Method for viewing specific section display area and realization method thereof

Abstract

The invention relates to a method for viewing a specific section display area and a realization method thereof. An upper display layer is arranged above a lower display layer in a digital device screen and laminated, the upper display layer is a transparent or light-transmitting display panel, the upper display layer and the lower display layer are connected with a digital device processor, the upper display layer controls all or partial area through current, and the upper display layer and the lower display layer are from the same signal source; the upper display layer includes a similar color display area, a similar color display area boundary, an adjacent color display area and an adjacent color display area boundary, and a transparent and light-transmitting area is distributed between the similar color display area and the adjacent color display area; and the lower display layer includes a sampling operation area, a sampling operation area boundary, an adjacent sampling operation area and an adjacent sampling operation area boundary. The peep prevention problem of the screen can be solved, and ghost and light and shade change do not appear so as to have the effect of graphic interference on peeping of others.

Description

technical field [0001] The invention relates to a method and an implementation method for viewing a specific fan-shaped display area, and belongs to the technical field of display security. Background technique [0002] In the display technology of the screen, the existing technologies include 4, namely: [0003] 1. Long-lasting structure shelter: [0004] This technology is to add a long-lasting occlusion structure in the display area, such as the form of blinds, the form of cross grid, or the compact geometric shape, but most of them will affect the picture displayed on the display screen itself, resulting in affecting the normal viewing Using it will cause visual fatigue or vision loss. [0005] 2. Arrangement pattern of electronics and light source control: [0006] This technology mostly uses polarizers or the visual difference of different light sources. The known technology is to use the optical characteristics of VA liquid crystals, and use different regional brig...

Problems solved by technology

[0010] In this old technology, when under the anti-peeping mode, the side viewer will see a black and white grid pattern, but the user can still operate the computer normally, but because the anti-peeping effect layer and the display layer are the same layer, there is no actual obstruction , the anti-peeping method is more inclined to use patterns to interfere with the side-viewer's line of sight, rather than completely invisible. When the user moves the head slightly or the relative positions of the hands are different, there will be adverse effects of flickering
