Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] refer to figure 1 and figure 2 A preferred embodiment of the display device 1 that prevents signal switching from causing abnormal picture display in the present invention includes a scaling controller (Scaler) 11, a microprocessor (Micro Controller Unit, MCU) 12 electrically connected to the scaling controller 11 , and a display 13 electrically connected to the scaling controller 11. In this preferred embodiment, the display device 1 adopts a high-definition multimedia interface whose version is "1.4" to receive an image signal, such as a 2D image or a 3D image.

[0024] The scaling controller 11 is used for receiving the image signal and generating an image frame.

[0025] The microprocessor 12 is used for obtaining the current timing data corresponding to the video signal according to the video signal. The current timing data includes a...

Abstract

Disclosed are a display method and equipment capable of preventing abnormal image display caused by signal switchover. The display method includes steps of receiving an image signal to acquire current time sequence data; judging whether the image signal is stable or not according to the current time sequence data and initial time sequence data; judging whether an image is generated or not if the image signal is stable; judging whether the current time sequence data include 3D (three dimensional) format indicating data or not if the image is generated; setting a current image format as the 3D format of an input signal if the 3D format indicating data are included; judging whether the current image format is matched with a display image format or not; if not, setting the display image format as the current image format; and repeatedly generating the image. The image can be normally outputted and displayed without repeatedly pulling and plugging a connector of a high-definition multimedia interface or restarting a display by users.

Description

technical field [0001] The present invention relates to an image display method and its display device, in particular to a display method and its display device for preventing abnormal picture display caused by signal switching. Background technique [0002] As 3D technology is becoming more and more mature, related products are gradually appearing in people's daily life, such as monitors capable of outputting 3D images. Generally speaking, the above-mentioned displays use the version "1.4" High Definition Multimedia Interface (HDMI) to receive source signals, images and digital data, such as 720p signals or 1080p signals, 2D images or 3D images. Among them, if the 3D screen is further distinguished by the arrangement of pixels (Pixel), it can be mainly divided into three types, which are Frame Packing, Side by Side, and Top and Top. Bottom) and so on. Digital data represents the arrangement of images. [0003] Normally, when the display continues to receive images, the d...
