These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0047] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0048] It should be noted that the brief descriptions of terms in this application are only for the purpose of facilitating the understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and usual meanings.

[0049] In addition, the terms "comprises" and "comprising" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0050] The following are the explanations of the terms used in this application:

[0051] Color gamut: refers to the range of colors that can be expressed by a certain color representation mode, and also refers to the range of colors that can be expressed by specific devices such as monitors, printers, and other printing and reproduction devices.

[0052] System on Chip (SOC): This refers to the integration of multiple complex circuit components onto a single chip, including a central processing unit (CPU), graphics processing unit (GPU), memory, and various input and output interfaces, forming a complete system and achieving a high degree of integration. In display devices such as televisions, the SOC is the core processor, controlling all functions of the TV, including image processing, sound, network connectivity, and the operating system.

[0053] On-screen display (OSD) adjustment method: Generally, a rectangular menu of various adjustment items of the display device pops up on the display module such as the display screen after pressing the menu button of the display device. Through this menu, various working indicators of the display module, including color, mode, geometry, etc., can be adjusted to achieve the target usage state.

[0054] Chromaticity coordinates are the coordinates of color, also called colorimetric coordinates. Commonly used color coordinates have the x-axis on the horizontal axis and the y-axis on the vertical axis. With these coordinates, we can identify a point on a chromaticity diagram. This point accurately represents the color of the light emitted. In other words, the chromaticity coordinates precisely represent the color.

[0055] The following is an exemplary description of the architecture and imaging principle of the display device. It should be understood that the display device mentioned in this application can be a projection device (such as a laser projection device) or a display device with a display screen, such as a television, a computer, etc.

[0056] Figure 1 A schematic diagram of the structure of a display device, such as Figure 1 As shown, the display device includes: a processing module 1, a light source driving module 2, a display module 3, and a light source module 4. It should be understood that Figure 1 Only part of the structure of the display device is shown, and structures not related to this application are not shown.

[0057] The processing module 1 is used to obtain an input signal to be displayed, such as a video stream, process the input signal, and then send the processed input signal to the display module 3 and the light source driver module 2. The light source driver module 2 controls the light source module to emit light according to the processed input signal, so as to display the input signal through the display module 3.

[0058] In some embodiments, the processing module 1 may be equipped with a core of the display device. The core may be, for example, a system on chip (SOC). The light source driver module 2 may be, for example, any chip for driving a light source. The display module 3 may vary depending on the display device. For example, if the display device is a display device with a display screen, such as a television or a computer, the display module 3 may be, for example, a display screen; if the display device is a projection device, the display module 3 may be, for example, a display module including a projection lens. The light source module 4 may be any device that can serve as a light source, such as a laser light source or an LED light source, and this application does not limit it.

[0059] At present, after obtaining the input signal, the processing module 1 of the display device controls the light source module 4 to emit light source for imaging through the light source driving module 2 according to the input signal. The color gamut presented by the pure color light source of the display device itself may be different from the color gamut of the input signal. For example, the current color gamut formats of the input signal are sRGB, DCI-P3, NTSC and BT2020, and the display device using R, G, and B three-color light sources has a color gamut size far exceeding the sRGB color gamut, especially the display device using R, G, and B three-color laser light sources, whose display color gamut size may exceed BT2020. This results in that when the input signal is a small color gamut such as sRGB, if the color gamut conversion is not performed, the color will be greatly distorted, affecting the display quality of the input signal.

[0060] In the prior art, there are also examples of using color gamut conversion to achieve a better display of input signals. However, these technologies generally only adjust the display color gamut of the input signal, while failing to perform color gamut conversion on the display device's OSD. This results in a difference between the color gamut of the input signal and the color gamut of the OSD, which in turn affects the user's viewing experience.

[0061] In view of this, the present application provides a display device, which determines the lighting strategy of the light source of the display device according to the original color gamut of the input signal and the target color gamut, and controls the light source module 4 to emit light through the lighting strategy, so that the display device can display the input signal in the target color gamut, avoiding the color distortion problem caused by the inconsistency between the color gamut of the input signal and the color gamut presented by the pure color light source of the display device. In addition, since the method provided by the present application is to adjust the lighting strategy of the incident light source, which is equivalent to fundamentally changing the incident mode of the light source of the display device, it can not only convert the color gamut of the input signal, but also convert the color gamut of the OSD, so as to achieve consistency between the color gamut of the input signal and the color gamut of the OSD, thereby improving the user's viewing experience.

[0062] The technical solutions of the present application and the technical solutions of the present application are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. In the description of this application, unless otherwise clearly specified and defined, each term should be understood in a broad sense in this field. The embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood that this application does not limit the type of the display device. For example, the display device can be, for example, a television, a monitor, a touch panel, an intelligent electronic panel, a mobile phone, etc., or it can be a projection device, such as a laser projection device.

[0063] Continue to refer to Figure 1 , the display device provided in this embodiment may be Figure 1The display device shown can also be any device including Figure 1 The display device of the structure shown includes: a processing module 1 , a light source driving module 2 , a display module 3 , and a light source module 4 .

[0064] Based on the above structure, this application provides a display method. Figure 2 This is a flow chart of a display method provided by the present application, which is applied to the processing module 1 of the display device, such as Figure 2 As shown, the method includes the following steps:

[0065] S101: Acquire an input signal.

[0066] In this step, the processing module 1 obtains an input signal to perform subsequent color gamut adjustment according to the input signal.

[0067] The above-mentioned input signal may be, for example, a video stream. The processing module 1 may obtain the input signal from a storage medium or may obtain the input signal transmitted through a network, which is not limited in this application.

[0068] S102: Determine the original color gamut of the input signal according to the input signal.

[0069] The input signal usually includes its own color gamut properties. In this step, the processing module 1 determines the original color gamut of the input signal, that is, the color gamut corresponding to the input signal itself, based on the input signal, and can subsequently adjust the original color gamut of the input signal accordingly.

[0070] S103: Determine a lighting strategy for at least one light source of the display device according to the original color gamut and the target color gamut.

[0071] The above-mentioned target color gamut is the color gamut corresponding to the image to be displayed on the display module 3. This application does not limit the specific color gamut type of the target color gamut, which is determined according to actual needs. In some embodiments, the processing module 1 can obtain the target color gamut based on the display parameters of the display device. The above-mentioned display parameters can be preset or obtained from user input. For example, the processing module 1 can store a mapping relationship between display parameters and color gamut, and the processing module 1 obtains the target color gamut based on the display parameters and the above-mentioned mapping relationship. Alternatively, the processing module 1 can directly receive the target color gamut input by the user.

[0072] Different display devices may have different numbers of light sources, but each display device has at least one light source. In this step, the processing module 1 determines a lighting strategy for at least one light source based on the original color gamut and the target color gamut, and then uses the lighting strategy to control the light source module 4 to emit light.

[0073] For example, the above-mentioned lighting strategy may include a target control current magnitude and a target lighting timing of at least one light source of the display device. This application does not limit the specific values ​​of the target control current magnitude and the target lighting timing. The control current magnitude of the light source affects the chromaticity of the color rendered by the light source. By adjusting the control current magnitude and lighting timing of the light source, the color coordinates of the final color rendered can be changed, thereby achieving adjustment of the color gamut of the display device.

[0074] In some embodiments, processing module 1 may store a color gamut lookup table, for example, which includes a mapping relationship between an original color gamut, a target color gamut, and an illumination strategy of a light source. Processing module 1 may determine an illumination strategy for at least one light source of a display device based on the original color gamut, the target color gamut, and the color gamut lookup table.

[0075] In some embodiments, the processing module 1 may first determine, based on the target color gamut, set values ​​for the color coordinates of the primary colors of the target color gamut, and then, based on the set values ​​and the color coordinates of the primary colors of the original color gamut, obtain a lighting strategy for at least one light source of the display device. For example, the lighting strategy may be used to adjust the control current and lighting timing of the light source of the display device, so that the color coordinates of the primary colors presented by the light source of the display device after adjustment are the set values ​​for the color coordinates of the primary colors of the target color gamut.

[0076] S104 , sending the lighting strategy to the light source driving module 2 , so that the light source driving module 2 drives the light source module 4 to emit light according to the lighting strategy, and then displays the input signal according to the target color gamut through the display module 3 .

[0077] In this step, the processing module 1 controls the light source driving module 2 to drive the light source module 4 to emit light according to the light-emitting strategy, and then displays the input signal according to the target color gamut through the display module 3, that is, the color gamut of the incident light source can be adaptively adjusted according to actual needs, and thus can be better adapted to the original color gamut of the input signal.

[0078] In this embodiment, processing module 1 determines the original color gamut of the input signal based on the input signal. Then, based on the original color gamut and the target color gamut, it determines a lighting strategy for at least one light source of the display device. This lighting strategy is then transmitted to light source driver module 2, causing light source driver module 2 to drive light source module 4 to emit light according to the lighting strategy, thereby allowing display module 3 to display the input signal according to the target color gamut. Through this method, processing module 1 can adjust the color gamut of the display device based on the lighting strategy, so that the color gamut of the display device can adapt to the original color gamut of the input signal, thereby achieving better display of the input signal and improving display quality.

[0079] In addition, since the method provided in the present application is to adjust the light-emitting strategy of the incident light source, which is equivalent to fundamentally changing the light source incident method of the display device, it is possible not only to convert the color gamut of the input signal, but also to realize the conversion of the color gamut of the OSD, thereby achieving consistency between the color gamut of the input signal and the color gamut of the OSD, and improving the user's viewing experience.

[0080] The following takes the lighting strategy including the target control current size and target lighting timing of at least one light source of the display device as an example to illustrate how to achieve color gamut conversion through the lighting strategy, that is, to display the input signal according to the target color gamut through the display module 3.

[0081] As mentioned above, the magnitude of the light source's control current and the timing of its light emission affect the display device's final color gamut. For example, consider a display device using red, green, and blue light sources. Each of these three light sources has its own corresponding color coordinates. If the color of one or more other light sources can be incorporated into the light emitted by any of these three light sources, the color coordinates of the final color can be altered, ultimately transforming the display device's color gamut.

[0082] Figure 3 This is a schematic diagram of a light source control current and light emission timing provided in this application. Figure 4 This is a schematic diagram of a light source controlling current provided in this application. Figure 3 and Figure 4 This is a schematic diagram taking the light source as an RGB light source as an example. Figure 4 is a schematic diagram using a red light source as an example. Figure 4 As shown, before the color gamut conversion is performed according to the lighting strategy, between time t1 and time t2, only the red light source emits light; Figure 3 and Figure 4 As shown, after color gamut conversion is performed according to the lighting strategy, between time t1 and t2, when the red light source emits light, the green and blue light sources also emit light slightly. In this way, the color coordinates of the red primary color of the display device can be adjusted. Similarly, the color coordinates of all light sources of the display device can be adjusted, so that the display module 3 can display the input signal according to the target color gamut based on the adjusted light sources.

[0083] The following is an exemplary description of how the processing module 1 specifically determines the lighting strategy of at least one light source of the display device according to the original color gamut and the target color gamut, that is, step S103 in the above embodiment.

[0084] As described above, in some embodiments, the processing module 1 may, for example, store a color gamut lookup table, and the processing module 1 may determine the lighting strategy of at least one light source of the display device based on the original color gamut, the target color gamut, and the color gamut lookup table. Table 1 is a possible color gamut lookup table provided in this application. As shown in Table 1, if the original color gamut is Gamut_1 and the target color gamut is Aim_3, the lighting strategy is C_3. It should be understood that Table 1 is only an exemplary display, and this application does not limit the specific mapping method of the original color gamut and the target color gamut to the lighting strategy.

[0085] Table 1

[0086]

[0087]

[0088] In this case, if the lighting strategy includes the target control current size and the target lighting timing, the lighting strategy can be calibrated offline through experiments, or can be calculated using an algorithm and then added to the color gamut lookup table.

[0089] Optionally, in some embodiments, if the display device supports conversion into multiple color gamuts, the processing module 1 may further first obtain a color gamut lookup table corresponding to the target color gamut from the color gamut lookup table list based on the target color gamut, and then find the lighting strategy of at least one light source of the display device corresponding to the original color gamut from the color gamut lookup table. For example, in this implementation, the color gamut lookup table may be as shown in Table 2.

[0090] Table 2

[0091] Original color gamut Target color gamut Luminous Strategy Gamut_1 Aim_1 C_1 Gamut_2 Aim_1 C_2 Gamut_3 Aim_1 C_3 Gamut_4 Aim_1 C_4 …… …… …… Gamutón Aim_1 C_n

[0092] Optionally, in some embodiments, the processing module 1 may further obtain configuration parameters, which are used to configure the mapping relationship between the original color gamut and the target color gamut and the luminous strategy of the light source. The processing module 1 may update the color gamut lookup table according to the configuration parameters. The configuration parameters may be input by the user, or may be obtained by the processing module 1 from other electronic devices (such as computers) or storage media. Through this implementation, flexible configuration of the luminous strategy in the color gamut lookup table can be achieved, thereby improving the usability and flexibility of the display method provided in this application.

[0093] In this embodiment, the lighting strategy of at least one light source of the display device is pre-configured in a color gamut lookup table, rather than being calculated in real time. Therefore, through the above implementation, processing module 1 can quickly find the lighting strategy of at least one light source of the display device corresponding to the original color gamut and the target color gamut using the color gamut lookup table. This is fast and efficient, enabling rapid conversion of the display device's color gamut.

[0094] The following takes the example of a lighting strategy including a target control current size and a target lighting timing of at least one light source of a display device to exemplify how the processing module 1 determines the lighting strategy of at least one light source of the display device based on the original color gamut and the target color gamut, that is, step S103 in the above embodiment. Figure 5 A flow chart of the second display method provided in this application is shown as follows: Figure 5 As shown, step S103 may include the following steps:

[0095] S201 : Acquire setting values ​​of color coordinates of primary colors of a target color gamut according to the target color gamut.

[0096] In this step, the processing module 1 obtains the set values ​​of the color coordinates of the primary colors of the target color gamut according to the target color gamut, and then can adjust the lighting strategy of the light source according to the set values.

[0097] Exemplarily, the processing module 1 may store a mapping relationship between the target color gamut and the set values ​​of the color coordinates of the primary colors of the target color gamut, and the processing module 1 may determine the set values ​​of the color coordinates of the primary colors of the target color gamut based on the target color gamut and the above mapping relationship.

[0098] S202 : Obtain a target control current and a target light emission timing of at least one light source of the display device according to the set values ​​of the color coordinates of the primary colors of the target color gamut and the color coordinates of the primary colors of the original color gamut.

[0099] In some embodiments, the processing module 1 can, for example, predict the control current of at least one light source of the display device based on the set values ​​of the color coordinates of the primary colors of the target color gamut, the color coordinates of the primary colors of the original color gamut, and a current prediction model. The current prediction model can, for example, be a model trained using any machine learning model with the set values ​​of the color coordinates of the primary colors of the target color gamut and the color coordinates of the primary colors of the original color gamut during the manual debugging process as inputs, and the corresponding current as output.

[0100] In this embodiment, the processing module 1 first obtains the set value of the color coordinates of the primary colors of the target color gamut according to the target color gamut; then, based on the set value of the color coordinates of the primary colors of the target color gamut and the color coordinates of the primary colors of the original color gamut, obtains the target control current size and the target light-emitting timing of at least one light source of the display device. Through this implementation method, the processing module 1 can flexibly determine the light-emitting strategy of at least one light source of the display device according to the color coordinates of the primary colors of the original color gamut and the color coordinates of the primary colors of the target color gamut, thereby enabling the color rendering method provided by the present application to be adapted to the color gamut conversion of input signals of all different original color gamuts. The application scenarios of the display method provided by the present application are expanded, thereby better meeting the user's usage needs.

[0101] Figure 6 This is a schematic diagram of a display device provided in an embodiment of the present application. The display device is applied to the processing module 1 in the display device described in any of the above embodiments. The display device includes: an acquisition unit 11, a first determination unit 12, a second determination unit 13, and a display unit 14.

[0102] The acquisition unit 11 is configured to acquire an input signal.

[0104] The second determining unit 13 is configured to determine a lighting strategy of at least one light source of the display device according to the original color gamut and the target color gamut.

[0105] The display unit 14 is used to send the lighting strategy to the light source driving module 2, so that the light source driving module 2 drives the light source module 4 to emit light according to the lighting strategy, and then displays the input signal according to the target color gamut through the display module 3.

[0106] Optionally, the lighting strategy includes: a target control current size and a target lighting timing of at least one light source of the display device; a second determination unit 13, specifically used to obtain the set values ​​of the color coordinates of the primary colors of the target color gamut according to the target color gamut; and obtain the target control current size and the target lighting timing of at least one light source of the display device according to the set values ​​of the color coordinates of the primary colors of the target color gamut and the color coordinates of the primary colors of the original color gamut.
