AI Technical Summary
Technical Problem
The reflectivity control precision of electronic paper displays is poor when bent, which affects the accuracy and display effect of grayscale display.
Method used
By setting reference pixels at the edge of the electronic paper display, applying a constant voltage and using a measuring light source and photoreceptor to collect reflectance in real time, the curved area is determined based on the reflectance change, and the driving voltage of the display pixels is adjusted through a pre-established driving function to maintain reflectance accuracy.
Benefits of technology
The reflectivity control accuracy in bending conditions is improved, ensuring the accuracy of grayscale display and improving the display effect.

Abstract
The present invention discloses a bending-resistant driving method for an electrowetting electronic paper display, comprising: applying a first preset voltage to each reference pixel on the outer edge of the electronic paper display in response to the electronic paper display receiving a display signal; activating a measurement light source so that the measurement light source illuminates the reference pixels at a constant preset light intensity, and collecting a first reflectivity of each reference pixel via a photoreceptor; obtaining a first position of a reference pixel that does not meet the preset reflectivity and its corresponding first reflectivity; further obtaining a curved region and its first curvature information; obtaining a pixel curvature degree of each display pixel within the curved region based on the first curvature information; obtaining a corresponding drive function based on the pixel curvature degree; and driving the electronic paper display based on the drive function and display signal corresponding to each display pixel. The present invention can prevent the problem of a significant decrease in display quality when an electronic paper display is curved.
