This state will cause the display screen to be unable to display content normally during the boot period (e.g., the display screen may be black or distorted), resulting in a poor user experience.

[0003] In view of this, how to provide a display technology that can solve the problem that the display system cannot display normally when it is turned on in a low temperature environment is a goal that the industry urgently needs to work hard on. Summary of the Invention

The embedded controller is electrically connected to the thermal sensor and the light-emitting device. The thermal sensor is used to sense ambient temperature information of the light-emitting device. In response to receiving a power-on signal, the embedded controller receives the ambient temperature information from the thermal sensor to determine whether the ambient temperature information is lower than a temperature threshold. In response to the ambient temperature information being lower than the temperature threshold, the embedded controller determines a first light-emitting control signal, wherein the first light-emitting control signal includes a luminance and a light-emitting time. The light-emitting device receives the first light-emitting control signal so that the light-emitting device performs a light-emitting operation corresponding to the first light-emitting control signal.

[0010] In one embodiment of the present invention, the display system further performs the following operation: in response to the switching control signal indicating the normal mode, the switching circuit transmits a second light-emitting control signal to the light-emitting device so that the light-emitting device performs the light-emitting operation corresponding to a preset brightness.

[0011] In one embodiment of the present invention, the embedded controller determines the luminance and the light-emitting time based on a display panel size corresponding to the light-emitting device.

[0031] The following will explain a display system and method provided by the present disclosure through implementation methods. However, these implementation methods are not intended to limit the present disclosure to any environment, application or method as described in these implementation methods. Therefore, the description of the implementation methods is only for the purpose of illustrating the present disclosure, and is not intended to limit the scope of the present disclosure. It should be understood that in the following implementation methods and drawings, elements that are not directly related to the present disclosure have been omitted and are not shown, and the sizes of each element and the size ratios between elements are only for illustration, and are not intended to limit the scope of the present disclosure.

[0032] In this embodiment, if Figure 1 As shown, the display system DS includes a light emitting device 11, a thermal sensor 13, and an embedded controller 15. In this embodiment, the thermal sensor 13 is used to sense the ambient temperature information of the light emitting device 11.

[0033] In some embodiments, the thermal sensor 13 may be disposed within the display system DS, on the display system DS housing, in the surrounding area of ​​the light-emitting device 11, or in the environment via an external connection (e.g., a communication connection). In some embodiments, the thermal sensor 13 may transmit ambient temperature information to the embedded controller 15 via a communication connection.

[0034] It should be noted that the light-emitting device 11 can be a light-emitting element of a display screen known to those skilled in the art (e.g., a backlight module light bar). The thermal sensor 13 can be any sensor capable of detecting temperature. The embedded controller 15 can be various processing units, microprocessors, or other computing devices known to those skilled in the art.

[0035] In this embodiment, in response to receiving a power-on signal (eg, received by the embedded controller 15 ), the display system DS receives the ambient temperature information from the thermal sensor 13 to determine whether the ambient temperature information is lower than a temperature threshold.

[0036] In some embodiments, the temperature threshold can be dynamically adjusted. Specifically, the display system DS can dynamically adjust the temperature threshold during implementation based on the normal operating temperatures of different driver integrated circuits. For example, for certain type A driver integrated circuits, the corresponding temperature threshold can be set to -20 degrees Celsius. For certain type B driver integrated circuits, the corresponding temperature threshold can be set to -25 degrees Celsius.

[0037] In this embodiment, in response to the ambient temperature information being lower than the temperature threshold, the embedded controller 15 of the display system DS determines a first light control signal, wherein the first light control signal includes a luminance and a light time.

[0038] In some embodiments, the embedded controller 15 determines the luminance and the luminous time based on a display panel size corresponding to the light-emitting device 11 .

[0039] For example, the corresponding relationship between the display panel size, the luminance, and the luminous time can be set as shown in Table 1 below. When the display panel size is less than 11 inches, the corresponding luminance is 60% and the luminous time is 2 minutes. When the display panel size is between 11 inches and 13 inches, the corresponding luminance is 80% and the luminous time is 2 minutes. When the display panel size is between 13 inches and 15 inches, the corresponding luminance is 100% and the luminous time is 2 minutes. When the display panel size is greater than 15 inches, the corresponding luminance is 100% and the luminous time is 3 minutes.

[0040]

[0041] Table 1

[0042] In this embodiment, the light emitting device 11 receives the first light emitting control signal so that the light emitting device 11 performs a light emitting operation corresponding to the first light emitting control signal. For example, the first light emitting control signal can be transmitted to the light emitting device 11 by the embedded controller 15 in the display system DS.

[0043] For example, when the display panel size is smaller than 11 inches, the lighting device 11 receives the first lighting control information corresponding to a luminance of 60% and a lighting time of 2 minutes. The lighting device 11 then performs a lighting operation at a luminance of 60% for 2 minutes.

[0044] For another example, when the display panel size is between 13 inches and 15 inches, the light-emitting device 11 receives the first light-emitting control information corresponding to a luminance of 100% and a light-emitting time of 2 minutes, and the light-emitting device 11 performs a light-emitting operation with a luminance of 100% maintained for 2 minutes.

[0045] In some embodiments, the first light control signal may also include multiple luminance levels and multiple light-emitting times, so that the light-emitting device 11 can dynamically adjust the luminance level and light-emitting time of the light-emitting device 11. For example, the light-emitting device 11 may emit light at a luminance of 100% for the first minute and at a luminance of 80% for the next minute.

[0046] It should be noted that if the temperature of the display system DS components (e.g., the driver power supply) has not yet reached the operating temperature before the power-on operation is performed, it may cause display abnormalities (e.g., the display system DS may have a black screen or a distorted screen), resulting in a poor user experience.

[0047] In some embodiments, to avoid the aforementioned situation, the display system DS performs the system login operation only after confirming that the lighting operation is complete (i.e., the preheating operation is complete). Specifically, the embedded controller 15 determines whether the lighting device 11 has completed the lighting operation corresponding to the first lighting control signal. Then, in response to the lighting device 11 completing the lighting operation corresponding to the first lighting control signal, the embedded controller 15 instructs an operating system to perform a system login operation.

[0048] In some embodiments, the light emitting device 11 can heat a driver integrated circuit on an integrated circuit board through the light emitting element. It should be noted that the driver integrated circuit can be an integrated circuit that controls and provides power to the light emitting element.

[0049] For easier understanding, please refer to Figure 2 A schematic diagram of the light emitting device 11 shown in FIG. Figure 2 As shown, the light-emitting device 11 further includes a light-emitting element 111 and an integrated circuit board 113. The integrated circuit board 113 is electrically connected to the light-emitting element 111. Specifically, the integrated circuit board 113 receives the first light-emitting control signal and controls the light-emitting element 111 to perform the light-emitting operation corresponding to the luminosity and the light-emitting time based on the first light-emitting control signal, thereby heating a driver integrated circuit on the integrated circuit board 113.

[0050] In some embodiments, the light emitting element 111 is disposed in a peripheral area of ​​the driver integrated circuit. For example, the light emitting element 111 can be disposed in a strip, L-shaped, ring-shaped, or other shape in the peripheral area of ​​the driver integrated circuit.

[0051] In some embodiments, the display system DS further includes a switching circuit and a central processing unit. The switching circuit is used to switch between different execution modes, such as a heating mode in which the light-emitting device performs a heating operation, a normal mode in which the central processing unit performs a power-on operation, a heating mode in which the central processing unit performs an overclocking operation, and the like.

[0052] For easier understanding, please refer to Figure 3 The display system DS diagram is shown in FIG. Figure 3 As shown, the display system DS further includes a central processing unit 35 and a switching circuit 33 . The switching circuit 33 is electrically connected to the central processing unit 35 , the embedded controller 15 and the light emitting device 11 .

[0053] In some embodiments, the switching circuit 33 receives a switching control signal from the embedded controller 15, wherein the switching control signal indicates a heating mode or a normal mode. Then, in response to the switching control signal indicating the heating mode, the switching circuit 33 transmits the first light-emitting control signal to the light-emitting device 11, causing the light-emitting device 11 to perform the light-emitting operation corresponding to the first light-emitting control signal.

[0054] In some embodiments, the embedded controller 15 is electrically connected to the central processing unit 35, and in response to the switching control signal indicating the heating mode, the embedded controller 15 transmits an overclocking control signal to the central processing unit 35 so that the central processing unit 35 performs an overclocking operation corresponding to the overclocking control signal (for example, increasing the processor frequency), wherein the control signal includes an overclocking setting.

[0055] For example, the embedded controller 15 can transmit an overclocking control signal from the Platform Environment Control Interface (PECI) to enable the CPU 35 to perform operations with Turbo Boost, and the overclocking setting can correspond to overclocking environment setting parameters of different overclocking levels (for example, the clock frequency, current, temperature, power, and number of operating cores of the CPU 35).

[0056] It should be noted that since the CPU 35 generates a large amount of heat when performing the overclocking operation, it can heat the temperature of components of the display system DS (eg, the driving power supply), so that the display system DS quickly reaches an operating temperature capable of performing the boot operation.

[0057] It should be understood that the present disclosure does not limit the number of operations performed simultaneously in the heating mode. The display system DS can simultaneously perform overclocking operations through the central processor 35 and perform lighting operations through the lighting device 11, so that the display system DS quickly reaches the operating temperature capable of performing the power-on operation.

[0058] In some embodiments, the display system DS may also allocate heating mode operations according to different ratios (eg, execution time) or priorities (eg, temperature thresholds).

[0059] For example, the display system DS can be configured to have a 2:1 ratio between the time it spends performing the lighting operation and the time it spends performing the overclocking operation. For another example, the display system DS can be configured to only perform the lighting operation when the temperature is between -20°C and -30°C. Furthermore, the display system DS can be configured to simultaneously perform the overclocking operation and the lighting operation when the temperature is below -30°C.

[0060] In some embodiments, when the display system DS is at a normal operating temperature, the switching circuit 33 may transmit a lighting control signal to the lighting device 11, causing the lighting device 11 to perform a lighting operation at a preset brightness. Specifically, in response to the switching control signal indicating the normal mode, the switching circuit 33 transmits a preset control signal to the lighting device 11, causing the lighting device 11 to perform the lighting operation corresponding to the preset brightness.

[0061] As can be seen from the above description, the display system DS provided by the present disclosure can actively sense ambient temperature information. When the display system DS receives a power-on signal and the ambient temperature is too low, the display system DS actively generates heat using a variety of different combinations to quickly reach the operating temperature. Because the display system DS provided by the present disclosure can resolve the problem of the display system not displaying properly when powered on in a low-temperature environment, it overcomes the shortcomings of the prior art that can result in a poor user experience.

The thermal sensor is used to sense the ambient temperature of the light-emitting device. The display method 400 causes the light-emitting device to perform a light-emitting operation through steps S401 to S405.

[0063] First, in step S401 , in response to receiving a power-on signal, the embedded controller receives the ambient temperature information from the thermal sensor to determine whether the ambient temperature information is lower than a temperature threshold.

[0064] Next, in step S403 , in response to the ambient temperature information being lower than the temperature threshold, the embedded controller determines a first light-emitting control signal, wherein the first light-emitting control signal includes a luminance and a light-emitting time.

[0065] Finally, in step S405 , the light emitting device receives the first light emitting control signal, so that the light emitting device performs a light emitting operation corresponding to the first light emitting control signal.

[0066] In some embodiments, the display method 400 further includes the following steps: the embedded controller determines whether the light-emitting device has completed the light-emitting operation corresponding to the first light-emitting control signal; and in response to the light-emitting device completing the light-emitting operation corresponding to the first light-emitting control signal, the embedded controller instructs an operating system to perform a system login operation.

[0067] In some embodiments, the display method 400 further includes the following steps: until the light-emitting device completes the light-emitting operation, a preheating completion signal is generated to instruct an operating system to perform a system login operation.

[0068] In some embodiments, the light-emitting device further includes a light-emitting element and an integrated circuit board, the integrated circuit board is electrically connected to the light-emitting element, and the display method 400 further includes the following steps: receiving the first light-emitting control signal by the integrated circuit board; and controlling the light-emitting element to perform the light-emitting operation corresponding to the luminosity and the light-emitting time based on the first light-emitting control signal by the integrated circuit board to heat a driving integrated circuit on the integrated circuit board.

[0069] In some embodiments, the light emitting element is disposed in a peripheral area of ​​the driver integrated circuit.

[0070] In some embodiments, the display system further includes a central processing unit and a switching circuit, which is electrically connected to the central processing unit, the embedded controller and the light-emitting device, and the display method 400 further includes the following steps: the switching circuit receives a switching control signal from the embedded controller, wherein the switching control signal is used to indicate a heating mode or a normal mode; and in response to the switching control signal indicating the heating mode, the switching circuit transmits the first light-emitting control signal to the light-emitting device so that the light-emitting device performs the light-emitting operation corresponding to the first light-emitting control signal.

[0071] In some embodiments, the embedded controller is electrically connected to the central processing unit, and the display method 400 further includes the following steps: in response to the switching control signal indicating the heating mode, the embedded controller transmits an overclocking control signal to the central processing unit so that the central processing unit performs an overclocking operation corresponding to the overclocking control signal, wherein the control signal includes an overclocking setting.

[0072] In some embodiments, the display method 400 further includes the following steps: in response to the switching control signal indicating the normal mode, the switching circuit transmits a preset control signal to the light-emitting device to enable the light-emitting device to perform the light-emitting operation corresponding to a preset brightness.

[0073] In some embodiments, the luminance and the luminous duration are determined based on a display panel size corresponding to the light-emitting device.

[0074] In addition to the above steps, the second embodiment can also perform all operations and steps of the display system DS described in the first embodiment, having the same functions and achieving the same technical effects. Those skilled in the art of the present disclosure will readily understand how the second embodiment performs these operations and steps based on the first embodiment, having the same functions and achieving the same technical effects, and therefore, a detailed description thereof will not be given.

[0075] It should be noted that in the patent specification and claims of this invention, certain terms (including light control signals, etc.) are preceded by "first" or "second." Such "first" or "second" is used solely to distinguish different terms. For example, the "first" and "second" in the first light control signal and the second light control signal are used solely to indicate different light control signals used in different operations.

[0076] In summary, the display technology provided by this disclosure (including at least the system and method) can actively sense ambient temperature information. When the display system receives a power-on signal and the ambient temperature is too low, it can actively generate heat based on a variety of different combinations to quickly reach the operating temperature of the device.
