Display device and control method thereof

Abstract

The invention provides a display device and a control method thereof. The display device includes a display panel and a camera module. The display panel includes a main screen area and first and second sub-screen areas; the camera module is arranged below the display panel and its position corresponds to the first and second sub-screen areas; area and the second sub-screen area are alternately in the non-display state at preset time intervals; after the first sub-screen area is in the non-display state, control the camera module to collect images through the first sub-screen area, control the main screen area and the second sub-screen area The sub-screen area normally displays the images collected by the camera module; after the second sub-screen area is in a non-display state, control the camera module to collect images through the second sub-screen area, and control the main screen area and the first sub-screen area to display the camera module normally The captured images. The present invention enables the full screen to display images synchronously and normally when the images are collected by the camera device under the screen, and can ensure that the algorithm time of the camera device is sufficient.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a control method thereof. Background technique [0002] In the field of electronic equipment terminals with display devices, currently the display panel pursues a screen-to-body ratio as large as possible to enhance user experience. For smartphones with a full-screen concept, various optical sensing elements such as front cameras, face recognition, and fingerprint recognition are expected to be integrated into the screen to achieve the "full-screen" effect that the screen occupies the entire front panel of the phone. [0003] One implementation method in the prior art is to arrange the above-mentioned optical sensing element (such as the front camera) under the display screen, and make slots or holes on the display screen corresponding to the position of the optical sensing device, but these The slotted or holed area cannot display the picture norma...

Problems solved by technology

[0005] However, the above-mentioned full-screen solution in the prior art cannot use the under-screen camera to take pictures or shoot videos without being affected by the screen in the normal preview display state. show

Especially in the state of collecting video, the conventional sampling frequency needs to be 30Hz (that is, 30 frames per second). If the frequency is too low, there will be a freeze phenomenon, and if the frequency is too high, the algorithm time will be insufficient.

Therefore, in the case of ensuring the video sampling frequency, it is also a technical problem to reserve enough algorithm time
