Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the process flow diagram of the touch screen display management method of the onboard system of one embodiment of the invention;
Fig. 2 is the logic diagram of the touch screen display management device of the onboard system of one embodiment of the invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The present invention proposes a kind of touch screen display management method of onboard system, the touch-control maloperation likely produced when touch screen display maps the external image of coming is shielded by the blank interface of top set in the touch interface of the current display of touch screen, and the blank interface of closedown returns touch interface after the display of end external image, switch with the freedom and flexibility realized between onboard system and external image source.
Fig. 1 shows the process flow diagram of the touch screen display management method of onboard system according to an embodiment of the invention.As shown in Figure 1, the touch screen display management method 100 of this onboard system comprises the steps:
Step S110, receives external image source input signal, the touch interface of the current display of touch screen generates the blank interface of a top set.Wherein, described external image source input signal can trigger when the outside audio-video interface of onboard system is connected with external image source generator, also can trigger when onboard system receives the audio-video signal of external image source generator transmission.Such as, when the AV-IN interface of vehicle-carrying DVD device access onboard system, or when the audio-video signal of vehicle-carrying DVD device imports onboard system into by AV-IN interface, single-chip microcomputer triggers this external image input signal, and notifies Android (Android) operating system.Again such as, when reverse image system is by Camera utilizing camera interface access onboard system, or when the signal of video signal of reverse image system imports onboard system into by Camera utilizing camera interface, single-chip microcomputer triggers this external image input signal, and notifies Android operation system.Android operation system, when receiving this external image input signal, generates a blank interface (the blank interface of preferably clear) juxtaposition and withstands on before the touch interface of the current display of touch screen.Now, user only can act on this blank interface to the touch control operation of touch screen, touch interface below in can not putting, thus can avoid maloperation.
Step S120, is mapped to touch-control screen display by external image source.This is prior art, therefore does not repeat them here.
Step S130, receives external image source cut-off signal, closes the blank interface of described top set, return described touch interface.Wherein, described external image source cut-off signal can trigger when the outside audio-video interface of onboard system and external image source generator disconnect, and also can trigger when onboard system does not receive the audio-video signal of external image source generator transmission.Such as, when vehicle-carrying DVD device is extracted from the AV-IN interface of onboard system, or when onboard system does not receive the audio-video signal that vehicle-carrying DVD device imported into by AV-IN interface, single-chip microcomputer triggers this external image cut-off signal, and notifies Android (Android) operating system.Again such as, when reverse image system is extracted from the Camera utilizing camera interface of onboard system, or when onboard system does not receive the signal of video signal that reverse image system imported into by Camera utilizing camera interface, single-chip microcomputer triggers this external image cut-off signal, and notifies Android operation system.Android operation system, when receiving this external image cut-off signal, is closed the blank interface of the top set generated in step S110, is made touch screen return original touch interface.Now user can continue to carry out touch control operation to onboard system.
Based on the touch screen display management method of above-mentioned onboard system, the present invention also proposes a kind of touch screen display management device of onboard system.Fig. 2 is the logic diagram of the touch screen display management device 200 of the onboard system of one embodiment of the invention.As shown in Figure 2, this device 200 comprises signal receiving module 210, touch interface administration module 220 and external image source display module 230.Signal receiving module 210 is for receiving external image source input signal and external image source cut-off signal.In specific embodiment, external image source input signal can trigger when the outside audio-video interface of onboard system is connected with external image source generator, also can trigger when onboard system receives the audio-video signal of external image source generator transmission.Similarly, external image source cut-off signal can trigger when the outside audio-video interface of onboard system and external image source generator disconnect, and also can trigger when onboard system does not receive the audio-video signal of external image source generator transmission.Touch interface administration module 220 is for receiving external image source input signal during at signal receiving module 210, the touch interface of the current display of touch screen generates the blank interface (the blank interface of preferably clear) of a top set.Blank interface top set is before the touch interface of touch screen, and like this, user only can act on this blank interface to the touch control operation of touch screen, touch interface below in can not putting, thus can avoid maloperation.Touch interface administration module 220 is also for receiving external image source cut-off signal during at signal receiving module 210, the blank interface of the front top of closedown, returns the touch interface of touch screen, so that user continues to carry out touch control operation to onboard system.External image source display module 230 is for being mapped to touch-control screen display by external image source.External image source is mapped to touch-control screen display by relevant external image source display module 230, and this is prior art, therefore does not repeat them here.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
