1. A touch key assembly comprising:
a light guiding film between a window and a display panel;
a flexible printed circuit (FPC) film attached to the light guiding film; and
an attaching member comprising an attaching portion interposed between the light guiding film and the window, and a blocking portion interposed between the window and the display panel.
2. The touch key assembly of claim 1, wherein the attaching portion and the blocking portion are integrally formed.
3. The touch key assembly of claim 1, wherein the blocking portion has a black color for reducing leakage of light from the light guiding film.
4. The touch key assembly of claim 1, wherein the blocking portion has a thickness greater than that of the attaching portion.
5. The touch key assembly of claim 1, wherein the attaching member comprises a double-sided tape.
6. A display device comprising:
a display panel;
a window facing the display panel, the window having a display region and a non-display region;
a touch key comprising a light guiding film between the non-display region of the window and the display panel, and a flexible printed circuit (FPC) film attached to the light guiding film; and
an attaching member comprising an attaching portion interposed between the light guiding film and the window and a blocking portion interposed between the window and the display panel.
7. The display device of claim 6, wherein the blocking portion is configured to isolate the touch key from a region where a resin configured to attach the display panel to the window is coated to reduce infiltration of the resin into the touch key.
8. The display device of claim 7, wherein the blocking portion has a thickness substantially the same as a gap between the display panel and the window.
9. The display device of claim 6, wherein the display panel comprises an organic light emitting display (OLED) panel.
10. A method of assembling a display device, the method comprising:
attaching an attaching member comprising an attaching portion and a blocking portion to a window;
attaching a touch key to the attaching portion; and
attaching a display panel to the blocking portion.
11. The method of claim 10, further comprising attaching the display panel to the window using a resin,
wherein the blocking portion is configured to block the resin to reduce infiltration of the resin into a touch key during attaching of the display panel to the window.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for detecting a microorganism in a sample, comprising:
combining the sample with at least one substrate such that an enzyme of the microorganism can react with the at least one substrate to produce a biological molecule;
providing a partitioning element that allows partitioning of substantially only the at least one substrate or the biological molecule thereinto in accordance with a partitioning constant (Kfs); and
detecting fluorescence of the at least one substrate or the biological molecule in the partitioning element;
wherein the detected fluorescence indicates the microorganism is present in the sample.
2. The method of claim 1, wherein the partitioning element comprises a polymer.
3. (canceled)
4. The method of claim 1, wherein the detecting fluorescence comprises detecting a change in amount of fluorescence.
5-6. (canceled)
7. The method of claim 1, wherein the microorganism is a biological contaminant.
8. The method of claim 1, wherein the at least one enzyme is selected from \u03b2-glucuronidase and \u03b2-galactosidase.
9. The method of claim 7, wherein the microorganism is selected from E. coli and total coliform.
10. The method of claim 1, wherein the at least one substrate is selected from pyrene-\u03b2-D-glucuronide, anthracene-\u03b2-D-glucuronide, pyrromethene-\u03b2-D-glucuronide, pyrene-\u03b2-D-galactopyranoside, and anthracene-\u03b2-D-galactopyranoside.
11. The method of claim 1, wherein the sample is selected from water, a biological sample, food, and soil.
12. The method of claim 1, further comprising combining the sample and the at least one substrate in a cartridge comprising the partitioning element.
13-14. (canceled)
15. The method of claim 2, wherein the partitioning element comprises a hydrophobic polymer.
16. The method of claim 2, wherein the polymer comprises polydimethylsiloxane (PDMS).
17-48. (canceled)
49. The method of claim 1, further comprising using an excitation light source to irradiate the biological molecule or the at least one substrate partitioned into the partitioning element.
50. The method of claim 1, wherein the partitioning element allows partitioning of substantially only the biological molecule thereinto.
51. The method of claim 1, wherein Kfs is greater than one.
52. The method of claim 11, wherein the sample is a water sample.
