Embodiment approach 1

[0127] Next, a display module according to this embodiment will be described with reference to FIGS. 1A and 1B and FIG. 2 . 1A and 1B, and FIG. 2 are diagrams showing the configuration of a display module according to the present embodiment. 1A and 1B are cross-sectional views of a display module, wherein FIG. 1A is a cross-sectional view of display panels arranged on the same plane, and FIG. 1B is a cross-sectional view of display panels arranged in a back-to-back manner. Fig. 2 is a top view of the display module viewed from one direction. Note that the display modes shown in Figures 1A and 1B

[0128] The blocks differ only in the way the display panels are arranged, and therefore share the same reference numerals.

[0129] The display module shown in FIGS. 1A and 1B has a first display panel 102 , a second display panel 104 , and a signal processing circuit substrate 106 . The first display panel 102 and the second display panel 104 have different surfaces for displayin...

Abstract

To reduce the number of components such as IC chips so that decrease in size and thickness of a display module and an electronic device on which the display module is mounted is achieved. Further, to reduce the number of components such as IC chips so that an inexpensive display module and an electronic device on which the display module is mounted are provided. An electronic device or a display module includes two display panels. One of the display panels (i.e., a peripheral portion of a display region of the one of the display panels) is provided with circuits which are necessary for operating the display panels or circuits which are necessary for an electronic device in which the display panels are incorporated. Then, the display panels or the electronic device in which the display panels are incorporated are / is driven by the circuits incorporated in the display panels.

Description

technical field [0001] The present invention relates to articles, methods, or methods of producing articles. In particular, the present invention relates to a display device or a semiconductor device. Background technique [0002] A liquid crystal display module that displays an image by using a liquid crystal panel is used in an image display portion of an electronic product such as a mobile phone. In addition, practical use of a display module using an organic electroluminescent (organic EL) panel instead of a liquid crystal panel is also promoted. [0003] The display module is formed by connecting a display panel composed of liquid crystal or organic EL elements and a circuit substrate mounted with a driver IC or a power supply IC using a flexible wiring board. As the flexible wiring board, a wiring pattern is formed on a resin film, and a flexible wiring board on which a driver IC is directly mounted can also be used. [0004] In recent years, electronic products suc...
