The utility model content
The utility model provides a kind of LCD TV with touch key-press, has solved touch panel unit complex structure, maintenance not easy to assemble, the low inferior problem of the whole transmitance of light, has improved the result of use of the LCD TV of band touch key-press.
A kind of LCD TV described in the utility model with touch key-press, comprise LCD TV and the touch panel unit that is installed on LCD TV screen the place ahead, touch panel unit comprises shell, transparency carrier, circuit board assemblies and light transmission piece, described shell is the rectangle frame that the flat profile by four hollows combines, circuit board assemblies and light transmission piece are embedded in respectively in the interior corresponding dead slot of shell, etching has some tin indium oxide touch key-presss on the transparency carrier top layer, each button is drawn the touch key-press pin, described pin connects the capacitance type touch key chip, and capacitance type touch key chip identification touch key-press also feeds back to driving governor with discre value.
The LCD TV of band touch key-press described in the utility model, the tin indium oxide touch key-press surface coverage on its transparency carrier has the polaroid protective layer.
The LCD TV of band touch key-press described in the utility model offers one for connecting the winding displacement passage that each touch panel unit winding displacement passes through on its transparency carrier.
The LCD TV of band touch key-press described in the utility model, the outer side edgefold of the face-piece of its shell and drain pan is interlocked, and the shape of cross section after fastening all is the L type.
The LCD TV of band touch key-press described in the utility model, its shell comprises face-piece and drain pan, offer a printing opacity film trap on the inner side edge of face-piece and drain pan, also offer the substrate draw-in groove of an arrangement transparency carrier on the interior side section of its drain pan, solve the defective tightness of getting in touch around light transmission piece and the LCD TV screen surface with this, be easy to generate the deficiency that the slit has directly influenced its waterproof and dustproof.
The LCD TV of band touch key-press described in the utility model, the drain pan inner surface of its shell offers the draw-in groove of being convenient to place circuit board assemblies.
Owing to adopted above-mentioned technical scheme, when assembling the LCD TV of band touch key-press described in the utility model, earlier be separately fixed at the circuit board assemblies in the touch panel unit in the draw-in groove of four foundation shells by screw, then with four face-pieces respectively correspondence be interlocked on four foundation shells, and be fixed by some screws and form four flat section bars, light transmission piece places the printing opacity draw-in groove between face-piece and the drain pan, four limit correspondences of transparency carrier are inserted in four substrate draw-in grooves of side section in the drain pan, two ends with face-piece are screwed rectangular touch screen assembly of formation by four contiguous blocks respectively then, connect in the just corresponding respectively winding displacement passage that is placed on the contiguous block face of winding displacement of each piece touch panel unit, effectively avoided so just having finished the assembling of whole touch screen assembly because of winding displacement twines the problem that causes loose contact.Debug good touch panel unit before connector is locked in the LCD TV screen with screw threads, and be screwed in front shell of television, the more forward and backward shell of television set is loaded onto the assembling of the LCD TV of promptly having finished whole band touch key-press through connector.
A kind of LCD TV described in the utility model with touch key-press, not only be convenient to installation, debugging to touch panel unit, also help at touch-screen and detect maintenance and maintenance when unusual, good airproof performance between light transmission piece and toughened glass and the shell does not have the slit, reaches requirement explosion-proof, waterproof and dustproof.
Description of drawings
