Problems solved by technology

However, when the actual user uses the device, the fixed resolution may bring inconvenience to the use. For example, the user uses a handheld electronic device with a resolution of 320x240, and the user uses a resolution of 320x240 when watching a movie. Use 240x320 resolution when viewing e-books, so the resolution is more suitable for human reading habits
[0003] Handheld electronic devices that support rotating display screens on the market use built-in display chips to support display screen rotation, but they require a separate built-in chip, which is expensive and has poor versatility

Embodiment Construction

[0024] see figure 1 , the system for rotating the display screen is suitable for handheld electronic equipment, which includes a graphic device interface 11 , a control unit 12 and an input unit 13 . The graphics device interface 11 includes a plurality of graphics functions 112. These graphics functions are used to process graphics objects. The graphics objects are displayed on the display panel 14 through physical coordinates 111. The graphics functions 112 include physical coordinates and logical coordinate systems. The physical coordinates 111 are located at the physical coordinates. tie up. The control unit 12 is used to execute the application program. The application program converts the physical coordinates 111 into logical coordinates 121 according to the rotation instruction to rotate the graphic object. The logical coordinates 121 are located on the logical coordinate system, wherein the application program calculates the physical coordinates 111 and the logical coo...

Abstract

The invention relates to a system and a method for rotating a display picture. The system comprises a graphical device interface, a control unit and an input unit, wherein the graphical device interface comprises a plurality of graphical functions which are used for processing graph objects, and the graph objects are displayed on a display panel through physical coordinates; the control unit is used for executing an application program, and the application program converts the physical coordinates into logical coordinates according to rotation instructions so as to rotate the graph objects; the input unit is used for inputting the rotation instructions, and the input unit is accessed to the control unit which is accessed to the graphical device interface. The invention causes a user to freely rotate the displayed graph objects on the display panel according to the demands, and is convenient and fast.

Description

technical field [0001] The invention relates to a system and a method for rotating a display screen, in particular to a system and a method for rotating a handheld electronic device to display a screen. Background technique [0002] At present, the display direction of the display screen of the handheld electronic device is determined by the display panel, for example: LCD screen, once the hardware type is selected, the display direction and resolution of the handheld device are basically fixed, and future applications can only be Based on this resolution. However, when the actual user uses the device, the fixed resolution may bring inconvenience to the use. For example, the user uses a handheld electronic device with a resolution of 320x240, and the user uses a resolution of 320x240 when watching a movie. Use 240x320 resolution when viewing e-books, so the resolution is more suitable for human reading habits. [0003] Handheld electronic devices on the market that support...
