Problems solved by technology

[0026] In other words, for a small display, cost reduction can be achieved, but for a large or high-resolution display, since the wiring of the control signal from the semiconductor element for driving the display increases, it is necessary to increase the carrier tape. As a result, the cost increases and the effect of cost reduction cannot be obtained

Abstract

Provided is a drive device, display panel module, display device and method for manufacturing a drive device, which make it possible to reduce the number of drive circuit elements without reducing the number of display panels to be taken out, and without increasing interconnection regions on a film. Specifically, provided is a drive device which is provided with a film (1), on which interconnections (4) and a circuit element (2) are mounted, and drives a display panel. The drive device is provided with a first film portion (1a) and second film portion (1b) in the film (1) which are separated from each other by an incision (9) made therein, and each of the first and second film portions (1a and 1b) is connected to the display panel while having been folded at least once.

Description

technical field [0001] The present invention relates to a driving device (display driving device) mounted on a display screen such as a liquid crystal panel or an organic electroluminescent screen, a display module using the driving device, a display device, and a method for manufacturing the driving device. Background technique [0002] In recent years, display devices mounted on display devices have gradually shifted from devices using cathode ray tubes to devices using liquid crystal panels (display screens), which have low power consumption. And save space and other advantages. [0003] However, at present, the price of an LCD screen is about several times that of a cathode ray tube. In order to further expand the market for LCD screens, it is essential to reduce the cost of LCD screens and peripheral equipment. [0004] As the size of the display screen progresses, the Figure 15A In the shown display device, the number of semiconductor devices 54 used increases, and a...
