Problems solved by technology

However, since the flexible substrate of the flexible display panel will still experience different process temperature changes during the bonding process of the driver chip and the flexible display panel or other subsequent processes, the flexible substrate may be damaged due to expansion. Or contraction affects the electrical contact between the driver chip and the flexible display panel, or affects the electrical contact between the flexible circuit board and the flexible display panel

Embodiment Construction

[0033] Figure 1A to Figure 1E It is a schematic top view of the process flow of a manufacturing method of a flexible display according to an embodiment of the present invention, and Figure 2A to Figure 2E respectively along Figure 1A to Figure 1E A schematic cross-sectional view of line A-A'. Please also refer to Figure 1A and Figure 2A , firstly, a flexible display panel 110 is formed on a hard substrate 102, the flexible display panel 110 has a display area 112, a driver chip bonding area 114 outside the display area 112 and a flexible circuit Landing area 116. In this embodiment, the hard carrier 102 is, for example, a hard material substrate such as a glass substrate, a quartz substrate, or a silicon substrate. The flexible display panel 110 includes a flexible substrate 111 and a display unit 113. The flexible substrate 111 is, for example, a plastic substrate with good flexibility. The flexible substrate 111 of the flexible display panel 110 is attached to Attac...

Abstract

The invention relates to a flexible display, comprising a flexible display panel, a driving chip and a shrinkage restrain construction member, wherein, the flexible display panel is provided with a display area and a driving chip bonding land positioned outside the display area; the driving chip is electrically connected with the driving chip bonding land; the shrinkage restrain construction member is configured at the periphery of the driving chip bonding land; the rigidity of the shrinkage restrain construction member is higher than that of the flexible display panel, and the coefficient ofthermal expansion of the shrinkage restrain construction member is lower than that of the flexible display panel, thus the shrinkage restrain construction member can restrain the shrinkage amount of the flexible display panel, thereby avoiding the condition that the flexible display panel shrinks by a large margin when the temperature changes; and the flexible display of the invention can ensure the condition that the flexible display panel is electrically connected with the driving chip.

Description

technical field [0001] The invention relates to a display and a manufacturing method thereof, in particular to a flexible display and a manufacturing method thereof. Background technique [0002] With the rapid development of display technology, the display has gradually developed from the early cathode ray tube (CRT) display to the current flat panel display (Flat Panel Display, FPD). Compared with flat-panel displays composed of rigid substrates (such as glass substrates), since flexible substrates (such as plastic substrates) have the characteristics of flexibility and impact resistance, research has been carried out in recent years on the fabrication of active components in flexible substrates. Flexible displays on flexible substrates. [0003] Generally speaking, if an active component is to be fabricated on a flexible substrate, the flexible substrate needs to be adhered to a rigid carrier first, and then a series of film-forming processes are performed to fabricate a...
