These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. The word "if," as used herein, may be interpreted as "at … …" or "when … …" or "in response to a determination," depending on the context.
Fig. 1 is a schematic structural diagram illustrating a display panel 100 according to an exemplary embodiment. As shown in fig. 1, the display panel 100 may include a chip assembly 1, and the chip assembly 1 may be configured to switch a display mode of the display panel 100 according to a refresh frequency of a display screen of the display panel 100, where the display mode may include a color display mode and a black and white display mode. For example, assuming that a user views image information using an electronic device equipped with the display panel 100, when the user views video information with a fast refresh frequency, the display panel 100 may be switched to a color display mode, and when the user views text information with a slow refresh frequency, the display panel 100 may be switched to a black-and-white display mode, so that on one hand, power consumption of the user when viewing the text information may be reduced, and on the other hand, when the refresh frequency is low, the black-and-white display mode may be adopted to reduce the influence on the eyes of the user, thereby improving comfort.
Specifically, the chip assembly 1 can determine the refresh frequency of the display panel from the number of image frames of the display screen per unit time. For example, when the number of frames per unit time is large such that the refresh frequency of the display screen exceeds the preset frequency, the display panel 100 may switch to the color display mode, and when the number of frames per unit time is small such that the refresh frequency of the display screen is less than or equal to the preset frequency, the display panel 100 may switch to the black-and-white display mode.
In this embodiment, as shown in fig. 1 and fig. 2, the display panel 1 may further include a pixel layer 2, the pixel layer 2 may include a plurality of pixels, each pixel may include a first sub-pixel and a second sub-pixel, the first sub-pixel may include one or more sub-pixels of electronic ink, and the second sub-pixel is different from the first sub-pixel. For example, as also shown in fig. 2, the pixel layer 2 may include a first pixel 21 and a second pixel 22, the first pixel 21 may include a first sub-pixel 211 and second sub-pixels 212, 213, and 214, and the second pixel 22 may include a first sub-pixel 221 and second sub-pixels 222, 223, and 224. The first sub-pixel 211 and the first sub-pixel 221 may include an electronic ink sub-pixel, so that a black and white display mode of the display panel 100 may be implemented by the first sub-pixel in the pixel layer 2, thereby avoiding blue light and protecting eyes. The second sub-pixels 212, 213, and 214 may be a red sub-pixel, a blue sub-pixel, and a green sub-pixel, respectively, and the second sub-pixels 222, 223, and 224 may also be a red sub-pixel, a blue sub-pixel, and a green sub-pixel, respectively. Of course, in other embodiments, the second sub-pixel may also include other color pixels, such as a yellow sub-pixel, and the like, which is not limited by the disclosure.
Further, each electronic ink sub-pixel may include a black particle cell and a white particle cell, and the white particle cell of each electronic ink sub-pixel is closer to the display side of the display panel 100 than the black particle cell when the display panel 100 is in the color display mode. Based on this, when the display panel 100 is in the black-and-white display mode, the white particle unit of the electronic ink sub-pixel is closer to the display side of the display panel 100, so that the electronic ink sub-pixel can be understood as a white pixel, and the white pixel is mixed with the second color sub-pixel to show the image information.
As shown in fig. 3, when the display panel 100 is in the black-and-white display mode, the second sub-pixel may be switched to the non-operating state, and at least one or the first sub-pixel may be a state in which the white particle unit is closer to the display side of the display panel 100 than the black particle unit, and the black particle unit of at least one or more of the first sub-pixels is closer to the display side of the display panel 100 than the white particle unit, so that the display panel exhibits a black-paper white character or a white-paper black character, and the disclosure is not limited thereto.
In the above embodiments, as shown in fig. 1 and fig. 2, the display panel 100 may further include a liquid crystal layer 3 and a thin film transistor layer 4, the liquid crystal layer 3 may be stacked on the pixel layer 2, the thin film transistor layer 4 may be stacked on the liquid crystal layer 3, the liquid crystal layer 3 is located between the pixel layer 2 and the thin film transistor layer 4, and the thin film transistor layer 4 may be connected to each pixel to control a switching state of each pixel.
Based on the display panel provided in the present disclosure, the present disclosure further provides an electronic device 200 as shown in fig. 4, where the electronic device 200 may include the display panel 100 described in any of the above embodiments, and the display panel 100 may show images or text information for a user to view.
Further, as shown in fig. 5, the present disclosure also provides a switching method of a display mode, as shown in fig. 6, the switching method may include the following steps:
in step 501, a refresh frequency of a display screen of the display panel is obtained.
In this embodiment, the number of image frames of the display screen per unit time may be acquired, and the refresh frequency may be further determined based on the number of image frames per unit time. The switching between two adjacent frames of images in the display screen may be autonomous switching or switching triggered by a user. For example, when the electronic device is playing a dynamic video, the switching between two frames of images is autonomous switching; when a user views image information by using the electronic equipment, the images can be switched by sliding the character interface through fingers.
In step 502, the display mode of the display panel is switched according to the refresh frequency, wherein the display mode includes a color display mode and a black and white display mode.
In this embodiment, when the refresh frequency is less than or equal to a preset frequency, the display panel may be switched to a black-and-white display mode; and when the refreshing frequency is greater than the preset frequency, switching the display panel to a color display mode.
Corresponding to the foregoing embodiments of the method for switching display modes, the present disclosure also provides embodiments of a switching apparatus for display modes.
