< example >
The embodiment of the invention provides a display method of double display screens, which is used for a first display screen and a second display screen, wherein a gap with a preset size is arranged between the first display screen and the second display screen, and fig. 1 shows a flow chart of a network information acquisition method of the embodiment of the invention.
As shown in fig. 1, the method comprises the following steps:
first, in step S1100, a total horizontal component of the screen resolution is calculated, which corresponds to a sum of horizontal sizes of the first display screen, the second display screen, and the gap.
The screen resolution is a parameter for rendering an image by a computer, for example, the screen resolution is W1 × W2, then the horizontal component W1 of the screen resolution and the vertical component W2 of the screen resolution are used by the computer to render a corresponding image according to the screen resolution.
In this embodiment, taking VR equipment as an example, VR equipment includes: a host side and a Head Mounted Display (HMD) side. The host side transmits an image signal to the HMD side through a High-definition multimedia Interface (HDMI) so that an image is displayed on a display screen of the HMD side. The display screen on the HMD side comprises a first display screen and a second display screen, and a gap with a preset size is arranged between the first display screen and the second display screen.
Specifically, in the present embodiment, the display screens of different models of HMDs respectively correspond to respective model parameters, for example, fig. 2 shows a schematic diagram of a dual display screen according to an embodiment of the present invention, in which the horizontal dimensions of the display screen (including the first display screen and the second display screen) of a particular model of HMD are L1 and L2, the vertical dimension is H, the width of the gap between the first display screen and the second display screen is S, and the pixel density of this display screen in the horizontal direction is ρ.
The total horizontal component of the screen resolution corresponds to a sum of horizontal sizes of the first display screen, the second display screen and the gap, that is, since pixel densities of the first display screen and the second display screen in the horizontal direction are both ρ, the total horizontal component of the screen resolution corresponds to a sum of pixel numbers of the first display screen, the second display screen and the gap in the horizontal direction.
As an implementable way of obtaining the total horizontal component of the screen resolution:
firstly, respectively obtaining the number of pixels of the first display screen, the second display screen and the gap in the horizontal direction according to the horizontal size of the first display screen, the second display screen and the gap and the preset pixel density rho in the horizontal direction; namely, the number of pixels P1 in the horizontal direction of the first display panel and the second display panel is L1 ρ, P2 is L2 ρ, and the number of pixels P3 in the horizontal direction of the gap is S ρ.
Then, taking the sum of the first display screen, the second display screen and the number of pixels of the gap in the horizontal direction as the total horizontal component of the screen resolution; that is, the total horizontal component W3 of the screen resolution is P1+ P2+ P3 is L1 × ρ + L2 × ρ + S × ρ.
As another practicable way to obtain the total horizontal component of the screen resolution:
firstly, respectively obtaining the first display screen, the second display screen and the pixel number rho of the gap in the horizontal direction according to the total size L of the double display screens in the horizontal direction and the preset pixel density in the horizontal direction; namely, the total pixel number P in the horizontal direction of the dual display screen is L ρ.
Then, taking the total pixel number of the double display screens in the horizontal direction as the total horizontal component of the screen resolution; i.e., the total horizontal component W3P of the screen resolution.
After the total horizontal component of the screen resolution is calculated, the process proceeds to step S1200, and image rendering is performed according to the preset vertical component of the screen resolution and the total horizontal component, so as to obtain a rendered image.
In this embodiment, the vertical component of the screen resolution is set according to actual needs, for example, an arbitrary preset value W4, and the host renders according to the screen resolution with a value W3 × W4. Wherein the vertical component preset value W4 of the screen resolution is related to the dimension H of the display screen in the vertical direction and the preset pixel density of the display screen in the vertical direction. After acquiring the resolution W3 × W4, the host side performs calculation and rendering according to the resolution, and then outputs an image corresponding to the resolution W3 × W4 to the HMD side via HDMI, thereby obtaining a corresponding rendered image.
After the rendered image is obtained, step S1300 is performed, starting with the first side of the rendered image, and a first sub-image corresponding to the first display screen is intercepted from the rendered image, so that the first sub-image is displayed by the first display screen.
Or, after the rendered image is obtained, step S1400 is performed, and a second sub-image corresponding to the second display screen is intercepted from the rendered image starting from the second side of the rendered image, so that the second sub-image is displayed on the second display screen.
It should be noted that, the execution sequence of step S1300 and step S1400 is sequential, that is, step S1300 may be executed first and then step S1400 is executed, step S1400 may be executed first and then step S1300 is executed, or step S1300 and step S1400 may be executed simultaneously.
FIG. 3 shows a rendered image schematic of an embodiment of the invention. Referring to fig. 3:
specifically, the specific implementation of step S1300 may be: and intercepting the rendered image according to the number of pixels P1 of the first display screen in the horizontal direction by taking the first side of the rendered image as a start to obtain the first sub-image. And then, the first sub-image is displayed on the first display screen.
Specifically, the specific implementation of step S1400 may be: and intercepting the rendered image according to the pixel number P2 of the second display screen in the horizontal direction by taking the second side of the rendered image as a start to obtain the second sub-image. And then, the second sub-image is displayed on the second display screen.
Wherein the second side of the rendered image is opposite the first side of the rendered image.
For example, the interception processes in step S1300 and step S1400 may be implemented as follows: in this embodiment, the VR device bridge chip converts the HDMI signal into two Mobile Industry Processor Interface (MIPI) signals, and then respectively transmits the two MIPI signals to the first display screen and the second display screen for image display.
The bridge chip receives the rendered image data in a line-by-line mode, wherein each line of image data corresponds to a rendered image, and when the line of image data is split into two paths of MIPIs corresponding to the first display screen and the second display screen, the start and the end of each path of MIPI are appointed. For example, the bridge chip is configured to supply, to the MIPI corresponding to the first display screen, P1 ═ L1 ×. ρ pixels in the horizontal direction starting from the first side of the rendered image data, supply, to the MIPI corresponding to the second display screen, P2 ═ L2 ×. ρ pixels in the horizontal direction starting from the second side of the rendered image data, and discard the remaining P3 ═ S ×. ρ pixels in the horizontal direction. According to the above intercepting method, a first sub-image corresponding to a resolution of P1 × W4 starting from the first side of each frame of the rendered image is displayed on the first display screen, and a second sub-image corresponding to a resolution of P2 × W4 starting from the second side of each frame of the rendered image is displayed on the second display screen.
For further understanding, the pixel density of the display screen in the horizontal direction is P423 PPI, the sizes L1 of the first display screen and the second display screen in the horizontal direction are equal to L2, and the number of pixels occupied in the horizontal direction is 1080 (i.e. P1-P2-1080) in the case of the above pixel density; if the width of the gap between the first display panel and the second display panel is S (4/25.4) inches, the number of pixels occupied by the gap in the horizontal direction is 67 (i.e., P3 is 67); according to the display method provided in the present embodiment, the resolution width (i.e., the total horizontal component of the screen resolution) of the HMD-side overall HDMI display device information may be configured as P-W3-1080 × 2+ 67-2227, and since the preset vertical component of the screen resolution is W4-1200, that is, the screen resolution W3 × W4 is: 2227 × 1200.
After acquiring the screen resolution from the HDMI display device information, the host calculates and renders the screen resolution according to the screen resolution, and then outputs an image (i.e., rendered image) with W3 × W4 being 2227 × 1200 to the HMD side via HDMI. The bridge chip receives image data corresponding to the rendered image in a line-by-line manner, and can specify the start and end of each path of MIPI when the line of data is split into two paths of MIPIs. Through configuring, 1080 pixels on the left side of each row of data can be sent to the corresponding MIPI of left side display screen, 1080 pixels on the right side are sent to the corresponding MIPI of right side display screen, and 67 pixels in the middle are abandoned. With the dual panel display method of the present embodiment, the left P1 × W4-1080 × 1200 pixels of each frame are displayed on the left panel, the right P2 × W4-1080 × 1200 pixels are displayed on the right panel, and the middle P3 × W4-67 × 1200 pixels are discarded.
Alternatively, the sizes of the first display screen and the second display screen in the horizontal direction are equal to each other as L1 and L2, in which case the resolutions of the first sub-image and the second sub-image displayed to the first display screen and the second display screen are equal.
Optionally, after the rendered image is intercepted in steps S1300 and S1400, a third sub-image occupying P3 pixels in the horizontal direction remains, and the third sub-image is not used for displaying on the display screen, so that the third sub-image may be discarded.
Note that P, P1, P2, P3, W1, W2, W3, and W4 in the above embodiments represent the number of pixels, which are positive integers; l1, L2, S, L and H are positive numbers and can be in inches or millimeters, etc.; ρ is a positive number and may be in PPI units.
