Abstract: A display device with a switchable viewing angle includes a timing controller to generate an image data, a data control signal, and a gate control signal, a data driver to generate a data signal using the image data and the data control signal, a gate driver to generate a gate signal and first to third emission signals using the gate control signal, and a display panel including a plurality of subpixels to display an image using the data signal, the gate signal, and the first to third emission signals. The gate driver includes a gate signal generator to generate the gate signal, first emission signal generator to generate the first emission signal, and second and third emission signal generators to generate the second and third emission signals, respectively, using input and output signals of the gate signal generator and input and output signals of the first emission signal generator.

Abstract: A viewing angle switchable display device can include a display panel including first, second, and third sub-pixels, each of the first, second, and third sub-pixels having a first emission area and a second emission area spaced apart from the first emission area; and a lens layer disposed over the display panel and including a first type of lens corresponding to the first emission area and a second type of lens corresponding to the second emission area, in which the first type of lens has a different shape than the second type of lens. Also, the display panel is configured to display an image according to a wide view mode via the first emission area and the first type of lens, and display the image according to a narrow view mode via the second emission area and the second type of lens.
