A foldable display device includes a shell. The shell has an expanding state and a folding state. A first direction and a second direction are defined to be orthogonal. When the shell is at the expanding state, the shell has a first length Lalong the first direction and a second length Lalong the second direction. The ratio of the first length Lto the second length Lis between 1.3 and 2. When the shell is at the folding state, the shell has a third length Lalong the second direction and a fourth length Lalong the first direction. The ratio of the third length Lto the fourth length Lis also between 1.3 and 2.

Foldable display device

A flexible display panel has an active region and a peripheral region surrounding the active region. The flexible display panel includes a barrier layer, a flexible layer, a display device array and a driving IC. The barrier layer has a first opening. The flexible layer is disposed on the barrier layer, and filled into the first opening of the barrier layer. The display device array is disposed on the flexible layer and located in the active region. The driving IC is disposed on the flexible layer, electrically connected to the display device array and corresponding to the first opening of the barrier layer.

Flexible display panel and method of fabricating flexible display panel

A foldable display device includes a shell. The shell has an expanding state and a folding state. A first direction and a second direction are defined to be orthogonal. When the shell is at the expanding state, the shell has a first length L1 along the first direction and a second length L2 along the second direction. The ratio of the first length L1 to the second length L2 is between 1.3 and 2. When the shell is at the folding state, the shell has a third length L3 along the second direction and a fourth length L4 along the first direction. The ratio of the third length L3 to the fourth length L4 is also between 1.3 and 2.

A flexible display has a display layer, a thin-film transistor (TFT) layer and a flexible substrate. The display layer has a plurality of display units. The TFT layer has a plurality of pixel control circuits and a plurality of sensing circuits. The pixel control circuits are configured to control operations of the plurality of display units. Each of the sensing circuits is configured to generate a deformation signal according to deformation of the flexible display. The flexible substrate and the TFT layer are stacked.
