Alternatively, the display image may be a dynamic video image as well as a static picture image, i.e. the video source may be a video or a picture, or an animation or a power-on advertisement of the projector.
And S200, the projection assembly is switched to a starting initialization state from an ultra-low power consumption mode.
Specifically, the projection module is switched from the ultra-low power consumption mode to a startup initialization state, at this time, the projection device completes the preprocessing of the video source, and the display proportion of the display panel is zero.
S300, the projection component executes the turning on of the light source, and simultaneously the projection component sends a screen ascending instruction to the central control component.
Specifically, the projection component executes the turning on of the light source, and simultaneously the projection component sends a screen ascending instruction to the central control component.
S400, according to the screen ascending instruction, the curtain gradually ascends from low to high, and meanwhile the display panel in the projection assembly gradually increases from low to high in a segmented mode to display, wherein the increasing of the display height of the display panel and the rising height of the curtain keep proportion to increase synchronously, and the projection image of the display panel and the curtain are synchronously lifted.
Specifically, according to the screen ascending instruction, the curtain gradually ascends from low to high, and the display panel in the projection assembly gradually increases from low to high, wherein the increasing of the display height of the display panel and the rising height of the curtain keep proportional synchronous increase, so as to realize synchronous rising of the projection image of the display panel and the curtain, wherein the step S400 comprises:
s410, setting the curtain height Hmax in advance, and enabling the height of the projection image of the display height Pmax of the display panel to be consistent with the curtain height Hmax. The display height of the display panel is the height of a display area of the display panel, the display height Pmax is the maximum height of the display area, and a projection image displayed by the display height Pmax is consistent with the height Hmax of the curtain.
S420, according to the screen ascending instruction, the curtain gradually ascends from low to high: h0, H1, H2, H3,. Hmax, while the display panel of the projection assembly is incrementally displayed in segments of equal proportion from low to high: p0, P1, P2, P3,. Pmax. This application realizes increasing with the curtain height keeps proportion synchronization through the demonstration height of setting for display panel for the projecting image that realizes display panel rises with the curtain synchronization. It is thus clear that this application need not specific video source, and the display area height (display panel shows the line number) through setting for display panel comes to increase in step with the curtain height holding ratio, and then realizes that display panel's projecting image and curtain go up and down in step, and the projecting image can accurately follow the curtain and go up and down, realizes that projecting image and curtain reach perfect match, improves the user and uses experience.
For example, the curtain height Hmax, where the variable for the curtain to rise is HV, e.g., HV may be the difference between H1 and H0, the display image height of the display height Pmax of the display panel coincides with the curtain height Hmax, and the incremental variable for the display height is PV, e.g., PV may be the difference between P1 and P0, HV/Hmax = PV/Pmax.
For example, referring to fig. 5, the display height of the display panel increases in synchronization with the time axis, and the curtain-raising height increases in synchronization with the increase of the display height of the display panel.
Referring to FIG. 6, the increase of the height of the display area of the display panel is shown along with the change of time. For example, at time T0, the display area height of the display panel is zero, that is, the display height P0 of the display panel is zero, and as time increases, the display area height of the display panel gradually increases T0, T1, T2, and T3 until the display area height of the display panel reaches Pmax, that is, the projection image of the display panel can be projected in a full screen.
Assuming that it takes t =10 seconds for the curtain to rise from the lowest point to the highest point at a constant speed, the physical resolution of the display panel is 1920 × 1080, which means that 1920 pixels in each row of the display panel are present for 1080 rows, which means that the width of the display panel is 1920 pixels and the height of the display panel is 1080 pixels, and within 10 seconds for the rising of the matched curtain, the display panel must complete segmented incremental display from low to high within 10 seconds, that is, the display panel displays 0 pixel height at 0s, displays 108 pixels height at 1s, and displays 216 pixels height at 2 s. As mentioned above, the curtain height Hmax is zero at the 0s time of the curtain, 1s of the curtain reaches Hmax/10, and 2s of the curtain reaches Hmax/5.. 10s of the curtain reaches Hmax.

s500, whether the rising height of the curtain reaches the preset height is judged, when the rising height of the curtain does not reach the preset height, the curtain rising is continued, and when the rising height of the curtain reaches the preset height, the curtain rising is not executed.
Specifically, whether the curtain lifting height reaches the preset height is judged, when the curtain lifting does not reach the preset height, the curtain lifting is continued, and when the curtain lifting reaches the preset height, the curtain lifting is not executed.
Specifically, referring to fig. 2, the projection synchronous display method of the projection apparatus further includes the following steps:
s610, the projection component receives a shutdown command.
S620, the projection component sends a screen descending instruction to the central control component, the curtain descends gradually from high to low, and the display panel of the projection component is displayed in a gradually descending manner from high to low, wherein the descending of the display height of the display panel and the descending height of the curtain are synchronously reduced in proportion, so that the display image of the display panel and the curtain descend synchronously.
S630, judging whether the curtain descending height reaches the preset height, when the curtain descending does not reach the preset height, continuing to descend the curtain, and when the curtain descends to reach the preset height, not executing the curtain descending.
Specifically, the projection assembly sends a screen descending instruction to the central control assembly, the curtain descends gradually from high to low, and the display panel of the projection assembly is displayed in a gradually descending manner from high to low, wherein the descending of the display height of the display panel and the descending height of the curtain are synchronously reduced in proportion, so that the display image of the display panel and the curtain descend synchronously. Wherein, step S630 includes: according to the screen descending instruction, the screen descends gradually from high to low: hmax,.. H3, H2, H1, H0, while the display panel of the projection assembly is displayed by a high-to-low proportional piecewise decrease: pmax,. P3, P2, P1, P0. This application comes to descend with the curtain height holding ratio synchronization through the demonstration height that sets for display panel for realize display panel's projecting image and curtain descend in step.
For example, if the screen height Hmax is a variable of the screen descending is HV, the display image height of the display height Pmax of the display panel is equal to the screen height Hmax, and the decreasing variable of the display height is PV, HV/Hmax = PV/Pmax.
For example, referring to fig. 7, which shows the decrease of the display area height of the display panel and the change of time, the decrease of the display height of the display panel is associated with the time axis, and the drop height of the curtain is decreased in synchronization with the decrease of the display height of the display panel with the maintained ratio. For example, at time T0, the display area height of the display panel is Pmax, that is, the projected image of the display panel can be projected in a full screen, and as time increases, T0, T1, T2, and T3, the display area height of the display panel gradually decreases until the display area height of the display panel reaches P0, and the display area height of the display panel is zero, that is, the display panel cannot project the image.
Assuming that it takes t =10 seconds for the curtain to descend from the highest point to the lowest point at a uniform speed, the physical resolution of the display panel is 1920 × 1080, which means that each row of 1920 pixels of the display panel counts for 1080 rows, which means that the width of the display panel is 1920 pixels, and the height of the display panel is 1080 pixels, and within 10 seconds for the curtain to descend, the display panel must finish the step-by-step display from high to low within 10 seconds, that is, the display panel displays 1080 pixel height at the 0s, that is, the display height Pmax,9s displays 972 pixel height, and 2s displays 864 pixels high. As for the above curtain height Hmax, correspondingly, the curtain height Hmax is the 0 th curtain, the curtain height H0 is zero when the 1s curtain reaches 9 × Hmax/10 and the 2s curtain reaches 4 × Hmax/5.. 10 s.
