Abstract
The present disclosure provides a device and a method for detecting a screen freeze error of a display of a vehicle. The method comprises monitoring a drive pattern of at least one pixel in a porch area during a time period corresponding to a plurality of image frames, wherein the porch area including at least one of a front porch area and a back porch area of a display panel driven according to the plurality of image frames; and determining occurrence of a screen freeze error by comparing the drive pattern of the at least one pixel with a preset drive pattern.
Claims12
A method for detecting a screen freeze error of a display device in a vehicle, the method comprising:
- monitoring a drive pattern of at least one pixel in a porch area during a time period corresponding to a plurality of image frames, wherein the porch area including at least one of a front porch area and a back porch area of a display panel driven according to the plurality of image frames;
- determining occurrence of a screen freeze error by comparing the drive pattern of the at least one pixel with a preset drive pattern that includes an RGB value and a flicker period of the at least one pixel;
- and
- determining that a screen of the display device is blackout when the at least one pixel displays a specific RGB value.
A method for assisting detection of a screen freeze error of a display device in a vehicle, the method comprising:
- generating a plurality of image frames including pixel data to be displayed by at least one pixel in a porch area including at least one of a front porch area and a back porch area of a display panel, wherein the at least one pixel has a drive pattern that includes an RGB value and a flicker period when the display panel is driven according to the plurality of image frames;
- and
- providing the plurality of image frames to a driver circuit of the display panel,
- wherein the drive pattern of the at least one pixel is used to determine occurrence of a screen freeze error through comparison with a preset drive pattern,
- wherein it is determined by a detecting device that the screen of the display device is blackout when the at least one pixel displays a specific RGB value.
A device for detecting a screen freeze error of a display device in a vehicle, the device comprising:
- a monitoring unit configured to monitor a drive pattern of at least one pixel in a porch area during a time period corresponding to a plurality of image frames, wherein the porch area including at least one of a front porch area or a back porch area of a display panel driven according to the plurality of image frames;
- and
- a determining unit configured to determine occurrence of a screen freeze error by comparing the drive pattern of the at least one pixel with a preset drive pattern that includes an RGB value and a flicker period of the at least one pixel, and determine that a screen of the display device is blackout when the at least one pixel displays a specific RGB value.
An assistance device for assisting detection of a screen freeze error of a display device in a vehicle, the assistance device comprising:
- a generating unit configured to generate a plurality of image frames including pixel data to be displayed by at least one pixel in a porch area including at least one of a front porch area or a back porch area of a display panel, wherein the at least one pixel has a drive pattern that includes an RGB value and a flicker period when the display panel is driven according to the plurality of image frames;
- and
- a providing unit configured to provide the plurality of image frames to a driver circuit of the display panel,
- wherein the drive pattern of the at least one pixel is used to determine occurrence of a screen freeze error through comparison with a preset drive pattern,
- wherein it is determined by a detecting device that the screen of the display device is blackout when the at least one pixel displays a specific RGB value.
