Problems solved by technology

Therefore, there is a problem that a large-sized antenna is required depending on the performance required for the antenna, and the miniaturization of the entire device cannot be achieved.
[0004] In addition, in the traditional method, the antenna is for the purpose of information input, in order to maintain the display and display functions of the LCD and so on, the minimum auxiliary equipment is required, for example, in the In the case of a transmissive LCD, it is necessary to supply all the power for driving the LCD itself and the backlight LEDs other than it, and it is difficult to realize a display device without a connection line to the host computer at all.

Embodiment Construction

[0043] Regarding the embodiment of the present invention, according to figure 1 ~ Fig. 7 for the following description.

[0044] (shows the structure of the system)

[0045] figure 2 The structure of the display system 100 of this embodiment is shown. As shown in the figure, the display system 100 is configured to include a drive device (transmission-side device) 50 and a wireless display device (reception-side device, liquid crystal display unit) 90 . In this configuration, signals such as video signals and control / timing signals are wirelessly transmitted from the drive device 50 to the wireless display device 90 . Further, the driving device 50 supplies power to the wireless display device 90 by wireless power feeding using electromagnetic induction or resonance (resonance) type wireless power feeding. Resonance-type wireless power feeding is a technique in which the resonance frequencies of the antennas on the transmitting side and the receiving side are set to the sa...

Abstract

The invention relates to an antenna device, a display device substrate, a liquid crystal display unit, a display system, a method for manufacturing the antenna device, and a method for manufacturing the display device substrate. An antenna (81) and an electrical wiring for connecting the antenna (81) and a receiving section (82) are monolithically formed on an active matrix substrate by a thin film process to obtain the antenna device. The electrical conductivity of a material constituting the antenna (81) is higher than that of a material constituting the electrical wiring.

Description

technical field [0001] The present invention relates to an antenna device for transmitting signals and electric power, a display device substrate using the antenna device, a liquid crystal display unit, and a display system. Furthermore, it relates to a method of manufacturing the aforementioned antenna device and a method of manufacturing the aforementioned display device substrate. Background technique [0002] Conventionally, there have been proposals for antennas used in small portable devices having a display unit composed of an LCD (Liquid Crystal Display) to realize miniaturization by using a reflector of the LCD or constituting the antenna with electrodes sandwiching a liquid crystal material. A method of chemicalization (refer to Patent Document 1). In addition, a method of realizing miniaturization by constituting an antenna using data signal lines and scanning signal lines of the LCD is also proposed (see Patent Document 2). That is, conventionally, miniaturizat...
