First acquire the colour value of display area in this embodiment, the user is when using mobile terminal, because the glass apron is transparent, therefore the colour of the display area of observing is display panel's colour in fact. For example, in the RGB color pattern, the colors are generated by changing and superimposing three color channels of Red (Red, R), Green (Green, G) and Blue (Blue, B), each color channel includes 256 levels of brightness from 0 to 255, for example, the color value of black is RGB (0,0,0), white is RGB (255 ), and turquoise is RGB (107,142,35), and the like, and the specific reference may be made to a corresponding color table. Obviously, the color value of the display area may also be represented by other numerical manners, such as but not limited to color modes including CMYK mode (Cyan, Magenta, Yellow, KeyPlate, Cyan, Magenta, Yellow, and location register color, wherein the location register color is black), HSB mode (Hues, Saturation, Brightness), Lab color mode, and the like.
After the color value of the display area is obtained, the target temperature of the thermochromic layer is further calculated in this embodiment. When the color value of temperature sensing discoloration layer in this embodiment matches with the color value of display area, the temperature of temperature sensing discoloration layer, because the scope of display area is great, and the color is probably in constantly changing, so the color value of temperature sensing discoloration layer in this embodiment with the color value of display area matches the specific value and is that the color value of temperature sensing discoloration layer is closer with the color value comparison of display area, for example specifically can be that each item numerical difference of its RGB color value is in 10, also can be that the total of three item numerical differences is no more than 20 etc. the concrete matching relation of phase colour can be set for according to particular case.
The temperature-sensitive color-changing layer is prepared in advance, when the temperature-sensitive color-changing layer is prepared, the corresponding relation between the temperature-sensitive color-changing layer and the temperature of the temperature-sensitive color-changing layer can be measured and established in advance, and after the target temperature is obtained, the target temperature of the temperature-sensitive color-changing layer can be obtained according to the corresponding relation.
And 303, controlling the temperature of the temperature-sensitive color-changing layer to be the target temperature through the temperature control assembly.
After obtaining the target temperature of temperature sensing discoloration layer, then the temperature through temperature control subassembly control temperature sensing discoloration layer is target temperature, and the colour of temperature sensing discoloration layer can change along with temperature variation, and when the temperature variation of temperature sensing discoloration layer was to target temperature, its colour can change to the colour value and the colour value phase-match of display area, has realized reducing the colour of frame district and the contrast between the display area colour, makes visual effect relatively unified.

Referring to fig. 4, fig. 4 is a flowchart of another display screen border color control method according to an embodiment of the present invention, and the main difference between the method and the embodiment is that in the embodiment, color values of a display area are obtained according to whether a display panel is in an off-screen state or an on-screen state. As shown in fig. 4, the method comprises the steps of:
step 401, if the display panel is in a bright screen state, calculating a color value of a preset edge area of the display area;
if the display panel is in a bright screen state, the color value of the display area is determined by the displayed picture, and specifically, the color value can be obtained by analyzing the currently displayed picture through a Central Processing Unit (CPU) or a Graphic Processing Unit (GPU) of the mobile terminal. Since the color contrast between the frame area and the display area adjacent to the frame area is most obvious and most noticeable, in this embodiment, when the display panel is in a bright screen state, only the color value of the preset edge area of the display area is calculated.
In this embodiment, the preset edge area is an area extending a preset width from the junction of the display area and the frame area into the display area, and the preset width may be set according to specific conditions. If the size of the display area is large, for example, the diagonal size is 10 inches, the width of the preset edge area may be set to 1 cm, and if the diagonal size of the display area is 4 inches, the width of the preset edge area may be correspondingly reduced, for example, 3 mm, etc., obviously, the preset width value may also be adjusted according to the actual situation.
Step 402, if the display panel is in the screen-off state, taking a preset color value in the screen-off state as a color value of the display area.
If the display panel is in the off-screen state, the color value of the display area is the color of the display panel itself, and since the color is not the display color of the display panel, in this embodiment, the color value of the display panel in the off-screen state is preset and recorded, and if the display panel is in the off-screen state, the preset color value in the off-screen state may be used as the color value of the display area.
Since the display panel may include two states of off-screen and on-screen, in this embodiment, the color value of the display area is obtained through one of the above steps 401 and 402 according to the working state of the display panel.
And 403, determining a target temperature of the thermochromic layer according to the color value of the display area, wherein the color value of the thermochromic layer is matched with the color value of the display area at the target temperature.
After the color values corresponding to the display area are obtained according to the off-screen state and the on-screen state of the display panel, the target temperature of the temperature-sensitive color changing layer is further calculated according to the embodiment.
And 404, controlling the temperature of the temperature-sensitive color-changing layer to be the target temperature through the temperature control assembly.
In this embodiment, the temperature of the temperature-sensitive color-changing layer is further controlled by adjusting the operating power of the temperature control assembly, so as to control the color of the temperature-sensitive color-changing layer.
Optionally, the frame region includes N frame regions, the N frame regions are respectively adjacent to N preset edge regions of the display region, the thermochromic layer includes N thermochromic regions, the N thermochromic regions respectively correspond to the N frame regions, where N is an integer greater than or equal to 1;
the obtaining the color value of the display area comprises:
calculating the color mean value of N preset edge areas of the display area;
the step of determining the target temperature of the thermochromic layer according to the color value of the display area includes:
determining target color mean values of the N frame areas according to the color mean values of the N preset edge areas, wherein the target color mean value of each frame area is matched with the color mean value of the adjacent preset edge area;
determining the target temperatures of the N temperature sensing color-changing areas according to the target color mean values of the N frame areas, wherein the target temperature of each temperature sensing color-changing area corresponds to the target color mean value of the corresponding frame area;
the controlling the temperature of the temperature-sensitive color changing layer by the temperature control component to be the target temperature comprises:
and controlling the temperatures of the N temperature sensing color changing areas to be respectively corresponding target temperatures through the temperature control assembly.
Because images displayed by preset edge regions of the display panel may be different, in order to improve the control accuracy of the color border of the thermochromic layer, in this embodiment, optionally, the border region includes N border regions, the N border regions are respectively adjacent to the N preset edge regions of the display region, the thermochromic layer includes N thermochromic regions, the N thermochromic regions respectively correspond to the N border regions, where N is an integer greater than or equal to 1.
In this embodiment, the frame area may be divided into N frame areas. In one embodiment, for example, four frame regions are divided into four frame regions, i.e., up, down, left, and right, in yet another embodiment, the frame regions may be divided according to length, for example, the frame regions are divided into one frame region every 5 mm along the boundary between the display region and the frame regions. Correspondingly, according to the distribution of the frame area, the temperature-sensitive color-changing area is also divided into N temperature-sensitive color-changing areas corresponding to the frame area, and N preset edge areas corresponding to the frame area are also divided on the display area.
Further, step 401 may further include: and calculating the color mean value of the N preset edge areas of the display area.
In this embodiment, the color mean value of each preset edge region is calculated according to the divided preset edge regions. The color mean in this embodiment refers to representing the color value of each predetermined edge region by using the average value of the pixels included in the region, for example, if the pixels of two pixels are RGB (15,24,74) and RGB (17,40,36), the two pixels are added and the average color value RGB (16,32,55) is taken as the color mean of the two pixels. In this embodiment, the color mean of the preset edge region is calculated according to the divided preset edge region.
If the display panel is in a bright screen state, the method may further include the following steps:
determining target color mean values of the N frame areas according to the color mean values of the N preset edge areas, wherein the target color mean value of each frame area is matched with the color mean value of the adjacent preset edge area;
and determining the target temperatures of the N temperature sensing color-changing areas according to the target color mean values of the N frame areas, wherein the target temperature of each temperature sensing color-changing area corresponds to the target color mean value of the corresponding frame area.
In this embodiment, the target color mean value of the corresponding frame region is determined according to the color mean value of each preset edge region, and the target temperature of the corresponding temperature-sensitive color-changing region is further determined, so that the target temperature of each temperature-sensitive color-changing region can be specifically determined according to different display pictures.
Even if the display panel is in the off-screen state, the target temperatures of the N thermochromic regions can be determined through the two steps, but generally, the color values of the display regions in the off-screen state are the same, so that the target temperatures of the thermochromic regions are also the same. Obviously, if the color values of the display panel are not the same everywhere but have a certain difference in the screen-off state, the target temperatures of the N thermochromic regions can also be determined through the optional steps, so that the colors of the border regions can be controlled more accurately.
This step 404 may also include: and controlling the temperatures of the N temperature sensing color changing areas to be respectively corresponding target temperatures through the temperature control assembly.
In this embodiment, further control N temperature sensing discoloration areas as respective corresponding target temperatures through the temperature control assembly, after the temperature of each temperature sensing discoloration area reaches the target temperature, then its color also correspondingly changes to the color value as the target color value, can make the color of display area and the color phase-match of frame district.
In this embodiment, the heating temperature of the temperature control component can be controlled by controlling the power of the temperature control component, and specifically, for example, the power of the temperature control component can be adjusted by controlling the power supply current of the temperature control component.
For example, in one embodiment, when the temperature of the thermochromic layer needs to be maintained at the target temperature is calculated according to the heating efficiency of the temperature control assembly and the heat loss during heating, the operating current of the temperature control assembly is used to supply power to the temperature control assembly. In another embodiment, the power of the temperature control element may be controlled by measuring the temperature of the thermochromic layer, for example, if the temperature of the thermochromic layer is lower than the target temperature, the power of the temperature control element is increased by increasing the power supply current of the temperature control element, and if the temperature of the thermochromic layer is higher than the target temperature, the power supply current of the temperature control element is decreased.
In another specific embodiment, the initial color of the thermochromic layer in the unheated state may be further modulated to the color of the display panel in the screen-off state, so that in the screen-off state, heating may be avoided to save electric energy, and in the screen-on state, the temperature of the thermochromic layer may be further controlled by the temperature control assembly, so that the color of the frame region matches the color of the display region.
In this embodiment, various optional implementation manners are added on the basis of the embodiment shown in fig. 3, so that convenience and flexibility in controlling the color of the display screen frame can be further improved, the color of the display screen assembly frame area is matched with the color of the display area, and the overall visual effect is improved.
