Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only for explaining the present invention, is not intended to limit the present invention.
Please refer to Fig. 1, the present invention selects the better embodiment of rotary display to comprise that command receiver 10, user's rotational display pattern arrange module 12, rotational display mode register 14, axis signal acquisition device of mechanical rotation system 16, level angle register 18, level angle counter 20, one-level driver module 22, secondary driver module 24, one-level image scaling module 26, secondary image scaling module 28, one-level display buffer storer 30, secondary display buffer storer 31, show rectification module 32, planimetric coordinates modular converter 34 and screen 36.
This user's rotational display pattern arrange module 12 for the rotational display pattern of display is set and by the pattern storage arranging to rotational display mode register 14.Please refer to Fig. 2 A and Fig. 2 B, to be vertically shown as example, in present embodiment, provide two kinds of rotational display patterns: one, Zoom display, screen 36 rotate to arbitrarily angled after, keep complete vertical demonstration after whole picture convergent-divergent; Two, directly show, screen 36 rotate to arbitrarily angled after, keep whole picture size constant, vertically show a display frame and screen overlay part.No matter be Zoom display or directly demonstration, do not have the screen 36 of image section all not export, retain blank or blank screen.
This demonstration rectification module 32 is mainly used in, when the image generation convergent-divergent that will show or shift in position, suitably adjusting the position of whole picture disply, makes it show between two parties as far as possible.
First one-level driver module 22 obtains the resolution of screen, then receives the image information that will show, obtains the resolution of image, and 26 pairs of images of one-level image scaling module carry out convergent-divergent, and output in one-level display buffer storer 30.When user sends after rotate instruction, first command receiver 10 records screen 36 present level angles of inclination and stores this horizontal tilt angle into level angle register 18, then notify axis signal acquisition device of mechanical rotation system 16 to start rotation, when user stops the rotation, level angle counter 20 is according to the angle of axis signal acquisition device of mechanical rotation system 16 rotations, original angle in while read level angle register 18, calculate the horizontal tilt angle that screen 36 is new, and again write level angle register 18, then notify planimetric coordinates modular converter 34, planimetric coordinates modular converter 34 utilizes its inner angular transition function engine, the former coordinate of each pixel is carried out to coordinate conversion, and data are sent to secondary driver module 24, first secondary driver module 24 obtains current screen effective resolution and horizontal tilt angle-data, then read the rotational display pattern in rotational display mode register 14, and adjust accordingly according to rotational display pattern, finally by demonstration rectification module 32, picture pixel is adjusted to screen upright position placed in the middle, and output to secondary display buffer storer 31, and finally on screen 36, show.
When user is not rotated screen, planimetric coordinates modular converter 34, secondary driver module 24, secondary image scaling module 28, show that rectification module 32 all can be to the data-switching in one-level display buffer storer 30, but the data in one-level display buffer storer 30 are directly transferred to secondary display buffer storer 31.If screen rotation, 34 of planimetric coordinates modular converters are to the data-switching in one-level display buffer storer 30, again data transmission to secondary driver module 24, secondary driver module 24 is according to rotational display pattern, if direct display mode, directly data are delivered to demonstration rectification module 32 and correct, be then saved in secondary display buffer storer 31 and finally output to screen 36, if Zoom display pattern, secondary driver module 24 reads screen resolution and angle, calculate the vertical rectangle of current screen internal area maximum, and obtain its screen coordinate with and with the ratio of screen resolution, then secondary image scaling module 28 is carried out convergent-divergent by this ratio, obtain the resolution identical with this rectangle, and then the orthogonal coordinate of image pixel coordinate conversion after conversion, and output to and show rectification module 32, show after 32 pairs of general image alignings of rectification module, by secondary display buffer storer 31, finally outputing to screen 36 shows.
Please refer to Fig. 3, the better embodiment of the display packing of rotary display of the present invention comprises the following steps:
S1, user arrange rotational display pattern.
S2, one-level driver module 22 receive the image information that will show, and obtain screen resolution.
S3, one-level image scaling module 26, according to the ratio of screen resolution and image resolution ratio, are carried out convergent-divergent to image, and output in one-level display buffer storer 30.
S4, user send rotate command, record the data such as level angle of current location screen.
S5, axis signal acquisition device of mechanical rotation system 16 are done machinery rotation and are stopped the rotation according to user instruction.
S6, axis signal acquisition device of mechanical rotation system 16 stop rear notice level angle counter 20 and calculate postrotational horizontal tilt angle.
S7, level angle counter 20 are write into final horizontal tilt angle level angle register 18 and are notified planimetric coordinates modular converter 34.
S8, planimetric coordinates modular converter 34 be the horizontal tilt angle in each pixel coordinate of reading images read level angle register 18 from one-level display buffer storer 30, call its interior angle transfer function engine, according to horizontal tilt angle, the former coordinate of pixel is carried out being transported to secondary driver module 24 after angle coordinate conversion.
S9, secondary driver module 24 read current rotational display pattern and screen resolution.
S10, determine whether Zoom display pattern, if so, perform step S11; If not, perform step S13.
S11, read screen resolution, horizontal tilt angle, calculate the vertical rectangle of current screen internal area maximum, and obtain its resolution ratio.
S12, secondary image scaling module 28 are carried out convergent-divergent by this ratio, obtain the resolution identical with this rectangle, and then the orthogonal coordinate of image pixel coordinate conversion after conversion.
After S13,32 pairs of general image alignings of demonstration rectification module, view data is stored to secondary display buffer storer 31.
S14, each pixel of image is outputed to screen 36 by coordinate.
In above-mentioned steps, be while vertically showing required vertical rectangle be example, what if desired show is horizontal displaying contents, in step S11, calculates the horizontal rectangular of current screen internal area maximum, and obtains its resolution ratio.
Apply above-mentioned rotary display, screen can rotate freely, but it is visual vertical that displaying contents keeps, can meet the multiple demands of browsing such as film (horizontal screen), video and webpage (perpendicular screen) simultaneously, user can be according to interior architecture needs, display can be settled sidewards, also can endwaysly settle.And aforementioned display device provides secondary display buffer, raising display speed and display quality.
