Abstract

The present disclosure relates to display devices and imaging control methods of a display device. One example display device includes a display, a lens assembly, a driver, and a controller. The controller is configured to convert a first image into n consecutive second images, and generate a drive signal used to control the driver to move, where an image resolution of the second image is less than an image resolution of the first image, a refresh rate of the second image is greater than a refresh rate of the first image, and n≥2. The driver is configured to drive, under control of the drive signal, at least one optical element or the display connected to the driver to move to adjust a display location of the second image displayed by the display, so that the n consecutive second images are displayed at n different locations.

Dependent claims

A display device, comprising:

a display;
a lens assembly located on an optical path of the display;
a driver;
and
a controller, wherein:
the lens assembly comprises at least one optical element;
the controller is configured to receive a first image to be displayed, convert the first image into n consecutive second images, and generate a drive signal used to control the driver to move, wherein an image resolution of the second image is less than an image resolution of the first image, a refresh rate of the second image is greater than a refresh rate of the first image, n≥2, and n is an integer;
the display is configured to display the n consecutive second images in a time-division manner under control of the controller;
the driver is connected to the at least one optical element in the lens assembly, or the driver is connected to the display;
and
the driver is configured to drive, under control of the drive signal, a component connected to the driver to move to adjust a display location of the second image displayed by the display, wherein the n consecutive second images are displayed at n different locations.

An imaging control method of a display device, wherein the display device comprises a display, a lens assembly located on an optical path of the display, a driver, and a controller, wherein the lens assembly comprises at least one optical element, and the driver is connected to the at least one optical element in the lens assembly, or the driver is connected to the display;

and
wherein the imaging control method comprises:
receiving, by the controller, a first image to be displayed;
converting, by the controller, the first image into n consecutive second images;
generating, by the controller, a drive signal used to control the driver to move, wherein an image resolution of the second image is less than an image resolution of the first image, a refresh rate of the second image is greater than a refresh rate of the first image, n≥2, and n is an integer;
displaying, by the display, the n consecutive second images in a time-division manner under control of the controller;
and
driving, by the driver under control of the drive signal, a component connected to the driver to move to adjust a display location of the second image displayed by the display, wherein the n consecutive second images are displayed at n different locations.
