In an embodiment of the present invention, please refer to fig. 1, which illustrates a flow chart of steps of a touch-based transparent and opaque one-key switching method 1 for an intelligent vehicle window according to an embodiment of the present invention. The touch-based transparent and opaque one-key switching method 1 for the intelligent vehicle window comprises the following steps 101-103, wherein:
Specifically, the touch screen usually further includes a plurality of applications and other buttons, when a user clicks the touch screen, a first signal is generated, and the touch driver board on the touch screen generates content of the corresponding first signal according to a touch position.
When the touch driving board judges that the click position is the position of the one-key switching button, namely the one-key switching button is clicked, the content of the generated first signal is a one-key transparent signal.
Specifically, after the mainboard receives and identifies that the content of the first signal is a one-key transparent signal, if the display screen is a transparent organic light emitting diode screen, a corresponding second signal is a full black picture signal below 32 gray scales and is sent to the screen driving board; if the display screen is a transparent liquid crystal display screen, the corresponding second signal is a full white picture signal with a gray scale of more than 200, and is sent to the screen driving board, but not limited thereto.
And step 103, controlling the display screen. And after the screen driving board receives the second signal, the display screen is controlled to be in a fully transparent state according to the second signal.
Specifically, if the second signal received by the screen driving board is a full black picture signal with a gray scale below 32, the display screen is controlled to be in a full transparent state, and the full transparent state at this time is a full black picture with a gray scale below 32; if the second signal received by the screen driving board is a full white picture signal with a gray scale of more than 200, the display screen is controlled to be in a full transparent state, and the full transparent state is a full white picture with a gray scale of more than 200, but not limited thereto.
In a preferred embodiment, in step 101, when the touch driver board on the touch screen determines that the click position is the position of the main screen button when the first signal is generated, the content of the first signal is a main interface display signal, and the main interface display signal is sent to the main board.
Specifically, when the touch driver board on the touch screen judges that the click position is the position of the main screen button, that is, when the main screen button is clicked, the content of the generated first signal is the main display interface signal.
Specifically, the main board recognizes the content of the first signal as a display main interface signal, generates a corresponding third signal, and sends the display main interface signal to the screen driving board.
And step 103, controlling the display screen. And after the screen driving board receives the third signal, controlling the display screen to display the main interface according to the third signal.
Specifically, after the screen driving board receives the third signal, the screen driving board controls the display screen to display the main interface according to the third signal.
In a preferred embodiment, in step 101, when the touch driver board on the touch screen determines that the click position is not the position of the button, the content of the first signal is a touch screen position signal and is sent to the main board.
Specifically, when the click position is a position other than the position of the button, for example, the click position is a blank area of a plane, or when the palm is used for wiping on the screen, the touch driver board determines the position of the screen touched by the palm, generates a first signal, and the content of the first signal at this time is a touch screen position signal and sends the touch screen position signal to the main board.
Specifically, after the main board receives and identifies that the content of the first signal is a touch screen position signal, if the display screen is a transparent organic light emitting diode screen, a corresponding fourth signal is a local black picture signal with a gray scale below 32, and the local black picture signal is sent to a screen drive board; and if the display screen is a transparent liquid crystal display screen, generating a corresponding local white picture signal with the second signal being more than 200 gray scales, and sending the local white picture signal to the screen driving board.
And step 103, controlling the display screen. And after receiving the fourth signal, the screen driving board controls the display screen to be in a local transparent state at the position of the touch screen according to the fourth signal.
Specifically, if the fourth signal received by the screen driving board is a local black picture signal below 32 gray scale, the display screen is controlled to be in a local transparent state (at the position of the touch screen), and the local transparent state is a local black picture below 32 gray scale, so that the position on the car window screen, which is touched or clicked by only the palm of the passenger, is in a transparent state; if the fourth signal received by the screen driving board is a local white picture signal with more than 200 gray scales, the display screen is controlled to be in a local transparent state, the local transparent state at this moment is a local white picture with more than 200 gray scales, and the situation that only the position touched or clicked by the palm of the passenger on the car window screen is in the transparent state is achieved, but the situation is not limited to the situation.
Meanwhile, the first signal is continuously generated along with the movement of the palm of the passenger on the screen, and then a black picture below 32 gray scales can be displayed at the position touched by the palm, so that the partial transparency of the OLED display screen or a white picture above 200 gray scales can be realized, and the partial transparency of the LCD display screen can be realized.
