Abstract:
Provided is a backlight device, wherein when the drive duty and drive current are controlled in each of predetermined light-emitting areas of a light-emitting unit, the color unevenness and moving image resolution difference between image display areas corresponding thereto are improved. A light-emitting unit (121) comprises a plurality of light-emitting areas. A motion amount detecting unit (131) detects the motion amount of an image in each of image display areas. A drive condition specifying unit specifies, with respect to each of the plurality of light-emitting areas, a drive condition including the duty and pulse height value of a drive pulse for causing each of the plurality of light-emitting areas to emit light, on the basis of the detected motion amount. An LED driver (123) drives each of the plurality of light-emitting areas on the specified drive condition. When a difference between the detected motion amounts occurs between adjacent image display areas, the drive condition specifying unit adjusts the drive conditions such that a difference between the drive conditions occurring between adjacent light-emitting areas is reduced according to the difference between the detected motion amounts.

A light-emitting device includes a light-emitting element 110; and a lens section 132 covering over the light-emitting element 110. The lens section 132 includes an entrance surface S1 on which light from the light-emitting element 110 is incident; an exit surface S2 from which the light incident on the entrance surface S1 is emitted; and an optical axis L extending so as to penetrate the entrance surface S1 and the exit surface S2. A concave section 132a is formed in an area of the exit surface S2, which contains the optical axis L, and two flat sections 132b are formed so as to face each other across the optical axis L. The exit surface S2 defines an upwardly-protruding curved surface formed between the two flat sections 132b, and the optical axis L is coincidence with a reference optical axis of the light-emitting element 110.

Abstract:
A client connected to a communication network performs an access request to an object. An application server performs an application by an actual object according to the client request. An object pool connected to the client and the application server pools a proxy object corresponding to the actual object and holds the actual object management information. The application server notifies the object pool of an event according to the status change of the application. The object pool automatically updates the actual object management information according to the notification of the event from the application server.
