Description

Display device and electronic device

Technical Field

The utility model relates to an automotive filed, concretely relates to display device and electron device.

Background

More and more vehicle-mounted display devices, such as display devices of infotainment systems, integrate touch buttons, such as volume buttons, on a panel, when fingers of a driver and passengers touch the touch buttons on the panel, the buttons do not have direct feedback, so that the driver and passengers do not know whether the touch buttons are effectively touched, and only when the change of a volume display picture or the change of an actual volume in a display area on the panel is observed, the driver and passengers can confirm that the touch buttons are effectively touched, and the human-computer interaction experience is poor.

Disclosure of Invention

To the problem that exists among the prior art, the to-be-solved problem of the utility model is to provide a display device through providing LED light feedback for touch button for driver and crew can in time confirm effectively touch button, improve human-computer interaction and experience.

The utility model provides a display device, including panel, leaded light spare, PCB board and back lid, be provided with display screen and one or more touch button on the panel, be provided with the controller on the PCB board and correspond to touch button's LED, the light that LED sent can shine touch button through leaded light spare on, the output of every touch button is connected to the first input of controller, and when touch button was touched, the controller received the signal and is controlled the luminance of the LED that touch button corresponds changes.

Further, a first output end of the controller outputs a PWM signal to control the brightness of the LED corresponding to the touch button.

Further, when the touch button is touched, the corresponding LED brightness changes for a set time.

Further, when the set time is over, the corresponding LED brightness is restored to the default brightness.

Further, when the touch button is touched, the brightness of the corresponding LED increases or flickers.

Further, when the touch button is touched, the brightness of the corresponding LED is the first set brightness.

Further, the brightness of the corresponding LED periodically changes between a second set brightness and a third set brightness, and the second set brightness is smaller than the third set brightness.

The utility model also provides an electronic device, including foretell display device.

Further, the electronic device is a meter or an infotainment system.

Compared with the prior art, the utility model provides a display device and electron device has following beneficial effect: by providing LED light feedback for the touch buttons, drivers and passengers can confirm that the touch buttons are effectively touched in time, and the human-computer interaction experience is improved.

Detailed Description

As shown in fig. 1, a display device according to an embodiment of the present invention is, for example, a display device of a meter or a display device of an infotainment system.

The display device comprises a panel 1, a light guide member 4, a PCB 5 and a rear cover (not shown), wherein the panel 1 is provided with a display screen 2 and one or more touch buttons 3, as shown in FIG. 2, the PCB 5 is provided with a controller (not shown) and LEDs 51 corresponding to the touch buttons 3, light emitted by the LEDs 51 can irradiate the touch buttons 3 through the light guide member 4, the output end of each touch button 3 is connected to the first input end of the controller, and when the touch buttons 3 are touched, the controller receives signals and controls the brightness of the LEDs 51 corresponding to the touch buttons 3 to change, so that drivers and passengers can timely confirm that the touch buttons are effectively touched, and the human-computer interaction experience is improved.

The first output end of the controller outputs a PWM signal to control the brightness of the LED51 corresponding to the touch button 3, and when the touch button is touched, the brightness of the corresponding LED changes for a set time, for example, 1 second or 2 seconds.

When the set time is over, the corresponding brightness of the LED is restored to the default brightness, for example, the duty ratio of the PWM signal corresponding to the default brightness is 0%, that is, the LED is not lighted; or the duty ratio of the PWM signal corresponding to the default brightness is n%, i.e., the LED is turned on.

When the touch button 3 is touched, the brightness of the corresponding LED51 is increased, the brightness of the corresponding LED51 is the first set brightness L1, and the duty ratio of the PWM signal corresponding to the first set brightness L1 is greater than 0% or n%, so that the brightness of the touch button 3 is increased to make the driver and the passenger recognize that the touch button 3 is effectively touched.

In another embodiment, when the touch button 3 is touched, the corresponding LED51 flickers, that is, the brightness of the corresponding LED51 periodically changes between the second set brightness L2 and the third set brightness L3, the second set brightness L2 is less than the third set brightness L3, for example, the duty ratio of the PWM signal corresponding to the second set brightness L2 is 0%, the duty ratio of the PWM signal corresponding to the third set brightness L3 is 100%, the duty ratio of the PWM signal increases from 0% to 100% every 100 milliseconds, and then decreases from 100% to 0%, and the LED51 flickers.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited thereto. Various changes and modifications can be made by one skilled in the art without departing from the spirit and scope of the invention, and the scope of the invention is to be determined by the appended claims.
