An organic electroluminescence device and display having high efficiency and improved durability. The sensor array uses a first polysilicon and the core logic uses a second polysilicon. The method of forming the metal coating of the present invention includes the steps of cladding a surface of the substrate with metal powder by a laser cladding method and forming the metal coating having a microstructure by applying a friction stir processing to the cladded region. The profile can be created from the system being tested by playing the prompts to the recognizer in a training operation in an order controlled by a training script that allows the recognizer to be exposed to enough words spoken by the talent to train the recognizer to recognize the voice of the talent. During grinding, the glass sheet is no longer supported and moved by the conveyor but by at least one carriage, to which the glass sheet is coupled by way of at least one sucker. The bottom surface of the label has a nonskid material such as varnish applied thereto.
