Problems solved by technology

[0005] However, when a flexible substrate with a different orientation is bent and twisted to align the orientation of the flexible substrate with that of another flexible substrate and reverse the front and back of the electrode surface, stress in the twisted direction is applied to the flexible substrate. , there is a problem that the flexible substrate is broken (specifically, the wiring formed on the flexible substrate is broken)

Embodiment approach

[0035] figure 1 It is a diagram schematically showing a schematic configuration of the projector 1 according to the present embodiment.

[0036] The projector 1 of the present embodiment includes: an exterior case 2 constituting the exterior; a projection lens 3 as projection optical means; an optical unit 4 , and the like. The optical unit 4 includes three reflective light modulation devices 52 ( 52R, 52G, and 52B) corresponding to the respective colors of red (R) light, green (G) light, and blue (B) light. The projector 1 modulates the light beams emitted from the light source device 100 by using the reflective light modulation devices 52R, 52G, and 52B according to the image signal to generate an optical image, and synthesizes the optical image by using the color synthesis optical device 400, and synthesizes The image light is enlarged and projected on the screen SC and so on.

Abstract

A substrate connection structure between a plurality of light modulating devices each having a flexible substrate extending in a predetermined direction and a circuit substrate connected with the light modulating devices, wherein the light modulating devices are arranged so that the direction of one flexible substrate extending from at least one of the light modulating devices is different from the directions of the other flexible substrates extending from the other light modulating devices, the substrate connection structure includes: a relay substrate which is connected with the one flexible substrate; and an extension flexible substrate which is connected with the relay substrate.

Description

technical field [0001] The present invention relates to a substrate connection structure and a projector provided with the substrate connection structure. Background technique [0002] Conventionally, there is known a projector that separates a light beam emitted from a light source into three color lights, modulates each of the separated color lights by a light modulation device, and uses a color synthesizing optical device to analyze the light beams emitted from each light modulation device. The optical images are synthesized, and the synthesized optical images are projected as image light. In addition, the light modulation device has a flexible substrate, and is connected to a drive circuit substrate for driving the light modulation device. [0003] Here, when three light modulators are arranged on the color synthesizing optical device, the orientation of the flexible substrate of one light modulator may be different from that of the other two light modulators, for examp...
