Abstract

Systems and methods are disclosed for a mold frame for an information handling system that may include an outer portion configured to couple the mold frame to an exterior portion of a cover bottom of the display; a middle portion including an adhesive portion configured to couple the mold frame to a panel of the display; and an inner portion configured to contact an interior portion of the cover bottom, the inner portion including a color-changing material causing the inner portion to change from a first color to a second color, the first color causing the shadow around the display, the second color causing the shadow around the display to minimize.

Claims (48)

1. A mold frame configured to minimize a shadow around a display of an information handling system, the mold frame comprising:

an outer portion configured to couple the mold frame to an exterior portion of a cover bottom of the display;

a middle portion including an adhesive portion configured to couple the mold frame to a panel of the display; and

an inner portion configured to contact an interior portion of the cover bottom, the inner portion including a color-changing material causing the inner portion to change from a first color to a second color, the first color causing the shadow around the display, the second color causing the shadow around the display to minimize.

2. The mold frame of claim 1 , wherein the color-changing material is comprised of a photochromic pigment.

3. The mold frame of claim 2 , wherein causing the inner portion to change from the first color to the second color comprises:

absorbing, by the photochromic pigment, one or more wavelengths of light emitted by a light source of the display; and

causing, by the photochromic pigment, a photochemical reaction within the mold frame.

4. The mold frame of claim 1 , wherein the mold frame is within a field of view of a user via the panel of the display.

5. The mold frame of claim 1 , wherein the mold frame further comprises:

a reflector coupled to the cover bottom of the display, the reflector including:

a covering portion coupled to the inner portion of the mold frame, the covering portion having the second color causing the shadow around the display to minimize; and

a folding portion coupling the reflector to the covering portion.

6. The mold frame of claim 1 , wherein the first color is black.

7. The mold frame of claim 1 , wherein the second color is grey.

8. A method for minimizing a shadow around a display of an information handling system, the method comprising:

in response to the display being in an on state:

emitting, by a light source of the display, one or more wavelengths of light, the light source in an illuminated state;

receiving, by a mold frame of the display, the one or more wavelengths of light emitted by the light source, the mold frame including a color-changing material; and

causing, by the one or more wavelengths of light, the color-changing material to change from a first color to a second color, the first color causing the shadow around the display, the second color causing the shadow around the display to minimize.

9. The method of claim 8 , further comprising:

in response to the display being in an off state:

causing, by the light source, the color-changing material to change from the second color to the first color, the light source in an unilluminated state.

10. The method of claim 8 , wherein the color-changing material is comprised of a photochromic pigment.

11. The method of claim 10 , wherein causing the color-changing material to change from the first color to the second color comprises:

absorbing, by the photochromic pigment, the one or more wavelengths of light; and

causing, by the photochromic pigment, a photochemical reaction within the mold frame.

12. The method of claim 8 , wherein the first color is black.

13. The method of claim 8 , wherein the second color is grey.

14. An information handling system, comprising:

at least one processor; and

a display including:

a light source; and

a mold frame configured to minimize a shadow around the display, the mold frame comprising:

an outer portion configured to couple the mold frame to an exterior portion of a cover bottom of the display;

a middle portion including an adhesive portion configured to couple the mold frame to a panel of the display; and

an inner portion configured to contact an interior portion of the cover bottom, the inner portion including a color-changing material causing the inner portion to change from a first color to a second color, the first color causing the shadow around the display, the second color causing the shadow around the display to minimize.

15. The information handling system of claim 14 , wherein the color-changing material is comprised of a photochromic pigment.

16. The information handling system of claim 15 , wherein causing the inner portion to change from the first color to the second color comprises:

absorbing, by the photochromic pigment, one or more wavelengths of light emitted by the light source of the display; and

causing, by the photochromic pigment, a photochemical reaction within the mold frame.

17. The information handling system of claim 14 , wherein the mold frame is within a field of view of a user via the panel of the display.

18. The information handling system of claim 14 , wherein the mold frame further comprises:

a reflector coupled to the cover bottom of the display, the reflector including:

a covering portion coupled to the inner portion of the mold frame, the covering portion having the second color causing the shadow around the display to minimize; and

a folding portion coupling the reflector to the covering portion.

19. The information handling system of claim 14 , wherein the first color is black.

20. The information handling system of claim 14 , wherein the second color is grey.
