Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a breakpoint repair circuit, method, apparatus, device and medium for display panels. Background Technology

[0002] During the production of display panels, defective products may exist due to various reasons, with some data lines having breaks. These broken data lines appear as vertical dark lines when the panel is lit, requiring scrapping. This indirectly increases costs and reduces production efficiency. To repair these breaks, repair lines can be installed on the display panel to allow the section of the broken data line disconnected from the data drive unit to light up. However, simply introducing repair lines for break repair results in a longer data signal transmission path after repair, leading to a larger RC load. This causes a delay in the waveform rise in the time domain, resulting in insufficient charging of the sub-pixel units on the repair line during the charging time. Consequently, the repaired section will appear as a dark line, affecting the overall image quality of the display panel.

[0003] In other words, even after repairing the breakpoints using only the repair line, the entire repaired section may still appear as a dark line.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustration and has no specific meaning in itself. Therefore, "module" and "part" may be used interchangeably.

[0032] During the production of display panels, defective products may exist due to various reasons, with some data lines having breaks. These broken data lines appear as vertical dark lines when the panel is lit, requiring scrapping. This indirectly increases costs and reduces production efficiency. To repair these breaks, repair lines can be installed on the display panel to allow the section of the broken data line disconnected from the data drive unit to light up. However, simply introducing repair lines for break repair results in a longer data signal transmission path after repair, leading to a larger RC load. This causes a delay in the waveform rise in the time domain, resulting in insufficient charging of the sub-pixel units on the repair line during the charging time. Consequently, the repaired section will appear as a dark line, affecting the overall image quality of the display panel.

[0033] In other words, even after repairing the breakpoints using only the repair line, the entire repaired section may still appear as a dark line.

[0034] To address the problems mentioned in the background art, according to one aspect of an embodiment of this application, a breakpoint repair method for a display panel is provided, such as... Figure 1 As shown, it includes:

[0035] Step 101: If a break is detected in the display panel, connect the repair cable;

[0036] Step 103: Adjust the signal gain entering the repair line through a gain circuit, wherein the gain circuit is located on a circuit board outside the display panel.

[0037] Step 105: Connect a high-pass filter to the repair line and compensate for signal attenuation on the repair line through the high-pass filter.

[0038] This application can be used for breakpoint repair in LCD (Liquid Crystal Display) or OLED (Organic Light-Emitting Diode) display panels.

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

[0040] However, simply repairing the signal by using a repair line increases the transmission path of the data signal, leading to a larger RC load. Its low-pass characteristic causes the attenuation of the high-frequency part of the signal to be much greater than that of the low-frequency part. This is reflected in the time domain by a delay in the rise of the waveform, which causes the sub-pixel units on the repair line to be undercharged during the charging time. This results in an overall dark line in the repaired section, and the display panel after repair has a poor picture display effect. Figure 2The figure shows a charging comparison diagram of the input signal of an optional trace provided according to an embodiment of this application. As shown, the data input signal after the trace is repaired has an error compared with the ideal data input signal.

[0041] Figure 3 This is a schematic diagram of an optional display panel breakpoint repair structure according to an embodiment of this application. The entire structure includes a repair output line (i.e., repair line) after the breakpoint and a normal COF (Chip On Film) output line (i.e., ordinary data line) before the breakpoint. The high-pass filter is composed of RC parallel circuits and is located at the top end of the data line. The "repair" box in the figure represents the gain circuit.

[0042] exist Figure 3 If no gain circuit and high-pass filter are set up, the data line itself also has RC loading (resistor-capacitor loading). At high refresh rates and large-size display panels, the attenuation effect is severe. Since the signal input position of the repaired data line is exactly opposite to that of the normal data line, the attenuation effect is also different. On the repaired data line, the attenuation gradually decreases from point C to point B', but on the normal data line, the attenuation gradually increases from point C to point B'. The repaired segment will show an uneven vertical line with the sky side bright and the ground side dark.

[0043] During signal transmission through the repair line, signal strength may attenuate due to impedance changes or other factors. Therefore, a gain circuit is needed to adjust the signal gain entering the repair line. This gain circuit is located on a circuit board outside the display panel and, by adjusting the gain, ensures that the signal maintains sufficient strength when transmitted to the display panel.

[0044] The signal in the repair line may be affected by attenuation during transmission. Therefore, in order to counteract this attenuation, this application also incorporates a high-pass filter 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] This application improves the overall gain by setting a high-pass circuit in the in-plane architecture and a gain circuit outside the plane, which balances the high-frequency component attenuation caused by the traces in the repair section, reduces waveform delay, and solves the problem of overall dark lines in the repaired section caused by insufficient pixel charging.

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

[0047] Specifically, the input terminal of the gain circuit is connected to the driving circuit of the display panel, enabling the gain circuit to receive the original signal output by the driving circuit. The output terminal 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 transmitting signals to the display panel.

[0048] When the input of the gain circuit receives the original signal from the drive 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 of the gain circuit, enabling the signal to be transmitted in an enhanced state in the repair line, thereby effectively restoring the normal operation of the display panel.

[0050] By adjusting the signal gain entering the repair line through a gain circuit, it can be ensured that even if a break 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 filter is incorporated into the repair line, comprising: setting an access point every preset number of columns on the repair line, wherein each access point is used to connect to the high-pass filter; calculating the component parameters corresponding to each access point based on the column number of each access point, wherein the component parameters include the resistance parameters and capacitance parameters in the high-pass filter; configuring the high-pass filter according to the component parameters of each access point, and connecting the high-pass filter to the access point.

[0052] On the repair line, an access point is set every preset number of columns. Each access point is used to connect to a high-pass filter circuit. 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 critical location.

[0053] For each access point, the corresponding component parameters are calculated based on its column number. Component parameters include the resistor and capacitor parameters in the high-pass filter stage. 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, the resistors and capacitors of the high-pass filter are configured based on the calculated component parameters. Connecting each access point to the corresponding high-pass filter according to its column number ensures that the high-pass filter at each access point can process the signal passing through the repair line in a targeted manner. The signal in the repair line can receive effective high-frequency compensation during transmission, avoiding signal degradation caused by RC effects.

[0055] Figure 4 This is a schematic diagram illustrating an optional high-pass filter circuit according to an embodiment of this application. When a broken line needs repair, a laser connects the high-pass filter circuit to the antenna side of the data line being repaired. As the horizontal distance from the broken line to the output of the gain circuit increases, the RC effect on the repair trace becomes greater. Different resistor and capacitor values ​​are set at regular intervals (20 columns in the example) to balance the impact of varying RC effects.

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

[0057] The target corner frequency is a key parameter of a high-pass filter, which determines how the filter processes signals. Signal frequencies below the target corner frequency will be attenuated, while frequencies above or equal to the target corner frequency will be retained.

[0058] Specifically, the high-pass filter detects the frequency of the input signal on the repair line entering the high-pass filter stage. If the detected signal frequency is lower than the target cutoff frequency, the high-pass filter stage attenuates the input signal, thus removing or reducing the amplitude of low-frequency signals and minimizing the impact of potential low-frequency noise on the display signal. If the signal frequency is greater than or equal to the target cutoff frequency, the high-pass filter stage directly outputs the input signal without attenuation. This is because high-frequency signals are usually the part that needs to be preserved; after passing through the high-pass filter stage, they will continue to be transmitted to ensure the clarity and stability of the display effect.

[0059] By using a high-pass filter, the signals in the repair line can be processed in a targeted manner, ensuring that low-frequency interference is effectively attenuated while useful high-frequency signals are preserved 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 further includes: calling the gain adjustment stage and connecting the gain adjustment stage to the gain circuit; generating a pulse width modulation waveform through the timing controller in the gain adjustment stage, 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 (PWM) waveform is generated by the timing controller in the gain adjustment stage. The duty cycle of the PWM waveform is the ratio of the high-level duration to the period. The duty cycle is adjusted according to the number of charging rows on the display panel and is directly proportional to the number of charging rows, meaning that the more charging rows there are, the larger the duty cycle.

[0062] The signal gain of the gain circuit can be adjusted in real time by changing the duty cycle of the pulse width modulation waveform. The duty cycle of the pulse width modulation waveform directly affects the amplification of the signal by the gain circuit. Therefore, adjusting the duty cycle of the pulse width modulation waveform can dynamically adjust the signal gain to keep it consistent with the requirements of the display panel.

[0063] Figure 5 This is a schematic diagram of an optional gain circuit provided according to an embodiment of this application. The gain circuit is actually a non-inverting proportional amplifier circuit, as shown in the figure. The gain factor is 1 + (R4 / R3), which can be adjusted according to actual needs. The real-time gain adjustment stage in the figure is the gain adjustment stage provided in this application. Its circuit consists of R1, R2, R5, and C1. R1 and R2 are isolation stages to ensure circuit stability. Depending on 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 every certain number of rows (e.g., 20 rows). After passing through the low-pass filter stage composed of R5 and C1, a DC signal proportional to the current number of charging rows is obtained. This signal enters point P and changes the potential of point P, thereby fine-tuning the gain of Vrepair out in real time. This ensures that the signal gain of the repaired segment gradually decreases slightly from point C to point B', consistent with the performance of the normal data line, thus eliminating the uneven brightness phenomenon.

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

[0065] Figure 7 This is a signal comparison diagram of an optional breakpoint repair according to an embodiment of this application. The diagram includes the change state of the input signal at the repaired end under four conditions: the change state of the ideal signal, the change state of the signal with the overall gain set (close to the ideal signal), the change state of the signal with high frequency component attenuation after the repaired trace, and the change state of the signal with low frequency component balanced after high-pass filtering.

[0066] This application discloses a method for repairing breakpoints in a display panel, comprising: connecting a repair line when a breakpoint is detected in the display panel; adjusting the signal gain entering the repair line using a gain circuit, wherein the gain circuit is disposed on a circuit board outside the display panel; and connecting a high-pass filter in the repair line to compensate for signal attenuation on the repair line. By introducing a gain circuit to adjust the signal gain on the repair line and by using a high-pass filter to compensate for signal attenuation on the repair line, the method suppresses the possibility of uneven brightness in the repaired segment and solves the problem of overall dark lines appearing in the repaired segment after breakpoint repair using a repair line.
