Method for optimizing projection image, projection display module and electronic equipment

Abstract

The invention provides an optimization method of a projected image. The method comprises the following steps of providing a first projected image formed by first direction projection light; when the first projected image possesses a shadow, acquiring a shadow area of the first projected image; according to the acquired shadow area, calculating a brightness loss of the first projected image in the shadow area; providing a second projected image formed by second direction projection light, wherein a first direction and a second direction are opposite to each other, and the second projected image and the first projected image are superposed in a counterpoint mode; and promoting brightness of the second projected image in the shadow area so as to compensate the brightness loss of the first projected image in the shadow area. The invention also provides a projection display module and electronic equipment. By using the method, the module and the equipment of the invention, a problem that the brightness is non-uniform because an object shields the projected image is solved and display quality of the projected image is greatly increased.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a projection image optimization method, projection display module and electronic equipment. Background technique [0002] At present, existing mobile electronic devices (such as mobile phones, tablet computers, and smart watches) are generally composed of touch screens, batteries, motherboards, and casings; among them, touch screens are one of the most important devices, and they are used to realize Necessary devices for human-computer interaction. [0003] With the demand of the market, mobile electronic devices are developing toward touch screens with higher image quality and high brightness. However, due to the relatively large volume of the touch screen itself, it not only limits the display area, but is also relatively easy to break. Therefore, the high cost of the display screen, inflexible display, and mostly radiation are its unavoidable shortcomings. [000...

Problems solved by technology

[0005] However, in electronic equipment with a projection display module, although the projected image is optimized in the debugging step, some dark spots will appear on the display screen during use because fingers or other obstacles block part of the light from the projection device. area, resulting in a picture with uneven brightness displayed on the image, which affects the normal viewing and quality of the image
