Description

Technical Field

[0001] This invention relates to the field of optoelectronic displays, and in particular to a brightness compensation driving method for a dual-gate controlled light-emitting device. Background Technology

[0002] Light-emitting devices (LEDs) are a crucial component of optoelectronic displays, emitting light to display images or information. Many LEDs work by combining electrons and holes in the light-emitting functional layer when an electric current is applied, forming excitons. These excitons recombine, releasing energy and emitting light; examples include QLEDs (quantum dot light-emitting diodes) and OLEDs (organic light-emitting diodes). These LEDs offer advantages such as rich color reproduction, high contrast, fast response time, wide viewing angles, and energy efficiency.

[0003] These light-emitting devices may experience aging during manufacturing due to process factors or long-term use, potentially leading to a decrease in luminous efficiency. This decrease in luminous efficiency results in a mismatch between the displayed grayscale and the actual grayscale, thus degrading display quality. By adjusting the carrier mobility within these light-emitting devices through gate modulation, it is possible to control both luminous brightness and luminous efficiency, thereby compensating for grayscale values ​​(brightness). Existing technologies that adjust luminous brightness and luminous efficiency through dual-gate modulation typically first adjust the gate that enhances both brightness and efficiency. Once the brightness meets the requirements, if the luminous efficiency still does not meet the requirements, the gate used to individually control luminous efficiency is then adjusted. However, the gate used to individually control luminous efficiency employs the principle of reducing carrier injection into the light-emitting layer, which slightly reduces luminous brightness while increasing luminous efficiency, making the adjustment of luminous brightness less precise. Summary of the Invention

[0004] In view of the aforementioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a brightness compensation driving method for a dual-gate regulated light-emitting device, which aims to avoid the mutual interference between the two-end regulation leading to regulation inaccuracy and to ensure that the luminous efficiency and luminous brightness meet the requirements.

[0005] To achieve the above objectives, this invention discloses a brightness compensation driving method for a dual-gate regulated light-emitting device, applied to a dual-gate regulated light-emitting device. The dual-gate regulated light-emitting device sequentially comprises: a first gate regulating electrode, a first gate insulating layer, an anode, a light-emitting functional layer, a cathode, a second gate insulating layer, and a second gate regulating electrode. The first gate regulating electrode and the second gate regulating electrode are used to apply a gate voltage relative to the anode and cathode, respectively. The gate voltage is used to construct an electric field to regulate the carrier mobility within the light-emitting unit, thereby adjusting the luminous efficiency and / or luminous brightness of the light-emitting unit. The method includes:

[0006] Step S1: Apply a first driving current corresponding to the first gray level value to the dual-gate regulated light-emitting device to obtain the actual gray level value of the dual-gate regulated light-emitting device; wherein, the first gate regulation electrode and the second gate regulation electrode are one of a full-type regulation electrode used to simultaneously regulate luminous efficiency and luminous brightness and a single-type regulation electrode used to individually regulate luminous efficiency, respectively.

[0007] Step S2: Based on the actual grayscale value and the first grayscale value, obtain the grayscale brightness difference and the current first luminous efficiency of the dual-gate modulated light-emitting device;

[0008] Step S3: Based on the actual grayscale value and the grayscale brightness difference, obtain the first gate voltage applied to the full-mode control electrode side; wherein, when the first gate voltage is applied to the full-mode control electrode side, the grayscale value displayed by the dual-gate control light-emitting device matches the first grayscale value;

[0009] Step S4: Based on the first gate voltage, obtain the first luminous efficiency enhancement of the dual-gate controlled light-emitting device by the first gate voltage; based on the first luminous efficiency and the first luminous efficiency enhancement, obtain the second luminous efficiency after applying the first gate voltage; determine whether the second luminous efficiency is greater than the preset required luminous efficiency; if yes, determine that the second gate voltage applied to the single-type controlled electrode side is zero; if no, proceed to step S5.

[0010] Step S5: Based on the preset required luminous efficiency, the actual grayscale value, and the first grayscale value, re-obtain the first gate voltage applied to the full-type control electrode and the second gate voltage applied to the single-type control electrode; wherein, the luminous efficiency increased by the first gate voltage and the luminous efficiency increased by the second gate voltage match the preset required luminous efficiency, and the luminous brightness increased by the first gate voltage and the luminous brightness decreased by the second gate voltage match the first grayscale value;

[0011] Step S6: Repeat steps S1-S5 to obtain the first gate voltage and the second gate voltage corresponding to each gray level value of the dual-gate controllable light-emitting device;

[0012] Step S7: Obtain the current display grayscale value of the dual-gate controllable light-emitting device, and drive the dual-gate controllable light-emitting device according to the first gate voltage, the second gate voltage and the driving current corresponding to the current display grayscale value.

[0013] Optionally, prior to step S1, the method further includes:

[0014] Step S201: Apply a first experimental current to the dual-gate controlled light-emitting device to make the dual-gate controlled light-emitting device be at a first reference gray level value;

[0015] Step S202: Continuously adjust the first test gate voltage of the full-type control gate, and collect the improved luminous efficiency and improved luminous brightness of the dual-gate controllable light-emitting device under different first test gate voltages; obtain the relationship between the first gate voltage, luminous efficiency improvement, and improved luminous brightness corresponding to the first reference grayscale value;

[0016] Repeat steps S201 and S202 above to obtain the relationship between the first gate voltage, luminous efficiency enhancement, and luminous brightness enhancement corresponding to each different reference gray level value.

[0017] Optionally, prior to step S1, the method further includes:

[0018] Step S301: Apply a second experimental current to the dual-gate controlled light-emitting device to make the dual-gate controlled light-emitting device operate at a second reference gray level.

[0019] Step S202: Continuously adjust the second test gate voltage of the single-type control gate, and collect the increased luminous efficiency and decreased luminous brightness of the dual-gate control light-emitting device under different second test gate voltages; obtain the relationship between the second gate voltage, the increased luminous efficiency, and the decreased luminous brightness corresponding to the second reference grayscale value;

[0020] Repeat steps S301 and S302 above to obtain the relationship between the second gate voltage, luminous efficiency improvement, and luminous brightness reduction corresponding to each different reference gray level value.

[0021] Optionally, step S3 includes:

[0022] Using the actual grayscale value as the reference grayscale value, the relationship between the first gate voltage, luminous efficiency improvement, and luminous brightness improvement is obtained.

[0023] Then, the grayscale brightness difference is substituted into the relationship between the first gate voltage, the light emission efficiency, and the light emission brightness as the required increase in luminous brightness, to obtain the first gate voltage applied to the full-type control electrode side.

[0024] Optionally, in step S4, obtaining the first luminous efficiency improvement of the dual-gate controlled light-emitting device based on the first gate voltage includes:

[0025] Substituting the first gate voltage into the relationship between the first gate voltage, luminous efficiency improvement, and luminous brightness improvement, we obtain the first luminous efficiency improvement of the first gate voltage on the dual-gate controlled light-emitting device.

[0026] Optionally, step S5 includes:

[0027] Using the actual grayscale value as the reference grayscale value, the relationship between the first gate voltage, luminous efficiency enhancement, and luminous brightness enhancement corresponding to the full-type control gate and the relationship between the second gate voltage, luminous efficiency enhancement, and luminous brightness reduction corresponding to the single-type control gate are obtained.

[0028] The first gate voltage and the second gate voltage are matched in the relationship between the first gate voltage, the luminous efficiency improvement, and the luminous brightness improvement, and the relationship between the second gate voltage, the luminous efficiency improvement, and the luminous brightness reduction, so that the dual-gate controlled light-emitting device is affected by the first gate voltage and the second gate voltage, and the luminous efficiency is improved to be greater than the preset required luminous efficiency, and the grayscale value is improved to match the first grayscale value.

[0031] Optionally, the hole mobility of the light-emitting functional layer is greater than the electron mobility, the second gate control electrode is the full-type control electrode, and the first gate control electrode is the single-type control electrode.

[0032] The beneficial effects of this invention are as follows: 1. This invention can first obtain the relationship between the gate voltage of the two gate control electrodes at various reference gray levels and the changes in luminous efficiency and luminous brightness. Then, based on these relationships, the first and second gate voltages for each gray level value are determined. The first and second gate voltages can ensure that the luminous brightness and luminous efficiency of the dual-gate controlled light emitter meet the requirements. Compared with the prior art, this invention considers the subtle influence of the gate controlling the luminous efficiency on the luminous brightness and eliminates this influence through the above method, thus improving the control accuracy. 2. This invention adjusts the luminous brightness through gate control, avoiding changes in the driving current. When multiple dual-gate controlled light emitters are working, the driving current for the same gray level remains uniform, facilitating driving.

[0033] In summary, this invention avoids the mutual interference between the two-end controls, which could lead to inaccurate control, and ensures that the luminous efficiency and luminous brightness meet the requirements, thereby effectively improving display quality and saving energy.

[0037] This invention discloses a brightness compensation driving method for a dual-gate controlled light-emitting device. Those skilled in the art can refer to the content of this document and appropriately modify the technical details to implement it. It should be particularly noted that all similar substitutions and modifications are obvious to those skilled in the art and are considered to be included in this invention. The methods and applications of this invention have been described through preferred embodiments. Those skilled in the art can obviously make modifications or appropriate changes and combinations to the methods and applications described herein without departing from the content, spirit, and scope of this invention to implement and apply the technology of this invention.

[0038] The applicant's research revealed that these light-emitting devices may experience aging during manufacturing due to process factors or long-term use, potentially leading to a decrease in luminous efficiency. This decrease in luminous efficiency results in a mismatch between the displayed grayscale and the actual grayscale, thus degrading display quality. By adjusting the carrier mobility within these light-emitting devices through gate modulation, both luminous brightness and luminous efficiency can be controlled, thereby compensating for grayscale values ​​(brightness). Existing technologies, when adjusting luminous brightness and luminous efficiency through dual-gate modulation, typically first adjust the gate that enhances both brightness and efficiency. Once the brightness meets the requirements, if the luminous efficiency still doesn't meet the requirements, the gate used to individually control luminous efficiency is then adjusted. However, the gate used for individually controlling luminous efficiency employs the principle of reducing carrier injection into the light-emitting layer, which slightly reduces brightness while increasing luminous efficiency, making brightness adjustment less precise.

[0039] Therefore, embodiments of the present invention provide a brightness compensation driving method for a dual-gate regulated light-emitting device, applied to a dual-gate regulated light-emitting device. The dual-gate regulated light-emitting device sequentially includes: a first gate regulating electrode, a first gate insulating layer, an anode, a light-emitting functional layer, a cathode, a second gate insulating layer, and a second gate regulating electrode. The first gate regulating electrode and the second gate regulating electrode are used to apply a gate voltage relative to the anode and cathode, respectively. The gate voltage is used to construct an electric field to regulate the carrier mobility within the light-emitting unit, thereby adjusting the luminous efficiency and / or luminous brightness of the light-emitting unit. Figure 1 As shown, the method includes:

[0040] Step S1: Apply a first driving current corresponding to the first gray level value to the dual-gate controlled light-emitting device to obtain the actual gray level value of the dual-gate controlled light-emitting device.

[0041] The first gate control electrode and the second gate control electrode are respectively one of a full-type control electrode used to simultaneously control luminous efficiency and luminous brightness, and one of a single-type control electrode used to individually control luminous efficiency.

[0042] It should be noted that because the two types of carriers in the light-emitting functional layer have different mobilities, injecting carriers with lower mobility will improve both luminous efficiency and brightness. Therefore, the corresponding control gate is a full-type control gate. When carriers with higher mobility flow out of the light-emitting functional layer, the luminous efficiency decreases, and the mobility of the two carriers tends to be balanced, thus improving luminous efficiency. Therefore, the corresponding control gate is a single-type control gate. However, the single-type control gate improves efficiency by removing carriers from the light-emitting functional layer, which slightly affects the brightness, causing a slight decrease (because there are more carriers with higher mobility in the light-emitting functional layer, the decrease is small). Therefore, the effect of the single-type control gate on brightness adjustment is much smaller than that of the full-type gate control, so there will be no situation where it cannot be controlled.

[0043] It is worth mentioning that when improving efficiency with a single-type gate control, electrons can flow to the energy storage capacitor, allowing the capacitor to store more electrical energy. This extends the light-emitting time of the dual-gate controlled LED, thereby improving the overall luminous efficiency. Energy storage capacitors are a commonly used design element to ensure continuous light emission in dual-gate controlled LEDs.

[0044] Step S2: Based on the actual grayscale value and the first grayscale value, obtain the grayscale brightness difference and the current first luminous efficiency of the dual-gate controlled light-emitting device.

[0045] In this specific embodiment, step S2 includes:

[0046] The grayscale brightness difference is obtained based on the actual grayscale value and the first grayscale value.

[0047] The initial luminous efficiency is obtained based on the first gray level value and the first driving current;

[0048] The first luminous efficiency is obtained based on the original luminous efficiency and the difference in grayscale brightness.

[0049] Step S3: Based on the actual grayscale value and the grayscale brightness difference, obtain the first gate voltage applied to the full-type control electrode side.

[0050] When the first gate voltage is applied to the full-type control electrode side, the grayscale value displayed by the dual-gate control light-emitting device matches the first grayscale value.

[0051] Step S4: Based on the first gate voltage, obtain the first luminous efficiency enhancement of the dual-gate controlled light-emitting device by the first gate voltage; based on the first luminous efficiency and the first luminous efficiency enhancement, obtain the second luminous efficiency after applying the first gate voltage; determine whether the second luminous efficiency is greater than the preset required luminous efficiency. If yes, determine that the second gate voltage applied to the single-type control electrode side is zero; if no, proceed to step S5.

[0052] Step S5: Based on the preset required luminous efficiency, the actual grayscale value, and the first grayscale value, re-obtain the first gate voltage applied to the full-type control electrode and the second gate voltage applied to the single-type control electrode; wherein, the luminous efficiency increased by the first gate voltage and the luminous efficiency increased by the second gate voltage match the preset required luminous efficiency, and the luminous brightness increased by the first gate voltage and the luminous brightness decreased by the second gate voltage match the first grayscale value.

[0053] It should be noted that in this embodiment of the invention, the full-type control gate can be adjusted first to improve both luminous efficiency and brightness. When the luminous brightness compensation is in place and the luminous efficiency also meets the requirements, there is no need to apply a second gate voltage. When the luminous brightness compensation is in place but the luminous efficiency is insufficient, the first and second gate voltages are recalculated based on the relationship between the gate voltage, the change in luminous efficiency, and the change in luminous brightness to ensure that both luminous brightness and luminous efficiency meet the requirements.

[0054] Step S6: Repeat steps S1-S5 to obtain the first gate voltage and the second gate voltage corresponding to each gray level value of the dual-gate regulated light-emitting device.

[0055] Step S7: Obtain the current display grayscale value of the dual-gate controlled light-emitting device, and drive the dual-gate controlled light-emitting device according to the first gate voltage, the second gate voltage and the driving current corresponding to the current display grayscale value.

[0056] In this specific embodiment, before step S1, the method further includes:

[0057] Step S201: Apply a first experimental current to the dual-gate controlled light-emitting device to make the dual-gate controlled light-emitting device operate at a first reference gray level.

[0058] Step S202: Continuously adjust the first test gate voltage of the full-type control gate, and collect the luminous efficiency and luminous brightness improvement of the dual-gate control light-emitting device under different first test gate voltages; obtain the relationship between the first gate voltage, luminous efficiency improvement, and luminous brightness improvement corresponding to the first reference gray level value;

[0059] Repeat steps S201 and S202 above to obtain the relationship between the first gate voltage, luminous efficiency enhancement, and luminous brightness enhancement corresponding to each different reference gray level value.

[0060] Furthermore, prior to step S1, the method also includes:

[0061] Step S301: Apply a second experimental current to the dual-gate controlled light-emitting device so that the dual-gate controlled light-emitting device is at the second reference gray level value;

[0062] Step S202: Continuously adjust the second test gate voltage of the single-type control gate, and collect the luminous efficiency improvement and luminous brightness reduction of the dual-gate control light-emitting device under different second test gate voltages; obtain the relationship between the second gate voltage, luminous efficiency improvement and luminous brightness reduction corresponding to the second reference grayscale value;

[0063] Repeat steps S301 and S302 above to obtain the relationship between the second gate voltage, luminous efficiency improvement, and luminous brightness reduction corresponding to each different reference gray level value.

[0064] Furthermore, step S3 includes:

[0065] Using the actual grayscale value as the reference grayscale value, the relationship between the first gate voltage, luminous efficiency improvement, and luminous brightness improvement is obtained.

[0066] Then, the grayscale brightness difference is substituted into the relationship between the first gate voltage, the light emission efficiency, and the light emission brightness, as the required increase in luminous brightness, to obtain the first gate voltage applied to the full-type control electrode side.

[0067] Furthermore, in step S4, based on the first gate voltage, the first luminous efficiency improvement of the dual-gate controlled light-emitting device is obtained, including:

[0068] Substituting the first gate voltage into the relationship between first gate voltage, luminous efficiency improvement, and luminous brightness improvement, we obtain the first luminous efficiency improvement of the first gate voltage on the dual-gate controlled light-emitting device.

[0069] Furthermore, step S5 includes:

[0070] Using the actual grayscale value as the reference grayscale value, we obtain the relationship between the first gate voltage, luminous efficiency improvement, and luminous brightness improvement corresponding to the full-type control gate, and the relationship between the second gate voltage, luminous efficiency improvement, and luminous brightness reduction corresponding to the single-type control gate.

[0071] The first gate voltage and the second gate voltage are matched from the relationship between the first gate voltage, the luminous efficiency improvement, and the luminous brightness improvement, and the second gate voltage, the luminous efficiency improvement, and the luminous brightness reduction, so that the dual-gate controlled light-emitting device is affected by the first gate voltage and the second gate voltage, and the luminous efficiency is improved to be greater than the preset required luminous efficiency, and the grayscale value is improved to match the first grayscale value.

[0072] In this specific embodiment, the light-emitting functional layer includes one of a quantum dot light-emitting functional layer and an organic light-emitting functional layer.

[0073] In the first specific embodiment, the electron mobility of the light-emitting functional layer is greater than the hole mobility, the first gate control electrode is a full-type control electrode, and the second gate control electrode is a single-type control electrode.

[0074] Furthermore, the electron mobility of the light-emitting functional layer is greater than the hole mobility, making the dual-gate controlled light-emitting device electronic and... Figure 2 As shown, Figure 2 In this design, the first gate control electrode is a full-type control electrode with a positive gate voltage applied, which can improve luminous efficiency and luminous brightness. The second gate control electrode is a single-type control electrode with a positive gate voltage applied, which can improve luminous efficiency but slightly reduce luminous brightness.

[0075] In the second specific embodiment, the hole mobility of the light-emitting functional layer is greater than the electron mobility, the second gate control electrode is a full-type control electrode, and the first gate control electrode is a single-type control electrode.

[0076] Furthermore, the hole mobility in the light-emitting functional layer is greater than the electron mobility, and the dual-gate controlled light-emitting device is hole-type and... Figure 3 As shown, Figure 3 In this design, the first gate control electrode is a single-type control electrode with a negative gate voltage applied, which can improve luminous efficiency and slightly reduce luminous brightness. The second gate control electrode is a full-type control electrode with a negative gate voltage applied, which can improve both luminous efficiency and luminous brightness.

[0077] This invention first obtains the relationship between the gate voltage of the two gate control electrodes at various reference gray levels and the changes in luminous efficiency and luminous brightness. Then, based on these relationships, the first and second gate voltages for each gray level are determined. These first and second gate voltages ensure that both the luminous brightness and luminous efficiency of the dual-gate controlled light emitter meet the requirements. Compared to existing technologies, this invention considers the subtle influence of the gate controlling luminous efficiency on luminous brightness and eliminates this influence through the above method, thus improving the control accuracy.

[0078] The embodiments of the present invention adjust the luminous brightness by gate modulation, avoiding changes in the driving current. When multiple dual-gate modulated light-emitting devices are working, the driving current of the same gray level remains uniform, which facilitates driving.

[0079] In summary, the embodiments of the present invention effectively improve display quality and save energy by avoiding mutual interference between the two-end controls leading to inaccurate control, ensuring that the luminous efficiency and luminous brightness meet the requirements.
