Referring to fig. 1, fig. 1 is a schematic structural diagram of a flexible display module according to a first embodiment of the present application. The flexible display module 10 is applied to a display terminal including at least one hinge 60. Referring to fig. 2, the flexible display module 10 includes a flexible display panel 11, and fig. 2 is a schematic structural diagram of a first embodiment of the flexible display panel in the flexible display module provided in the present application. In this implementation scenario, the position of the rotating shaft 60 corresponds to the center of the flexible display module 10, and in other implementation scenarios, the rotating shaft 60 may also correspond to any position of the flexible display module 10. The flexible display panel 11 includes a display region 112 and a display region 113, and the display region 112 and the display region 113 can be folded around the rotation axis 60. Referring to fig. 3, fig. 3 is a schematic structural diagram of an embodiment of a flexible display panel of the flexible display module provided in the present application after being folded.
In this implementation scenario, the display terminal to which the flexible display module 10 is applied is provided with one rotating shaft 60, and in other implementation scenarios, the display terminal to which the flexible display module 10 is applied is provided with two or more rotating shafts, and correspondingly, the flexible display panel includes three or more display areas. Referring to fig. 4, fig. 4 is a schematic structural diagram of a flexible display panel in a flexible display module according to a second embodiment of the present disclosure. The display terminal to which the flexible display module 20 is applied is provided with two rotating shafts 71 and 72, and the flexible display panel 21 includes a display area 213, a display area 214, and a display area 215. Two adjacent display regions 213 and 215 can be folded around the rotation shaft 71, and two adjacent display regions 214 and 215 can be folded around the rotation shaft 72.
The flexible display module 10 further comprises two image capturing devices 121 and 122. The image capturing devices 121 and 122 are located on a side of the flexible display module 10 opposite to the user, and are located on the back sides of the display area 112 and the display area 113 in the present implementation scene, respectively, for capturing images when the flexible display module 10 is used. The image capturing devices 121 and 122 are further configured to analyze the captured image and obtain an angle of the user's line of sight with respect to a main optical axis of the image capturing device 121 or 122.
With continued reference to fig. 2, in the present implementation scenario, the image capturing device 121 and the image capturing device 122 are disposed corresponding to the display area 112 and the display area 113, respectively. For example, the image pickup device 121 corresponds to the center of the display area 112, and the image pickup device 122 corresponds to the center of the display area 113. In other implementations, image capturers 121 and 122 may correspond to any location of display area 112 and display area 113. In other implementation scenarios, there may be more image capturing devices, for example, 3, 4, etc., and the number of image capturing devices disposed corresponding to the display areas 112 and 113 may be equal or different, so long as at least one image capturing device is provided for each display area.
In this implementation scenario, the image capturing devices 121 and 122 capture images and perform image processing on the captured images, and taking the image capturing device 121 as an example for description, the working method of the image 122 is basically the same as that of the image capturing device 121, and is not described herein again.
The image capturing device 121 captures images periodically when the flexible display module 10 is in an operating state, and performs image processing on the captured images. Specifically, the image of the human head portrait and the image of the background in the acquired image are separated first, and in the present implementation scenario, the image of the human head portrait and the image of the background may be separated by using an image segmentation method. Image segmentation is a technique and process that divides an image into several specific regions with unique properties and proposes an object of interest. It is a key step from image processing to image analysis. The existing image segmentation methods mainly include the following categories: a threshold-based segmentation method, a region-based segmentation method, an edge-based segmentation method, a particular theory-based segmentation method, and the like.
After separating the image of the human head portrait from the background, the degree of the human head portrait deviating from the center of the collected image is calculated, specifically, the position of the center point of the human head portrait and the position of the center point of the collected image are calculated, the distance between the two positions of the center point is calculated, and the degree of the human head portrait deviating from the center of the collected image is calculated according to the distance. It is also possible to calculate the position of the center line of the human head and the position of the center line of the acquired image, calculate the distance between these two center line positions, and calculate the degree to which the human head deviates from the center of the acquired image with this distance. Or the distance between each point of the head portrait and the central point of the collected image can be calculated, the average value of the distances is calculated, and the degree of the head portrait deviating from the center of the collected image is calculated according to the average value. And calculating the included angle of the sight of the user relative to the main optical axis of the image acquisition device according to the degree of the human head image deviating from the center of the image.
In other implementation scenarios, after the acquired image is acquired, the human eye in the image is identified, the sight angle of the human eye is acquired, and the included angle of the user sight relative to the main optical axis of the image acquisition device is calculated according to the sight angle of the human eye.
In the present implementation scenario, since the image capture device 121 is located at the back of the center of the display area 112, the image capture device 122 is located at the back of the center of the display area 113. Therefore, the angle of the user's line of sight with respect to the main optical axis of the image pickup device 121 is taken as the angle of the user's line of sight with respect to the normal to the screen of the display area 112, and the angle of the user's line of sight with respect to the main optical axis of the image pickup device 123 is taken as the angle of the user's line of sight with respect to the normal to the screen of the display area 113. In other implementation scenarios, the image capturing devices 121 and 122 are only used for capturing images, and the flexible display module 10 further includes an image processing device, where the image processing device performs image processing on the images captured by the image capturing devices 121 and 122, and the processing method is substantially the same as that described above, and calculates the angle difference between the normal of the screen surface of the display area 112 and the display area 113 and the line of sight of the user.
In this implementation scenario, the flexible display panel 11 has a good visible light transmittance, and the image capturing devices 121 and 122 can capture images including the user and the surrounding environment through the flexible display panel 11. The imaging specification of the image pickup devices 121 and 122 is a single color QQVGA (Quarter VGA (Video Graphics Array), 1/4 size of standard VGA resolution). In other implementations, the imaging specifications of image capture devices 121 and 122 may be color, or other dimensions.
The flexible display module 10 further includes a display driving chip 13, the display driving chip 13 is electrically connected to the image capturing devices 121 and 122, and the display driving chip 13 adjusts display parameters of the display area 112 and the display area 113 according to an angle difference between a normal line of a screen surface of the display area 112 and a normal line of a screen surface of the display area 113 acquired by the image capturing device 121 and the image capturing device 112 and a line of sight of a user, so that display effects of the display area 112 and the display area 113 of the flexible display panel 11 are the same.
Specifically, the variation characteristic of the optical quality of the flexible display panel 11 with the angle may be stored in the display driving chip 13 in advance through an experimental method or a computer simulation method. The display driving chip 13 performs specific correction compensation on the display area 112 and the display area 113 of the flexible display panel 11 by using image processing methods such as brightness correction and chromaticity correction according to the angle difference between the normal lines of the display areas 112 and 113 and the line of sight of the user, and the change characteristic of the optical quality with the angle, so that the overall optical quality of the flexible display panel 11 is kept consistent.
In other implementation scenarios, a convolutional neural network may also be used to obtain display parameters for adjusting display region 112 and display region 113. Convolutional Neural Networks (CNN) are a class of feed forward Neural Networks (fed forward Neural Networks) that contain convolution computations and have a deep structure, and are one of the representative algorithms for deep learning (deep). The convolutional neural network has a representation learning (representation learning) capability, and can perform shift-invariant classification (shift-invariant classification) on input information according to a hierarchical structure of the convolutional neural network. The convolutional neural network is constructed by imitating a visual perception (visual perception) mechanism of a living being, can perform supervised learning and unsupervised learning, and has the advantages that the convolutional neural network can learn grid-like topologic features such as pixels and audio with small calculation amount, has stable effect and has no additional feature engineering (feature engineering) requirement on data due to the fact that convolutional kernel parameter sharing in an implicit layer and sparsity of connection between layers.
For example, the angle difference between the normal lines of the panels of the display area 112 and the display area 113 and the user's gaze and the corresponding adjusted display parameter value may be input to a convolutional neural network for training a plurality of times before, and after the training is completed, the angle difference between the normal lines of the panels of the display area 112 and the display area 113 obtained this time and the user's gaze may be input, so that the corresponding adjusted display parameter value may be obtained, and the adjustment may be performed according to the adjusted parameter value.
In this implementation scenario, the display parameters of the display area 113 may be adjusted with reference to the display effect of the display area 112, so that the display effects of the flexible display panel 11 are consistent. In another implementation scenario, the display parameters of the display area 112 may be adjusted with reference to the display effect of the display area 113, so that the display effects of the flexible display panel 11 are consistent. In addition, the display parameters of the display area 112 and the display area 113 can be adjusted simultaneously, so that the display effects of the display area 112 and the display area 113 of the flexible display panel 11 are consistent. In this implementation scenario, the display parameters include display brightness, color coordinates, contrast, sharpness, color temperature, and the like.
According to the description, the flexible display panel in the flexible display module comprises at least two display areas capable of being folded around the reel, at least two image acquisition devices are arranged corresponding to the at least two display areas and used for acquiring the angle difference between the normal line of the screen surface of the at least two display areas and the sight line of a user, and the display driving chip adjusts the display parameters of the at least one display area according to the angle difference, so that the display effects of the at least two display areas of the flexible display panel are consistent, and the display quality of the flexible display module is effectively improved.
