## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to on screen display (OSD), and more particularly to a display interface and display method for OSD.
2. Description of the Related Art
Display of on screen display (OSD) of current computer devices (for example, notebook (NB) or liquid crystal display (LCD)) is two-dimensionally represented with respect to adjustment of brightness or volume or switch of hardware functions such as wireless LAN and sunlight readable, as shown in FIGS. 1A ̃1C.
Generally, when a display interface of the OSD is activated, icons and wording are simultaneously displayed, even displaying the wording or a bar merely, as shown in FIGS. 1A ̃1C. With respect to development of computer devices, the display interface of the OSD cannot satisfy user requirements, so a 2.5 dimensional/3 dimensional (2.5D/3D) display interface of the OSD is designed to enhance added value and refinement.
However, the 2.5D/3D pattern design only considers display effect with a colorful background that other effects may not be observed under a white background, resulting in inconvenience of reading.
Thus, a display interface and display method for OSD is desirable.

Display methods for on screen display are provided. An exemplary embodiment of a display method for on screen display comprises the following. Radiative transition effect is provided for a display interface capable of an on screen display (OSD), wherein the radiative transition effect comprises scroll-in effect and scroll-out effect. It is determined whether the OSD is activated. A full-color pattern corresponding to the OSD is displayed when the OSD is activated. A layer with a black and transparent background is rendered and the scroll-in effect is displayed. It is determined whether the OSD is switched to off. It is determined whether display of the full-color pattern reaches a predetermined time if the OSD is not switched to off. The layer with the black and transparent background is rendered and the scroll-out effect is displayed if the OSD is switched to off.
Display interfaces are provided. An exemplary embodiment of a display interface comprises a pattern and a layer with a black and transparent background.

DETAILED DESCRIPTION OF THE INVENTION
Several exemplary embodiments of the invention are described with reference to FIGS. 2A through 4, which generally relate to a display interface and display method for OSD. It is to be understood that the following disclosure provides various different embodiments as examples for implementing different features of the invention. Specific examples of components and arrangements are described in the following to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. In addition, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various described embodiments and/or configurations.
The invention discloses a display interface and display method for OSD.
An embodiment of a display interface for OSD introduces more beautiful 2.5D/3D icons to enhance brand value and quality of the display interface for OSD (as shown in FIGS. 2A and 2B) that applies radiative transition effect (halation scroll-in, for example) to enhance representative effect of the display interface for OSD (as shown in FIGS. 3A and 3B). Thus, added value and refinement of a computer product can be enhanced to solve the problem that the display interface for OSD is interfered when different desktops are represented.
An embodiment of the invention first applies the radiative transition effect to different functions of the OSD, comprising switch of networks (such as WiMAX, Bluetooth, or infrared rays), use of touchpad, adjustment of brightness, and so on, and further comprising enabled/disabled (ON/OFF) of a sunlight readable mode (as shown in FIG. 3A), a volume plus/minus mode (as shown in FIG. 3B), and a display switch mode (as shown in FIG. 3C).
When the sunlight readable mode is enabled (ON), a full-color sunlight readable pattern is displayed with applied for the radiative transition effect while the full-color sunlight readable pattern is converted a gray-level pattern when the sunlight readable mode is disabled (OFF). When the volume is increased or decreased, a full-color volume pattern is displayed with applied for the radiative transition effect. When the display mode is switched, a full-color display pattern is displayed with applied for the radiative transition effect.
It is noted the radiative transition effect comprises scroll-in effect and scroll-out effect. The scroll-in effect represents radiative rays with a clockwise or anticlockwise direction while the scroll-out effect represents radiative rays with a direction opposite to that for the scroll-in effect. Additionally, partial functions of the OSD provide an enabled/disabled (ON/$OFF) modes, such as the sunlight readable mode, the display switch (comprising LCD, LCD+VGA, and VGA), the network switch (comprising WiMAX, Bluetooth, or infrared rays), the use of the touchpad, and so on. Partial functions of the OSD only provide an enabled (ON) mode, such as adjustment of the volume and brightness, and so on.
Display rules for the display interface for the OSD are described in the following.
When one of the OSD mode is enabled, a full-color pattern corresponding to the OSD mode is displayed while the pattern is converted to a gray-level pattern if the OSD mode is disabled. Regardless of the OSD mode is enabled or disabled, the displayed pattern is faded when display time thereof reaches a predetermined time (3 seconds, for example).
When the scroll-in effect of the radiative transition effect is generated, a pattern corresponding to an OSD mode is assigned halation scroll-in effect regardless of the OSD mode is enabled or disabled. As shown in FIGS. 3A and 3B, for example, when sunlight readable mode or the volume plus/minus mode is enabled, a pattern corresponding thereto is displayed and the halation scroll-in effect is assigned thereto.
When the scroll-out effect of the radiative transition effect is generated, a pattern switched to on is assigned the scroll-out effect while a pattern switched to off is not assigned the scroll-out effect but is only assigned gray out effect. As shown in FIG. 3, for example, when the display is switched from the “LCD” mode to the “LCD+VGA” mode, a pattern for the “LCD+VGA” mode is assigned the halation scroll-in effect while a pattern for the “LCD” mode is assigned gray out effect.
Since the halation is displayed as the while color, a layer with a black and 50% transparent background is rendered before the radiative transition effect is generated to enhance the radiative effect, such that the radiative transition effect can be seen even if the background of the desktop of a computer device is represented as white color.
FIG. 4 is a flowchart of a display method for OS of the present invention.
Radiative transition effect is provided for a display interface capable of an on screen display (OSD) (step S401), wherein the radiative transition effect comprises scroll-in effect and scroll-out effect. It is determined whether the OSD is activated (step S402). A full-color pattern corresponding to the OSD is displayed when the OSD is activated (step S403) and a layer with a black and 50% transparent background is rendered and the scroll-in effect (the halation scroll-in effect) is displayed (step S404).
It is determined whether the OSD is switched to off (step S405). It is determined whether display of the full-color pattern reaches a predetermined time if the OSD is not switched to off (step S406). The layer with the black and transparent background is rendered and 50% transparent background and the scroll-out effect (the halation scroll-out effect) is displayed, if the display of the full-color pattern reaches the predetermined time, and the full-color pattern is faded (step S407).
If the OSD is switched to off, the gray out effect is displayed and the full-color pattern is converted to a gray-level pattern when the OSD does not provide the on and off modes (step S408), and the scroll-out effect (the halation scroll-out effect) is not displayed and the gray-level pattern is faded when the display thereof reaches the predetermined time (step S409).
If the OSD is switched to off, a full-color pattern corresponding to the off mode is displayed when the OSD provides the on and off modes (step S410), the layer with the black and 50% transparent background is rendered and the scroll-in effect is displayed (step S411), and the full-color pattern corresponding to the off mode is faded when display of the full-color pattern corresponding to the off mode reaches the predetermined time (step S412)
