Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived from the embodiments of the present invention by a person skilled in the art without any creative effort, should be included in the protection scope of the present invention.
The invention discloses a method for touch control of the size and position of a sub-picture of display equipment in a PIP mode, wherein a connection structure of a signal source and the display equipment is shown in figures 2 and 3, two different signal sources are connected with a display main control chip of the display equipment through a connection interface, and the display main control chip is connected with a touch screen main control chip; in fig. 2, two computer devices are simultaneously used to connect with a display device, a main picture and a sub-picture are respectively displayed on the display device, and the size change and the position movement of the sub-picture are realized through a touch screen main control chip. In fig. 3, only one computer is used, and two different display signals are simultaneously turned on by one computer to access the display device, for example, when the main screen is a text document, a sub-screen player is disposed above the main screen; the size change and the position movement of the sub-picture are realized through the touch screen main control chip.
In fig. 2 and 3, PIP denotes a picture-in-picture. Generally, a display only displays one frame, and a display supporting pip can support two frames, a main frame and a sub-frame, to be displayed simultaneously. The PIP subpicture is superimposed on the main picture.
Touch panel represents a Touch screen, and like a mobile phone, a display also uses the Touch screen;
touch IC represents a Touch screen main control chip, and when touching the screen, the chip informs the display main control chip of the coordinates of the point touching the screen, for example: the left-most to right-most coordinates of the Touch panel currently used are from 0 to 4094, and the top-most to bottom-most coordinates are also from 0 to 4094. when touching the middle of the screen, the chip tells the display that the touched coordinates are (2047); (the resolution of the touch pad is greater than that of the screen, the higher the resolution of the touch pad is, the higher the touch accuracy is, and because the resolution of the touch pad is greater and the resolution of the display screen is small, the subsequent coordinate judgment and conversion can be carried out to judge whether the touch point occurs on a menu bar.)
Touch represents a Touch screen, and the Touch IC of the Touch screen returns the coordinates of single-point or multi-point Touch and sliding.
RTD2797 indicates the type of the display main control chip, and has functions of supporting multi-screen display, displaying OSD, and setting OSD and sub-screen positions.
The OSD represents a control menu for adjusting the display functions that the display main control chip supports.
As shown in fig. 1, the specific operation steps of the present invention are:
s1, connecting two signal sources on a display device with PIP function and setting the display pictures of the two signal sources as main pictures and sub-pictures respectively; the display device is provided with a touch screen main control chip and a display main control chip; the model of the touch screen main control chip is SW 4101C; the model of the display main control chip is RTD 2797;
s2, setting a toolbar on the display device and setting the toolbar at the edge of the sub-picture;
s3, detecting whether a touch condition exists on the display screen of the display equipment through a touch screen main control chip on the display equipment; when the touch screen main control chip detects that no touch condition exists on the display screen of the display device, the switching operation is not carried out; when the touch screen main control chip detects that a touch condition exists on the display screen of the display device, carrying out the next operation; each loop of the program reads the coordinate returned by the touch IC and judges whether the user has touch action; if the user touches the touch screen, the next operation is carried out;
s4, detecting the coordinates of a touch point on the display screen through a touch screen main control chip on the display device, and transmitting the coordinates of the touch point to a display main control chip in the display device;
s5, after receiving the touch point coordinate, the display main control chip judges the display area to which the touch point coordinate belongs; when the display area to which the touch point coordinate belongs is in the main picture, no operation is performed; when the display area to which the touch point coordinate belongs is in the toolbar, unlocking the locking state of the sub-picture, and controlling the edge size and the moving position of the sub-picture through a functional module in the toolbar; when the display area to which the touch point coordinate belongs is in the sub-picture, performing the next operation;
s6, judging whether the sub-picture is in a locked state through the display main control chip; when the sub-picture is in a locked state, no operation is performed; when the sub-picture is in the unlocking state, the edge size and the moving position of the sub-picture are controlled through the touch action of the sub-picture.
As shown in fig. 4, the step of determining the display area to which the touch point coordinate belongs by the display main control chip includes the following steps:
(1) setting Touch coordinate ranges of a Display as Touch _ X and Touch _ Y, wherein the corresponding ranges are (0-4094), and setting Display ranges of the Display as Display _ X and Display _ Y, wherein the ranges are Display _ X (0-3840) and Display _ Y (0-2160);
(2) it follows from the above assumptions that the ratio of touch and display ranges is X _ ratio 4094/3840 ═ 1.066, V _ ratio 4094/2160 ═ 1.895;
(3) setting the main picture as Source1 and the Sub picture as Source2, and setting the width and height of the Source2 picture in the display range as Sub _ H and Sub _ V; the diagonal points of the Source2 picture are A, B respectively, and the position A display is known and adjustable and is set as Sub _ X and Sub _ Y which are also within the display range;
(4) it can be derived that the display range of the source2 is a rectangular range from A to B, and the positions are A (SubX, SubY), B (SubX + SubH, SubY + SubV), respectively;
(5) coordinates of the corresponding A, B point mapped on the Touch screen are A _ Touch (Sub _ X _ ratio, Sub _ Y _ V _ ratio), B _ Touch ((Sub _ X + Sub _ H) X _ ratio, (Sub _ Y + Sub _ V) V _ ratio);
(6) the range of the toolbar OSD mapped on the Touch screen is a rectangular range formed by D and B, and coordinates are D (Sub _ X × X _ ratio, (Sub _ Y + Sub _ V + OSD _ H) × V _ ratio), B _ Touch ((Sub _ X + Sub _ H) × ratio, (Sub _ Y + Sub _ V): V _ ratio);
(7) in the same way, the touch screen range coordinates of the functional modules Move/Min/Max of the toolbar OSD can be obtained.
(8) When the touch screen is touched, the touch point coordinate is returned to the display main control chip by the touch IC; if the coordinates of the Touch point are in the rectangular ranges of the A _ Touch and the B _ Touch, the Touch is indicated to be in the source source2 range, if the coordinates of the Touch point are in the rectangular ranges of the B _ Touch and the D point, the Touch is indicated to be in the tool bar OSD range, otherwise, the Touch is indicated to be out of the source2 (namely, in the source1 range);
the touch action of the sub-picture comprises a click sub-picture edge adjusting action which can adjust the size of the sub-picture, a click sub-picture sliding action which can control the sub-picture to move and a double-finger gesture zooming action which can control the sub-picture to zoom.
When a touch occurs in Source2 and then drags, the sprite moves accordingly.
The position of the sub-picture movement can be back-calculated according to the proportion between the display coordinates and the touch coordinates.
The touch coordinate touch chip can be sent to the display main control chip when the sub-picture moves, the display main control chip can obtain the end point coordinate of the final position when the sub-picture moves, the display main control chip divides the coordinate by the X _ rate and the Y _ rate respectively to obtain the end point coordinate mapped on the display, and the display main control chip moves the position of the source2 to the end point coordinate. For example, Touch _ X and Touch _ Y are both shifted by 100, the corresponding frame shift Display _ X is 100/1.066 and about 94, and Display _ Y is shifted by 100/1.895 and about 53.
When the touch occurs in the vicinity of the positions of the points A and C in the Source2, the equal scaling of the Source2 picture can be realized.
The zooming operation of the sub-picture can also be realized by the double-finger gesture occurring in the Source 2;
the function modules in the toolbar include a moving sprite module move which can control the sprite to move, a minimized sprite module Min which can minimize the sprite, and a maximized sprite module Max which can maximize the sprite.
Holding down the move drag may effect movement of the sprite consistent with the effect of the drag within touch Source 2.
The sprite is minimized when Min is clicked.
The sprite is maximized when Max is clicked.
Of course, other shortcut methods for moving and zooming can be added on the toolbar OSD, so that the operations of zooming and moving the sub-picture are faster and more convenient.
When people use the computer and the mobile phone to display two pictures on the display equipment, the display picture of the computer can be set as a main picture, and the display picture of the mobile phone is set as a sub-picture; when a user processes computer information, the picture displayed by the mobile phone can be reduced in an equal ratio or moved to a position on the display screen without influencing the use of the computer; when a user processes the mobile phone information, the picture displayed by the mobile phone can be amplified in an equal ratio or moved to the position on the display screen where the user processes the information; the method is simple and quick to operate, effectively avoids the situation that the sub-picture and the main picture are mutually influenced, and improves the using effect of multi-picture browsing operation.
