AI Technical Summary

Technical Problem

Existing texture screen technology cannot simultaneously meet the dual requirements of high-quality texture display when the screen is off and high color gamut, high color accuracy and high definition display when the screen is on. It is also prone to optical interference such as moiré patterns and water ripples, resulting in poor color consistency.

Method used

A dual-layer micro-nano textured film structure is adopted, in which the subwavelength grating bottom layer and the decorative micro-nano textured surface layer are different from each other. Combined with a pixel-level dynamic color gamut compensation model, moiré patterns are suppressed by adjusting grating parameters and material properties, and spectral attenuation and hue correction are performed on the RGB three channels.

Benefits of technology

It achieves a balance between high-quality texture when the screen is off and high-definition display when the screen is on, completely suppresses moiré patterns, improves color gamut, color accuracy and saturation, and is suitable for use in multiple scenarios.

Abstract

The application discloses a kind of double-layer micro-nano texture film and pixel-level dynamic color gamut compensation's screen-off display device and method, the device includes driving backplate, microcrystalline light-emitting chip array, optical adhesive, double-layer micro-nano texture film, surface protective layer and control driving module, core in double-layer micro-nano texture film: bottom layer is subwavelength grating, realize near zero reflection and inhibit moire;Surface layer is non-periodic random decorative microstructure, ensure high-quality texture when screen-off time.It is established compensation mapping library by pre-pixel-by-pixel calibration RGB three-channel spectral attenuation and color gamut loss parameter on method;Bright screen time by control driving module to each pixel independently carries out three-channel gain, hue, saturation and dynamic compensation of color gamut range, accurate correction color deviation.The application solves the technical contradiction that traditional texture screen cannot consider screen-off decorative texture and bright screen high color gamut high color accuracy display, eliminates moire interference, greatly improves color performance, and process compatibility is strong, easy to mass production.
