[0069] The following will be combined with the accompanying drawings to clearly and completely describe the embodiments of this application. Obviously, the described embodiments are only embodiments of one area of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0070] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0071] As described in the background technology section, how to ensure the display effect while protecting the user's eyes to a certain extent has become an important issue of concern to those skilled in the art.

[0072] Based on the above, the present application provides an electronic device, such as Figure 1 As shown, Figure 1 This is a structural diagram of a display panel provided in this application. The electronic device includes: a display screen 100 and a backlight module 200.

[0073] The backlight module 200 includes a first light source 202 and a second light source 204. The first light source 202 is a full-spectrum light source, and the second light source 204 emits a light beam of at least one color. At least part of the color gamut range of the first light beam emitted by the first light source 202 is located within the color gamut range of the second light beam emitted by the second light source 204. That is, the color gamut range of the first light beam can be partially located within the color gamut range of the second light beam, or can be entirely located within the color gamut range of the second light beam. It should be noted that if a part of the color gamut range of the first light beam is located within the color gamut range of the second light beam, a part of the color gamut range of the second light beam can overlap a part of the color gamut range of the first light beam, or the color gamut range of the second light beam can be located within the color gamut range of the first light beam. It should be noted that the first light source 202 is a full-spectrum light source, that is, the first light source 202 can be a white light full-spectrum light source.

[0074] At least one of the first light source 202 and the second light source 204 emits a light beam to form a display light beam. The display screen 100 can realize a target display based at least on the display light beam.

[0075] In which, the color gamut range of the display beam includes at least one of the color gamut range of the first beam and the color gamut range of the second beam. Specifically, the first light source 202 emits a beam to form a display beam, and the color gamut range of the display beam includes the color gamut range of the first beam; the second light source 204 emits a beam to form a display beam, and the color gamut range of the display beam includes the color gamut range of the second beam; the first light source 202 and the second light source 204 emit beams to form a display beam, and the color gamut range of the display beam includes the color gamut range of the first beam and the second beam.

[0076] In addition, if the display light beam includes a second light beam, the color gamut range of the display light beam changes as the color gamut range of the second light beam changes. That is, when the display light beam includes the second light beam, and when the display light beam includes the first light beam and the second light beam, the color gamut range of the display light beam changes as the color gamut range of the second light beam changes. It should be noted that since the first light beam is a full-spectrum light beam emitted by a full-spectrum white light LED, its color gamut range is determined. Since at least part of the color gamut range of the first light beam is within the color gamut range of the second light beam, the color gamut range of the second light beam may overlap with the color gamut range of the first light beam, or the color gamut range of the second light beam may include the color gamut range of the first light beam, thereby allowing the color gamut range of the second light beam to include a portion outside the color gamut range of the first light beam. Furthermore, when the display light beam includes the first light beam and the second light beam, its color gamut range may change due to changes in the color gamut range of the second light beam.

[0077] It should also be noted that the second light beam emitted by the second light source 204 can be at least one of the three primary colors of red, green, and blue. That is, the second light source 204 can be an RGB three-in-one LED light source capable of emitting red, green, and blue light beams. Specifically, the second light source 204 can simultaneously emit light beams of the three colors of red, green, and blue, or any one of these colors, or any two of these colors simultaneously. That is, the second light beam can be a light beam including the three colors of red, green, and blue, or any two of the three primary colors of red, green, and blue, or any one of the three colors of red, green, and blue. Based on this, when the display light beam includes the second light beam, its color gamut range will change due to the increase or decrease of different color light beams in the second light beam. Therefore, when the display light beam includes the second light beam, its color gamut range will also change with the change of the color gamut range of the second light beam.

[0078] It is known that the color gamut range of the second light beam can include portions outside the color gamut range of the first light beam, that is, the color gamut range of the second light beam can include portions outside the color gamut range of the first light beam. The second light beam includes a light beam of at least one color, that is, the color range of the second light beam is variable. Therefore, when the display light beam includes the first light beam and the second light beam, the color gamut range of the display light beam can change as the color gamut range of the second light beam changes. Specifically, the color gamut range of the display light beam can change as the color gamut range of the second light beam changes outside the color gamut range of the first light beam. For example, if the color gamut of the portion of the second light beam outside the color gamut range of the first light beam decreases, the color gamut range of the display light beam decreases. For another example, if the color gamut of the portion of the second light beam outside the color gamut range of the first light beam increases, the color gamut range of the display light beam increases. In other words, the color gamut range of the second light beam and changes in its color gamut range can change the color gamut range of the display light beam, that is, the color gamut range of the display light beam can change as the color gamut range of the second light beam changes.

[0079] When the electronic device performs display, if the color gamut range required by the display light beam is within the color gamut range of the first light beam, the first light beam can be used to achieve display, that is, the first light beam can be used to achieve target display.

[0080] However, when the color gamut range required by the target display exceeds the color gamut range of the first light beam, the first light beam cannot meet the color gamut requirements of the target display, and the target display cannot be achieved. It is known that the color gamut range of the second light beam can include portions outside the color gamut range of the first light beam and can change the color gamut range of the display light beam. Therefore, when the color gamut range required by the target display exceeds the color gamut range of the first light beam, the second light beam can be added to the display light beam to compensate for the color gamut range of the first light beam, thereby expanding the color gamut range of the display light beam, meeting the color gamut requirements of the target display, and displaying the target display.

[0081] In summary, when the electronic device performs display, it can display using full-spectrum white light or by combining full-spectrum white light with at least one of the three primary colors of red, green, and blue. When display is achieved through the combination of full-spectrum white light and at least one of the three primary colors of red, green, and blue, that is, when the display light beam includes a first light beam and a second light beam, the color gamut of the display light beam can vary with the color gamut of the second light beam. In other words, when the electronic device performs display, it can perform display based on the full-spectrum light beam or based on the combination of the full-spectrum light beam and the second light beam. That is, the electronic device can adjust the color gamut of the display light beam based on the full-spectrum light beam according to the color gamut requirements of the target display, thereby achieving a display function based on the full-spectrum light beam with an adjustable color gamut. Because the full-spectrum light beam can better protect the user's eyes, the electronic device achieves a display function based on the full-spectrum light beam with an adjustable color gamut through the first light source 202 and the second light source 204. This allows the electronic device to be applicable to a variety of application scenarios with different color gamut requirements. While being applicable to a variety of application scenarios with different color gamut requirements, it also takes into account the user's vision health and has advantages such as a simple structure. It should be noted that when the display screen 100 performs high color gamut display, that is, when the color gamut range of the target display is required to be higher, the color gamut range of the target display can be automatically switched to by the operating system or manually switched.

[0082] Furthermore, it is known that when the electronic device performs a display, the display light beam can be formed by the second light beam emitted by the second light source 204, that is, the electronic device can also display using the three primary colors of red, green, and blue. In other words, when the electronic device performs a display, it can display using full-spectrum white light, or it can display using the combination of full-spectrum white light and at least one of the three primary colors of red, green, and blue, or it can display using the three primary colors of red, green, and blue. In other words, the electronic device has multiple display modes, can adapt to various application scenarios, and has strong practicality.

[0083] It should be noted that when the color gamut range of the first light beam cannot meet the color gamut requirements of the target display, the target display is usually a high-purity color gamut application scenario such as picture display, video playback, and game interface display. Usually, such application scenarios have a large color gamut range and bright colors. When the color gamut range of the first light beam meets the color gamut requirements of the target display, that is, when the color gamut range of the target display is within the color gamut range of the first light beam, the target display can usually be used for most office interface displays, as well as low-color gamut application scenarios such as the operating system interface display of electronic devices. Figure 2 As shown, Figure 2 It can be a schematic diagram of the color gamut range of the first light beam and the second light beam, Figure 2RGB represents the color gamut range of the first light beam, R'G'B' represents the color gamut range of the second light beam, and R''G''B'' can represent the color gamut range of the target display. Figure 2 It can be seen that the part of the color gamut range of the second light beam that exceeds the color gamut range of the first light beam has higher color purity and is more vivid. Therefore, when the target display is a high-purity color gamut application scenario such as picture display, video playback, and game interface display, the second light beam can be added to the display beam to adjust the color gamut range of the display beam to meet the high-purity color gamut requirements of the target display.

[0084] In one embodiment of the present application, Figure 1 As shown, the backlight module 200 further includes a light guide structure 206. The light guide structure 206 is located on the non-display side of the display screen 100. The backlight module 200 responds to the display instruction and forms a display light beam. That is, the backlight module 200 responds to the display instruction and controls at least one of the first light source 202 and the second light source therein to emit a light beam to form a display light beam. The display screen 100 can achieve a target display based on the display light beam.

[0085] In another embodiment of the present application, Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of an electronic device provided in the present application. The backlight module 200 further includes a light guide structure 206. The light guide structure 206 is located on the display side of the display screen 100. The backlight module 200 responds to display instructions and controls at least one of the first light source 202 and the second light source therein to emit a light beam to form a display beam. The display screen 100 can achieve a target display based on the display beam and the ambient light beam in the environment in which the electronic device is located.

[0086] Based on the above, it can be seen that the light guide structure 206 and the first light source 202 and the second light source 204 of the electronic device can be located on either the non-display side or the display side of the display screen 100. In other words, the backlight module of the electronic device can be located on either the display side or the non-display side, and can be flexibly adjusted according to the application scenario, which is highly practical.

[0087] It should be noted that the above Figure 1 and Figure 3 The first light source 202 and the second light source 204 are respectively located on two opposite sides of the light guide structure 206 for illustration, but this application does not limit this and will be described in detail in the subsequent content.

[0088] Regarding the design method of arranging the first light source 202 and the second light source 204 on the light guide structure 206, no matter the backlight module 200 is located on the non-display side or the display side of the display screen 100, the design method of arranging the first light source 202 and the second light source 204 on the light guide structure 206 can adopt the same design concept. For example, in one embodiment of the present application, Figure 1 and Figure 4 As shown, Figure 4 for Figure 1 In the top view of the backlight module of the electronic device shown, the first light source 202 and the second light source 204 are respectively located on either side of the light guide structure 206 along a first direction, wherein the first direction is parallel to the plane of the backlight module 200. In other words, the first light source 202 and the second light source 204 can be respectively located on opposite sides of the light guide structure 206. Since the display screen of the electronic device is usually rectangular, and the light guide structure 206 is also rectangular, the first light source 202 and the second light source 204 can be arranged on two opposite short sides of the light guide structure 206 to save the number of LED lamp beads used in the first and second light sources and reduce costs. Alternatively, the first light source 202 and the second light source 204 can also be arranged on two opposite long sides of the light guide structure 206 to obtain higher display brightness.

[0089] In another embodiment of the present application, Figure 5 and Figure 6 As shown, Figure 5 This is a schematic diagram of the structure of an electronic device provided in this application. Figure 6 for Figure 5 In the top view of the backlight module in the electronic device shown, the first light source 202 and the second light source 204 are located on either side of the light guide structure 206 along a first direction, and the first light source 202 and the second light source 204 are arranged along a second direction. The first direction is parallel to the plane of the backlight module 200, and the second direction is perpendicular to the plane of the backlight module 200. In other words, the first light source 202 and the second light source 204 can also be located on the same side of the light guide structure 206 and arranged in an overlapping manner. Similar to the above embodiment, the first light source 202 and the second light source 204 can be located on both the short side and the long side of the light guide structure 206. Unlike the above embodiment, the first light source 202 and the second light source 204 are arranged on the same side of the light guide structure 206 in a stacked manner, occupying less space, which allows the backlight module 200 to have more space for arranging or designing other components and realizing more functions. When the first light source 202 and the second light source 204 are located on the same side of the light guide structure 206, they can be located on the short side of the light guide structure 206 (eg Figure 6 ), or may be located on the long side of the light guide structure 206 (as shown in FIG. Figure 7shown).

[0090] Based on the above, it should be understood that the first light source 202 and the second light source 204 may be located on two adjacent sides in addition to being located on the same side or on two opposite sides, and the specific arrangement may be flexible based on needs.

[0091] It should be noted that, whether the first light source 202 and the second light source 204 are located on opposite sides of the light guide structure 206, on the same side, or on adjacent sides, the first light source 202 and the second light source 204 can partially cover the side on which they are located to save the number of LED lamp beads used and reduce costs, or they can completely cover the side on which they are located to achieve higher display brightness. Among them, for the coverage degree of the first light source 202 and the second light source 204, taking the first light source 202 and the second light source 204 being located on opposite sides of the light guide structure 206 as an example, it can be the coverage degree in the direction parallel to the plane where the light guide structure 206 is located (such as Figure 8 ), or it may be the coverage in a direction perpendicular to the plane where the light guide structure 206 is located (as shown in FIG. Figure 9 As shown). The coverage of the first light source 202 and the second light source 204 on the sides where they are located may be the same or different.

[0092] It should also be noted that the above embodiments are described as two independent light source chips, that is, the first light source 202 and the second light source 204 are respectively implemented by different light source chips. However, this application is not limited to this. The first light source 202 and the second light source 204 can also be integrated into the same light source chip, that is, one light source chip can act as the first light source 202 to emit the first light beam, can also act as the second light source 204 to emit the second light beam, or can act as the first light source 202 and the second light source 204 to emit light beams at the same time. Preferably, the first light source 202 and the second light source 204 are two independent light source chips, that is, the first light source 202 and the second light source 204 are respectively integrated into different light source chips, so that the positions and quantities of the first light source 202 and the second light source 204 can be set separately based on actual needs. Among them, when the first light source 202 and the second light source 204 are integrated into the same light source chip, the first light source 202 and the second light source 204 can be arranged only on one side of the light guide structure 206, or can be arranged on multiple sides of the light guide structure 206. When the first light source 202 and the second light source 204 are arranged on multiple sides of the light guide structure 206 , the arrangement on the light guide structure 206 may refer to the arrangement when the first light source 202 and the second light source 204 are respectively integrated into two independent light source chips, which will not be repeated here.

[0093] In addition, regardless of whether the first light source 202 and the second light source 204 are respectively integrated into two independent light source chips or integrated into the same light source chip, the light source chips can be arranged on the light guide structure 206 in the form of LED light strips, and are usually rectangular LED light strips. However, this application does not limit the relative sizes of the LED light strips on different sides of the light guide structure 206. The sizes of the first light source 202 and the second light source 204 can be the same or different.

[0094] It should also be noted that the above embodiment describes the backlight module 200 as an edge-type backlight module, but this application is not limited to this. The backlight module 200 can also be a direct-type backlight module, that is, the first light source 202 and the second light source 204 are located on the side of the backlight module 200 away from the display screen 100, that is, the first light source 202 and the second light source 204 are located directly below the display screen 100, that is, on the side where the driver chip is located in the display module of the electronic device. The display module of an electronic device generally includes a display screen, a backlight module, a driver chip, and other display-related components, which will not be described in detail here.

[0095] For the backlight module 200 located on the display side of the display screen 100, that is, for an electronic device with a reflective display, the electronic device also includes a photosensitive module (not shown in the figure), which is located on the display side of the display screen 100 and in the non-display area of the display screen 100. The photosensitive module should be located at the same position as, or close to, the pixel structure of the reflector in the display screen 100. The photosensitive module may include a photosensitive structure and a filter structure disposed on the photosensitive structure. The photosensitive structure is used to obtain the color gamut range of the ambient light beam, and the filter structure is used to obtain the light intensity of the ambient light beam. The photosensitive structure in the photosensitive module may be a cerium-doped photosensitive structure to achieve a better photosensitivity effect.

[0096] The photosensitive module obtains the color gamut range of the ambient light beam. Based on the color gamut range of the ambient light beam and the color gamut range of the target display, the backlight module 200 responds to the display instruction and forms a display light beam, so that the display screen 100 can achieve the target display based on the display light beam and the ambient light beam in the environment where the electronic device is located.

[0097] It can be seen from this that the electronic device can be an electronic device that can utilize reflective display of ambient light beams, thereby reducing the demand for the first light beam and the second light beam during the display process, and further reducing the power consumption of the first light source 202 and the second light source 204, so that the energy consumption of the electronic device is reduced and energy is saved.

[0098] It should be noted that for the above-mentioned electronic device with reflective display, the intensity of the ambient light beam has an important influence on the display brightness. Therefore, the above-mentioned photosensitive module also includes a filtering structure for obtaining the intensity of the ambient light beam, so that the brightness of each light beam in the display light beam can be adjusted based on the intensity of the ambient light beam.

[0099] It should also be noted that when the color gamut range and light intensity of the ambient light beam are sufficient to ensure the display effect of the display screen 200, the first light source 202 and the second light source 204 may not participate in the display, that is, the first light source 202 and the second light source 204 do not emit light beams and are in the off state.

[0100] Accordingly, the present application also provides a processing method, which can be applied to an electronic device, which can be any electronic device described in any of the above embodiments, including a display screen 100 and a backlight module 200. The backlight module 200 includes a first light source 202 and a second light source 204. The first light source 202 is a full-spectrum light source, and the second light source 204 emits a light beam of at least one color. Figure 10 As shown, Figure 10 A flowchart of a processing method provided in this application, the processing method comprising:

[0101] S1: issuing a display instruction to the backlight module 200. The backlight module 200 responds to the display instruction and controls at least one of the first light source 202 and the second light source 204 to emit a light beam to form a display light beam.

[0102] S2: Controlling the display screen 100 to realize target display at least based on the display light beam.

[0103] The color gamut range of the display light beam includes at least one of the color gamut range of the first light beam and the color gamut range of the second light beam, and if the display light beam includes the second light beam, the color gamut range of the display light beam changes as the color gamut range of the second light beam changes.

[0104] Based on the above, it can be seen that when controlling an electronic device to display, this processing method can achieve display using either full-spectrum white light or by coordinating full-spectrum white light with at least one of the three primary colors of red, green, and blue. When display is achieved using full-spectrum white light and at least one of the three primary colors of red, green, and blue, that is, when the display beam includes a first light beam and a second light beam, it is known that the color gamut of the display beam can change with changes in the color gamut of the second light beam. Specifically, the color gamut of the display beam can change with changes in the portion of the second light beam's color gamut that is outside the color gamut of the first light beam. For example, if the color gamut of the portion of the second light beam that is outside the color gamut of the first light beam decreases, the color gamut of the display beam decreases. Alternatively, if the color gamut of the portion of the second light beam that is outside the color gamut of the first light beam increases, the color gamut of the display beam increases. In other words, the color gamut of the second light beam and changes in its color gamut can change the color gamut of the display beam, that is, the color gamut of the display beam can change with changes in the color gamut of the second light beam. For example, if the target display of an electronic device is a picture or video with a high color gamut, and the first light beam cannot meet the color gamut requirements of the target display, a second light beam can be added to the first light beam to change the color gamut range of the actual light beam to meet the target display requirements and achieve a target display with a higher color gamut. Furthermore, when the target display has a higher color gamut range, the color gamut range of the second light beam can be changed to make the second light beam's color gamut range even larger, further increasing the color gamut range of the display light beam and achieving a target display with a higher color gamut requirement.

[0105] Therefore, when the electronic device realizes the display function, it can realize the display based on the full-spectrum light beam or based on the full-spectrum light beam and the second light beam in coordination. When the electronic device realizes the display based on the full-spectrum light beam and the second light beam in coordination, the processing method can control the electronic device to use the full-spectrum light beam as the basis and adjust the color gamut range of the display light beam according to the color gamut requirements of the target display, thereby realizing a display function based on the full-spectrum light beam and with an adjustable color gamut range, which can be applicable to a variety of application scenarios with different color gamut requirements.

[0106] Since the full-spectrum light beam can better protect the user's eyes, the processing method realizes a display function based on the full-spectrum light beam and with adjustable color gamut through the above-mentioned first light source 202 and second light source 204, so that it can be applied to a variety of application scenarios with different color gamut requirements. While being applicable to a variety of application scenarios with different color gamut requirements, it also takes into account the user's vision health.

[0107] Furthermore, it is known that when the electronic device performs a display, the display beam can be formed by the second light beam emitted by the second light source 204, that is, the electronic device can also display using the three primary colors of red, green, and blue. In other words, when the electronic device performs a display, it can display using full-spectrum white light, or it can display using the combination of full-spectrum white light and at least one of the three primary colors of red, green, and blue, or it can display using the three primary colors of red, green, and blue. In other words, this processing method can control the electronic device to display in a variety of display modes, can adapt to a variety of application scenarios, and has strong practicality.

[0108] In one embodiment of the present application, the backlight module 200 further includes a light guide structure 206, the first light source 202 and the second light source 204 are disposed on the light guide structure 206, and the light guide structure 206 is located on the non-display side of the display screen 100. Figure 11 As shown, Figure 11 This is a flowchart of a processing method provided by the present application. The display screen 100 realizes target display based on at least a display light beam, including:

[0109] The display screen 100 can realize target display based on the display light beam.

[0110] Based on the above, if Figure 12 As shown, Figure 12 This is a flowchart of a processing method provided in the present application. The method sends a display instruction to the backlight module 200 to control at least one of the first light source 202 and the second light source 204 to emit a light beam to form a display light beam. The method includes:

[0111] S11: Acquire a first target color gamut, where the first target color gamut is a color gamut range corresponding to a target display, that is, the first target color gamut is a color gamut requirement when the display screen 100 realizes a display function.

[0112] S12: Compare the first target color gamut with the color gamut range of the first light beam, that is, compare the first target color gamut with the color gamut range of the basic light beam displayed on the display screen.

[0113] S13: If Figure 12 As shown, if the first target color gamut is within the color gamut of the first light beam, that is, the first target color gamut is equal to or smaller than the color gamut of the first light beam, then display can be achieved using the first light beam. Therefore, if the first target color gamut is within the color gamut of the first light beam, a first display instruction can be issued to the backlight module 200, controlling the first light source 202 to emit the first light beam to form a display beam. At this time, the color gamut of the display beam includes the first target color gamut, thereby meeting the color gamut requirements of the target display and achieving the target display.

[0114] S14: Figure 13 As shown, Figure 13This is a flowchart of a processing method provided by the present application. If the color gamut range of the first light beam is smaller than the first target color gamut, that is, the first target color gamut exceeds the color gamut range of the first light beam, then the first light beam alone cannot meet the color gamut requirements of the display screen when displaying. A second light beam needs to be added to the display light beam to expand the color gamut range of the display light beam to meet the color gamut requirements of the target display. Therefore, if the color gamut range of the first light beam is smaller than the first target color gamut, a second display instruction is sent to the backlight module 200 to control the first light source to emit the first light beam and the second light source to emit the second light beam to form a display light beam, so that the color gamut range of the display light beam is larger, and then the color gamut range of the display light beam can include the first target color gamut, so as to meet the color gamut requirements of the target display and achieve the target display.

[0115] In addition, in another embodiment of the present application, if the color gamut range of the first light beam is smaller than the first target color gamut, that is, the first target color gamut exceeds the color gamut range of the first light beam, a second light beam that meets the first target color gamut can also be emitted by a second light source to form a display beam to achieve target display.

[0116] In one embodiment of the present application, Figure 14 As shown, Figure 14 This is a flow chart of a processing method provided by the present application. If the color gamut range of the first light beam is smaller than the first target color gamut, a display instruction is issued to the backlight module 200 to control the first light source to emit the first light beam and the second light source to emit the second light beam to form a display light beam. The method also includes:

[0117] S141: Obtain a first difference, where the first difference is the difference between the color gamut range of the second light beam and the color gamut range of the first light beam, specifically the difference between the boundary point of the color gamut range of the second light beam and the corresponding boundary point of the color gamut range of the first light beam. Figure 2As shown, if the color gamut range of the second light beam is larger than the color gamut range of the first light beam, the first difference may include RR', GG', and BB'. If only certain areas of the color gamut range of the second light beam, such as the red light area, are outside the color gamut range of the first light beam, then the first difference may include RR', and so on. It should be noted that if the color gamut ranges of the first and second light beams are within a certain value range, that is, the color gamut range of the first light beam includes its maximum color gamut range, minimum color gamut range, and the intermediate color gamut range therebetween, and the color gamut range of the second light beam includes its maximum color gamut range, minimum color gamut range, and the intermediate color gamut range therebetween, the first difference may be the difference between the maximum color gamut range of the first light beam and the maximum color gamut range of the second light beam, or the difference between the minimum color gamut range of the first light beam and the minimum color gamut range of the second light beam, or the difference between the intermediate color gamut range of the first light beam and the corresponding intermediate color gamut range of the second light beam, that is, the first difference is the difference between the color gamut range of the first light beam and the color gamut range of the second light beam to a corresponding degree.

[0118] S142: Divide the first difference into N equal parts to obtain N-1 preset color gamuts, where the color gamut ranges of the N-1 preset color gamuts gradually increase. N is an integer greater than or equal to 2, and each of the N preset color gamuts includes both the color gamut range of the first light beam and the portion of the color gamut range of the second light beam that is outside the color gamut range of the first light beam. It should be noted that when dividing the first difference into N equal parts, linear division can be used, i.e., the differences between the color gamut ranges of the N-1 preset color gamuts are the same, or JNCD (Just Noticeable Color Difference) division can be used, i.e., division is performed based on the degree of color change, i.e., the degree of color change of the N-1 preset color gamuts is the same. This application does not limit this, and the specific situation will determine it.

[0119] S143: Compare the color gamut ranges of the N-1 preset color gamuts with the first target color gamut, and obtain a preset color gamut among the N-1 preset color gamuts that is closest to the first target color gamut and is not smaller than the first target color gamut.

[0120] S144: Based on the obtained preset color gamut, obtain the color gamut range of the second light beam in the target light beam. It is known that each of the N preset color gamuts includes both the color gamut range of the first light beam and the portion of the color gamut range of the second light beam that is outside the color gamut range of the first light beam. Therefore, based on the difference between the preset color gamut and the color gamut range of the first light beam, the necessary components of the color gamut range of the second light beam can be obtained. In other words, the color gamut range of the second light beam at least includes the difference between the preset color gamut and the color gamut range of the first light beam, thus obtaining the color gamut range of the second light beam.

[0121] S145: Based on the color gamut range of the second light beam obtained above, a second display instruction is issued to the backlight module 200. The backlight module 200 responds to the second display instruction, controls the first light source 202 to emit the first light beam, and controls the second light source 204 to emit the second light beam to form a display beam.

[0122] Based on the above, it can be seen that when the color gamut range of the first light beam cannot meet the color gamut requirements of the display screen, the difference between the color gamut range of the first light beam and the color gamut range of the second light beam can be divided equally to obtain N-1 preset color gamuts. The first target color gamut, i.e., the color gamut range of the display screen during display, is compared with the color gamut range of the N-1 preset color gamuts to obtain the preset color gamut that is closest to the first target color gamut among the N-1 preset color gamuts. Based on the preset color gamut that is closest to the first target color gamut, the color gamut range of the second light beam in the display light beam can be obtained, so that the color gamut range of the second light beam in the display light beam can be accurately adjusted to make the color gamut range of the second light beam moderate, thereby meeting the color gamut requirements of the target display and achieving the target display without causing the problem of the second light beam's color gamut being too large and affecting the display effect.

[0123] In one embodiment of the present application, Figure 15 As shown, Figure 15 This is a flowchart of a processing method provided by the present application. The display screen 100 realizes target display based on at least a display light beam, including:

[0124] S21: During a first time period, the display screen 100 realizes a first target display based on at least the display light beam, wherein during the first time period, the display color gamut range of the display screen 100 is fixed.

[0125] S22: During a second time period, the display screen 100 realizes a second target display based at least on the display light beam, wherein during the second time period, the display color gamut range of the display screen 100 is fixed.

[0126] S23: Obtaining a second difference value, where the second difference value is the difference between the color gamut range corresponding to the first target display and the color gamut range corresponding to the second target display. It should be noted that the second difference value may be the maximum difference between the color gamut range corresponding to the first target display and the color gamut range corresponding to the second target display. In other words, when the differences between different regions of the color gamut ranges of the first target display and the second target display are different, the maximum difference value is used as the second difference value.

[0127] S24: If the second difference is greater than the first preset value, a third time period is obtained based on the first preset value, and within the third time period, the display screen 100 gradually transitions from the first target display to the second target display.

[0128] It should be noted that the first time period can be the duration of the current target display, the second time period can be the duration of the next target display, and the third time period is the time period for the current target display to transition to the smaller target display. It should also be noted that the above-mentioned first preset value can be the color gamut change value when the human eye can clearly perceive the color jump of the display screen, and the third preset time period can be based on the above-mentioned second difference, so that the color gamut range of the first target display changes to the color gamut range of the second target display at a certain rate of change. It should be noted that the first time period can be the duration of the current target display, the second time period can be the duration of the next target display, and the third time period is the time period for the current target display to transition to the smaller target display, that is, within the third time period, the display content of the display screen 100 gradually transitions from the first target display to the second target display, that is, the third time period corresponds to the time period between the end time of the first target display and the start time of the second target display.

[0129] As can be seen from the above, when the color gamut of display screen 100 changes due to factors such as switching display content, the switching time can be adjusted based on the color gamut difference, that is, based on the degree of change in the color gamut. In other words, the color gamut transition time can be adjusted based on the degree of change in the color gamut. Specifically, if the color gamut change is large, the switching time is long, while if the color gamut change is small, the switching time is short. This ensures a smooth transition of the color gamut when display screen 100 switches screens, which is reflected in the smoothness of the screen switching and improves the user experience.

[0130] It should be noted that the color gamut range of the first target display can be within the color gamut range of the first light beam, or can be larger than the color gamut range of the first light beam. Similarly, the color gamut range of the second target display can be within the color gamut range of the first light beam, or can be larger than the color gamut range of the first light beam. Alternatively, the first target display and the second target display can also be displayed using the three primary colors of red, green, and blue. This application does not impose any restrictions on this. As long as the color gamut difference between the first target color gamut and the second target color gamut is too large, the third time period can be set to enable the display screen 100 to gradually transition from the first target display to the second target display within the transition time period.

[0131] In one embodiment of the present application, the backlight module 200 further includes a light-guiding structure 206, the first light source 202 and the second light source 204 are arranged on the light-guiding structure 206, and the light-guiding structure 206 is located on the display side of the display screen 100. Based on this, the electronic device further includes a photosensitive module, which is located on the display side of the display screen 100 and is located in the non-display area. The photosensitive module may include a photosensitive structure and a filter structure arranged on the photosensitive structure, the photosensitive structure is used to obtain the color gamut range of the ambient light beam, the filter structure is used to obtain the light intensity of the ambient light beam, and the photosensitive structure in the photosensitive module may be a photosensitive structure doped with cerium to achieve a better photosensitivity effect. Based on this structure, as Figure 16 As shown, Figure 16 This is a flowchart of a processing method provided by the present application. The display screen 100 realizes target display based on at least a display light beam, including:

[0132] The display screen 100 realizes target display based on the display light beam and the ambient light beam of the environment where the electronic device is located.

[0133] The step of sending a display instruction to the backlight module 200 to control at least one of the first light source 202 and the second light source 204 to emit a light beam to form a display light beam includes:

[0134] S15: Acquire a second target color gamut, where the second target color gamut is a color gamut range corresponding to the target display.

[0135] S16: Using the photosensitive module to obtain the color gamut of the ambient light beam in the environment in which the electronic device is located, and comparing the second target color gamut with the color gamut of the ambient light beam in the environment in which the electronic device is located. The photosensitive structure in the photosensitive module obtains the light intensity of the ambient light beam in the environment in which the electronic device is located, and the filter structure in the photosensitive module obtains the color gamut of the ambient light beam in the environment in which the electronic device is located.

[0136] S17: If the difference between the second target color gamut and the color gamut range of the ambient light beam is greater than the second preset value and less than the third preset value, a third display instruction is issued to the backlight module 200. In response to the third display instruction, the backlight module 200 controls the first light source 202 to emit the first light beam to form a display beam. That is, when the difference between the second target color gamut and the color gamut range of the ambient light beam is not large, the display screen 100 can achieve the target display based on the first light beam and the ambient light beam in the environment where the electronic device is located. It should be noted that the ambient light beam that can be used for display is usually visible light, such as natural light and lamplight. Therefore, the color gamut range of the full-spectrum light beam is greater than the color gamut range of the ambient light beam in the environment where the electronic device is located. Therefore, when the difference between the second target color gamut and the color gamut range of the ambient light beam is not large, the display screen 100 can achieve the target display based on the first light beam and the ambient light beam in the environment where the electronic device is located. It should be noted that the above-mentioned second preset value and third preset value can be determined based on the difference between the color gamut range of the first light beam and the color gamut range of the ambient light beam. Specifically, the above-mentioned second preset value can be the difference between the minimum color gamut range of the first light beam and the color gamut range of the ambient light beam, and the third preset value can be the difference between the maximum color gamut range of the first light beam and the color gamut range of the ambient light beam. Therefore, when the difference between the second target color gamut and the color gamut range of the ambient light beam is within the range between the second preset value and the third preset value, the first light beam and the ambient light beam can be used to achieve target display.

[0137] S18: If the difference between the second target color gamut and the color gamut range of the ambient light beam is greater than or equal to a third preset value, obtaining the color gamut range of the display light beam based on the difference between the second target color gamut and the color gamut range of the ambient light beam;

[0138] S19: Based on the acquired color gamut range of the display light beam, acquire the color gamut range of the second light beam in the display light beam.

[0139] S20: Based on the acquired color gamut range of the second light beam, a fourth display instruction is issued to the backlight module 200. The backlight module 200 responds to the fourth display instruction, controls the first light source to emit the first light beam, and controls the second light source to emit the second light beam to form a display beam.

[0140] It should be noted that when the difference between the second target color gamut and the color gamut range of the ambient light beam is too large, the color gamut requirements can no longer be met by simply adding the first light beam, and the color gamut range needs to be further expanded. In this case, a second light beam needs to be added to the display light beam. The display screen 100 can achieve target display based on the ambient light beam of the environment in which the electronic device is located and the display light beam including the first light beam and the second light beam.

[0141] It should also be noted that since the first light beam is a full-spectrum light beam, the color gamut range is known, and the above-mentioned display light beam is obtained by adding the second light beam to the first light beam, so that the color gamut range of the display light beam is known, the color gamut range of the second light beam is also known, and therefore the color gamut range of the second light beam can be obtained based on the color gamut range of the display light beam.

[0142] In one embodiment of the present application, Figure 17 As shown, Figure 17 A flowchart of a processing method provided in this application, which uses a photosensitive module to obtain the color gamut range of the ambient light beam in the environment where the electronic device is located, includes:

[0143] S161: Periodically obtain a color gamut range of an ambient light beam in an environment where the electronic device is located.

[0144] S162: If the difference between the color gamut range of the ambient light beam in the environment where the electronic device is located obtained in the current cycle and the color gamut range obtained in the previous cycle is greater than a fourth preset value, the second target color gamut is compared with the color gamut of the ambient light beam in the environment where the electronic device is located obtained in the current cycle.

[0145] It should be noted that when the difference between the color gamut range of the ambient light beam obtained in the current cycle and the color gamut range of the ambient light beam obtained in the previous cycle is greater than the fourth preset value, it means that the color gamut range of the display light beam formed by the current ambient light beam and the first light beam, or the ambient light beam and the second light beam, or the ambient light beam and the first and second light beams, no longer meets the color gamut requirements of the target display. Therefore, the color gamut range of the display light beam needs to be adjusted based on the color gamut range of the ambient light beam obtained in the current cycle to meet the color gamut requirements of the target display. It should also be noted that regarding the fourth preset value, if the display light beam includes the ambient light beam and the first light beam, the fourth preset value is determined based on the color gamut range of the ambient light beam obtained in the current cycle and the color gamut range of the first light beam. If the display light beam includes the ambient light beam and the second light beam, or the display light beam includes the ambient light beam, the first light beam, and the second light beam, the fourth preset value is determined in the same manner as described above, based on the color gamut range of the ambient light beam obtained in the current cycle and the color gamut range of the compensation light beam. The compensation light beam is the light beam in the display light beam excluding the ambient light beam.

[0146] Because the color gamut of the ambient light beam changes, it is necessary to periodically obtain the color gamut of the ambient light beam. That is, it is necessary to obtain the color gamut of the ambient light beam at regular intervals to reflect the color gamut of the ambient light beam in real time. Therefore, when the difference between the color gamut of the ambient light beam in the environment of the electronic device obtained in the current cycle and the color gamut obtained in the previous cycle is too large, it is necessary to compare the second target color gamut with the color gamut of the ambient light beam in the environment of the electronic device obtained in the current cycle. That is, the color gamut of the ambient light beam obtained in the current cycle is used to represent the color gamut of the ambient light beam, so as to reflect the color gamut of the ambient light beam in real time and ensure the display effect.

[0147] It should be noted that if the color gamut range of the ambient light beam obtained in the current cycle differs significantly from the color gamut range of the ambient light beam obtained in the previous cycle, and if the color gamut range of the display light beam is not compensated by the first and / or second light beams, resulting in a significant color jump in the displayed image due to the excessive change in the color gamut range of the display light beam, it is also necessary to obtain a transition time to the color gamut range of the current cycle based on the difference between the color gamut range of the ambient light beam in the current cycle and the color gamut range of the ambient light beam in the previous cycle. The specific method is similar to the transition method between the first target display and the second target display described above and will not be repeated here.

[0148] The various embodiments in this specification are described in a progressive, parallel, or combined manner. Each embodiment focuses on the differences from other embodiments, and reference can be made to the descriptions of the embodiments for similar or identical areas.
