Abstract

The invention relates to an electrophoretic display and a manufacturing method thereof. The electrophoretic display comprises a first base plate, an active component array, a driving circuit, a flexible printed circuit, an electrophoretic display layer, a second base plate and a driving chip. The first base plate is provided with a first surface which is provided with a display region and a line region. The active component array is arranged in the display region, the driving circuit is arranged in the line region and is electrically connected to the active component array, and an electric conduction flexible circuit is partially arranged on the first base plate and is electrically connected to the driving circuit. The electrophoretic display layer and the second base plate are arranged on the active component array and the driving circuit sequentially, and the sealing compound is adhered between the second base plate and the electric conduction flexible circuit to tightly seal the electrophoretic display layer between the first base plate and the second base plate. The driving chip is connected with the diving circuit, and the electrophoretic display layer comprises an opening to expose the driving chip. The invention also discloses a manufacturing method of the electrophoretic display.

Description

technical field

[0001] The invention relates to a display and a manufacturing method thereof, in particular to an electrophoretic display and a manufacturing method thereof. Background technique

[0002] With the advancement of flat panel display technology, more and more electronic products are equipped with displays, especially portable electrical products, such as mobile phones, e-books, digital Camera (digital camera) and personal digital assistant (personal digital assistant, PDA), etc. Since portable electronic products tend to be light in weight and thin in thickness, displays used in portable electronic products also need to have the advantages of light in weight and thin in thickness.

[0003] Based on the above, since flexible displays not only have the advantages of light weight and thin thickness, but also have the advantages of being flexible and unbreakable, the manufacture of flexible displays has become an important development trend. At present, the common...
