[0049] It should be noted that the technical features in the different embodiments described below may be replaced, reorganized or mixed with each other to constitute another embodiment without departing from the spirit of the present disclosure.

[0050] Please also refer to Figure 1 as well as Figure 2 , Figure 1 is a schematic diagram of an electronic device according to a first embodiment of the present disclosure. Figure 2 1 is a flow chart of a driving method according to an embodiment of the present disclosure. In the present embodiment, the electronic device 100 includes a sensor 110, a controller 120, a driving circuit 130, and electronic units EU1 and EU2. The driving method S100 is applicable to the electronic device 100. The driving method S100 includes steps S110 to S130. In step S110, the sensor 110 senses the ambient temperature to generate ambient temperature information. For example, the sensor 110 senses the first ambient temperature AT1 to generate the first ambient temperature information IAT1. The sensor 110 senses the second ambient temperature AT2 to generate the second ambient temperature information IAT2.

[0051] In this embodiment, the controller 120 is electrically connected to the sensor 110. The controller 120 receives the ambient temperature information (such as one of the first ambient temperature information IAT1 and the second ambient temperature information IAT2) provided by the sensor 110 in step S120. The driving circuit 130 is electrically connected to the controller 120. The driving circuit 130 generates different driving signals according to different ambient temperature information in step S130. The driving circuit 130 drives the electronic units EU1 and EU2 according to the driving signals in step S130. For example, the driving signal is a signal generated according to the data corresponding to the memory 140, and the data includes gamma data. The driving circuit 130 drives the electronic units EU1 and EU2 according to different ambient temperature information using different driving signals. For example, when the ambient temperature is substantially equal to the first ambient temperature AT1, the driving circuit 130 generates the first driving signal SDR1 according to the first ambient temperature information IAT1. The first driving signal SDR1 corresponds to the first ambient temperature AT1. The driving circuit 130 drives the electronic units EU1 and EU2 using the first driving signal SDR1.

[0052] For another example, when the ambient temperature is substantially equal to the second ambient temperature AT2, the driving circuit 130 generates a second driving signal SDR2 according to the second ambient temperature information IAT2. The second driving signal SDR2 corresponds to the second ambient temperature AT2. The driving circuit 130 uses the second driving signal SDR2 to drive the electronic units EU1 and EU2.

[0053] The driving signals SDR1 and SDR2 respectively include at least one driving voltage signal, at least one driving current signal or at least one pulse-width modulation (PWM) signal, but are not limited thereto.

[0054] The electronic units EU1 and EU2 have a first operating state at the first ambient temperature AT1 based on the first drive signal SDR1 (e.g., display brightness at the first ambient temperature AT1). The electronic units EU1 and EU2 have a second operating state at the second ambient temperature AT2 based on the second drive signal SDR2 (e.g., display brightness at the second ambient temperature AT2). Based on the correction drive method of this embodiment, the electronic units EU1 and EU2 have the same operating state under the change of ambient temperature.

[0055] In this embodiment, the electronic units EU1 and EU2 are, for example, voltage-driven components, but the disclosure is not limited thereto. The electronic units EU1 and EU2 can provide corresponding operations based on the voltage value of the first driving signal SDR1 at the first ambient temperature AT1. The electronic units EU1 and EU2 can provide corresponding operations based on the voltage value of the second driving signal SDR2 at the second ambient temperature AT2.

[0056] It is worth mentioning here that the driving circuit 130 drives the electronic units EU1 and EU2 according to the driving signals corresponding to different ambient temperatures. In this way, the driving circuit 130 and the electronic units EU1 and EU2 operate stably or maintain the same operating performance under the change of ambient temperature. For example, it can avoid the situation where the current rises due to the increase of ambient temperature, so that the electronic device activates the overcurrent protection device and causes the electronic device to be abnormal. In addition, when the electronic device is, for example, a display device, and the electronic units EU1 and EU2 are, for example, light-emitting elements, in the same screen and when the ambient temperature becomes higher, the electronic units EU1 and EU2 can maintain the same luminous brightness, and the dark state screen can be maintained in the dark state when the ambient temperature becomes higher, and the screen will not be brighter due to the increase in temperature, providing the viewer with a good viewing experience.

[0057] In the present embodiment, the driving circuit 130 generates a driving signal according to a driving command corresponding to the ambient temperature information in step S130, but the present disclosure is not limited to the present embodiment. In the present embodiment, the electronic device 100 also includes a memory 140. The memory 140 stores data of different driving signals corresponding to different ambient temperature information. Taking the present embodiment as an example, the memory 140 is connected to the driving circuit 130. The controller 120 provides a corresponding driving command according to the received ambient temperature information. The driving circuit 130 selects data corresponding to the driving command from the memory 140 according to the received driving command, and generates a driving signal according to the data.

[0058] For example, the controller 120 provides the driving command CMD1 according to the first ambient temperature information IAT1. The driving circuit 130 selects the first data DT1 corresponding to the driving command CMD1 from the memory 140 according to the driving command CMD1, and generates the driving signal SDR1 according to the first data DT1.

[0059] For another example, the controller 120 provides the driving command CMD2 according to the second ambient temperature information IAT2. The driving circuit 130 selects the second data DT2 corresponding to the driving command CMD1 from the memory 140 according to the driving command CMD2, and generates the driving signal SDR2 according to the second data DT2.

[0060] After step S130 , the electronic device 100 may return to the operation of step S110 .

[0061] This embodiment exemplifies the electronic units EU1 and EU2. However, the present disclosure is not limited to this embodiment, and the electronic unit disclosed in the present disclosure may be one or more.

[0062] In the present embodiment, the electronic units EU1 and EU2 may respectively include, for example, at least one of a diode, a capacitor, a resistor, a transistor or a pixel unit in any form. The diode may include a light emitting diode or a photodiode. The light emitting diode may include, for example, an organic light emitting diode (OLED), a sub-millimeter light emitting diode (mini LED), a micro light emitting diode (micro LED) or a quantum dot light emitting diode (quantum dot LED, which may include QLED, QDLED), or other suitable materials, or a combination thereof, but is not limited thereto.

[0063] In this embodiment, the electronic units EU1 and EU2 can be disposed outside or inside the electronic device 100. The combination of the electronic device 100 and the electronic units EU1 and EU2 can be a light source device, a backlight module, a display or a modulation device.

[0064] In this embodiment, the sensor 110 may be disposed outside the electronic device 100 to sense the external environment temperature of the electronic device 100. The sensor 110 may be disposed inside the electronic device 100 to sense the internal environment temperature of the electronic device 100.

[0065] In the present embodiment, the electronic unit EU1 can provide output light CL1 (but the present disclosure is not limited thereto). The electronic unit EU2 can provide output light CL2 (but the present disclosure is not limited thereto). Taking the present embodiment as an example, the color of the output light CL1 is different from the color of the output light CL2. The first data DT1 includes gamma data DG1 and DG2. The gamma data DG1 and DG2 respectively have data of different gamma curves. The gamma data DG1 corresponds to the electronic unit EU1. The gamma data DG2 corresponds to the electronic unit EU2. In addition, the second data DT2 includes gamma data DG3 and DG4. The gamma data DG3 and DG4 respectively have data of different gamma curves. The gamma data DG3 corresponds to the electronic unit EU1. The gamma data DG4 corresponds to the electronic unit EU2. For example, when the ambient temperature is substantially equal to the first ambient temperature AT1, the driving circuit 130 generates the first driving signal SDR1 to drive the electronic unit EU1 and the electronic unit EU2 according to the gamma data DG1 and the gamma data DG2, respectively. When the ambient temperature is substantially equal to the second ambient temperature AT2, the driving circuit 130 generates the second driving signal SDR2 to drive the electronic unit EU1 and the electronic unit EU2 according to the gamma data DG3 and the gamma data DG4, respectively. In some embodiments, the color of the output light CL1 of the electronic unit EU1 is the same as the color of the output light CL2 of the electronic unit EU2 (for example, both are blue, white, or other suitable colors), so the driving circuit 130 can generate the same driving signal to drive the electronic units EU1 and EU2 according to the same gamma data.

[0066] In this embodiment, the sensor 110 may include a thermistor. The thermistor has a negative temperature coefficient (NTC) or a positive temperature coefficient (PTC). The sensor 110 may provide ambient temperature information, such as one of the first ambient temperature information IAT1 and the second ambient temperature information IAT2, according to the resistance value of the thermistor.

[0067] In this embodiment, the controller 120 is, for example, a microcontroller unit (MCU), a central processing unit (CPU), or other programmable general-purpose or special-purpose microprocessors, digital signal processors (DSP), programmable controllers, application specific integrated circuits (ASIC), programmable logic devices (PLD), or other similar devices or combinations of these devices.

[0068] In this embodiment, the memory 140 may be any type of fixed or removable random access memory (RAM), read-only memory (ROM), flash memory or similar elements or a combination of the above elements.

[0069] Please also refer to Figure 1 as well as Figure 3 , Figure 3 It is a flow chart of a driving method shown in an embodiment of the present disclosure. In this embodiment, the driving method S200 is applicable to the controller 120 of the electronic device 100. The driving method S200 includes steps S210 to S240. In step S210, the controller 120 loads multiple sets of data into the memory 140. Taking this embodiment as an example, the controller 120 at least loads the first data DT1 and the second data DT2 into the memory 140. In step S220, the controller 120 receives ambient temperature information. In step S230, the controller 120 determines whether the ambient temperature has changed. When the ambient temperature changes, the controller 120 controls the driving circuit 130 to change the driving signal in step S240. On the other hand, when the ambient temperature has not changed, the controller 120 returns to the operation in step S220.

[0070] Taking this embodiment as an example, during the first period, the controller 120 receives the first ambient temperature information IAT1. During the second period after the first period, the controller 120 receives the second ambient temperature information IAT2. In step S230, the controller 120 determines that the ambient temperature has changed from the first ambient temperature AT1 to the second ambient temperature AT2 based on the change in the ambient temperature information. In step S240, the controller 120 changes the drive command CMD1 to the drive command CMD2. Therefore, the drive circuit 130 changes the first drive signal SDR1 to the second drive signal SDR2 based on the drive command CMD2. The drive circuit 230 drives the electronic units EU1 and EU2 using the second drive signal SDR2.

[0071] On the other hand, during the second period, the controller 120 receives the first ambient temperature information IAT1. The controller 120 determines in step S230 that the ambient temperature is maintained at the first ambient temperature AT1. Therefore, the controller 120 does not change the drive command CMD1. The drive circuit 130 drives the electronic units EU1 and EU2 using the first drive signal SDR1.

[0072] Please refer to Figure 4 , Figure 4 2 is a schematic diagram of an electronic device according to a second embodiment of the present disclosure. In this embodiment, the electronic device 200 includes a sensor 210, a controller 220, a driving circuit 230, a memory 240, and a functional circuit 250. The sensor 210 senses a first ambient temperature AT1 to generate a first ambient temperature information IAT1. The sensor 210 senses a second ambient temperature AT2 to generate a second ambient temperature information IAT2. The controller 220 is electrically connected to the sensor 210. The controller 220 receives one of the first ambient temperature information IAT1 and the second ambient temperature information IAT2. The functional circuit 250 is electrically connected to the controller 220 and the driving circuit 230. The functional circuit 240 is electrically connected to the controller 220, the driving circuit 230, and the memory 240.

[0073] The controller 220 provides a driving command according to the received ambient temperature information. The functional circuit 250 selects at least one set of data from the memory 240 according to the received driving command. The data selected by the functional circuit 250 corresponds to the driving command provided by the controller 220. The driving circuit 230 generates a driving signal according to the data selected by the functional circuit 250.

[0074] For example, the controller 220 provides the driving command CMD1 according to the first ambient temperature information IAT1. The function circuit 250 selects the first data DT1 from the memory 240 according to the driving command CMD1. The function circuit 250 provides the first data DT1 to the driving circuit 230. The driving circuit 230 generates the driving signal SDR1 according to the first data DT1.

[0075] For another example, the controller 220 provides the driving command CMD2 according to the second ambient temperature information IAT2. The function circuit 250 selects the second data DT2 from the memory 240 according to the driving command CMD2. The function circuit 250 provides the second data DT2 to the driving circuit 230. The driving circuit 230 generates the driving signal SDR2 according to the second data DT2.

[0076] In this embodiment, the functional circuit 250 may be implemented by an application specific integrated circuit (ASIC), but the present disclosure is not limited thereto.

[0077] In this embodiment, the driving method S100 may also be applicable to the electronic device 200 .

[0078] Please refer to Figure 4 as well as Figure 5 , Figure 5 It is a flow chart of a driving method shown in an embodiment of the present disclosure. In this embodiment, the driving method S300 is applicable to the electronic device 200. The driving method S300 includes steps S310 to S350. In step S310, the controller 220 loads multiple sets of data into the memory 240. Taking this embodiment as an example, the controller 220 at least loads the first data DT1 and the second data DT2 into the memory 240. In step S320, the controller 220 receives ambient temperature information. In step S330, the controller 220 determines whether the ambient temperature changes. When the ambient temperature changes, the controller 220 controls the functional circuit 250 to select different data in step S340. Therefore, the driving circuit 230 changes the driving signal according to different data in step S350.

[0079] On the other hand, in step S330 , when the ambient temperature has not changed, the controller 220 returns to the operation in step S320 .

[0080] Taking this embodiment as an example, in the first period, the controller 220 receives the first ambient temperature information IAT1. In the second period after the first period, the controller 220 receives the second ambient temperature information IAT2. In step S330, the controller 220 determines that the ambient temperature has changed from the first ambient temperature AT1 to the second ambient temperature AT2 based on the change of the ambient temperature information. In step S340, the controller 220 changes the drive command CMD1 to the drive command CMD2. The functional circuit 250 selects the second data DT2 from the memory 240. Therefore, the drive circuit 230 changes the first drive signal SDR1 to the second drive signal SDR2 based on the second data DT2 in step S350. The drive circuit 230 drives the electronic units EU1 and EU2 using the second drive signal SDR2.

[0081] On the other hand, during the second period, the controller 220 receives the first ambient temperature information IAT1. The controller 220 determines in step S330 that the ambient temperature is maintained at the first ambient temperature AT1. The controller 220 does not change the drive command CMD1. Therefore, the drive circuit 230 drives the electronic units EU1 and EU2 using the first drive signal SDR1.

[0082] Please also refer to Figure 1 , Figure 4 , Figure 6 as well as Figure 7 , Figure 6 is a schematic diagram of data shown according to an embodiment of the present disclosure. Figure 7 : is a schematic diagram of generating data according to an embodiment of the present disclosure. In this embodiment, the electronic unit EU1 is, for example, a light-emitting element. New data other than the first data DT1 and the second data DT2 can be generated. The first drive signal SDR1 is generated based on the first data DT1. The first drive signal SDR1 corresponds to the first data DT1. The second drive signal SDR2 is generated based on the second data DT2. The second drive signal SDR2 corresponds to the second data DT2. The first data DT1 and the second data DT2 respectively include gamma data (e.g., gamma data DG1~DG4). The first ambient temperature AT1 corresponds to the first ambient temperature information IAT1. The first ambient temperature information IAT1 corresponds to the first data DT1. The second ambient temperature AT2 corresponds to the second ambient temperature information IAT2. The second ambient temperature information IAT2 corresponds to the second data DT2.

[0083] The brightness performance of the electronic unit EU1 based on the first driving signal SDR1 is shown in the characteristic curve CV1. The characteristic curve CV1 corresponds to the first ambient temperature AT1. The characteristic curve CV1 has a larger brightness increase. The brightness performance of the electronic unit EU1 based on the second driving signal SDR2 is shown in the characteristic curve CV2. The characteristic curve CV2 corresponds to the second ambient temperature AT2. The characteristic curve CV2 has a smaller brightness increase. Under different ambient temperatures, the brightness of the electronic unit EU1 is positively correlated with the value of the first driving signal SDR1 and the value of the second driving signal SDR2. The value may be a voltage value, a current value or a duty cycle, but is not limited thereto. For example, the first ambient temperature AT1 is lower than the second ambient temperature AT2. Generally speaking, the brightness generated by the electronic unit EU1 at the first ambient temperature AT1 is lower than the brightness generated at the second ambient temperature AT2. Therefore, when the electronic unit EU1 is at the first ambient temperature AT1, the electronic unit EU1 corrects the poor condition of low brightness based on the first driving signal SDR1. When the electronic unit EU1 is at the second ambient temperature AT2, the electronic unit EU1 corrects the unfavorable condition of high brightness based on the second driving signal SDR2. Therefore, the operating performance of the electronic unit EU1 can be maintained at different ambient temperatures.

[0084] In some embodiments, different electronic units EU1 have different operating states due to different designs or characteristics. For example, the first ambient temperature AT1 is lower than the second ambient temperature AT2. The operating state of the electronic unit EU1 at the first ambient temperature AT1 is better than the operating state at the second ambient temperature AT2. Therefore, the characteristic curve CV1 has a smaller operating state increment. The characteristic curve CV2 has a larger operating state increment. Therefore, the electronic unit EU1 can have the same operating state and maintain the same operating performance under different ambient temperatures through the correction drive method.

[0085] In this embodiment, the third ambient temperature AT3 is between the first ambient temperature AT1 and the second ambient temperature AT2. Therefore, the electronic device 100 performs an interpolation operation on the first data DT1, the second data DT2, and the third ambient temperature AT3 to generate the third data DT3. The third data DT3 corresponds to the third ambient temperature AT3. Further, the electronic device 100 uses the computing unit CU to add the third data DT3. For example, the computing unit CU can add the third data DT3 according to formula (1).

[0086]

[0087] In formula (1), the operation unit CU subtracts the value of the second ambient temperature AT2 from the value of the first ambient temperature AT1 to generate a first difference (i.e., "AT1-AT2"). The operation unit CU subtracts the value of the second ambient temperature AT2 from the value of the third ambient temperature AT3 to generate a second difference (i.e., "AT3-AT2"). The operation unit CU divides the second difference by the first difference to generate a proportional value. The operation unit CU subtracts the second data DT2 from the first data DT1 to generate a data difference (i.e., "DT1-DT2"), and multiplies the data difference by the proportional value to generate a product value. Next, the operation unit CU adds the product value to the second data DT2 to generate the third data DT3.

[0088] In some embodiments, the controller 120 receives the third ambient temperature information IAT3 corresponding to the third ambient temperature AT3. Therefore, the electronic device 100 can interpolate the first data DT1, the second data DT2 and the third ambient temperature information IAT3 to generate the third data DT3. The third data DT3 corresponds to the third ambient temperature information IAT3.

[0089] In this embodiment, the third data DT3 may not be stored in the memory 140. The third data DT3 may be transmitted to the driving circuit 130. The driving circuit 130 generates the driving signal SDR3 according to the third data DT3.

[0090] In some embodiments, the third data DT3 is loaded into the memory 140. Afterwards, the controller 120 may provide a corresponding driving command according to the third ambient temperature information IAT3. The driving circuit 130 selects the third data DT3 from the memory 140 according to the driving command, and generates a corresponding third driving signal SDR3 according to the third data DT3. Therefore, the brightness generated by the electronic unit EU1 based on the third driving signal is shown as the characteristic curve CV3. The brightness change of the characteristic curve CV3 is greater than the brightness change of the characteristic curve CV2 and less than the brightness change of the characteristic curve CV1.

[0091] In some embodiments, the fourth data newly added by performing the interpolation operation is loaded into the memory 140 and covers the original third data DT3.

[0092] In this embodiment, the operation unit CU may be disposed in the controller 120 or the driving circuit 130. The operation unit CU may also be disposed outside the controller 120 and the driving circuit 130.

[0093] It should be understood that the third data DT3 generation method of this embodiment is applicable to the electronic device 200. In the electronic device 200, the operation unit CU can be set in the controller 220, the driving circuit 230 or the functional circuit 250. The operation unit CU can also be set outside the controller 220, the driving circuit 230 and the functional circuit 250.

[0094] In summary, the driving circuit of the electronic device drives the electronic unit according to the driving signal corresponding to different ambient temperatures. In this way, the driving circuit and the electronic unit operate stably or maintain the same operating performance under the change of ambient temperature. In addition, the driving circuit generates a corresponding driving signal according to data. The electronic device can generate new driving signals with different data and newly added driving signals corresponding to new data.
