[0022] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings, in which the same or similar components have the same or similar designations and functions throughout various figures and / or like reference numerals are used to indicate the same or like components. The embodiments described below are exemplary and are merely intended to explain the present disclosure, and are not to be understood as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications and equivalents that fall within the spirit and scope of the appended claims.

[0023] Optionally, the screen of the terminal generally includes a pixel driving circuit connected to at least one voltage, and the pixel driving circuit includes at least one thin film transistor (TFT). Optionally, the terminal can drive the TFT in the pixel driving circuit by voltage to drive the organic light-emitting diode (OLED) to emit light, so that the screen of the terminal displays images. Since the TFT characteristics drift with temperature, when the temperature decreases, the voltage difference required for the TFT to reach the saturation state also increases, which may cause the voltage of the terminal to be unable to meet the voltage difference required for the TFT to reach the saturation state, so that the TFT cannot reach the saturation state, thereby affecting the color display of the screen of the terminal. Optionally, Figure 1 is a schematic diagram of TFT characteristic drift according to an embodiment of the present disclosure, wherein, Figure 1 The first curve from top to bottom in is a schematic curve of TFT characteristic drift of a green pixel, the second curve from top to bottom is a schematic curve of TFT characteristic drift of a red pixel, and the third curve from top to bottom is a schematic curve of TFT characteristic drift of a blue pixel, as shown in Figure 1 As shown, the TFTs driving the RGB three kinds of pixels have inconsistent trends of change with temperature. The green pixel needs the largest voltage difference (i.e., EL cross voltage in the figure) at low temperature, so when the temperature decreases, the green pixel first reaches the non-saturation state, that is, the display brightness of the green pixel decreases first, which causes the screen of the terminal to appear red.

[0024] Figure 2 is a flowchart of a screen display method according to an embodiment of the present disclosure.

[0025] The embodiment takes the screen display method configured in the screen display device as an example. The screen display method in the embodiment can be configured in the screen display device, and the screen display device can be arranged in a terminal. The terminal includes at least one of a mobile phone, a wearable device, an Internet of Things device, a car with a communication function, a smart car, a tablet computer (Pad), a computer with a wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home, but is not limited thereto.

[0026] It should be noted that the execution subject of the embodiment of the present disclosure can be, for example, a central processing unit (CPU) of a terminal or a server in hardware, or a display integrated circuit (IC) chip, or a related background service of the terminal or the server in software, and is not limited thereto. The terminal in the embodiment of the present disclosure can be equipped with multiple camera devices, and each camera device can be used to capture a scene to obtain a scene image.

[0027] As shown in Figure 2 The screen display method includes the following steps.

[0028] S201: Determine a first temperature value.

[0029] In some embodiments, the first temperature value can be a current temperature value of a screen of the terminal.

[0030] In some embodiments, a temperature sensor can be arranged in the terminal, and the temperature sensor can collect the current temperature value of the screen. Optionally, the temperature sensor can collect the current temperature value once every 10 milliseconds (ms). The terminal can determine the latest collected temperature value of the temperature sensor as the first temperature value, so as to ensure the real-time and accuracy of the first temperature value.

[0031] Optionally, in some embodiments, the terminal described above can comprise a pixel driving circuit, Figure 3 is a flowchart of a pixel driving circuit according to an embodiment of the present disclosure (herein, taking Low Temperature Poly-Oxide (LTPO) 8T as an example), as shown in Figure 3 The pixel driving circuit can comprise at least one TFT (Drive TFT (DTFT) in Figure 3 ), and the pixel driving circuit can be connected to a first voltage and a second voltage, the first voltage and the second voltage being used to drive the TFT in the pixel driving circuit, that is, the first voltage and the second voltage are driving voltages of the pixel driving circuit; for example, the first voltage can be Figure 3 VSS in Figure 3 , and the second voltage can be Figure 3 VDD in

[0032] S202: In response to the first temperature value being less than the preset value, adjusting the voltage value of the first voltage to a first target voltage value based on the first temperature value, and compensating for the display of the screen.

[0033] Optionally, the preset value can be used to determine whether the terminal is currently in a low temperature, for example, the preset value can be 25°. Optionally, when the first temperature value is less than the preset value, it can be considered that the terminal is currently in a low temperature, at this time, in order to avoid the technical problem of "when the temperature decreases, the voltage of the terminal cannot meet the pressure difference required for the TFT to reach the saturation state, so that the TFT cannot reach the saturation state, thereby affecting the color display of the screen of the terminal, and the low-temperature display appears red and the low-temperature display brightness is low", it is necessary to adjust the driving voltage of the pixel driving circuit to compensate for the color cast under low-temperature display. Specifically, in some embodiments, the voltage value of the first voltage can be adjusted to a first target voltage value based on the first temperature value, so that the pressure difference between the second voltage and the first voltage can drive the TFT to be in a saturation state, thereby ensuring that the TFT can be in a saturation state even when the terminal is in a low temperature state, so that the light-emitting current of the TFT is large and constant, so that the display brightness of RGB three kinds of pixels can be large and constant, thereby ensuring that the screen of the terminal can be normally displayed under low temperature, and ensuring the stability of the color display of the screen of the terminal under low temperature.

[0034] Optionally, in some embodiments, the specific method in which the terminal adjusts the voltage value of the first voltage to a first target voltage value based on the first temperature value can comprise the following steps:

[0035] Step a, determining the first target voltage value based on a first correspondence relationship;

[0036] Optionally, the first correspondence relationship can be pre-set, and the first correspondence relationship can include: target voltage values to which the first voltage needs to be adjusted at different temperature values. Figure 4 is a schematic diagram of the first correspondence relationship proposed by an embodiment of the present disclosure, as shown in Figure 4 When the temperature value is 20°, the target voltage value to which the first voltage needs to be adjusted is -1.1V (volt), and when the temperature value is 15°, the target voltage value to which the first voltage needs to be adjusted is -1.3V.

[0037] In some embodiments, when the first target voltage value is determined based on the first correspondence relationship, the first target voltage value can be the target voltage value corresponding to the first temperature value.

[0038] In other embodiments, when the first target voltage value is determined based on the first correspondence relationship, the first target voltage value can not be the target voltage value corresponding to the first temperature value. Specifically, in some embodiments, when the terminal determines the first target voltage value in the above step a, the second temperature value can be determined based on the first temperature value first, and then the target voltage value corresponding to the second temperature value is determined as the first target voltage value. Optionally, the second temperature value can be any temperature value smaller than the first temperature value among all temperature values included in the first correspondence relationship. For example, the second temperature value can have the minimum absolute value of the difference between the first temperature value, for example, when the first temperature value is 20°, the second temperature value can be 15°, at this time, the first target voltage value can be -1.3V; or in another example, the second temperature value can be the minimum temperature value among all temperature values included in the first correspondence relationship. For example, assuming that the minimum temperature value among all temperature values included in the first correspondence relationship is -20°, and the target voltage value corresponding to -20° is -2.7V, the second temperature value can be determined as -20°, at this time, the first target voltage value can be -2.7V.

[0039] Step b, adjusting the voltage value of the first voltage to the determined first target voltage value.

[0040] It can be known from the above that, when the current temperature value of the terminal is the first temperature value, in an optional embodiment, the terminal can adjust the first voltage based on the target voltage value corresponding to the second temperature value smaller than the first temperature value, so as to pre-compensate the voltage, so as to ensure that the TFT in the pixel driving circuit can be in the saturation state in advance when the temperature decreases, and prevent the flash screen problem caused by the handshake not in time. In addition, in the embodiment of the present disclosure, the first voltage can also be adjusted directly based on the minimum temperature value in all temperature values included in the first corresponding relationship when the temperature is low, so as to realize pre-compensation and avoid the frequent adjustment of the first voltage due to the real-time change of the temperature value of the terminal. Therefore, on the basis of preventing the flash screen problem, power consumption can also be saved to the maximum extent.

[0041] It should be noted that, when low temperature compensation is performed in the low brightness interval (i.e., the above-mentioned "adjusting the voltage value of the first voltage to the first target voltage value based on the first temperature value"), the screen of the terminal is usually prone to the problem of green deviation due to the viewing angle effect, and the brightness is prone to change when the low brightness interval compensation is switched; therefore, in some embodiments, when the brightness of the screen of the terminal is less than the first brightness value, it is determined that the current is in the low brightness interval, at this time, in order to avoid the problems of green deviation, brightness change and the like, low temperature compensation can not be performed, that is, the voltage value of the first voltage is not adjusted; when the brightness of the screen of the terminal is greater than or equal to the first brightness value, it is determined that the current is in the high brightness interval, at this time, low temperature compensation is performed, that is, the voltage value of the first voltage is adjusted to the first target voltage value based on the first temperature value, so as to solve the problems of red display at low temperature, low brightness at low temperature and the like; optionally, the first brightness value can be, for example, 120 nit.

[0042] In addition, it should be noted that, in some embodiments, the screen of the terminal can further include a first area, and the terminal can collect a unlocking pattern in the first area, and unlock the terminal based on the collected unlocking pattern. Optionally, the first area can be, for example, a fingerprint light spot area of the terminal, and the unlocking pattern can be, for example, a fingerprint pattern of a user. The terminal can collect the fingerprint pattern of the user through the fingerprint light spot area, and determine whether the collected fingerprint pattern is consistent with a predetermined pattern. When the collected fingerprint pattern is consistent with the predetermined pattern, it is determined that the terminal is unlocked. Optionally, in some embodiments, since the first area has a serious redness at low temperature and a serious lack of brightness, when the terminal needs to collect the unlocking pattern through the first area (for example, when the fingerprint light spot of the terminal is on), the terminal can always perform low temperature compensation without determining whether the brightness of the first area is less than or equal to the first brightness value, thereby avoiding the problem of low temperature fingerprint unlocking success rate.

[0043] Optionally, for the always on display (AOD) mode of the terminal, since the maximum brightness thereof is currently 60 nit, the low temperature compensation can be directly turned off when the terminal is in the AOD mode.

[0044] In summary, in the present embodiment, when the current temperature value of the terminal is less than the preset value (i.e., when the terminal is currently at low temperature), the voltage value of the first voltage is adjusted, so that the pressure difference between the second voltage and the first voltage drives the TFT to be in a saturated state. That is, in the method of the present disclosure, when the terminal is at low temperature, the voltage of the terminal is adjusted to ensure that the TFT in the pixel driving circuit of the terminal is in a saturated state, so that the light emitting current of the TFT is large and constant, thereby making the display brightness of the RGB three kinds of pixels large and constant, thereby ensuring that the screen of the terminal can be normally displayed at low temperature, and ensuring the stability of the color display of the screen of the terminal at low temperature.

[0045] Figure 5 is a flow diagram of a screen display method according to another embodiment of the present disclosure.

[0046] As shown in Figure 5 , the screen display method comprises:

[0047] S501: determining a first temperature value.

[0048] S502: In response to the first temperature value being less than the preset value, adjusting a voltage value of the first voltage to a first target voltage value based on the first temperature value.

[0049] For details of steps S501-S502, please refer to the above embodiment description.

[0050] S503: When the gray scale of the screen of the terminal belongs to the second gray scale interval, adjusting a voltage value of the third voltage to a second target voltage value based on the first target voltage value.

[0051] Optionally, the gray scale of the screen of the terminal can belong to the first gray scale interval or the second gray scale interval, wherein the gray scale value of the first gray scale interval is greater than that of the second gray scale interval. For example, the first gray scale interval can be a high gray scale interval, and the second gray scale interval can be a low gray scale interval.

[0052] Optionally, the third voltage can be used to drive the TFT in the pixel driving circuit. For example, the third voltage can be Vi_ANo in the above-mentioned Figure 3 .

[0053] Optionally, the second target voltage value satisfies the following condition: the pressure difference between the third voltage and the first voltage is constant; wherein when the pressure difference between the third voltage and the first voltage is constant, the luminous current flowing through the TFT is also constant.

[0054] The following takes the first gray scale interval as the high gray scale interval and the second gray scale interval as the low gray scale interval as an example to introduce in detail the reason why "when the gray scale of the screen of the terminal belongs to the second gray scale interval, the voltage value of the third voltage is adjusted to the second target voltage value based on the first target voltage value":

[0055] Wherein, when the first voltage is adjusted at low temperature, the pressure difference required for the TFT corresponding to the low gray scale interval to reach the saturation state is usually smaller than the pressure difference required for the TFT corresponding to the high gray scale interval to reach the saturation state, that is, the TFT corresponding to the low gray scale interval reaches the saturation state first, and at this time, since the pressure difference required for the TFT corresponding to the high gray scale interval to reach the saturation state has not been reached, the first voltage needs to be adjusted to increase the pressure difference between the second voltage and the first voltage, which will cause the luminous current of the TFT in the saturation state corresponding to the low gray scale interval to increase, and since the current shunt of the green pixel is the largest, it will cause the low gray scale interval to display green, in order to solve the above-mentioned "low gray scale interval display green problem", when the gray scale of the terminal screen belongs to the second gray scale interval, the third voltage value is adjusted to the second target voltage value based on the first target voltage value, to ensure that the pressure difference between the third voltage and the first voltage is constant, and then to ensure that the luminous current flowing through the TFT is constant, thereby avoiding the technical problem of "displaying green due to the increase of the luminous current flowing through the TFT in the low gray scale interval", and ensuring the display effect and stability of the low gray scale interval.

[0056] Optionally, the method of "adjusting the voltage value of the third voltage to the second target voltage value based on the first target voltage value" can include determining the second target voltage value to which the third voltage needs to be adjusted when the first voltage is the first target voltage value based on the first correspondence relationship, and adjusting the voltage value of the third voltage to the determined second target voltage value. Optionally, as shown in Figure 4 The first correspondence relationship can also include the correspondence relationship between the first voltage and the third voltage, so the second target voltage value can be directly determined based on the first correspondence relationship and the first target voltage value determined in step S502; refer to Figure 4 When the first target voltage value is -1.1V, the second target voltage value can be -0.5V, and when the first target voltage value is -1.3V, the second target voltage value can be -0.7V.

[0057] In summary, in the embodiment, when the current temperature value of the terminal is less than the preset value (i.e. when the terminal is currently at low temperature), the voltage value of the first voltage is adjusted to make the pressure difference between the second voltage and the first voltage drive the TFT to be in the saturation state, that is, in the method of the present disclosure, when the terminal is at low temperature, the voltage of the terminal is adjusted to ensure that the TFT in the pixel driving circuit of the terminal is in the saturation state, so that the luminous current of the TFT is large and constant, so that the display brightness of the RGB three kinds of pixels is large and constant, thereby ensuring that the screen of the terminal can be normally displayed at low temperature, and ensuring the stability of color display of the screen of the terminal at low temperature.

[0058] Figure 6is a structural schematic diagram of a screen display device proposed by an embodiment of the present disclosure.

[0059] As Figure 6 shown, the screen display device 60 comprises:

[0060] A determination module is configured to determine a first temperature value, the first temperature value being a current temperature value of a screen; the screen comprises a pixel driving circuit, the pixel driving circuit comprising at least one TFT, the pixel driving circuit being connected to a first voltage and a second voltage, the first voltage and the second voltage being used to drive the TFT in the pixel driving circuit.

[0061] An adjustment module is configured to, in response to the first temperature value being less than a preset value, adjust a voltage value of the first voltage to a first target voltage value based on the first temperature value, and compensate for the display of the screen; so that a pressure difference between the second voltage and the first voltage drives the TFT to be in a saturation state.

[0062] It should be noted that the foregoing explanation and description of the screen display method also apply to the screen display device of the present embodiment, which will not be described here again.

[0063] In the present embodiment, when the current temperature value of the terminal is less than the preset value (i.e., the terminal is currently in a low temperature), the voltage value of the first voltage is adjusted so that the pressure difference between the second voltage and the first voltage drives the TFT to be in a saturation state, that is, in the method of the present disclosure, when the terminal is in a low temperature, the voltage of the terminal is adjusted to ensure that the TFT in the pixel driving circuit of the terminal is in a saturation state, so that the light-emitting current of the TFT is large and constant, thereby making the display brightness of the RGB three kinds of pixels large and constant, thereby ensuring that the screen of the terminal can be normally displayed in a low temperature, and ensuring the stability of color display of the screen of the terminal in a low temperature.
