New Description: [New Technology Field] This creation is related to the structure of optical displays, and more specifically refers to a flexible display panel used in e-books. 5 [Prior Art] The first and second figures reveal a common e-book structure, which has a display panel 1, a thin film flip chip board 2 and a PCB circuit board 3, which are mutually privately connected. The substrate 4 is disposed on a substrate 4, and a protective film 6 is disposed on the substrate 4, wherein the substrate 4 is disposed on a glass plate 4a with a plurality of substrates of the thin film transistors 4b. The layer 5 comprises a plurality of positive/negative black/white particles 5a, 5b which are driven by an applied electric field provided by the film flip chip board 2 to change the position, thereby generating a preset display effect. The PCB circuit board 3 provides a start signal to the thin film flip chip board 5. 15 Although the above-mentioned e-book structure is portable and easy to carry, the base 4 of the display panel 1 is made of a hard glass plate which cannot be bent arbitrarily, and is easily inadvertently collided or squeezed in use. Secondly, please refer to the third figure. When making the e-book, ^I surely combine the pin 2a of the film flip-chip 2 with the ιτ〇 electrode 仏2〇 of the substrate 4, and ensure each other. It has good electrical conductivity and uses anisotropic conductive film (ACF) 7 as the intermediate electrical connection. However, the use of the anisotropic conductive adhesive 7 as a joint is used. #乂 is cumbersome, and its selling price is too high to reduce the production cost of e-books; for this reason, the creators of this case hope to improve the aforementioned shortcomings, which is based on 4 M347682 years of development experience. [New content] The main purpose of this work is to provide a soft-feeling feature: the display panel, its nature. ❿It is not easy to be damaged by squeezing, and it is convenient to make it for use. The second purpose is to provide a kind of flexible display panel. The second anti-plate and the soft printed circuit board on the bottom layer of the recording display board, the ft layer, the electronic ink thin layer is disposed on the soft printed Jf ^ ^ ^ ^ 匕 containing the number of positive / negative electric particles, these The particle 15 20 crystal circuit board provides an external electric field to change the position, so as to produce a display effect.
