Abstract:
1. A display apparatus comprising: a display panel which displays an image; a printed circuit board comprising a control circuit which outputs image data, a data control signal and a gate control signal; a data driver comprising a digital processor and an analog processor, and which receives the image data and the data control signal to provide the display panel with a data signal; and a gate driver which receives the gate control signal to provide the display panel with a gate signal, wherein the printed circuit board comprises: a first voltage interconnection which supplies a first source supply voltage to the digital processor of the data driver; and a second voltage interconnection electrically isolated from the first voltage interconnection and which supplies a second source supply voltage to the analog processor of the data driver, wherein the printed circuit board comprises a multilayer structure, the first voltage interconnection is disposed on a first layer of the multilayer structure, and the second voltage interconnection is disposed on second layer different from the first layer, of the multilayer structure.
