Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 2, fig. 2 is a schematic view of an electronic device with a display screen according to an embodiment of the present invention. As shown in fig. 2, the electronic device 2 may include a display screen 21, a memory 22, a processor 23, and a power supply 24, where the display screen 21 includes a first display area 211 and a second display area 212, and a transparent layer 2111 with adjustable light transmittance is disposed on the first display area 211, where a schematic diagram of the display screen 21 may be as shown in fig. 3.
The first display region 211 is a region that is not frequently lighted, and the background color is black and cannot be adjusted, such as a status bar or a virtual key region; the second display area 212 is an area that emits light frequently and is used to display content.
In an embodiment, the display screen 21 includes a display glass 2112 and a cover glass 2113, and the transparent layer 2111 is disposed between the display glass 2112 and the cover glass 2113 at the position of the first display region 211, as shown in fig. 4 a.
In another embodiment, the display screen 21 includes a lower display glass 2114, an upper display glass 2115 and a cover glass 2116 stacked in sequence, and the transparent layer 2111 is disposed between the upper display glass 2115 and the lower display glass 2114 at the position of the first display region 211, as shown in fig. 4 b. Wherein the lower display glass 2114 includes a display circuit for displaying; the upper display glass 2115 is transparent and functions to enclose and protect the lower display glass 2114.
The memory 22 stores a set of program codes, and the processor 23 is configured to call the program codes stored in the memory 22 to perform the following operations: acquiring the historical light emitting time lengths of the first display area 211 and the second display area 212; and adjusting the light transmittance of the transparent layer 2111 according to the historical light emitting time of the first display area 211 and the second display area 212.
When the display screen 21 is switched from the off-screen state to the on-screen state, the processor 23 may acquire the historical light emitting periods of the first display area 211 and the second display area 212. The historical light emitting time periods of the first display area 211 and the second display area 212 refer to the light emitting time periods of the first display area 211 and the second display area 212 recorded by the processor 23 before the current screen-on. The historical light-emitting time length is recorded from the first time of screen lightening after the electronic device leaves a factory.
Optionally, the transparent layer 2111 is made of a material whose luminance varies with current, the electronic device 2 may further include a variable resistor (omitted in fig. 2), the variable resistor is connected between the power supply 24 and the transparent layer 2111, the power supply 24 provides a fixed voltage, and the processor 23 controls a resistance value of the variable resistor to change a magnitude of current provided by the power supply 24 to the transparent layer 2111, so as to change a light transmittance of the transparent layer 2111.
Further optionally, the adjusting, by the processor 23, the light transmittance of the transparent layer 2111 according to the historical light emitting time of the first display area 211 and the second display area 212 includes: determining a color difference between the first display region 211 and the second display region 212 according to the historical light emitting time lengths of the first display region 211 and the second display region 212; and adjusting the light transmittance of the transparent layer 2111 according to the determined color difference.
The manner of determining the color difference between the first display region 211 and the second display region 212 by the processor 23 according to the historical light emitting time lengths of the first display region 211 and the second display region 212 may include the following two manners:
in a first mode, the processor 23 may calculate the attenuation degree of the first display region 211 and the second display region 212, respectively, and determine the color difference between the first display region and the second display region according to the attenuation degree of the first display region and the second display region. In a specific implementation, the processor 23 may determine a first attenuation degree of the first display region 211 according to the historical light emitting time length of the first display region 211 and the attenuation speed of the light emitting material of the display screen, determine a second attenuation degree of the second display region 212 according to the historical light emitting time length of the second display region 212 and the attenuation speed of the light emitting material of the display screen, and determine an absolute difference between the first attenuation degree and the second attenuation degree as the color difference. Since the longer the light emitting time of the OLED display screen is, the greater the material loss of the OLED display screen is, the accuracy of the color difference between the first display region 211 and the second display region 212 determined according to the historical light emitting time of the first display region and the second display region is higher.
In the second mode, since the first display region 211 has a short light emission time, the attenuation of the first display region 211 may be ignored, and only the attenuation degree of the second display region 212 may be calculated. In a specific implementation, the processor 23 may determine a second attenuation degree of the second display area 212 according to the historical light emitting time of the second display area 212 and the attenuation speed of the light emitting material of the display screen, and determine the second attenuation degree of the second display area 212 as the color difference.
Further, the processor 23 may also detect whether the historical light emitting time of the first display region 211 reaches a preset time threshold, and if so, it indicates that the light emitting material of the first display region 211 has a certain loss, calculate the color difference of the display screen in a first manner; otherwise, it is stated that the loss of the luminescent material in the first display area 212 is small and can be ignored, and the color difference of the display screen is calculated in the second way. The preset time threshold may be an empirical value, and is used as a standard for judging whether the luminescent material of the display screen is lost, and may be set before leaving a factory or set by a user.
The adjusting, by the processor 23, the light transmittance of the transparent layer 2111 according to the determined color difference may specifically be: according to the formula
And determining the expected light transmittance required to be achieved by the transparent layer 2111, and adjusting the light transmittance of the transparent layer 2111 to the expected light transmittance according to the above, wherein Y is the light transmittance, W is the gray order of the chromatic aberration, and T is the total order of the transparent effect. The memory 22 stores a correspondence between a color difference and a gray scale number of the color difference in advance, and the processor 23 determines the gray scale number of the current color difference according to the correspondence between the color difference stored in the memory 22 and the gray scale number of the color difference after determining the color difference between the first display region 211 and the second display region 212.
The total number of the transparent effects is preset, and can be 256, 512, 1024, etc., taking 256 as an example, that is, the opacity from full transparency of the white picture to 75% (or other preset values, such as 50%, 60%, etc.) is divided into 256 levels of 0-255, and each level corresponds to one transparent effect. If W is equal to 0, Y is equal to 100%, which indicates that there is no color difference between the first display area 211 and the second display area 212, and at this time, the display of the first display area 211 does not need to be interfered, and the transparent layer is completely transparent; assuming that W is equal to 255 and Y is equal to 0%, indicating that the color difference between the first display region 211 and the second display region 212 is severe, the transparent layer has the least transparent effect in 256 steps (i.e., the opaque effect of 75% of white image can be superimposed on the black background to balance the color). W is between 0 and 255 and so on. The embodiment of the invention is different from the prior art in that: according to the invention, the transparent layer for compensating the chromatic aberration is added in the area with the chromatic aberration, so that the consistency of the display effect of the whole display screen is ensured.
Further, after the display screen 21 is switched to the screen-on state, the processor 23 starts to record the light-emitting durations of the first display area 211 and the second display area 212 during the period from the screen-on to the screen-on end, and updates the historical light-emitting duration correspondingly according to the fact that the recorded light-emitting duration is accumulated to the stored historical light-emitting duration. Assuming that the historical light emitting time lengths of the first display area 211 and the second display area 212 are respectively 12.1h and 500h, and the current light emitting time lengths of the first display area 211 and the second display area 212 recorded by the processor 23 are respectively 0.1h and 1.5h, the updated historical light emitting time lengths of the first display area 211 and the second display area 212 are respectively 12.2h and 501.5 h.
In the embodiment shown in fig. 2, the display screen 21 includes a first display area 211 and a second display area 212, a transparent layer 2111 with an adjustable light transmittance is disposed on the first display area 211, and by adjusting the light transmittance of the transparent layer 2111, the color difference between the first display area 211 and the second display area 212 of the display screen is reduced, thereby improving the display effect.
Referring to fig. 5, fig. 5 is a flowchart illustrating a method for adjusting a display effect of a display screen according to an embodiment of the present invention. The method as shown in fig. 5 may include:
in step S51, the processor acquires the history light emission time periods of the first display region and the second display region.
When the display screen is switched from the screen-off state to the screen-on state, the processor may obtain the historical light emitting durations of the first display area and the second display area of the display screen. The historical light-emitting time lengths of the first display area and the second display area refer to the light-emitting time lengths of the first display area and the second display area recorded by the processor before the current screen lightening. The historical light-emitting time length is recorded from the first time of screen lightening after the electronic device leaves a factory.
And step S52, the processor adjusts the light transmittance of the transparent layer arranged on the first display area according to the historical light emitting duration of the first display area and the second display area.
Referring to fig. 6, fig. 6 is a sub-flowchart of step S52. Specifically, the step S52 includes:
in step S521, the processor determines whether the light emitting duration of the first display area is less than a preset duration threshold. If the light emitting duration of the first display area is less than the preset duration threshold, which indicates that the loss of the light emitting material of the first display area is small and can be ignored, then step S524 is executed; otherwise, it indicates that there is a certain loss in the luminescent material of the first display region, step S522 is executed.
It should be noted that, in other alternative embodiments, after acquiring the historical light emitting time lengths of the first display area and the second display area, the processor may directly perform step S522, or directly perform step S524.
In step S522, the processor calculates the attenuation levels of the first display region and the second display region, respectively.
The decay rates of different luminescent materials are different, while the decay degree of the same luminescent material is related to the historical luminescence time, and the longer the historical luminescence time is, the more the decay is. The memory may pre-store a correspondence of the light emission duration to the degree of attenuation, the correspondence being related to the luminescent material of the display screen.
In a specific implementation, the processor may determine a first attenuation degree of the first display area according to the historical light emitting duration of the first display area and the attenuation speed of the light emitting material of the display screen, and determine a second attenuation degree of the second display area according to the historical light emitting duration of the second display area and the attenuation speed of the light emitting material of the display screen.
In step S523, the processor determines the absolute difference between the attenuation degrees of the first and second display regions as the color difference between the first and second display regions.
In step S524, the processor calculates the degree of attenuation of the second display region.
In step S525, the processor determines the attenuation degree of the second display region as the color difference between the first and second display regions.
In step S526, the processor adjusts the light transmittance of the transparent layer according to the color difference determined in step S523 or step S525.
In particular, the processor may be based on a formula
And determining the light transmittance of the transparent layer, and adjusting the transparent layer according to the light transmittance, wherein Y is the light transmittance, W is the gray order of the chromatic aberration, and T is the total order of the transparent effect.
The total number of the transparent effects is preset, and can be 256, 512, 1024, etc., taking 256 as an example, that is, the opacity from full transparency of the white picture to 75% (or other preset values, such as 50%, 60%, etc.) is divided into 256 levels of 0-255, and each level corresponds to one transparent effect. If W is equal to 0, Y is equal to 100%, which indicates that there is no color difference between the first display area and the second display area, and at this time, the display of the first display area does not need to be interfered, and the transparent layer is completely transparent; assuming that W is equal to 255 and Y is equal to 0%, indicating that the color difference between the first display area and the second display area is severe, the transparent layer is completely opaque (i.e. the opaque effect of 75% of the white image can be superimposed on the black background to balance the color). W is between 0 and 255 and so on. The embodiment of the invention is different from the prior art in that: according to the invention, the transparent layer for compensating the chromatic aberration is added in the area with the chromatic aberration, so that the consistency of the display effect of the whole display screen is ensured.
Further, after the display screen is switched to the screen-on state, the processor starts to record the light-emitting duration of the first display area and the second display area from the screen-on state to the screen-on end, and updates the historical light-emitting duration according to the recorded light-emitting duration. Assuming that the historical light emitting time lengths of the first display area and the second display area are respectively 12.1h and 500h, and the light emitting time lengths of the first display area and the second display area recorded by the processor at this time are respectively 0.1h and 1.5h, the updated historical light emitting time lengths of the first display area and the second display area are respectively 12.2h and 501.5 h.
In the embodiments shown in fig. 5 and 6, the processor obtains the historical light emitting durations of the first display area and the second display area, and adjusts the light transmittance of the transparent layer disposed on the first display area according to the historical light emitting durations of the first display area and the second display area, so as to reduce the color difference between the first display area and the second display area, thereby improving the display effect.
