Problems solved by technology

However, it takes a certain amount of time for the screen to rise from the TV cabinet to the highest point. When the machine is turned on, all the images of the machine will be projected to the global position. The background of the projection area of ​​the external light machine is not white or the surface is smooth, which will cause color errors or glare of the projected image, resulting in poor user experience

Abstract

The invention discloses a display device so that an image displayed in the screen unfolding or folding process can be matched with an effective display area of a screen, the displayed image can rise along with rising of the screen, it is avoided that the image is exposed out of the screen, and the user experience is improved. The display device includes: a projection component; a screen; a driving assembly; a monitoring assembly which is used for monitoring state information in the screen unfolding or folding process and feeding back the state information of the screen to the controller; the controller which is used for: determining the height of the current screen according to the state information of the screen in the process that the screen is unfolded or folded according to a preset speed curve and the projection assembly projects a preset image according to a preset height curve; dividing the preset image into a first image and a second image according to the height of the current screen if the height of the current screen is lower than the display height of the preset image, wherein the height of the second image is not larger than the height of the current screen; and controlling the projection assembly to project a preset image so that the screen only displays the second image.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 202010603016.7 and the title of the invention "a display device" submitted to the China Patent Office on June 29, 2020, the entire contents of which are incorporated in this application by reference. technical field [0002] The present application relates to the field of display technology, in particular to a display device. Background technique [0003] Laser TV is a TV product that uses a laser light source as a display light source and cooperates with projection display technology to form images. It is equipped with a special projection screen and can receive broadcast TV programs or Internet TV programs. In the related art, laser TV not only adopts the screen unfolded from top to bottom, but also adopts the screen unfolded from bottom to top in the TV cabinet. The latter is to set the optical machine and the curling screen in the TV cabinet. When the TV is turned on...
