However, as will be understood by those skilled in the art, the present invention may be practiced without these specific details.
Example 1:
as shown in fig. 1 to 4b, the present embodiment provides an adjusting method for a display screen of virtual reality glasses, where the virtual reality glasses include a display structure and a convex lens 1, a display area 2 of the display structure is used for displaying the display screen, the convex lens 1 is capable of transmitting light emitted by the display structure, and the display screen is perpendicular to a main optical axis of the convex lens 1, and the adjusting method includes:
s11, the offset type and offset distance of the center 21 of the display area 2 with respect to the center 11 of the convex lens 1 are acquired.
In this case, that is, the display area 2 of the display device is generally used for displaying the display screen, so that when the relative positions of the center 21 of the display area 2 and the center 11 of the convex lens 1 are obtained, the relative positions of the center of the screen to be displayed and the center 11 of the convex lens 1 can be known.
S12, the display mode of the display screen is adjusted according to the offset type and the offset distance so that the center of the display screen corresponds to the center 11 of the convex lens 1.
In other words, by adjusting the position of the display screen in the display area 2, the center of the display screen can be finally matched to the center 11 of the convex lens 1.
The adjusting method of the display frame of the virtual reality glasses of the embodiment mainly adjusts the position of the display frame in the display area 2 by adjusting the display mode, so that the center of the final display frame corresponds to the center 11 of the convex lens 1. Compared with the relative position of the adjusting display device and the convex lens 1 in the prior art, the adjusting method of the embodiment can accurately and simply enable the center of the display picture to correspond to the center 11 of the convex lens 1 on the premise of not changing the structure of the virtual reality glasses, thereby ensuring the display effect of the virtual reality glasses and improving the user experience.
Example 2:
as shown in fig. 1 to 4b, the present embodiment provides an adjusting method for a display screen of virtual reality glasses, where the virtual reality glasses include a display structure and a convex lens 1, a display area 2 of the display structure is used for displaying the display screen, the convex lens 1 is capable of transmitting light emitted by the display structure, and the display screen is perpendicular to a main optical axis of the convex lens 1, and the adjusting method includes:
s21, the offset type and offset distance of the center 21 of the display area 2 with respect to the center 11 of the convex lens 1 are acquired.
In this case, that is, the display area 2 of the display device is generally used for displaying the display screen, so that when the relative positions of the center 21 of the display area 2 and the center 11 of the convex lens 1 are obtained, the relative positions of the center of the screen to be displayed and the center 11 of the convex lens 1 can be known.
Specifically, the display structure includes a plurality of pixels distributed in an array in the display area 2; acquiring the offset type and the offset distance of the center 21 of the display area 2 from the center 11 of the convex lens 1 includes:
s211, the projection of the center of the projection of the display area 2 on the specific plane and the projection of the center 11 of the convex lens 1 on the specific plane have an offset in the specific direction, the offset distance is a first distance a, the specific plane is a plane perpendicular to the main optical axis of the convex lens 1, and the specific direction is a direction parallel to the row direction or the column direction in which the pixels are located.
In other words, the present embodiment includes two types of offset: offset in a direction parallel to the row in which the pixels are located and offset in a direction parallel to the column in which the pixels are located.
S22, the display mode of the display screen is adjusted according to the offset type and the offset distance so that the center of the display screen corresponds to the center 11 of the convex lens 1.
In other words, by adjusting the position of the display screen in the display area 2, the center of the display screen can be finally matched to the center 11 of the convex lens 1.
Specifically, the adjusting the display mode of the display screen according to the offset type and the offset distance includes:
s221, the display screen is adjusted in a specific direction.
In this case, the display screen is adjusted in a direction parallel to the rows or columns of the pixels, so that the center of the display screen corresponds to the center 11 of the convex lens 1.
Further, if the specific direction is a direction parallel to the row of the pixels, the center of the projection of the display area 2 on the specific plane is closer to the projection of the first column of pixels on the specific plane than the projection of the center 11 of the convex lens 1 on the specific plane; adjusting the display in the particular direction includes: the display screen is moved a first distance a in a first direction, which is a direction parallel to the specific direction and pointing from the first column of pixels to the last column of pixels, as indicated by x in fig. 3 b.
Here, the pixel columns of the array are arranged from left to right, and the rows are arranged from top to bottom, which is equivalent to that on a specific plane, the center of the projection of the display area 2 is on the left of the projection of the center 11 of the convex lens 1, that is, the display area 2 is shifted to the left relative to the convex lens 1 (as shown in fig. 3 a), so that the center of the display image corresponds to the center 11 of the convex lens 1.
Specifically, moving the display screen by the first distance a in the first direction includes: inputting non-display signals to the pixels of the 1 st to nth columns so that the pixels of the 1 st to nth columns do not display a display picture, and sequentially inputting the display signals to the pixels of the n +1 st to last columns from the pixels of the n +1 th columns so that the pixels of the n +1 th to last columns display the display picture, wherein the size of a display area 2 formed by the pixels of the 1 st to nth columns in the row direction is the same as the size of the first distance a.
Here, the "non-display signal" may be a signal for causing the pixel to display 0 gray scale, for example, a voltage of 0V. That is, when the display screen is shifted to the left, the pixels in the 1 st to nth columns do not display the display screen, and the screen originally input to the pixels in the 1 st column is displayed from the pixels in the (n + 1) th column, so that the entire display screen is moved to the right.
For example, if the size of the first distance a is equal to the position of 3 pixels, the pixels in the 1 st to 3 rd rows are not displayed, the original display signal of the pixel in the 1 st row is input to the pixel in the 4 th row, and the original signal of the pixel in the third last row is input to the pixel in the last row, so that the display moves to the right until the display corresponds to the center 11 of the convex lens 1. In general, each pixel includes three subpixels, namely, red, green and blue, distributed in a row, so that a signal can be given based on the position of the subpixel.
If the display area 2 is shifted to the right, the specific display method may be adjusted as follows when the display area 2 is shifted to the right.
Further, if the specific direction is a direction parallel to the column in which the pixels are located, the center of the projection of the display area 2 on the specific plane is farther from the projection of the first row of pixels on the specific plane than the projection of the center 11 of the convex lens 1 on the specific plane; adjusting the display in the particular direction includes: the display screen is moved a first distance a in a second direction, which is a direction parallel to the particular direction and pointing from the last row of pixels to the first row of pixels, as indicated by y in fig. 4 b.
Here, the pixel columns of the array are arranged from left to right, and the rows are arranged from top to bottom, which is equivalent to that on a specific plane, the center of the projection of the display area 2 is below the projection of the center 11 of the convex lens 1, that is, the display area 2 is lower than the convex lens 1 (as shown in fig. 4 a), and it is necessary to move the display screen upward so that the center of the display screen corresponds to the center 11 of the convex lens 1.
Specifically, moving the display screen by the first distance a in the second direction includes: and storing and not outputting the display signals of the pixels of the 1 st row to the nth row, and sequentially inputting the display signals of the pixels of the (n + 1) th row into the pixels of the nth row before the pixels of the 1 st row to the last row so as to enable the pixels of the 1 st row to the nth row before the last row to display a display picture, wherein the size of a display area 2 which can be formed by the pixels of the 1 st row to the nth row in the column direction is the same as the size of the first distance a.
Here, "the display signal is stored and not output" corresponds to a case where the display signal is discarded. That is, when the display frame is shifted downward, the original display signals of the pixels in the 1 st to nth rows are not input into the pixels in the 1 st row, but the original display signals of the pixels in the (n + 1) th row are input into the pixels in the 1 st row, so that the pixels in the 1 st to nth last rows display the display frame; and no signal can be displayed for the pixels of the nth row to the last row so as to display 0 gray scale, thereby enabling the whole display picture to move upwards.
For example, if the size of the first distance a is equal to the position of 3 pixels, the pixels originally assigned to the 1 st row to the 3 rd row are discarded, the display signal to the pixels originally assigned to the 1 st row from the 4 th row is provided, and the display signal to the last row from the 3 rd row is provided, so that the frame moves upward until the frame is displayed corresponding to the center 11 of the convex lens 1.
If the display area 2 is shifted to the upper side, the specific display method may be adjusted according to the adjustment method for the display area 2 to the left side.
The adjusting method of the display frame of the virtual reality glasses of the embodiment mainly adjusts the position of the display frame in the display area 2 by adjusting the display mode, so that the center of the final display frame corresponds to the center 11 of the convex lens 1. Compared with the relative position of the adjusting display device and the convex lens 1 in the prior art, the adjusting method of the embodiment can accurately and simply enable the center of the display picture to correspond to the center 11 of the convex lens 1 on the premise of not changing the structure of the virtual reality glasses, thereby ensuring the display effect of the virtual reality glasses and improving the user experience.
Example 3:
as shown in fig. 1 to 6, the present embodiment provides an adjusting device for display frames of virtual reality glasses, the virtual reality glasses include a display structure and a convex lens 1, a display area 2 of the display structure is used for displaying the display frames, the convex lens 1 is capable of transmitting light emitted by the display structure, and the display frames are perpendicular to a main optical axis of the convex lens 1, the adjusting device includes:

and the data latch is connected with the processing unit and is used for outputting the display signal in the input register to the pixel or storing and not outputting the display signal in the input register through the information received by the processing unit.
Specifically, as shown in fig. 5, when the signal at the output terminal (CK) of the shift register is a high-level signal (CLKN ═ H), the display signal can be output to the corresponding pixel through the data latch; when the signal at the output terminal (CK) of the shift register is a low level signal (CKLN ═ L), the display signal inputted to the register is stored in the data latch, so that the data latch does not output a signal to the pixel, which corresponds to delayed display of the display screen. This method is suitable for the case where the display area 2 is left or up with respect to the convex lens 1.
In addition, when the obtaining module (located in the main board AP) sets the control terminal E of the processing unit to 1, the output terminal of the processing unit is in a high-impedance state (that is, the output terminal of the processing unit is disconnected from the input terminal of the data latch), and at this time, even if the output terminal (the register Q terminal) stored in the register normally outputs display data, the output terminal (the data latch Q terminal) of the data latch does not output a signal, that is, when the display area 2 is shifted to the right or to the lower side relative to the convex lens 1, the processing of the display information of the pixels in the first n columns or the first n rows is realized; when the obtaining module (located in the main board AP) sets the control terminal E of the processing unit to 0, the output terminal of the processing unit is in a non-high impedance state (that is, the output terminal of the processing unit is normally connected to the input terminal of the data latch), that is, when the display area 2 is shifted to the right or to the lower side with respect to the convex lens 1, the display information of the pixel after the (n + 1) th column or the (n + 1) th row is output.
