1261556~— ----—______ V. INSTRUCTION DESCRIPTION (1) (I) Technical Field of the Invention The present invention relates to a display mirror and a method of manufacturing the same, and more particularly to a function of generating information and images. Display mirror and its manufacturing method. (1) [Prior Art] Mirrors have the function of reflecting images and are widely used in daily life. For example, it can be used on a car or a locomotive, as a rear mirror and a side mirror; or it can be used in a parking lot or a curved mountain road where there is a blind spot of sight, used as a turning mirror, and the like. In recent years, in order to cope with the development of electronic systems and to expand the use of mirrors, the industry has attempted to combine mirrors with display devices so that the mirrors have the dual functions of displaying images and reflecting images. Taking the rear mirror as an example, at present, the manufacturer directly adds a display to the back of the lens, and the method is to cut a range in the center of the lens, and set the display I in it. However, in this technique, the area in which the display device is disposed does not have the function of reflecting the image, and the area that can be truly reflected is thus reduced, so that the reflection angle of the entire rear mirror cannot be maintained intact, resulting in safety concerns on the road. In addition, some companies have added a Light Emitting Diode (LED) behind the lens of the rear mirror. However, due to the poor resolution of the overall image, it cannot be applied to image display with high information density; and since the illuminating crystal of the LED is modularized, the size becomes larger, and the display mirror loses its original plane thinness. Layered features. Furthermore, there is also a manufacturer who adds a liquid crystal display behind the lens of the rear mirror.

Page 6 1261556 —--- _ five, invention description (2) " ' """""" (Liquid Crystal Display, LCD). Although the liquid crystal display can have better image quality, since the liquid crystal molecules perfused by the liquid crystal display itself do not emit light, it is necessary to add a backlight to the back side to illuminate the image, so the luminous efficiency, contrast, and viewing angle are not ideal. At the same time, due to the complex structure of the liquid crystal display, and the need to match materials such as backlights, color filters and polarizing plates, the cost is relatively high, which is not conducive to market applications. Due to the expansion of the application field and the increase in the transmission of information content, the currently used mirrors with display functions are unable to meet the image resolution and information content requirements. In view of this, there is a need for a new display mirror to solve the shortcomings of the above conventional techniques. The inventor, in view of this, is in the spirit of active invention, and is thinking of a "display mirror and its manufacturing method" that can solve this problem. After several research experiments, the invention of the world has been completed. (3) [Explanation] In view of the above problems, an object of the present invention is to provide a display mirror having a display function and a method of manufacturing the same. The invention features a mirror panel having a light transmissive reflective layer in combination with a display device. In order to achieve the above object, a method of manufacturing a display mirror according to the present invention includes the steps of: first providing a mirror panel having a light transmissive reflective layer, then providing a display device, and then having a light transmissive reflective layer; The mirror panel is assembled with the display device group.
