Abstract
The utility model relates to a digital display gage unit with a backlight form, which is applies in a digital display gage of the a digital display caliper or the like, comprising a shell 2, a circuit board 8, a digital screen 4, a locating device 6 and a backlight plate 5, wherein the shell 2 and the locating device 6 have a locating effect on the backlight plate 5, the circuit board 8 and the backlight plate 5 are electrically connected and control the work of the backlight plate 5 by a functional button 3 on the shell of the digital display unit. The utility model increases a backlight function for the digital display gage unit, which not only solves the problem that the digital display unit is not easy to read in dark light, but also is characterized of a simple structure and a convenient manufacturing.
Description
Technical field
The utility model relates to the Electronic-digital Readout Measuring Tool assembly, is applied to products such as digimatic calipers, electronic digital display micrometer, digimatic height gage, electronic digital display indicating gauge.
Background technology
Current Electronic-digital Readout Measuring Tool both domestic and external is very universal, compares market share with mechanical measurer and improves year by year.Present most popular digimatic calipers adopts capacitive displacement transducer, and the relative position of capacitor plate is relevant on the output of sensor and main scale and the secondary chi, through the processing of electronic circuit, and the relative position data of demonstration on display screen.Electronic-digital Readout Measuring Tool has also been done a lot of work from user's ease for use, the domestic and international producer in comfortableness aspect, and wherein the visual observation of digital display appliance display part is an emphasis all the time, and operator's eyesight and environment for use are the principal elements of the correct reading of influence.Before this, the main work of manufacturer is to enlarge the area of liquid crystal display and the size of display digit, though improved operator's observing effect to a certain extent, the influence that still is subjected to environment is bigger.The demonstration of original Electronic-digital Readout Measuring Tool assembly adopts reflective LCD to show, the light that user's eyes receive is by LCD the reflection of ambient light to be produced, if work under the very dark indoor or field environment of light, then the user at all can't reading.
Summary of the invention
The purpose of this utility model be for provide a kind of can be under the very dark environment of light the Electronic-digital Readout Measuring Tool assembly of operate as normal, have simple in structure, easily manufactured characteristics simultaneously again, to adapt to the hand-held or portable requirement of Electronic-digital Readout Measuring Tool.
Of the present utility model can the realization by following measure:
Electronic digital display module for measuring tool with form backlight, this device comprises shell, circuit board, liquid crystal display, locating device and back light member, and liquid crystal display, back light member and locating device are between shell and circuit board, and circuit board is connected by screw with shell.Wherein:
Its back light member of described electronic digital display module for measuring tool is placed between liquid crystal display and the wiring board; Back light member is by locating device and liquid crystal display and shell location and fixing; Back light member and wiring board keep being electrically connected, and can be by the work of the control of the function key on electronic digital display module for measuring tool shell backlight.
The liquid crystal display of described electronic digital display module for measuring tool adopts transmission-type or semi-transparent semi.
The backlight of described electronic digital display module for measuring tool is the back light member by light emitting diode (LED) and light guide plate combination.
The backlight of described electronic digital display module for measuring tool also can adopt the back light member of electroluminescence (EL).
The back light member of described electronic digital display module for measuring tool with being connected of wiring board in adopted the connected mode of plain conductor, metal pins or flexible flexible cord.
This patent has increased backlight in original electronic digital display module for measuring tool, with original passive luminous passive luminous mode that combines with active illuminating of changing into, solved electronic digital display module for measuring tool is difficult for reading under dark environment problem.Because whether lighting of backlight is the circuit control that is subjected on button and the wiring board, therefore, can save the unnecessary electricity loss.Structurally only increased backlight and locating device, made the structure of original electronic digital display module for measuring tool not have to produce bigger variation, be convenient to electronic digital display module for measuring tool and install and make.
