[0002] OLED (Organic Light-Emitting Diode) display technology is hailed as a new technology to replace LCD and is currently the technological direction for most panel display industries.

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

[0028] See Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the driving circuit provided in this application. The driving circuit 100 includes a driving transistor T0, a light-emitting module 10, a storage module 20, and a driving module 30.

[0029] The storage module 20 includes a storage capacitor C (not shown). The storage module 20 is configured to input a reference voltage VREF to the drain, gate, and first terminal of the storage capacitor C of the driving transistor T0, and to connect the source of the driving transistor T0 and the second terminal of the storage capacitor C. The driving module 30 is configured to input a data signal DATA to the second terminal of the storage capacitor C, input a first driving voltage ELVDD to the drain of the driving transistor T0, connect the gate of the driving transistor T0 and the first terminal of the storage capacitor C, and connect the source of the driving transistor T0 and the light-emitting module 10.

[0030] Specifically, the driving transistor T0 is a TFT, and the threshold voltage Vth of the TFT is the minimum voltage at which the TFT starts to work or produces an observable effect when the voltage applied to the TFT control electrode (usually the gate) exceeds a certain threshold.

[0031] Specifically, the storage capacitor C in the driving circuit 100 is mainly used to store voltage data, and can also transmit voltage differences. The storage capacitor C can latch the data storage node. When data is written, the storage capacitor C captures and saves these charges to maintain the data state until the next write or reset operation. In one embodiment, the storage capacitor C can extract the threshold voltage Vth of the storage TFT, eliminating the influence of the threshold voltage Vth on the light-emitting module 10.

[0032] Specifically, the first driving voltage ELVDD (ELeVated VDD) represents the forward driving voltage, which provides the necessary voltage for the light-emitting module 10 to emit light normally, and its voltage value is usually fixed. When the driving transistor T0 is in the on state, the first driving voltage ELVDD is input to the light-emitting module 10 through the driving transistor T0, and the light-emitting module 10 is driven to emit light. By adjusting the magnitude of the first driving voltage ELVDD, the current intensity flowing through the light-emitting module 10 can be controlled. The larger the first driving voltage ELVDD, the larger the current flowing through the light-emitting module 10 will generally be. The magnitude of the current directly affects the brightness of the light-emitting module 10. Under the same conditions, the larger the current, the brighter the light emitted by the light-emitting module 10; conversely, the smaller the current, the lower the brightness.

[0033] Specifically, the data signal DATA is the key to achieving high-quality image display on display devices. By precisely controlling the light emission state and color intensity of each pixel, the data signal DATA ensures that the display device can present clear, delicate, and colorful image effects.

[0034] One technical solution adopted in this application is to provide a driving circuit, which includes: a driving transistor; a light-emitting module; a storage module including a storage capacitor, the storage module being configured to input a reference voltage to the drain and gate of the driving transistor and a first terminal of the storage capacitor, and to connect the source of the driving transistor and a second terminal of the storage capacitor; and a driving module being configured to input a data signal to the second terminal of the storage capacitor, input a first driving voltage to the drain of the driving transistor, connect the gate of the driving transistor and the first terminal of the storage capacitor, and connect the source of the driving transistor and the light-emitting module. Through the above method, the influence of the TFT threshold voltage on the OLED display can be eliminated, improving the display quality.

[0035] See Figure 2 , Figure 2 This is a schematic diagram of the structure of the second embodiment of the driving circuit provided in this application. The driving circuit 100 includes a driving transistor T0, a light-emitting module 10, a storage module 20, and a driving module 30.

[0036] The storage module 20 includes a storage capacitor C. The storage module 20 is configured to input a reference voltage VREF to the drain, gate, and first terminal of the storage capacitor C of the driving transistor T0, and to connect the source of the driving transistor T0 and the second terminal of the storage capacitor C. The driving module 30 is configured to input a data signal DATA to the second terminal of the storage capacitor C, input a first driving voltage ELVDD to the drain of the driving transistor T0, connect the gate of the driving transistor T0 and the first terminal of the storage capacitor C, and connect the source of the driving transistor T0 and the light-emitting module 10.

[0037] Optionally, the storage module 20 includes a first switch T1 and a second switch T2. The first switch T1 is configured to receive an input reference voltage VREF, and its second terminal is connected to the drain of the driving transistor T0. The first terminal of the second switch T2 is connected to the drain of the driving transistor T0, and its second terminal is connected to the gate of the driving transistor T0. The first switch T1 and the second switch T2 are configured to be turned on during the reset phase and turned off during the write phase.

[0038] Optionally, the storage module 20 further includes a third switch T3 and a fourth switch T4. The first terminal of the third switch T3 is connected to the first terminal of the storage capacitor C, and the second terminal of the third switch T3 is configured to be the input reference voltage VREF; the first terminal of the fourth switch T4 is connected to the source of the driving transistor T0, and the second terminal of the fourth switch T4 is connected to the second terminal of the storage capacitor C; wherein, the third switch T3 and the fourth switch T4 are configured to be turned on during the reset phase and turned off during the write phase.

[0039] Specifically, during the reset phase, the first switch T1 and the second switch T2 are in the on state, and the reference voltage signal VREF is input to the drain and gate of the driving transistor T0. At this time, the gate and drain of the driving transistor T0 are shorted together. The driving transistor T0 can be regarded as a diode. The voltage at point N1 (equivalent to the anode voltage of the diode) is the reference voltage VREF, and the voltage at point N2 (equivalent to the cathode voltage of the diode) is VREF-Vth, where Vth represents the threshold voltage of the driving transistor T0.

[0040] Next, during the reset phase, the third switch T3 and the fourth switch T4 are in the ON state. At this time, the reference voltage is input to the first terminal of the storage capacitor C through the third switch T3, and the source of the driving transistor T0 is connected to the second terminal of the storage capacitor C through the fourth switch T4, making the voltage at the second terminal of the storage capacitor C the same as the voltage at point N2. At this time, the voltage at the first terminal of the storage capacitor C is the reference voltage VREF, and the voltage at the second terminal is VREF-Vth. The voltage difference across the storage capacitor C is:

[0041] VREF-(VREF-Vth)=VREF-VREF+Vth

[0042] =Vth

[0043] Understandably, the threshold voltage Vth of the driving transistor T0 is stored in the storage capacitor C.

[0044] See Figure 3 , Figure 3 This is a schematic diagram of the structure of the third embodiment of the driving circuit provided in this application. The driving circuit 100 includes a driving transistor T0, a light-emitting module 10, a storage module 20, and a driving module 30.

[0045] The storage module 20 includes a storage capacitor C. The storage module 20 is configured to input a reference voltage VREF to the drain, gate, and first terminal of the storage capacitor C of the driving transistor T0, and to connect the source of the driving transistor T0 and the second terminal of the storage capacitor C. The driving module 30 is configured to input a data signal DATA to the second terminal of the storage capacitor C, input a first driving voltage ELVDD to the drain of the driving transistor T0, connect the gate of the driving transistor T0 and the first terminal of the storage capacitor C, and connect the source of the driving transistor T0 and the light-emitting module 10.

[0046] Figure 3 The driving circuit 100 shown is Figure 2 The main difference in the driving circuit 100 shown is the addition of descriptions of the components added to the light-emitting module 10 and the driving module 30. Therefore, the following mainly describes the added components to the light-emitting module 10 and the driving module 30. For other components in the driving circuit 100, please refer to [link to relevant documentation]. Figure 2The related descriptions of the illustrated embodiments, for example Figure 3 The storage module 20 in the middle can be seen in Figure 2 The description of storage module 20 will not be repeated here.

[0047] Optionally, the light-emitting module 10 includes: a light-emitting diode D, specifically an organic light-emitting diode, the anode of the light-emitting diode D being connected to the second terminal of the eighth switching transistor T8 of the driving transistor, and the cathode of the light-emitting diode D being configured to receive the second driving voltage ELVSS (ELeVated VSS).

[0048] Specifically, corresponding to the first driving voltage ELVDD, the second driving voltage ELVSS represents the negative driving voltage, which is an adjustable voltage used to provide a negative voltage to the light-emitting diode D. By adjusting the voltage of the first driving voltage ELVDD, fine control of the brightness of the light-emitting diode D can be achieved; the lower the voltage of the first driving voltage ELVDD, the lower the brightness of the light-emitting diode D.

[0049] Optionally, the driving module 30 includes a first driving unit 31, a second driving unit 32, and a third driving unit 33. The first driving unit 31 is configured to input a data signal DATA to the second terminal of the storage capacitor C and to connect the gate of the driving transistor T0 and the first terminal of the storage capacitor C; the second driving unit 32 is configured to input a first driving voltage ELVDD to the drain of the driving transistor T0; and the third driving unit 33 is configured to connect the source of the driving transistor T0 and the light-emitting module 10.

[0050] Optionally, the first driving unit 31 includes a fifth switch T5 and a sixth switch T6. The first terminal of the fifth switch T5 is configured to input a data signal DATA, and the second terminal of the fifth switch T5 is connected to the second terminal of the storage capacitor C; the first terminal of the sixth switch T6 is connected to the first terminal of the storage capacitor C, and the second terminal of the sixth switch T6 is connected to the gate of the driving transistor T0; wherein, the fifth switch T5 and the sixth switch T6 are configured to be off during the reset phase and on during the write phase.

[0051] Optionally, the second driving unit 32 includes a seventh switch T7, the first terminal of which is configured to receive a first driving voltage ELVDD, and the second terminal of which is connected to the drain of the driving transistor T0; wherein the seventh switch T7 is configured to be cut off during the reset phase and turned on during the light emission phase.

[0052] Optionally, the third driving unit 33 includes an eighth switch T8, the first end of which is connected to the source of the driving transistor T0, and the second end of which is connected to the light-emitting module 10; wherein the eighth switch T8 is configured to be cut off during the reset phase and turned on during the light-emitting phase.

[0053] Specifically, during the write phase, the fifth switch T5 and the sixth switch T6 are in the ON state. The data signal DATA is input to the second terminal of the storage capacitor C through the fifth switch T5, and the second terminal of the storage capacitor C is connected to the gate of the driving transistor T0 through the sixth switch T6. Because the storage capacitor C has already stored the threshold voltage Vth of the driving transistor T0 during the reset phase, the voltage of the storage capacitor C will not change abruptly. Therefore, the voltage at point N1 becomes VDATA + Vth, that is, the gate voltage of the driving transistor T0 is also VDATA + Vth, where VDATA represents the voltage value of the data signal DATA.

[0054] Next, during the light-emitting stage, the seventh switch T7 and the eighth switch T8 are in the ON state. The first driving voltage ELVDD is input to the drain of the driving transistor T0 through the seventh switch T7 and the eighth switch T8, and the LED D starts to emit light. At this time, the current I flowing through the LED D is:

[0055] I=k[ELVDD-(VDATA+Vth-Vth-VD-ELVSS]^2

[0056] =k[ELVDD-(VDATA-VD-ELVSS)]^2

[0057] Where k represents the conversion factor of the driving transistor T0, and VD represents the voltage drop of the light-emitting diode D.

[0058] Understandably, the driving transistor T0 controls the current flowing through the LED D based on its gate voltage and threshold voltage Vth. As mentioned above, the gate voltage of the driving transistor T0 becomes VDATA + Vth during the writing phase. k is related to the physical parameters of the driving transistor T0, while VD depends on the current flowing through the LED D and the characteristics of the LED D. The current I is proportional to the square of ELVDD - (VDATA + Vth - Vth - VD - ELVSS), which is derived from the saturation current formula of the TFT and will not be described in detail here. In this way, the influence of the TFT threshold voltage Vth on the current flowing through the LED D is eliminated, thereby eliminating the influence of the threshold voltage Vth on the OLED display and solving the problem of uneven OLED display caused by the offset of the threshold voltage Vth.

[0059] See Figure 4 , Figure 4 This is a schematic diagram of the fourth embodiment of the driving circuit provided in this application.

[0060] Specifically, in one embodiment, the first switch T1, the second switch T2, the third switch T3, the fourth switch T4, the fifth switch T5, the sixth switch T6, the seventh switch T7, and the eighth switch T8 are all TFT transistors. Their operating state is controlled by the gate (i.e., control terminal) voltage signal of the TFT transistor. When the gate voltage signal is high, the TFT transistor is in the on state; when the gate voltage signal is low, the TFT transistor is in the off state.

[0061] Specifically, during the reset phase, the first switch T1, the second switch T2, the third switch T3, and the fourth switch T4 are turned on, while the fifth switch T5, the sixth switch T6, the seventh switch T7, and the eighth switch T8 are turned off; during the write phase, the first switch T1, the second switch T2, the third switch T3, the fourth switch T4, the seventh switch T7, and the eighth switch T8 are turned off, while the fifth switch T5 and the sixth switch T6 are turned on; during the light emission phase, the first switch T1, the second switch T2, the third switch T3, the fifth switch T5, and the sixth switch T6 are turned off, while the fourth switch T4, the seventh switch T7, and the eighth switch T8 are turned on.

[0062] Figure 4 The diagram shows the timing of the gate voltages of each switch transistor. G1, G2, G3, G4, G5, G6, G7 and G8 represent the gate voltages of the first switch transistor T1, the second switch transistor T2, the third switch transistor T3, the fourth switch transistor T4, the fifth switch transistor T5, the sixth switch transistor T6, the seventh switch transistor T7 and the eighth switch transistor T8, respectively. Figure 4 The timing sequence divides a frame into three sub-frames, corresponding to three stages of circuit driving: reset stage, write stage, and light emission stage. This driving process compensates for the offset of the threshold voltage Vth of the driving transistor T0, thereby improving image quality and enhancing the stability of the OLED display screen.
