As shown in fig. 2, in a first embodiment of the present application, a method for adjusting display parameters of a liquid crystal panel of the present application includes the following steps:
step S210: and acquiring the relative angle between a user and the liquid crystal panel in the space where the liquid crystal panel is located.
In this embodiment, the relative angle is an included angle between a line connecting center points of the user and the liquid crystal panel and a straight line of a plane where the liquid crystal panel is located, the top of the liquid crystal panel is provided with the collecting device, and when the user watches a picture displayed by the liquid crystal panel at a certain position, the relative angle between the user and the liquid crystal panel in a space where the liquid crystal panel is located is collected through the collecting device. The acquisition device comprises a camera and at least two signal sensors, the camera is used for detecting whether a user has a behavior of watching a picture displayed by the liquid crystal panel, and the behavior of detecting whether the user has the behavior of watching the picture displayed by the liquid crystal panel can be realized through image recognition. The signal sensor may emit and receive infrared signals or ultrasonic signals for detecting a relative distance between the user and the signal sensor. When the liquid crystal panel detects that a user watches a picture displayed by the liquid crystal panel at a certain position through the camera, the liquid crystal panel obtains the relative distance between the user and the signal sensor at the certain position through the signal sensor, and calculates the relative angle between the user and the liquid crystal panel in the space where the liquid crystal panel is located according to the relative distance.
Step S220: and acquiring target display parameters according to the relative angle.
In this embodiment, the display parameter of the liquid crystal panel may include at least one of a gamma voltage and a white balance parameter, wherein adjusting the gamma voltage may change the brightness of the liquid crystal panel, and the white balance parameter refers to color values of three primary optical colors of red, green and blue (RGB), such as RGB (240, 255, 125); the ratio of red, green and blue color values can be changed by adjusting the white balance parameters, so that the chromaticity of the liquid crystal panel is changed.
Specifically, after the relative angle between the user and the liquid crystal panel in the space where the liquid crystal panel is located is acquired, according to the relative angle, the target display parameter corresponding to the relative angle is acquired through the mapping relation between the relative angle and the target display parameter, or the target display parameter to be acquired is calculated through the relative angle, and the target display parameter is acquired according to the calculation result, and the like. The target display parameters are parameters which need to be operated when the liquid crystal panel works under a relative angle, for example, the relative angle is 30 degrees, the target display parameters are A0, and then the liquid crystal panel needs to display a picture according to A0; the target display parameters include at least one of a target gamma voltage and a target white balance parameter, and the liquid crystal panel can improve the color shift of the liquid crystal panel when working according to the target display parameters.
The color cast is the difference between the brightness and the chromaticity after the contrast between the current displayed picture of the liquid crystal panel and the picture displayed by the liquid crystal panel when the user watches the liquid crystal panel at the current position and the picture displayed by the liquid crystal panel when the user watches the liquid crystal panel just opposite to the central point of the liquid crystal panel. The larger the relative angle between the user and the liquid crystal panel in the space where the liquid crystal panel is located is, the smaller the degree of color cast of the liquid crystal panel is, and the smaller the acquired target display parameter is; the smaller the relative angle between the user and the liquid crystal panel in the space where the liquid crystal panel is located is, the larger the degree of color cast of the liquid crystal panel is, the larger the acquired target display parameter is. If the relative angle increases along the same direction, the acquired target display parameter is larger than the current display parameter of the liquid crystal panel, and if the relative angle decreases along the same direction, the acquired target display parameter is smaller than the current display parameter of the liquid crystal panel.
Step S230: and adjusting the current display parameters of the liquid crystal panel according to the target display parameters.
The liquid crystal panel obtains current display parameters of the liquid crystal panel under the relative angle, wherein the current display parameters comprise at least one of current gamma voltage and current white balance parameters. And increasing or decreasing the current display parameter according to the acquired target display parameter, changing the current display parameter into the target display parameter after the current display parameter is adjusted, and displaying the picture by the liquid crystal panel according to the target display parameter at the relative angle. When the current display parameters of the liquid crystal panel are adjusted according to the target display parameters, the current gamma voltage can be increased or decreased unilaterally to be the target gamma voltage, or the current white balance parameters can be increased or decreased unilaterally to be the target white balance parameters, or the current gamma voltage can be increased or decreased to be the target gamma voltage, and the current white balance parameters can be increased or decreased to be the target white balance parameters.
According to the technical scheme, the relative angle between the user and the liquid crystal panel in the space where the liquid crystal panel is located is collected, the target display parameter is obtained according to the relative angle, the current display parameter of the liquid crystal panel is adjusted according to the target display parameter, the brightness and the chromaticity of the liquid crystal panel are optimized by adjusting the display parameter of the liquid crystal panel, the color cast problem of the liquid crystal panel is improved, and the watching experience of the user is improved.
As shown in fig. 3, in the second embodiment of the present application, based on the first embodiment, the step S210 includes the following steps:
step S211: and acquiring the viewing angle of the liquid crystal panel viewed by the user.
In this embodiment, as shown in fig. 4, the viewing angle is a first included angle between a line connecting center points of the user and the liquid crystal panel and a straight line perpendicular to a plane where the liquid crystal panel is located, that is, an included angle θ in fig. 4, where MN represents a straight line perpendicular to the plane where the liquid crystal panel is located. In step S211, the step of obtaining the viewing angle of the user viewing the liquid crystal panel specifically includes:
step a: the method comprises the steps of transmitting a reference signal to a user through at least two signal sensors, and receiving a reflected signal of the reference signal through the signal sensors.
The acquisition device in the embodiment may include one camera and two signal sensors, each of which may transmit a reference signal and receive a reflected signal of the reference signal, where the reference signal includes an infrared signal or an ultrasonic signal. The route through which the signal sensor sends the reference signal is the same as the route through which the signal sensor receives the reflected signal of the reference signal, namely, the transmission route of the reference signal and the receiving route of the reflected signal are overlapped.
As shown in fig. 5, S0 in fig. 5 indicates a user, S1 and S2 indicate signal sensors, S3 indicates a camera, and the camera and the two signal sensors are both disposed on the top of the liquid crystal panel, preferably at the middle position of the top of the liquid crystal panel, and may be disposed at other positions on the top of the liquid crystal panel, which is not limited in this embodiment. Wherein, have the interval between two signal sensor, and the interval can preset, and the camera sets up in two signal sensor's centre. When the liquid crystal panel detects that a user watches a picture displayed by the liquid crystal panel at a certain position through the camera, the liquid crystal panel transmits a reference signal to the user through the two signal sensors, and receives a reflection signal of the reference signal transmitted by the liquid crystal panel through each signal sensor. For example, S1 transmits the reference signal S10, S1 receives the reflected signal S11 of S10, S2 transmits the reference signal S20, and S2 receives the reflected signal S21 of S20.
Step b: and determining the transmission distance of the reference signal of each signal sensor according to the emission time of the reference signal of each signal sensor and the receiving time of the reflected signal.
As shown in fig. 5, BA denotes the distance of the transmission route of the reference signal transmitted by S1, AB denotes the distance of the reception route of the reflected signal received by S1, and CA denotes the distance of the transmission route of the reference signal transmitted by S2, and AC denotes the distance of the reception route of the reflected signal received by S2, then the transmission distance of the reference signal of each signal sensor, i.e., BA + AB and CA + AC, can be calculated according to the following equations (1) and (2).
(T12-T11)v＝BA+AB (1)；
(T22-T21)v＝CA+AC (2)；
Where T11 denotes the transmission time of the S1 for transmitting the reference signal, T12 denotes the reception time of the S1 for receiving the reflected signal, T21 denotes the transmission time of the S2 for transmitting the reference signal, T22 denotes the reception time of the S2 for receiving the reflected signal, and v denotes the transmission speed of the reference signal (the transmission speed of the infrared signal or the ultrasonic signal in the air is known data).
Step c: determining the viewing angle according to the transmission distance of each of the signal sensors and a distance between the signal sensors.
Since the transmission route of the reference signal and the receiving route of the reflected signal coincide, BA, AB, CA, and AC are calculated from the transmission distance of the reference signal of each signal sensor. Then, a triangle is constructed according to S0, S1 and S2, namely the triangle ABC in FIG. 5, since the distance between the two signal sensors is preset, namely BC is known data; calculating the distance between the midpoint of the BC side and S0, namely the distance between S3 and S0, namely AO is the center line of BC according to the triangle center line length formula (Apollonius theorem formula), and particularly according to the formula
And calculating to obtain AO. Furthermore, a perpendicular line L is formed based on a central point connecting line of the liquid crystal panel, and the perpendicular line L is connected with the liquid crystal panelThe vertical line L is translated in the space where the liquid crystal panel is located, so that the vertical line L is perpendicular to the vertical line BC, and the included angle α is the viewing angle. Specifically, the included angle α may be calculated according to a complementary angle of α 0AOB (included angle β) of the triangular AOB, or calculated according to a difference between α 2AOC of the triangular AOC and a right angle. For example, in a triangular AOB, a cosine value of an angle AOB is calculated by a formula (4), according to the cosine value of the angle AOB, the cosine value of the angle AOB is subjected to inverse cosine calculation to obtain the angle AOB, and an included angle alpha 1 is the cosine angle of the angle AOB, namely alpha is 90-angle AOB;
step S212: and determining the relative angle according to the difference value between the viewing angle and a preset reference angle.
In this embodiment, the preset reference angle is a second included angle between a line connecting a center point of the user and the liquid crystal panel and a straight line of a plane where the liquid crystal panel is located when the user views the liquid crystal panel directly at the center point of the liquid crystal panel, that is, an included angle γ in fig. 4, where the included angle γ may be set to 90 ° or other values, the present embodiment is not limited, and a difference between the included angle γ and the included angle θ is the relative angle.
According to the technical scheme, the method and the device have the advantages that the viewing angle of the liquid crystal panel viewed by the user is obtained, and the relative angle is determined according to the difference value between the viewing angle and the preset reference angle, so that the accuracy of determining the relative angle between the user and the liquid crystal panel is realized.
As shown in fig. 6, in the third embodiment of the present application, based on the first embodiment, the step S220 includes the steps of:
step S221: and when one relative angle exists, acquiring a mapping relation between a pre-established display parameter and the relative angle.
In this embodiment, when it is detected that a user has a behavior of viewing a picture displayed by the liquid crystal panel, a relative angle between the user and the liquid crystal panel in a space where the liquid crystal panel is located is collected, and at this time, only one relative angle is obtained, and then a mapping relationship between a display parameter and the relative angle which is established in advance is obtained. The target display parameters corresponding to different relative angles can be found through the mapping relation between the display parameters and the relative angles, and the mapping relation between the display parameters and the relative angles is shown in table 1.
TABLE 1
Step S222: and acquiring the target display parameters according to the relative angle and the mapping relation.
