Abstract: A backlight unit includes a light source having a plurality of light-emitting units that emit light in at least three different colors, a light guide plate having N preset regions, where N is a positive integer, and a backlight control unit controlling the light-emitting units to provide light to the N preset regions. The light guide plate has a light incidence side, and the light source is disposed opposite to the light incidence side. The light emitted by the light source spreads in the preset regions. The backlight control unit acquires image data information corresponding to the preset regions, and derives chrominance and luminance information of the image corresponding to the preset regions, by calculating the acquired image data information. The backlight control unit then, based on the chrominance and luminance information of the preset regions, controls the light-emitting units to provide light to the preset regions.

Abstract: A method for distributing virtual items includes receiving, from a sender client device, a request for distributing virtual items to a set of recipient client devices. The method includes transferring a total amount of virtual items from an account associated with the sender client device to an account associated with a server device, and defining virtual item packages that include the total amount of virtual items transferred. The method includes sending information of the virtual item packages to the sender client device whereby the sender client device generates and sends a link associated with the distribution of virtual items to the set of recipient client devices. The method also includes receiving, from a recipient client device, a request to receive virtual items. The method further includes transferring a virtual item package from the account associated with the server device to an account associated with the recipient client device.
