Problems solved by technology

If you need to use two screens, you need to control the display of each screen separately, which will bring a greater workload to product development
[0003] In addition, projection technology has a long history, but due to various reasons, projection technology has not been applied to the field of handheld electronic device technology

Embodiment 1

[0049] see Figure 1 to Figure 3 , the present invention discloses a multi-screen projection display control system for handheld electronic devices, the system includes: two touch screens (namely the first touch screen 11, the second touch screen 12), a projection module 14, a projection module adjustment mechanism 15, a touch screen Sensing module 16 , gravity sensing mechanism 17 , splicing sensing module 18 , and display control module 19 . The handheld electronic device may be a mobile phone, a tablet computer and the like.

[0050] The first touch screen 11 and the second touch screen 12 have the same size and are respectively located on both sides of the electronic equipment body 13 (the first touch screen 11 and the second touch screen 12 can also be arranged on one side of the electronic equipment body 13, which are originally spliced ​​on together or can be spliced ​​together), the electronic device body 13 includes a first body 131 and a second body 132, the first t...

Embodiment 2

[0065] In this embodiment, the multi-screen projection display control system includes: multiple screens, a projection module, a sensing module, a projection module adjustment mechanism, and a display control module.

[0066] The difference from Embodiment 1 is that in this embodiment, the number of screens may be more than two, such as 3 or 4. Multiple screens can be spliced ​​together to form a larger spliced ​​screen; or, multiple screens originally form a larger screen.

Embodiment 3

[0068] The difference between this embodiment and Embodiment 1 is that in this embodiment, when a touch action is issued on one screen to control another screen (take the second screen controlling the first screen as an example), the control of the second screen The display function is turned off and only responds to the touch function; when the second screen generates a touch signal, the touch coordinates on the second screen are converted into the corresponding coordinates of the first screen through the mapping module, that is, the touch action is equivalent to the corresponding to the first screen location; if the first screen sleeps, the second screen goes to the same state.

[0069] In addition, when using the first screen and the second screen to touch together, the magnet sensing unit senses whether the first screen and the second screen are merged. When the first screen and the second screen are sensed to be merged into one screen, the touch sensing module is used to ...

Abstract

The invention discloses a multi-screen projection display control system and method of a handheld electronic device. The system comprises multiple screens, a projection module, a sensing module, a projection module adjusting mechanism and a display control module. The multiple screens can be spliced into a spliced screen; the projection module is used for projecting display pictures to the multiple screens respectively, or projecting the display pictures to one screen, or projecting the display pictures to the spliced screen formed by splicing of the multiple screens; the sensing module is used for sensing changes, including position changes and splicing and separation changes, of the screens in real time; the projection module adjusting mechanism is used for adjusting the position, projection angle and focal length of each projection unit in the projection module; the display control module is used for controlling actions of the projection module adjusting mechanism according to sensing of the sensing module so as to control actions of each projection unit in the projection module. Images can be displayed in the multiple display screens through a projection mode.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, and relates to a handheld electronic device, in particular to a multi-screen projection display control system of the handheld electronic device; meanwhile, the invention also relates to a multi-screen projection display control method of the handheld electronic device. Background technique [0002] At present, the display screens used in handheld devices all implement display by actively emitting light. If two screens need to be used, the display of each screen needs to be controlled separately, which will bring greater workload to product development. [0003] In addition, the projection technology has a long history, but due to various reasons, the projection technology has not been applied to the technical field of handheld electronic devices. [0004] In order to better realize the display of the two screens without controlling the screens separately and without the self-il...
