal frequency is greater than or equal to the target turning frequency, the high-pass filtering link will directly output the input signal without attenuating it. This is because high-frequency signals are usually the part that needs to be retained. After passing through the high-pass filtering link, they will continue to be transmitted to ensure a clear and stable display effect.

[0059] Through the high-pass filtering link, the signal in the repair line can be processed in a targeted manner to ensure that low-frequency interference is effectively attenuated, while useful high-frequency signals are retained and transmitted, thereby improving the overall performance and reliability of the display panel.

[0060] As an optional embodiment, after adjusting the signal gain entering the repair line through the gain circuit, the method also includes: calling the gain adjustment link and connecting the gain adjustment link to the gain circuit; generating a pulse width modulation waveform through the timing controller in the gain adjustment link, wherein the duty cycle of the pulse width modulation waveform is proportional to the number of charging rows of the display panel; and adjusting the signal gain of the gain circuit in real time by adjusting the duty cycle of the pulse width modulation waveform.

[0061] A pulse width modulation waveform is generated by the timing controller in the gain adjustment link. The duty cycle of the pulse width modulation waveform is the ratio of the high level duration to the period. The duty cycle is adjusted according to the number of charging rows of the display panel and is proportional to the number of charging rows, which means that the more charging rows there are, the greater the duty cycle.

[0062] By adjusting the duty cycle of the pulse width modulation waveform, the signal gain of the gain circuit is adjusted in real time. The duty cycle of the pulse width modulation waveform directly affects the degree of signal amplification of the gain circuit, so adjusting the duty cycle of the pulse width modulation waveform can dynamically adjust the signal gain to keep it consistent with the needs of the display panel.

[0063] Figure 5 The present invention is a schematic diagram of an optional gain circuit access provided according to an embodiment of the present application. The gain circuit diagram is actually a common-phase proportional amplifier circuit. As shown in the figure, the gain multiple is 1+(R4 / R3), which can be adjusted according to actual needs. The real-time gain adjustment link in the figure is the gain adjustment link provided by the present application. The circuit part is composed of R1, R2, R5 and C1. R1 and R2 are isolation links to ensure the stability of the circuit. According to the current number of charging rows, TCON (timing controller) generates a PWM (Pulse Width Modulation) wave with a duty cycle proportional to the current number of charging rows. The duty cycle is increased once every certain number of rows (such as 20 rows). After passing through the low-pass filtering link composed of R5 and C1, a DC signal proportional to the current number of charging rows is obtained, and the potential of point P is changed, thereby fine-tuning the size of the Vrepair out gain in real time, ensuring that the signal gain of the repaired segment from point C to point B' gradually decreases slightly, which is consistent with the performance of the normal data line, thereby eliminating the uneven brightness.

[0064] Figure 6The following is a schematic diagram of gain adjustment of an optional pulse width modulation waveform duty cycle according to an embodiment of the present application. The pulse width modulation waveform duty cycle increases with the increase of the number of charging rows, thereby performing gain adjustment.

[0065] Figure 7 This is an optional signal comparison diagram after breakpoint repair provided according to an embodiment of the present application, which includes the changing states of the input signal at the repaired end under 4 situations, including: the changing state of the ideal signal, the signal changing state with the overall gain set (close to the ideal signal), the signal changing state with the high-frequency component attenuated after the repaired routing, and the signal changing state with the low-frequency component balanced after high-pass filtering.

By introducing a gain circuit to adjust the signal gain on the repair line, and compensating the signal attenuation on the repair line by a high-pass filter link, the possible uneven brightness of the repaired segment is suppressed, and the problem that the overall dark line of the repaired segment will still appear after the breakpoint is repaired by the repair line is solved.
