Abstract: A display device with a built-in touch screen according to the present disclosure includes a display panel, a data driver, a gate driver, a touch sensing unit, a common voltage supplier, and a switch circuit, and further includes a common voltage adjuster to supply different common voltages to touch electrodes of the display panel, thereby resolving a local stain or screen vibration problem occurring on the display panel. Further, a method for driving a display device with a built-in touch screen according to one embodiment includes: switching the display panel from a touch mode to a display mode, generating different common voltages, and supplying two or more of the different common voltages to a plurality of touch electrodes (TE) or groups of touch electrodes (TE), thereby resolving an image quality defect.

Abstract: A display panel and a display apparatus are provided, in which a ratio of a plurality of areas capable of independently controlling a viewing angle in a display area may be adjusted. The display panel includes pixel blocks including subpixels and multiplexer circuits disposed in a bezel area and individually connected to the pixel blocks. The multiplexer circuits supplies first and second mode control signals to any one of the pixel blocks. The subpixels include a first light-emitting element connected to a driving transistor through a first mode control transistor controlled by the first mode control signal, a second light-emitting element connected to the driving transistor through a second mode control transistor controlled by the second mode control signal, a first lens area disposed on the first light-emitting element, and a second lens area disposed on the second light-emitting element.
