Description
The present invention relates to an optical joystick applicable to a user interface of an electronic device such as a portable terminal and a manufacturing method thereof.
In general, electronic devices such as mobile terminals and PDAs (Personal Digital Assistants) generally adopt a user interface using a keypad.
In more detail, a typical portable electronic device includes a keypad having a plurality of buttons for inputting numbers, letters, or symbols, and a user presses a button on the keypad to input desired data such as numbers or words. You can type in or select the menu.
In addition, the portable electronic device includes a display unit to display data input by the user through the keypad and / or related information.
In recent years, wireless Internet services such as WIBRO (Wireless Broadband) and wireless mobile communication services have been commercialized to support communication services and Internet services using electronic devices.Graphical User Interface (GUI) has been adopted for mobile electronic devices such as mobile phones and PDAs. Windows operating systems, such as Windows CE, are being adopted to support this.
In addition, with the development of communication technology, the portable electronic device provides various additional services to the user, and the GUI-based Windows operating system facilitates the provision of the additional service by the portable electronic device.
A user interface for more convenient use of a general electronic device is a pointing device such as a mouse, a touchpad, a joystick, etc. Recently, a pointer such as a cursor is detected by detecting an optical signal that changes according to the movement of a finger, which is a subject. Optical joysticks that move or receive information and / or commands desired by the user have been developed and applied to electronic devices.
1 is a schematic cross-sectional view showing the operation principle of a conventional optical joystick.
First, the conventional
Referring to the drawings, the
When the user comes into contact with the subject P on the surface of the housing, the conventional
Infrared rays introduced into the
The microcomputer generates a cursor on the display screen according to the received displacement value.
Therefore, the user can conveniently select the displayed icon or the like using the generated cursor.
However, the conventional optical joystick configured as described above has a problem that the work process is cumbersome and the assembly is inferior because the worker has to separately prepare the housing, the holder, the imaging member, the image sensor, and the like, and then manufacture the completed module.
That is, in the conventional optical joystick, the housing, the holder, the imaging member, and the image sensor are manufactured, respectively, and then the operator has to assemble one by one according to the assembling order using a separate tool.
In order to compensate for this problem, the entire assembly process should be automated. However, since the size of each component is too small, it is difficult to automate the entire assembly process, and only a part of the assembly process can be converted into an automated process.
Therefore, the assembly of the conventional optical joystick has not been greatly improved.
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide an optical joystick and a method of manufacturing the same, which can be expected to improve productability as well as to improve assembly performance by simplifying the assembly process.
The optical joystick and the method of manufacturing the same according to the embodiment of the present invention have the effect of improving the assembly performance through the simplification of the assembly process and of improving the productability with a slimmer standard.
In order to effectively achieve the above object, the present invention, the light source member and the image sensor mounted on the substrate is a lower package formed by molding through a transparent sealing material; An upper package corresponding to the light source member and the image sensor of the lower package, the upper package of which an illumination system and an imaging system configured to be in close contact with each other, are molded through an external light shielding material; Characterized in that it comprises a.
The lower package and the upper package may be accommodated in a housing having a subject contact surface, and the housing may include a transmission zone through which light of the light source member is transmitted and a non-transmission zone through which the light is not transmitted.
In addition, the illumination system is characterized in that the molding is configured vertically or inclined.
A blocking film may be provided between the light source member and the image sensor to block a light source emitted from the light source member. The blocking layer may be a black EMC, and may include a mask in which a tape, a light source member, and an image sensor are fitted at the same time, and are in close contact with a substrate.
At this time, any one of a boss or a gasket for adjusting the height of the upper package may be further provided between the lower package and the upper package.
In addition, the imaging system may be configured of a green index lens (GRIN LENS).
On the other hand, the imaging system may be further provided with a filter for blocking the inflow of light other than the infrared wavelength band, the filter may be a coating material formed on any one of the top, bottom, front surface of the imaging system.
In addition, the filter may be a tape formed on any one of an upper surface, a lower surface, and a front surface of the imaging system.
In addition, the external light shielding material may be made of black EMC.
The optical joystick of the present invention is also configured to closely contact one end of the illumination system and the imaging system, respectively, to correspond to the light source member and the image sensor mounted on the substrate, and the other ends of the illumination system and the imaging system that are not in close contact are configured to closely adhere to each other, and surround them. It is characterized in that the external light shielding material is filled to be molded.
The lower package and the upper package may be accommodated in a housing provided with a subject contact surface, and the housing may include a transmission zone through which light of the light source member is transmitted and a non-transmission zone.
The imaging system may be a green index lens, and the external light blocking material may be formed of black EMC.
The illumination system may be configured to be molded vertically or inclined.
On the other hand, the optical joystick of the present invention comprises the steps of mounting a light source member and an image sensor on the substrate; Manufacturing the lower package by molding the light source member and the image sensor with a transparent encapsulant and a blocking film; Manufacturing an upper package by arranging lower ends of an illumination system and an imaging system so as to correspond to the light source member and the image sensor, and forming upper ends of each side in close contact with each other and molding the external light blocking material; Combining a housing including a transmission zone and a non-transmission zone such that the upper package and the lower package are wrapped; It further includes.
In addition, mounting the light source member and the image sensor on the substrate; Closely contacting the illumination system and the imaging system to correspond to the light source member and the image sensor, and configuring the other ends of the illumination system and the imaging system that are not in close contact with each other; Filling and molding an external light shielding material after the light source member, the image sensor, the illumination system, and the imaging system are in close contact with each other; Combining a housing including a transmission zone and a non-transmission zone after the external light blocking material is molded; It further includes.
