EXAMPLES

[0101] The following examples are examples of reflective displays before and after being incorporated into laminated glass articles according to the present disclosure. While the examples describe laminated glass, it is understood that the reflective displays may be utilized to other glass articles, such as architectural glass.

[0102] The examples include samples that were tested under accelerated conditions to UV, temperature, and humidity. Five samples were prototyped and tested for aesthetics. All other samples were made without a painted portion in order to better detect failures.

TABLE-US-00001 TABLE 1 Unlaminated L* a* b* Black 16 0.22 4.1 White 72 2.4 0.81

TABLE-US-00002 TABLE 2 Laminated L* a* b* Black 13 0.87 3.2 White 53 2.0 1.3

[0103] The graph of FIG. 8 illustrates reflectivity of laminated and non-laminated reflective displays. TABLES 1 and 2 show results recorded. The contrast ratio measurements were calculated from L* values converted to reflectivity. The clear soda lime glass used in the first glass substrate 210 and the second glass substrate 220 absorbed a portion of light prior to hitting the display 160 and again absorbed a portion of the reflected light. It is noted that glass reflectivity also contributes to removing a portion of light. Typical L*a*b* prior to lamination are: Black: 16, 0.22, 4.1 and White: 72, 2.4, 0.81.

Typical L*a*b* after lamination are: Black: 13, 0.87, 3.2 and White: 53, 2.0, 1.3. The recorded data shows that the contrast ratio decreased from 20.6 to 13.3 when the display is positioned in a laminated glass article, which is still within a desired range.

[0104] For temperature testing, 8 samples were tested in various temperature conditions ranging from 85 C. to 30 C. For hot storage durability, samples were heated to 85 C. for about 20 hours, returned to ambient temperature, about 23 C., for 4 hours, then evaluated for optical and appearance within an hour. Testing was repeated for four cycles. For cold storage durability, samples were cooled to 30 C. for about 20 hours, returned to ambient temperature, about 23 C., for 4 hours, then evaluated for optical and appearance within an hour. Testing was repeated for four cycles. For temperature cycling, samples were heated to 85 C. for about 20 hours, returned to ambient temperature, about 23 C., for 4 hours, then evaluated for optical and appearance within an hour, then cooled to 30 C. for about 20 hours, returned to ambient temperature, about 23 C., for 4 hours, then evaluated for optical and appearance within an hour. Testing was repeated for two cycles. Overall, as illustrated in FIGS. 9-11, contrast ratios remained within margin of error across all samples. Further, L*, a*, and b* values before and after testing can be seen in TABLES 3-5.

[0105] Delta E was documented throughout experimentation as well, see FIGS. 12 and 13. Apart from laminating the display into glass, the delta E was below 1 for all measured samples, within the performance requirements of less than 3. Deltas were derived by taking the pre-test L*a*b* and the L*a*b* at a given point during testing using the CIE76 formula. For humidity testing, samples were visually inspected for degradation. No degradation issues were observed for the 8 samples tested.

[0106] Accordingly, as shown in the tables above and in FIGS. 8-13, the contrast ratio of the samples met the requirements of >8, the samples passed hot and cold storage testing, and the samples passed temperature cycle testing.

[0107] It will be readily appreciated by those skilled in the art that modifications may be made to the disclosure without departing from the concepts disclosed in the foregoing description. Accordingly, the particular examples described in detail herein are illustrative only and are not limiting to the scope of the disclosure, which is to be given the full breadth of the appended claims and any and all equivalents thereof.
