Abstract: An electronic device is provided. The electronic device includes a sensing element and a display panel. The display panel has a first region and a second region adjacent to the first region. The sensing element is disposed corresponding to the first region and configured to receive a light through the first region. In addition, the display panel includes a plurality of first light absorbing patterns and a plurality of second light absorbing patterns disposed in the second region. The plurality of first light absorbing patterns and the plurality of second light absorbing patterns are configured to absorb different colors of lights. An area of one of the plurality of first light absorbing patterns is different from an area of one of the plurality of second light absorbing patterns.

Abstract: A display panel is provided. The display panel has a display region and a non-display region. The non-display region has an aperture region and a non-aperture region surrounding the aperture region. The display panel includes a plurality of light-emitting elements disposed in the display region. The display panel includes a plurality of first light absorbing patterns and a plurality of second light absorbing patterns disposed in the non-aperture region. The plurality of first light absorbing patterns and the plurality of second light absorbing patterns are configured to absorb different colors of lights.

Abstract: A warhead includes a body, a patterned liner made of plastic, and an explosive charge disposed within the liner. The liner pattern is formed of gaps and liner elements. The explosive charge includes a first set of sections that are disposed adjacent to the liner gaps and a second set of sections that are disposed adjacent to the liner elements. Upon detonation of the explosive charge and because of the temporal delay in transmitting the detonation energy between these two sets of sections, the warhead body is caused to shear and break into fragments with controlled size. The use of plastic as the liner material also provides a welcome safety feature for this warhead. In the event of unwanted heat ignition, the plastic (which is also low melt temperature material), would melt to seal the explosive and would also flow. Because of the plastic, neither sudden pressure nor heat/ignition inside the round, would therefore be as catastrophic.
