Description
Technical field
The present invention is about a kind of film circuit board, especially about a kind of film circuit board and this illuminated keyboard that is applied to illuminated keyboard.
Background technology
In recent years, because the information industry development is rapid, many users may use portable massaging device, such as notebook computer, mobile phone or personal digital assistant etc. under varying environment.At the weak environment of light, the user may not see numeral and the literal that indicates on Chu's keyboard, thereby causes operating difficulties, severe patient even may allow visual impairment because of inadequate identification button sign.Therefore, the release of illuminated keyboard can improve the user uses keyboard in the insufficient light place inconvenience.What is more, by different luminous configurations, can make and use the massaging device of illuminated keyboard to seem more attractive in appearance, and then increase its market.
See also Fig. 1, it is the structural profile schematic diagram of existing illuminated keyboard.Illuminated keyboard 1 comprises reflector 11, light guide plate 12, metal base plate 13, film circuit board 14, a plurality of button 15 and light-emitting component 16, wherein, film circuit board 14 comprises lower plywood 141, top plate 142 and the la m 143 between lower plywood 141 and top plate 142, and lower plywood 141, la m 143 and top plate 142 are all made by the transparent light guide material, and the transparent light guide material can be Merlon (PC) or polyethylene (PET) etc.
Moreover, please consult synchronously Fig. 2, it is the three-dimensional exploded view of the film circuit board of illuminated keyboard shown in Figure 1, top plate 142 has the first circuit pattern 1421 that is comprised of a plurality of elargol circuits 14211 and a plurality of upper contacts 14212, and lower plywood 141 has the second circuit pattern 1411 that is comprised of a plurality of elargol circuits 14111 and a plurality of lower contacts 14112, again, la m 143 has corresponding to the contact perforate 1431 of a plurality of upper contacts 14212 with a plurality of lower contacts 14122, wherein, lower contact 14112 common shape one thin film switches 144 that each upper contact 14212 is corresponding with it.In addition, each button 15 has keycap 151 and elastomer 152, and elastomer 152 is arranged between keycap 151 and the film circuit board 14.
When arbitrary button 15 touched and when moving down, keycap 151 can make elastomer 152 support its corresponding upper contact 14212 by extruding elastomer 152, and then make its corresponding upper contact 14212 contact corresponding lower contact 14112 via corresponding contact perforate 1431, make by this corresponding thin film switch 144 reach and electrically conduct, so that illuminated keyboard 1 produces a corresponding push button signalling.In addition, if the user no longer presses keycap 151, then keycap 151 can make progress springing to set back in response to the elastic force of elastomer 152.
Moreover, light-emitting component 16 is arranged at the side of light guide plate 12, inject light guide plate 12 in order to light to be provided, and light guide plate 12 is arranged on the reflector 11, and have a plurality of perforation 131 on the metal base plate 13, and the position that 131 pairs of these a plurality of perforation should a plurality of buttons 15 and being set up.Wherein, when light is injected light guide plate 12, light is flooded to whole light guide plate 12, and the up scattering of light of part in the light guide plate 12, the light of another part is down scattering then, up the light of scattering can be projected to film circuit board 14 and a plurality of button 15 by a plurality of perforation 131, and down the light of scattering can make upwards reflection of light via the auxiliary of reflector 11 again, is utilized so that the light that light-emitting component 16 provides can improve.As mentioned above, can make a plurality of buttons 15 produce luminous effect.Only, the existing film circuit board 14 that is applied to illuminated keyboard 1 has shortcoming as described below.
See also Fig. 3, it is the light path schematic diagram of the lower plywood of film circuit board shown in Figure 2.Because the first circuit pattern 1411 is arranged at the upper surface of lower plywood 141, and the first circuit pattern 1411 is comprised of a plurality of elargol circuit 14111, those elargol circuits 14111 have the character with light-ray condensing and scattering, therefore the light L1 that provides in light-emitting component 16 is via a plurality of perforation 131 of metal base plate 13 after entering lower plywood 141, the elargol circuit 14111 of the first circuit pattern 1411 can present shinny state, middle light L2 as shown, yet the setting of most of elargol circuit 14111 is not to be position corresponding to a plurality of buttons 15, therefore former should being used in makes a plurality of button 15 luminous light quantities be consumed because of the characteristic of elargol circuit 14111, that is to say, originally major part should be obtained by button 15 in the light quantity of light L1, but because the characteristic of elargol circuit 14111 is consumed the light quantity of light L2, therefore illuminated keyboard 1 only the light quantity of surplus light L3 can utilize, and then cause a plurality of buttons 15 on the illuminated keyboard 1 that the situation of deficiency in light quantity is arranged.
Therefore, have now and be applied to the film circuit board 14 of illuminated keyboard 1 because of the not good space with improvement of efficiency of light.
