Display device

Abstract

The invention provides a display device which has good chromaticity consistency and good visual comfort. The display device has a visible area and a non-visible area. The display device comprises a first laminated structure and a second laminated structure. The first laminated structure is located in the visible area. The second laminated structure is located in the non-visible area. The visible light has a first chromaticity after being reflected by the first laminated structure, the visible light has a second chromaticity after being reflected by the second laminated structure, and the CIE chromaticity difference between the first chromaticity and the second chromaticity is smaller than 3. The first laminated structure has a first average reflectance to visible light, the second laminated structure has a second average reflectance to visible light, and the first average reflectance and the second average reflectance are less than 3%. The display device has an average reflectivity difference value to visible light, and the average reflectivity difference value is smaller than 2%.

Description

technical field [0001] The invention relates to a display device. Background technique [0002] Existing display devices include a display area and a frame area as a non-display area, and the frame area is usually made of black ink. When the display screen of the display device is not lit, the reflectance and chromaticity of the visible light are different in degree between the display area and the non-display area of ​​the display device. For example, the average reflection difference of visible light between the display area and the non-display area of ​​the existing display device or the display device including the touch module is greater than 3%, and the visible light passing through the display area and the non-display area respectively The CIE chromaticity difference value is greater than 3. Therefore, the reflection spectrum distribution of the display area and the non-display area of ​​the existing display device is not continuous, so the display area and the non-...

Problems solved by technology

For example, the average reflection difference of visible light between the display area and the non-display area of ​​the existing display device or the display device including the touch module is greater than 3%, and the visible light passing through the display area and the non-display area respectively The CIE chromaticity difference is greater than 3

Therefore, the reflection spectrum distribution of the display area and the non-display area of ​​the existing display device is not continuous, therefore, the display area and the non-display area can be clearly distinguished visually, which is not conducive to aesthetics.

In addition, if the reflectance of the display device is not treated to reduce the reflection, the reflectance will generally be high, and the user is more likely to be visually disturbed by the reflected light from the background ambient light source, which will affect the operation of the panel
