Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a voltage compensation method and system for solving crosstalk. Background Art

[0002] In traditional LCD display systems, gamma voltages are generated from VSP / VSN voltages, which are usually provided by the powerIC system. In such systems, the VSP / VSN voltages are usually fixed and do not change during use. The curve of the gamma voltage has a direct impact on the grayscale display and color white balance of the LCD panel. Once the gamma voltage is set, it is usually fixed and cannot be dynamically adjusted during the display process. This means that when the external environmental conditions or usage scenarios change, the brightness and color balance of the LCD display cannot be adjusted in real time.

[0003] The brightness of the LCD is not only determined by the gamma voltage, but also by the Vcom voltage. Specifically, the brightness of the LCD is determined by the voltage difference between the gamma voltage and Vcom. When the display screen changes from light to heavy load area, the instantaneous voltage change causes the VSP / VSN voltage to drop or rise, which in turn causes the gamma voltage to drop or rise, resulting in crosstalk on the display screen.

[0004] At present, the traditional solution to improve crosstalk is to increase the gamma output capability or add capacitors to stabilize the voltage. Increasing the gamma output capability and adding capacitors will increase the IC area and thus increase the cost. Summary of the invention

The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] In addition, in order to better illustrate the present invention, numerous specific details are provided in the following specific embodiments. It should be understood by those skilled in the art that the present invention can be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present invention.

[0041] At present, when the LCD display device switches between light and heavy load areas, the VSP / VSN voltage drops or rises due to instantaneous voltage changes, which in turn causes the gamma voltage to drop or rise, resulting in crosstalk on the display screen. The traditional solution to improve crosstalk is to increase the gamma output capability or add capacitors to stabilize the voltage. Increasing the gamma output capability and adding capacitors will increase the IC area and thus increase costs.

[0042] Example 1

[0043] Provides a voltage compensation method to solve crosstalk, refer to Figure 1 ,include:

[0044] S100, the change of VSP / VSN voltage during detection and display;

[0045] It should be noted that VSP / VSN voltage refers to the voltage signal used to drive pixels in liquid crystal display devices. Among them, VSP represents the positive scanning voltage and VSN represents the negative scanning voltage. These two voltage signals change alternately during the display process, and by controlling the voltage difference between the pixel electrode and Vcom (common electrode), the arrangement state of the liquid crystal molecules is adjusted to achieve the brightness change of the pixel. The stability and accuracy of the VSP / VSN voltage is crucial to ensure the display quality and stability of the liquid crystal display device.

[0046] In this embodiment, during the normal display process of the liquid crystal display device, the change of the VSP / VSN voltage is monitored in real time. This is achieved by setting a voltage sensor in the power supply system or driving circuit of the display device. When the VSP / VSN voltage changes, the sensor will capture the change and record the change amount. The change amount may be caused by changes in ambient temperature, power supply fluctuations or other factors.

[0047] S200, when it is detected that the change in the VSP / VSN voltage reaches a preset threshold, calculating a compensation voltage according to the change in the VSP / VSN voltage;

[0048] In the LCD display system, the change in the VSP / VSN voltage is used to determine whether voltage compensation is required. When the change exceeds the preset threshold, it is considered that the change will have a significant impact on the brightness and color balance of the LCD display, so appropriate voltage compensation measures need to be taken. The required compensation voltage is calculated according to a preset algorithm, which can be based on experimental data or a theoretical model. For example, linear interpolation, polynomial fitting or other appropriate mathematical methods can be used to calculate the corresponding compensation voltage value according to the change in the VSP / VSN voltage. The compensation voltage value will be used to adjust the Vcom voltage to offset the impact of the VSP / VSN voltage change.

[0049] S300, adjusting the Vcom voltage according to the compensation voltage.

[0050] After calculating the compensation voltage, the system adjusts the value of the Vcom voltage through the control circuit. Specifically, the control circuit increases or decreases the output value of the Vcom voltage according to the value of the compensation voltage. In this way, by adjusting the Vcom voltage in real time, the system can dynamically compensate for the brightness fluctuation and color imbalance caused by the change of the VSP / VSN voltage, thereby ensuring the stable display performance of the LCD display device under various conditions.

[0051] It should be noted that the change in the VSP / VSN voltage is a key parameter in the working process of the display device, and its manifestations are various, including but not limited to the difference in the change of the VSP / VSN voltage, the change multiple relationship of the VSP / VSN voltage, and the nonlinear relationship of the change of the VSP / VSN voltage. These changes are crucial to maintaining the stability of the display device and optimizing the display effect. For example, in one case, when the preset threshold is 5mV, if the difference in the VSP / VSN voltage is detected to be 10mV, this difference exceeds the preset threshold, and the system will immediately trigger the voltage compensation process for adjustment. In another case, if the preset threshold is set to 0.2 times, and the actual detected change multiple of the VSP / VSN voltage is 0.3 times, the voltage compensation process will also be triggered. This flexible threshold setting and multiple change monitoring methods ensure that the display device can obtain timely and effective voltage adjustment in various working environments, thereby ensuring the stability and consistency of the display effect.

[0052] In one possible embodiment, in order to improve the accuracy of adjustment and cope with different working conditions, multiple segmented thresholds are usually set, including but not limited to normal control thresholds and high-voltage power-off thresholds. The normal control threshold is used for fine-tuning under normal working conditions to ensure the stability and consistency of the display effect. The high-voltage power-off threshold is an emergency protection measure. When the VSP / VSN voltage change reaches the preset high-voltage damage threshold, the system will immediately start the high-voltage power-off mechanism. This mechanism will quickly cut off the power supply to prevent the equipment from being damaged by excessive voltage. At the same time, the system will also trigger an alarm to notify the operator to deal with it in time. The combination of this multi-segment threshold setting and the high-voltage power-off mechanism ensures the safety and stability of the display device under various working conditions and effectively extends the service life of the equipment.

[0053] Preferably, a multi-segment comparator is used to detect the VSP / VSN voltage.

[0054] In this embodiment, a multi-segment comparator circuit is set in the power supply system or driving circuit of the liquid crystal display device. The circuit is composed of multiple comparators, each of which has a different reference voltage threshold. These thresholds are set to cover the possible variation range of the VSP / VSN voltage, and there is a certain overlap area between adjacent thresholds to ensure that any slight voltage change can be accurately captured. When the VSP / VSN voltage changes, the multi-segment comparator circuit will simultaneously monitor this change and compare it with the preset reference voltage threshold. In this way, the system can accurately determine the amount of change in the VSP / VSN voltage and the direction of the change (increase or decrease). Using a multi-segment comparator for voltage detection improves the accuracy and sensitivity of detection, making compensation more accurate and effective.

[0055] In one possible embodiment, a differential amplifier is used to detect the VSP / VSN voltage. A differential amplifier is an electronic circuit specially designed to amplify the difference between two input signals. When detecting the VSP / VSN voltage, the differential amplifier can be used as a high-precision and effective measurement tool. The basic principle is to apply two voltage signals, VSP and VSN, to the two input terminals of the amplifier respectively, and then the amplifier outputs the voltage difference between the two signals. When using a differential amplifier for VSP / VSN voltage detection, first ensure that the input range of the differential amplifier can cover the expected VSP and VSN voltages. Connect VSP to one input terminal of the amplifier and VSN to the other input terminal. The differential amplifier amplifies the difference between the two voltages and generates a voltage proportional to the input difference at the output terminal. By adjusting the gain of the differential amplifier, the amplitude of the output signal can be controlled. In addition, the differential amplifier usually has a high common mode rejection ratio (CMRR), which means that it can effectively suppress the noise or interference common to the two input signals, thereby improving the accuracy of the measurement.

[0056] In another possible embodiment, a window comparator is used to detect the VSP / VSN voltage. A window comparator is an electronic circuit used to detect whether an input signal is within a predetermined voltage range. In VSP / VSN voltage detection, the window comparator can quickly and accurately determine whether the voltage exceeds or falls within the set upper and lower limits. When using a window comparator to detect the VSP / VSN voltage, first set the upper and lower threshold voltages of the comparator, and these two thresholds define a "window". Then, the VSP and VSN voltage signals are input into the window comparator. If the VSP / VSN voltage is within this window, the comparator will output a signal indicating "within the range"; if the voltage exceeds the window range, the comparator will output a signal indicating "out of range" (i.e., touching the preset threshold). The advantages of window comparators are their fast response and high sensitivity. They can react immediately to voltage changes and provide clear binary outputs (usually within the range / out of range), simplifying subsequent signal processing. In addition, by setting appropriate thresholds, window comparators can also be used as overvoltage or undervoltage protection circuits to prevent the system from being affected by voltage anomalies.

[0057] Preferably, the compensation voltage is calculated according to the change in the VSP / VSN voltage, referring to Figure 3 ,include:

[0058] S210, determining a compensation voltage according to a VSP / VSN voltage variation by searching a voltage compensation table.

[0059] In this embodiment, during the system initialization phase or the preset calibration process, the relationship between the VSP / VSN voltage variation and the corresponding compensation voltage is determined by experiments or theoretical calculations, and a voltage compensation table is established. The table records the compensation voltage values ​​required under different VSP / VSN voltage variations. These values ​​can be derived based on experimental data, empirical formulas or theoretical models to ensure the accuracy and effectiveness of compensation.

[0060] Once the change in the VSP / VSN voltage is detected, the system will search the pre-established voltage compensation table and determine the corresponding compensation voltage based on the value of the change. This search process can be implemented through interpolation, linear approximation or other mathematical methods to ensure that a relatively accurate compensation voltage value can be obtained when there is no direct corresponding change in the table. By searching the voltage compensation table to determine the compensation voltage, it is possible to quickly respond to the change in the VSP / VSN voltage and accurately compensate the Vcom voltage, thereby quickly solving the crosstalk problem of the LCD display device.

[0061] In a possible embodiment, the voltage compensation table is as follows:

[0062] VSP / VSN voltage change Compensation voltage 0V - 0.02V 0mV 0.02V - 0.06V 40mV 0.06V - 0.1V 80mV 0.1V - 0.14V 120mV ... ... 1.0V – 1.04V 1020mV

[0063] Table 1

[0064] As shown in the table above, the VSP / VSN voltage range is 0V to 1.04V. When the VSP / VSN voltage changes by 0.12V, the system obtains the voltage that needs to be compensated for the Vcom voltage as 120mV by querying the data in Table 1. It should be noted that even in the same type of display system, devices from different manufacturers may require different voltage compensation strategies due to differences in materials, processes and designs. This means that the voltage compensation table needs to be customized and optimized according to the specific display device and application environment.

[0065] Preferably, reference Figure 2 , the method further comprises:

[0066] S400, obtaining a gamma voltage according to the VSP / VSN voltage;

[0067] S410, calculating the voltage difference between the gamma voltage and the adjusted Vcom voltage, and adjusting the voltage compensation table according to the voltage difference.

[0068] It should be noted that gamma voltage is a key voltage parameter in liquid crystal display devices. VSP / VSN voltage is responsible for driving pixels and controlling the arrangement of liquid crystal molecules, while gamma voltage adjusts the light transmittance of liquid crystal molecules and affects display brightness and contrast. The precise setting of gamma voltage needs to be fine-tuned according to the changes in VSP / VSN voltage to ensure that the LCD screen can present the best visual effect under various display conditions. This synergy ensures the stability and high-quality display of liquid crystal display devices.

[0069] In the power supply system or driving circuit of the liquid crystal display device, the voltage difference between the gamma voltage and the Vcom voltage causes the liquid crystal to rotate at different angles, thus forming a difference in brightness. The corresponding gamma voltage value is calculated using the relationship between the VSP / VSN voltage and the gamma voltage determined by experience. This relationship can be linear, nonlinear or other forms of mathematical relationships, depending on the characteristics and design requirements of the liquid crystal display device.

[0070] After obtaining the gamma voltage, the system compares the voltage difference between the gamma voltage and the adjusted Vcom voltage. This voltage difference reflects the brightness state of the pixel in the liquid crystal display device. If the voltage difference is too large or too small, it will cause uneven brightness, color imbalance or crosstalk. According to the calculated voltage difference, it is judged whether the current voltage compensation is appropriate. If the voltage difference exceeds the preset allowable range, it means that the current compensation voltage is not enough to offset the impact of the VSP / VSN voltage change and needs to be adjusted. According to the value and direction (positive or negative) of the voltage difference, the corresponding entry in the voltage compensation table is adjusted to increase or decrease the value of the compensation voltage. The adjusted voltage compensation table will be used in the subsequent voltage compensation process to more accurately compensate for the brightness fluctuation and color imbalance caused by the VSP / VSN voltage change. After adjusting the voltage compensation table, the updated table is used for subsequent voltage compensation. When the change of the VSP / VSN voltage is detected again, the updated voltage compensation table is searched, the new compensation voltage is determined according to the value of the change, and the value of the Vcom voltage is adjusted through the control circuit to apply the new compensation. In this embodiment, the gamma voltage is obtained according to the VSP / VSN voltage, and then the voltage difference between the gamma voltage and the adjusted Vcom voltage is calculated, and adjustment is made according to the voltage difference. Through real-time feedback and adjustment, the accuracy and adaptability of voltage compensation are improved, thereby further optimizing the display effect of the liquid crystal display device.

[0071] Preferably, adjusting the Vcom voltage according to the compensation voltage includes:

[0072] According to the compensation voltage, the Vcom voltage is adjusted by an adjustable voltage source.

[0073] In this embodiment, after the compensation voltage is determined, the adjustable voltage source is controlled to adjust the value of the Vcom voltage. The adjustable voltage source is a power supply device that can output a variable voltage, and its output voltage can be adjusted continuously or discretely according to a control signal. In this embodiment, the adjustable voltage source is connected to the Vcom electrode of the liquid crystal display device to provide an adjusted Vcom voltage. The calculated compensation voltage value is converted into a corresponding control signal and sent to the adjustable voltage source. The adjustable voltage source adjusts its output voltage according to the received control signal, thereby changing the voltage value on the Vcom electrode. By adjusting the Vcom voltage in real time, the Vcom voltage is dynamically compensated to solve the crosstalk problem caused by the change of the VSP / VSN voltage.

[0074] In one possible embodiment, an operational amplifier is used to adjust the Vcom voltage. The operational amplifier has the characteristics of high input impedance, low output impedance, and adjustable gain, which enable it to accurately control and adjust the output voltage. When using an operational amplifier to adjust the Vcom voltage, we can do it in two ways: one is a voltage follower configuration, and the other is an inverting amplifier configuration. In the voltage follower configuration, the input of the operational amplifier is connected to the Vcom voltage source, and the output provides the adjusted Vcom voltage. In this configuration, the operational amplifier acts as a buffer that can provide a low-impedance output while keeping the output voltage approximately equal to the input voltage. In the inverting amplifier configuration, we can change the amplitude of the output voltage by adjusting the ratio of the feedback resistor, thereby achieving precise adjustment of the Vcom voltage.

[0075] Preferably, the method is applied to: a TDDI panel and a TFT-LCD panel.

[0076] Example 2

[0077] Provides a voltage compensation system to solve crosstalk, refer to Figure 4 ,include:

[0078] The data detection unit 100 is used to detect the change of the VSP / VSN voltage during display;

[0079] The data detection unit 100 continuously tracks the fluctuation of the VSP / VSN voltage through a high-precision voltage sensor or a dedicated detection circuit. Once a change in the VSP / VSN voltage is detected, the data detection unit immediately captures and records the change.

[0080] The data calculation unit 200 is used to calculate the compensation voltage according to the change of the VSP / VSN voltage when it is detected that the VSP / VSN voltage change reaches a preset threshold;

[0081] When the data detection unit 100 detects that the VSP / VSN voltage change reaches a preset threshold, the data calculation unit 200 starts to work. The data calculation unit 200 calculates the required compensation voltage according to the change of the VSP / VSN voltage by using a preset algorithm or looking up a pre-established voltage compensation table. The data calculation unit 200 is intended to determine an accurate compensation voltage value to offset the adverse effects of the VSP / VSN voltage change on the display effect.

[0082] The data processing unit 300 is used to adjust the Vcom voltage according to the compensation voltage.

[0083] The data processing unit 300 receives the compensation voltage value from the data calculation unit 200 and adjusts the Vcom voltage according to the compensation voltage value. The data processing unit 300 converts the calculated compensation voltage into a corresponding control signal through an interface with an adjustable voltage source or other circuit structure, and sends it to the relevant circuit to adjust the value of the Vcom voltage. This real-time adjustment ensures that the liquid crystal display device can quickly adapt to the change of the VSP / VSN voltage, thereby maintaining stable display performance.

[0084] Preferably, continue to refer to Figure 4 The system further comprises:

[0085] The data feedback unit 400 is used to obtain the gamma voltage according to the VSP / VSN voltage, calculate the voltage difference between the gamma voltage and the adjusted Vcom voltage, and adjust the voltage compensation table according to the voltage difference.

[0086] The data feedback unit 400 is used to continuously monitor and adjust the compensation effect. For example, by comparing the difference between the adjusted Vcom voltage and the preset ideal value, the data feedback unit 400 can fine-tune the calculation parameters of the compensation voltage or update the voltage compensation table to improve the system's adaptive ability and compensation accuracy.
