A display device with switchable viewing angle includes a display panel, a backlight source, a timing controller, a source driver chip and an LED driver module. The backlight source includes a plurality of LEDs. The timing controller is connected to the source driver chip. The source driver chip is connected to the plurality of data lines. The LED driver module is connected to the plurality of LEDs. The display panel has a narrow viewing angle mode and a wide viewing angle mode. In the narrow viewing angle mode, the luminous brightness of the plurality of LEDs is adjusted to gradually decrease from the middle to both sides of the display panel. In the wide viewing angle mode, the luminous brightness of the plurality of LED is adjusted to gradually increase from the middle to both sides of the display panel.

Display device with switchable viewing angles

A touch display device includes a first substrate, a second substrate opposite to the first substrate, a display medium sandwiched between the two substrates, and a touch-sensitive layer including sensitive electrode lines. The first substrate includes a first surface facing the display medium layer and a second surface far away from the display medium layer and opposite to the first surface. The touch-sensitive layer is disposed on the second surface of the first substrate, and first pins are disposed on a side area of the first substrate corresponding to a side of the touch display device to connect the sensitive electrode lines. Second pins are disposed on a side area of the second substrate corresponding to the same side of the touch display device, and connected to the first pins via a first printed circuit board (PCB). The first PCB is a flexible PCB.
