Abstract

The invention provides a time display method based on an OSD semi-transparent mode, which comprises the following steps: step S1: in four side areas of the upper side, the lower side, the left side and the right side of a display screen, taking the center of the screen as a circle center, drawing a line segment at every 6 degrees, and distinguishing the line segments by different colors, wherein the line segments are 60 line segments in total, namely scales from 0 to 59 of a clock; step S2: the positions of the minute hand and the second hand are represented by semitransparent areas with different transparencies; the second hand changes the translucent area range every second with time. The OSD of the invention expresses the pointer by different semitransparent effects, so that the display effect is more beautiful and visual.

Description

Display time method based on OSD semi-transparent mode

Technical Field

The invention belongs to the field of display screen control, and particularly relates to a time display method based on an OSD (on screen display) semi-transparent mode.

Background

On the screen, a digital type clock or timer is displayed using OSD. The clock has two types of countdown and current time. The user needs to look to the clock or the timer to time, which easily causes distraction.

The area of the screen with the width of about 1 pixel (pixel) on the upper, lower, left and right sides is usually for aesthetic reasons, some space is reserved, important characters cannot be displayed, even if the number of pictures or characters is less than 1 pixel, the pictures or characters can be basically pieced together, and therefore the OSD message is displayed by using the area, and the operation of a user is hardly influenced.

Disclosure of Invention

The invention aims to provide a time display method based on an OSD semi-transparent mode.

The invention adopts the following technical scheme: a time display method based on the OSD semi-transparent mode comprises the following steps: step S1: in four side areas of the upper side, the lower side, the left side and the right side of a display screen, taking the center of the screen as a circle center, drawing a line segment at every 6 degrees, and distinguishing the line segments by different colors, wherein the line segments are 60 line segments in total, namely scales from 0 to 59 of a clock; step S2: the positions of the minute hand and the second hand are represented by semitransparent areas with different transparencies; the second hand changes the translucent area range every second with time.

Preferably, the widths of the upper, lower, left and right side regions are all about 1 pixel.

The invention also provides a time display method based on the OSD semi-transparent mode, which comprises the following steps: step S1: drawing a perfect circle at the center of the screen, and making 60 scales by taking 6 degrees as a scale, namely 0 to 59 scales of the clock; step S2: the positions of the minute hand and the second hand are represented by semi-transparent areas with different transparencies in a perfect circle; the OSD is not displayed outside the perfect circle, and the semitransparent effect is not achieved.

Further, the diameter of the perfect circle is not limited to the minimum distance of the visible area of the display, nor is the position limited to the center of the screen.

The OSD of the invention expresses the pointer by different semitransparent effects, so that the display effect is more beautiful and visual.

Detailed Description

The invention is further explained below with reference to the figures and the specific embodiments.

A time display method based on the OSD semi-transparent mode comprises the following steps: step S1: in four side areas of the upper side, the lower side, the left side and the right side of a display screen, taking the center of the screen as a circle center, drawing a line segment at every 6 degrees, and distinguishing the line segments by different colors, wherein the line segments are 60 line segments in total, namely scales from 0 to 59 of a clock; step S2: the positions of the minute hand and the second hand are represented by semitransparent areas with different transparencies; the second hand changes the translucent area range every second with time.

Preferably, the widths of the upper, lower, left and right side regions are all about 1 pixel. The four sides of the screen, the upper side, the lower side, the left side and the right side, and the area with the width of about 1 pixel, take the center of the screen as the center of a circle, draw a line segment every 6 degrees, and distinguish with different colors, and total 60 line segments, namely 0 to 59 scales of the rectangular clock, are shown in fig. 1. The hand position is indicated by a translucent area, and the translucency is set to be strong/weak, as indicated by a minute hand/hour hand in fig. 2, 3 minutes and 16 seconds, because the second hand changes the translucent area every second, the nearly immovable translucent area is the minute hand, and the translucent area moved every second is the second hand, so that the minute hand and the second hand can be clearly distinguished. Taking fig. 2 as an example, the second hand alone without the minute hand is 16 seconds.

In an embodiment of the invention, in the round method, a perfect circle is drawn at the center of the screen, and in the same method as the square clock, 60 scales are made with one scale every 6 degrees, and the outer frame of the circle is not required to be displayed. See in particular fig. 3.

In the same way as the square clock, the area of the semi-transparent part is in the circle, and no OSD is displayed outside the circle, and the semi-transparent effect is not achieved, as shown in fig. 4, 3 minutes and 16 seconds.

In the embodiment of the invention, the time representation mode is almost a full screen, so that the user does not need to look at a certain place to watch the time. The diameter of this circle is not limited to the minimum distance of the viewable area of the display nor is the location limited to the center of the screen, as shown in FIG. 5.

The above are preferred embodiments of the present invention, and all changes made according to the technical scheme of the present invention that produce functional effects do not exceed the scope of the technical scheme of the present invention belong to the protection scope of the present invention.
