Abstract

Display cover glass includes a glass substrate. The glass substrate has a first panel and a second panel. An angle formed between the first panel and the second panel. The first panel has a first display area provided with an arbitrary first point. The second panel has a second display area provided with an arbitrary second point. The color difference value ΔE between the first point and the second point is less than or equal to 17 when the viewing angle difference between the first point and the second point is 10-60 degrees. The first panel and the second panel make it possible to display driving information, such as a navigation interface, and an operation interface in the two display areas respectively so that the driver of a means of transport can read the information clearly and use the operation interface with ease.

Claims (24)

1 . Display cover glass, comprising:

a glass substrate having a first panel and a second panel, wherein an angle is formed between the first panel and the second panel, the first panel has a first display area, the second panel has a second display area, the first panel is provided with an arbitrary first point, the second panel is provided with an arbitrary second point, and a color difference value ΔE between the first point and the second point is less than or equal to 17 when a viewing angle difference between the first point and the second point is 10-60 degrees;

wherein the first point has a 10-degree measuring angle on the first panel and the second point has a 60-degree measuring angle on the second panel from a same position between the interior of the angle respectively;

wherein an antireflection layer and an anti-fingerprint layer are formed on the surface of the first panel and of the second panel;

wherein the angle ranges from 120 to 175 degrees.

2 . The display cover glass of claim 1 , wherein the first point has an L*1 value, an a*1 value, and a b*1 value; the second point has an L*2 value, an a*2 value, and a b*2 value; and the color difference value ΔE between the first point and the second point satisfies the relation ΔE=√{square root over ((L*1−L*2) 2 +(a*1−a*2) 2 +(b*1−b*2) 2 )}≤7.

3 . Display cover glass, comprising:

a glass substrate having a first panel and a second panel, wherein an angle is formed between the first panel and the second panel, the first panel has a first display area, the second panel has a second display area, the first panel is provided with an arbitrary first point, the second panel is provided with an arbitrary second point, and a color difference value ΔE between the first point and the second point is less than or equal to 7 when a viewing angle difference between the first point and the second point is 10-50 degrees;

wherein the first point has a 10-degree measuring angle on the first panel and the second point has a 50-degree measuring angle on the second panel from a same position between the interior of the angle respectively;

wherein an antireflection layer and an anti-fingerprint layer are formed on the surface of the first panel and of the second panel;

wherein the angle ranges from 120 to 175 degrees.

4 . The display cover glass of claim 3 , wherein the first point has an L*1 value, an a*1 value, and a b*1 value; the second point has an L*2 value, an a*2 value, and a b*2 value; and the color difference value ΔE between the first point and the second point satisfies the relation ΔE=√{square root over ((L*1−L*2) 2 +(a*1−a*2) 2 +(b*1−b*2) 2 )}≤7.

5 . Display cover glass, comprising:

a glass substrate having a first panel and a second panel, wherein an angle is formed between the first panel and the second panel, the first panel has a first display area, the second panel has a second display area, the first panel is provided with an arbitrary first point, the second panel is provided with an arbitrary second point, and a color difference value ΔE between the first point and the second point is less than or equal to 4 when a viewing angle difference between the first point and the second point is 10-40 degrees;

wherein the first point has a 10-degree measuring angle on the first panel and the second point has a 40-degree measuring angle on the second panel from a same position between the interior of the angle respectively;

wherein an antireflection layer and an anti-fingerprint layer are formed on the surface of the first panel and of the second panel;

wherein the angle ranges from 120 to 175 degrees.

6 . The display cover glass of claim 5 , wherein the first point has an L*1 value, an a*1 value, and a b*1 value; the second point has an L*2 value, an a*2 value, and a b*2 value; and the color difference value ΔE between the first point and the second point satisfies the relation ΔE=√{square root over ((L*1−L*2) 2 +(a*1−a*2) 2 +(b*1−b*2) 2 )}≤4.

7 . Display cover glass, comprising:

a glass substrate having a first panel and a second panel, wherein an angle is formed between the first panel and the second panel, the first panel has a first display area, the second panel has a second display area, the first panel is provided with an arbitrary first point, the second panel is provided with an arbitrary second point, and a color difference value ΔE between the first point and the second point is less than or equal to 4 when a viewing angle difference between the first point and the second point is 10-30 degrees;

wherein the first point has a 10-degree measuring angle on the first panel and the second point has a 30-degree measuring angle on the second panel from a same position between the interior of the angle respectively;

wherein an antireflection layer and an anti-fingerprint layer are formed on the surface of the first panel and of the second panel;

wherein the angle ranges from 120 to 175 degrees.

8 . The display cover glass of claim 7 , wherein the first point has an L*1 value, an a*1 value, and a b*1 value; the second point has an L*2 value, an a*2 value, and a b*2 value; and the color difference value ΔE between the first point and the second point satisfies the relation ΔE=√{square root over ((L*1−L*2) 2 +(a*1−a*2) 2 +(b*1−b*2) 2 )}≤4.
