An image display device employs an interface protocol wherein integrated image plus control data is transmitted from a signal controller circuit to each of a plurality of master data driving circuits. The integrated image plus control data includes display control data as well as image-defining data. The signal controller circuit determines which of a plurality of data driving circuits is to function as a master data driving chip and which as a slave data driving chip. The signal controller circuit directly transmits respective integrated image plus control data signals to corresponding ones of the master data driving chips. Each master data driving chip then forwards part of the received integrated image plus control signal to its corresponding slave data driving chip.

摘要:
A method for driving a display apparatus, according to one or more embodiments of the present invention, provides a luminance representative value of a unit light-emitting block that may be determined from an external image signal of a plurality of image blocks corresponding to the unit light-emitting block including a plurality of light sources. A luminance compensation value of the unit light-emitting block may be calculated by compensating the luminance representative value. Pixel data of the external image signal in a central area of the unit light-emitting block and a boundary area may be corrected based on the luminance compensation value. A driving signal may be provided to the unit light-emitting block based on the luminance compensation value. Accordingly, a phenomenon in which a boundary of the unit light-emitting block is visible is removed so that the display quality of all image may be enhanced.
