Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application is a continuation of U.S. application Ser. No. 18/772,448 filed Jul. 15, 2024 which is a continuation of U.S. application Ser. No. 17/616,416 filed Dec. 3, 2021, which is a 371 of PCT/CA2020/050761 filed Jun. 3, 2020, which claims the benefit of 62/856,501 filed Jun. 3, 2019. The contents of each of these prior applications are incorporated herein by reference in their entirety. BACKGROUND AND FIELD OF THE INVENTION The present disclosure relates to a wearable head-mounted device employing one or more displays with an optical system placed on top of the display. Conventionally, head-mounted devices (HMDs) have one or two displays with digital projectors and microscopic mirrors embedded in the device to project images onto an eye of a user. Because of all this circuitry, often the HMDs are heavy and difficult to carry for longer periods of time. Further, these devices offer a limited field of view and a displeasing experience for the user. Moreover, the display may include cathode ray tubes (CRT), liquid-crystal displays (LCDs), liquid crystals on silicon (LCos), or organic light-emitting diodes (OLED). These conventional displays suffer with low brightness, high power consumption and shorter life span. Therefore, there is a need for an improved HMD that is simple in structure and can offer a better field of view, high brightness, and low power consumption. SUMMARY According to one embodiment, a wearable HMD may be provided. The wearable HMD may be integrated with a microLED display to offer simple structure, better resolution, contrast, luminance, and low power consumption compared with conventional devices. According to another embodiment, the head mounted device may comprising a frame having at least one arm, at least one display coupled at a proximity edge of the arm, an electronic system coupled at a proximity another edge of the arm, a data processing unit configured to send and receive data from the display, wherein the data processing unit coupled through the arm between the electronic system and the display; and an optical system configured to project an image from the display to a user's eye, wherein the optical system is mounted at the top of the display. In another embodiment, the optical system may be placed between the display and the user's eye. In one case, the optical system may comprise a concave lens. In one embodiment, the electronic system may comprise a computing device, a communication unit, a synching unit, and a power unit. In another embodiment, the display may comprise a micro light emitting diode microdisplay. In one case, the arm attached to the frame may be made of transparent materials. In another case, the arm may comprise conductive traces for communicating and providing power to the display. The arm may be flexible. In another embodiment, the HMD may comprise one or more sensors configured to the head mounted device to detect a motion of the eye to start projecting the image from the display. In one embodiment, the HMD may further comprise one or more sensors to measure the eye focus distance to adjust the optic focal point for the image to be in the focus point of the eye. In one embodiment, the arm and the display may be integrated to the frame. According to another embodiment, there may be one two or more displays mounted on the frame or mounted on the arm. The two or more displays cover a wider viewing angle for the user. According to one embodiment, a head mounted device may be provided. The head mounted device may comprising: a frame having at least one arm, at least one display mounted on the frame in front of a user's eye, an electronic system coupled at a proximity edge of the arm; and an optical system placed between the display and the user's eye to project an image from the display to the user's eye. According to one embodiment, a method of displaying an image on a head-mounted device may be provided. The method may comprising providing a frame having at least one arm, mounting at least one display on the frame in front of a user's eye, coupling an electronic system at a proximity edge of the arm; and placing an optical system between the display and the user's eye to project an image from the display to the user's eye. In one case, the two display system may provide images with different content seen at the same time. This feature can be used to show the 3D images, increase the resolution, or add color through showing different colors to each display. According to another embodiment, the displays may be mounted further away from the edge of the frame. In one case, the power and signal lines may go through a transparent lens or a coil inside the frame may provide power or data to the display. The foregoing and additional aspects and embodiments of the present disclosure will be apparent to those of ordinary skill in the art in view of the detailed description of various embodiments and/or aspects, wh
