The invention relates to a multi-screen splicing method, a multi-screen splicing device and a multi-projection splicing large screen. The method comprises the following steps of observing a multi-screen model according to an analog camera arranged on an observation position, observing to acquire a proportion of the size of each screen of a multi-screen image, segmenting a received main frame imageaccording to the observed proportion of the size of each screen to acquire a sub-picture corresponding to each screen, stretching the sub-picture according to an actual resolution ratio of each screen on an observation site to acquire a sub-image actually displayed on each screen, and separately displaying the sub-image on each screen. According to the multi-screen splicing method, the scheme operation process is simple and efficient, and the quick splicing and displaying effect of the multiple screens can be achieved.

An embodiment of the invention discloses a switching control method of a desktop container and a terminal. The switching control method of the desktop container and the terminal are used for substituting for traditional moving component operation on an intelligent terminal based on touch operation. The method in the embodiment includes: enabling the terminal to acquire action judgment information when a component-based moving event is activated; enabling the terminal to recognize the action state according to the action judgment information; and enabling the terminal to switch a currently displayed page of the desktop container according to the action state and move a based component in the moving event to a switched page of the desktop container. By the aid of the scheme, hand fatigue of users, particularly users getting used to operating a large-screen terminal by one hand due to long press and dragging of the component can be relieved, and risks for dropping of the terminal are reduced, so that operating experience of the users can be improved.

The present invention is suitable for the computer technology field, and provides an operation method and system of a touch screen mobile phone. The method comprises when sensing a touch control signal on a touch sensitive line, obtaining a motion locus of the touch control signal, the touch sensitive line being arranged at a frame of the touch screen mobile phone; and moving the current page relative to the motion locus of the touch control signal according to the motion locus of the touch control signal. Through arranging the touch sensitive line on the frame of the touch screen mobile phone, the touch control signal sent by a user is monitored, the page on the touch screen mobile phone is moved according to the obtained motion locus of the touch control signal, the operation area at the bottom or the top of the touch screen mobile phone can be triggered in an operation capability range of a thumb of a single hand, man-machine interactivity is enhanced without reducing the display range of the screen, and experience feeling of single hand operation of the large screen mobile phone is improved.

In a light emitting display apparatus requiring power supply lines, excellent uniformity in display luminance is provided over a relatively large screen by disposing at least one of input terminals for the power supply lines between input terminals for signal lines.

The invention provides a prefabricated building sealing waterproof intelligent teaching practical training device which is used for prefabricated building sealing waterproof teaching practical training. Cognitive learning of a splicing seam structure, a wall sealing principle and structure waterproofing and material waterproofing intelligent teaching practical training under an informatization condition are satisfied. A real training environment for sealing is created, a waterproof construction outer layer of the wallboard is wrapped with a stainless steel plate, four walls are spliced to form a rectangle and slide to be opened and closed under the driving of an electric guide rail along the diagonals of the rectangle by taking intersection points of the diagonals as starting and ending points, and the splicing seams of the walls are fully displayed; practical trainees can carry out wall body splicing seam construction, sealing principle learning and gluing seam sealing technology repeated practical operation training. An informatization technology is applied to construct a three-dimensional virtual scene of a sealed waterproof construction environment, the three-dimensional virtual scene is presented on a large screen to synchronously demonstrate the sealed waterproof construction operation process of the fabricated building in real time, and the practical training process of practical training students is objectively evaluated and a record report is generated.
