Description

Flexible tactile diode display

The present invention relates to a light-emitting diode display, and more particularly to a flexible light-emitting diode display.

In recent years, flexible displays that are lightweight and resistant to vibration have been developed, and are made of materials such as plastic. Since such a flexible display can be folded or rolled up, its portability is maximized. At the same time, such a flexible display can be applied to various fields, such as electronic billboards, window advertisements, bulletin boards of exhibition venues, and the like.

A conventional flexible display includes a display element formed on a flexible substrate. Among them, various types of display elements can be used in the flexible display, including an organic light emitting diode display device, a liquid crystal display device, an electrophoretic display (EPD) device, and the like. These types of display devices typically comprise a thin film transistor. Thus, to form a flexible display, the flexible substrate undergoes a number of thin film processes to form a thin film transistor. However, since the flexible substrate is generally relatively thin, about several tens of micrometers, it is difficult to perform several thin film processes separately on the flexible substrate. Currently there is A method in which a flexible substrate is first formed on a glass substrate, a display element is formed on the flexible substrate, adhered to the glass substrate, and then the flexible substrate and the glass substrate are bonded to each other. Separately, the method is used to carry out the film process. A flexible substrate made of a plastic material typically has a different coefficient of thermal expansion (CTE) than the glass substrate. If the adhesion between the flexible substrate and the glass substrate is weak, the flexible substrate may be peeled off from the glass substrate and separated, or partially removed and bent during a high temperature process, which is flexible A fatal flaw can be caused in the process of the display. In addition, the current single-layer or double-layer transparent flexible LED display is limited to the use of single-color (double-pin) LEDs due to limited circuit design, and full-color LEDs cannot be used to provide full-color display. The application of the display is still not universal.

In view of this, a full-color flexible display that is convenient in processing and can overcome the above disadvantages is highly anticipated by the industry. Therefore, the creation of the full-color LED can be applied to the transparent flexible substrate by utilizing the flexible circuit design on the transparent flexible substrate and the change of the position of the pin on the back of the full-color LED, which can not only solve the complexity of the full-color LED display. Line problems, and can be applied to single or double transparent transparent substrates, providing a high-density full-color LED display.
