Abstract:
In a method of detecting inhomogeneity of a layer, an incident light may be irradiated to at least two regions of the layer at a first incident angle position. First reflected lights reflected from the two regions of the layer may be sensed. The incident light may be irradiated to the at least two regions of the layer at a second incident angle position. Second reflected lights reflected from the two regions of the layer may be sensed. The first reflected lights and the second reflected lights may be compared with each other to obtain the inhomogeneity of the layer. Thus, the layer having a spot may be found.
Abstract:
An apparatus for testing electronic devices may include a test chamber, a heating unit, a cooling unit and a controller. The test chamber may include a plurality of slots configured to receive the electronic devices. The heating unit may heat the electronic devices in the slots. The cooling unit may individually cool the electronic devices in the slots. The controller may selectively control operations of the heating unit and the cooling unit in accordance with temperatures in the slots. Thus, the electronic devices may be provided with a uniform test temperature so that reliability of test results may be improved.

Abstract:
An apparatus and method for displaying an image in a mobile terminal are provided. One or more images are selected from among a plurality of pre-stored images, based on information about a party other than the user of the mobile terminal, stored in a phone book, and information about an event that is currently executed in the mobile terminal, and the selected images are preferentially displayed.
Abstract:
A method for displaying an image is provided, the method including: displaying, on a touchscreen of an electronic device, a plurality of items; selecting a first item from the plurality in response to an input received at the electronic device; detecting whether a condition for displaying an auxiliary area is satisfied; and responsive to the condition being satisfied, displaying the auxiliary area on the touchscreen.
