For purposes of making the objects, technical solutions, and advantages of the present disclosure more apparent, the principle and spirit of the present disclosure will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are presented merely to enable one skilled in the art to better understand and practice the present disclosure and are not intended to limit the scope of the present disclosure in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In this document, it should be understood that any number of elements in the drawings is for illustration and not limitation, and that any naming is used only for distinction and not for any limitation.

It should be noted that unless otherwise defined, technical or scientific terms used in the embodiments of the present disclosure should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present disclosure pertains. The terms "first," "second," and the like, as used in embodiments of the present disclosure, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed. The article "a" or "an" preceding an element does not exclude the presence of a plurality of such elements.

The principles and spirit of the present disclosure are explained in detail below with reference to several representative embodiments thereof.

As described in the background, the color gamut refers to a range of colors that can be expressed by a certain color rendering mode, and also refers to a range of colors that can be expressed by a specific device, such as a display, a printer, or the like, by printing copy. The color gamut determines the richness of the image and the video color, and if the imaging, transmission and display technology cannot fully cover the color gamut of the image, the chromatic distortion and the color saturation of the image are reduced, so that the quality of the image is deteriorated, the sense of reality is reduced, and the viewing experience of a user is greatly reduced.

However, the inventors of the present disclosure found that, in the related art, referring to fig. 1, a user is generally required to manually select and switch a desired color gamut, where the color gamut switching is implemented in such a manner that a front-end GPU informs a timing controller TCON of a panel of which color gamut is invoked through an I2C, aux channel or high/low of a GPIO level, and the TCON invokes a corresponding color gamut and a color gamut related configuration to perform color calibration in response to a switching instruction, and outputs the color gamut to the panel after conversion, which is inconvenient.

Furthermore, the display device and the system have poor universality, and the system needs to be matched with a specific design.

In order to solve the above-described problems, the present disclosure provides a display apparatus including a display panel, a memory storing computer instructions executable by the processor, and a processor that, when executed, executes the following computer instructions: determining a refresh rate of a picture of the display panel; determining a target color gamut based on the refresh rate of the picture; and controlling the display panel to switch to the target color gamut. According to the method and the device, the automatic switching of the color gamut of the display panel can be achieved based on the refresh rate of the display panel, and convenience in switching the color gamut of the display panel is improved.

Having described the basic principles of the present disclosure, various non-limiting embodiments of the present disclosure are specifically described below.

Referring to fig. 2, a schematic diagram of a structure of a display device according to an exemplary embodiment of the present disclosure is provided.

The display device includes a display panel 210, a memory 220, and a processor 230. Wherein the display panel 210, the memory 220 and the processor 230 are communicatively connected to each other within the display device via a bus 240.

The display panel 210 may employ LEDs/LCD, OLED, TN, VA, IPS.

The LCD (Liquid Crystal Ddisplay) is a "liquid crystal display", and is an imaging device composed of two polarizers, two thin film transistors, a color filter, a light source (fluorescent lamp), and a display panel. LED (Light Emitting Diode), i.e. "light emitting diode", is composed of a number of compounds, which, because of their different chemical properties, can be divided into organic light emitting diodes OLED and electrodeless light emitting diodes LED, which are light emitting devices. An LED is a light emitting device in an LCD display, and corresponds to an LCD including an LED, and corresponds to an LCD in a similar relationship to a CCFL display or an OLED. The LED display panel is actually an LCD liquid crystal display using light emitting diodes as a light source. LEDs and LCDs differ only in their backlight types: LED backlight and CCFL backlight (i.e., fluorescent lamps), respectively, are diodes and cold cathode lamps. Briefly, LCDs and LEDs are two different display technologies, LCDs being displays composed of liquid crystals, and LEDs being displays composed of light emitting diodes.

An OLED (Organic Light-Emitting Diode) displays an Organic laser Light, and an Organic Light Emitting semiconductor (Organic Electroluminescence Display, OLED). The OLED generates visible light through injection or recombination of carriers, belongs to a light emitting device, but unlike an LED, OLED emits light to independently generate red, green and blue colors, and the LED emits light to be required to be folded to emit red, green and blue colors through liquid crystal molecules, so that the OLED has an independent imaging function, that is, can be independently used as a display screen. Since the OLED lighting each pixel is based on each organic molecule, it is also superior in display color and signal response speed, and in addition, the OLED panel does not exhibit a light leakage phenomenon.

TN (Twisted Nematic) twisted nematic panels are a common soft screen in the past, and have the advantages of lowest cost and wide application. TN screen is in a leading position in terms of equipment application and technical maturity because the price is far lower than that of different types of screens such as IPS and VA, and the push-out time is early.

The VA type panel also belongs to a soft screen, and the VA type panel is a VA type panel which displays plum figures only by touching the panel with a finger, and the TN type panel is a TN type panel which displays water waves. VA panels are a relatively large number of panel types used in medium-high-end liquid crystal displays.

The IPS screen panel is hard, and the screen is touched by a finger, so that the picture cannot be deformed. The IPS screen has better performance in color display, visual angle and the like than TN panels, and has good color presentation range and accuracy, and the wide viewing angle is the original advantage of the IPS panel, and no color cast can be generated no matter which angle is watched.

The Memory 220 may be implemented in the form of ROM (Read Only Memory), RAM (Random Access Memory ), static storage device, dynamic storage device, or the like. Memory 220 may store an operating system and other application programs, and when the technical solutions provided by the embodiments of the present specification are implemented in software or firmware, the relevant program codes are stored in memory 220 and invoked for execution by processor 230.

The processor 230 may be implemented by a general-purpose CPU (Central Processing Unit ), a microprocessor, an application-specific integrated circuit (Application Specific Integrated Circuit, ASIC), or one or more integrated circuits, etc. for executing relevant programs to implement the technical solutions provided in the embodiments of the present disclosure.

Bus 240 includes a path to transfer information between the various components of the display device, such as display panel 210, memory 220, and processor 230.

It should be noted that, although the above display device only shows the display panel 210, the memory 220, the processor 230 and the bus 240, in the implementation process, the display device may further include other components necessary for implementing normal operation, for example:

and the input/output interface is used for being connected with the input/output module so as to realize information input and output. The input/output module can be configured in the display device as a component or can be externally connected to the display device to provide corresponding functions. Wherein the input devices may include a keyboard, mouse, touch screen, microphone, various types of sensors, etc., and the output devices may include speakers, vibrators, indicator lights, etc.

And the communication interface is used for being connected with the communication module so as to realize communication interaction between the display device and other equipment. The communication module may implement communication through a wired manner (such as USB, network cable, etc.), or may implement communication through a wireless manner (such as mobile network, WIFI, bluetooth, etc.).

Furthermore, it will be understood by those skilled in the art that the display device may include only the components necessary for implementing the embodiments of the present disclosure, and not all the components shown in the drawings.

In the above exemplary embodiment, a hardware structure of a display device is described, and when the display device is operated, communication between the processor 230 and the memory 220 through the bus 240 will be described, so that computer instructions executed by the processor 230 at the time of operation:

determining a refresh rate of a picture of the display panel 210;

determining a target color gamut based on the refresh rate of the picture;

the display panel 210 is controlled to switch to the target color gamut.

First, definition of refresh rate of a picture of a display panel will be described:

in particular, the refresh rate of a picture of a display panel refers to the number of times the display panel updates the picture per second. Typically, refresh rate is expressed in hertz (Hz). For example, when the refresh rate is 60Hz, the display panel updates the screen 60 times per second.

The higher the refresh rate, the smoother the display of the display panel. This is particularly important for applications requiring fast dynamic response, such as electronic games and video playback. If the refresh rate is too low, blurring and smearing of the pictures displayed by the display panel may occur, which may affect the user experience. In addition to providing a smoother picture, a high refresh rate may also improve the response time of the display panel. The response time of the display panel refers to the time from the receipt of the user input by the display panel to the display-related operation. A high refresh rate may reduce the response time, thereby allowing the display panel to respond more quickly to user input.

In the above, the definition of the refresh rate of the picture of the display panel is described, and the manner of determining the refresh rate of the picture of the display panel will be described below:

referring to fig. 3, in the present exemplary embodiment, in the computer instructions executed by the processor, the determining a refresh rate of a picture of the display panel includes the steps of:

step S310, determining the number of lines of pixels of the picture;

step S320, determining the time for displaying the pixels of a row of the picture;

step S330, calculating a refresh rate of the picture based on the number of lines of pixels of the picture and the time for displaying one line of pixels of the picture.

In this exemplary embodiment, the determining the number of rows of pixels of the picture in the computer instructions executed by the processor includes:

determining the resolution of the picture;

and obtaining the line number of the pixels of the picture based on the resolution of the picture.

In specific implementation, the resolution of the picture refers to:

how many Pixels are in a picture Per Inch characterizes the amount of information stored in the picture, and the resolution of the picture is in units of PPI (Pixels Per Inch).

Taking the resolution of 720P, 1080P, etc. of a picture as an example, it is indicated that "the number of lines of pixels of the picture" is "for example, 720P indicates that the picture has 720 lines of pixels, and 1080P indicates that the picture has 1080 lines of pixels. It should be noted that 720 lines refers to 720 lines of the display area, and for the blanking area (where there is a certain number of lines) that is not displayed, it is not discussed because it is not displayed.

In this exemplary embodiment, the determining, in the computer instructions executed by the processor, a time to display a row of the pixels includes:

and detecting the time of displaying the pixels of one line of the picture through a time sequence controller.

In particular, the timing controller is a device for controlling the progressive execution of a timing sequence, and can sequentially complete a series of preset operations according to a preset timing sequence rule and a certain time step. It is commonly used in control systems for electronic circuits to control and manage circuit components, electronic devices, etc. that are time critical.

The time sequence controller is generally composed of basic modules such as a timer, a counter, a trigger and the like, and realizes time sequence control of the equipment by adjusting the timing, the counting frequency and the triggering mode. The basic working principle can be described as follows: the time sequence controller receives an external clock signal and initializes a timer according to the clock signal; the timer counts time and outputs a specific control signal according to the value of the timer; after the control signal is output, the trigger receives the control signal and generates a new control signal according to a preset logic relationship; the new control signal enters the counter and the timer again, and the new timing and counting are carried out, and the steps are repeated. Through the basic flow, the time sequence controller realizes the one-by-one control of various devices in the electronic circuit, and completes the complex time sequence control operation.

In this exemplary embodiment, the computer instructions executed by the processor calculate a refresh rate of the picture based on a line number of pixels of the picture and the time for displaying pixels of one line of the picture, including:

refresh rate of a picture = 1/number of rows of pixels of a picture/time to display pixels of a row of a picture.

In the above-described exemplary embodiments, one way of determining the refresh rate of the picture of the display panel is described as being implemented based on the time at which the pixels of the display of one line of the picture are detected by the timing controller, however, the present disclosure is not limited thereto, and another way of determining the refresh rate of the picture of the display panel is also provided:

in this exemplary embodiment, the determining, in the computer instructions executed by the processor, a refresh rate of a picture of the display panel includes:

determining a first moment and a second moment corresponding to rising edges or falling edges of two adjacent frame picture signals of the display panel;

a refresh rate of the picture is determined based on a time interval between the first time instant and the second time instant.

In specific implementation, determining a time interval between a frame start signal of a current frame and a frame start signal of a previous frame, and taking the time interval as a period of the current frame start signal;

determining the frequency of the current frame starting signal according to the period of the current frame starting signal; wherein the frequency of the current frame start signal=1/period of the current frame start signal;

and taking the frequency of the current frame start signal as the current refresh rate of the display panel.

In the above-described exemplary embodiments, the manner of determining the refresh rate of the screen of the display panel is described, and the manner of determining the target color gamut based on the refresh rate of the screen will be described below:

in this exemplary embodiment, the determining, in the computer instructions executed by the processor, the target color gamut based on the refresh rate of the screen includes:

judging whether the duration of the refresh rate of the picture is greater than a preset duration threshold;

in response to determining whether a duration of a refresh rate of the picture is greater than a preset duration threshold, the target color gamut is determined based on the refresh rate of the picture.

matching the refresh rate of the picture with a preset refresh rate to obtain a matching result;

the preset refresh rate corresponds to a preset color gamut, and the target color gamut is determined from the preset color gamut based on the matching result.

Referring to fig. 4, in the present exemplary embodiment, in the computer instruction executed by the processor, the matching between the refresh rate of the picture and a preset refresh rate is performed to obtain a matching result, the preset refresh rate corresponds to a preset color gamut, and the target color gamut is determined from the preset color gamut based on the matching result, where the method includes the following steps:
