Embodiment
Bad and the undesirable technical barrier of high temperature and humidity test of the watermark that the scheme of arranging in pairs or groups in view of current low cost occurs, the utility model patent passes through validation trial, sum up a high performance-price ratio arranging scheme, successfully solve this technical barrier, once very large contribution will be made for this industry by popularization.The utility model provides a kind of anti-watermark to produce the full laminating LCM of low cost arranging scheme, for making the purpose of this utility model, technical scheme and effect definitely, below in conjunction with the drawings and specific embodiments, the utility model patent is further described, described concrete enforcement only for explaining the utility model, and is not used in restriction the utility model.
Fig. 1 is full laminating LCM cut-open view, wherein representated by label, parts are as follows: cover-plate glass (cover plate Glass) 1, OCA(opticalclearadhesive) optical cement 2, sensor (Sensor) the 3, the 2nd OCA optical cement 4, upper polaroid 5, LCD colored filter (ColorFilter, be called for short CF) 6, LCD thin film transistor (TFT) (ThinFilmTransistor, TFT) 7, lower polaroid 8, black and white glue 9, upper bright enhancement film 10, lower bright enhancement film 11, diffusion barrier 12, light guide plate 13, reflector plate 14, steel framework 15, glue frame 16.
Shown in the full laminating LCM cut-open view referring to Fig. 1, full laminating LCM is made up of LCD display module, capacitive touch screen TP, the large module of backlight three, wherein, LCD display module and capacitive touch screen TP are bonded together by OCA optical cement, LCD display module is passed through together with black and white glue with backlight, and three defines an entirety.
Wherein, LCD display module is made up of upper polaroid 5, LCD colored filter 6, LCD thin film transistor (TFT) 7, lower polaroid 8, wherein going up polaroid 5 is attached on LCD colored filter 6, and LCD colored filter 6 and LCD thin film transistor (TFT) 7 are lower-glass in liquid crystal display.
Capacitive touch screen TP is made up of cover-plate glass 1, an OCA optical cement 2, sensor 3, the 2nd OCA optical cement 4, wherein an OCA optical cement 2 is for fitting together cover-plate glass 1 and sensor 3, and the 2nd OCA optical cement 4 is for fitting together the upper polaroid 5 in sensor 3 and LCD display module.
Backlight is made up of black and white glue 9, upper bright enhancement film 10, lower bright enhancement film 11, diffusion barrier 12, light guide plate 13, reflector plate 14, steel framework 15, glue frame 16.From top to bottom successively order be that black and white glue, upper bright enhancement film, lower bright enhancement film, diffusion barrier, light guide plate, FPCA(are with light emitting LED lamp pearl), reflector plate, steel framework bottom surface, glue frame is integrated through injection molding structure with steel framework, is attached to the position of the upper surface 0.10mm of the upper polaroid height plastic emitting frame on LCD.
Fit together by the 2nd OCA optical cement 4 in the middle of LCD display module and capacitive touch screen TP, the lower polaroid of LCD display module passes through together with black and white glue with backlight, and three defines an entirety.
In general, watermark bad generation immediate cause is that the upper bright enhancement film 10 of backlight and lower polaroid 8 absorption of LCD display stick together, and forms a band steam shape trace print.In order to product reaches high brightness, band brightened type polaroid selected by lower polaroid 8, and simultaneously in order to reduce the absorption affinity to bright enhancement film on backlight 10, some mist degrees are with by lower polaroid 8.
In order to film strength of adding lustre on strengthening, make it not easily be got on by lower polaroid 8 absorption when high-temperature high pressure, upper bright enhancement film 10 selects the bright enhancement film material of 0.095mm thickness, and relatively conventional wants thick 0.025mm, effectively enhances its intensity.
In order to reduce the integral thickness of product, the glue frame 16 of backlight adopts integrated through injection molding structure with steel framework 15, eliminates the space of assembly clearance and double faced adhesive tape, and what product can be done is thinner, and structural strength is good simultaneously.
This structural design is because of thinner in order to what make product do, steel framework adopts thickness to be 0.15mm, see Fig. 2, in order to reduce, its degree of deformation is excessive causes generation watermark bad, steel framework adopt 6 places to distribute symmetrically cross, eliminate the internal stress of the generation of steel framework in punching course, thus reduce degree of deformation.
The advantage to sum up had can accomplish to meet product brightness and display effect, stop again the generation of watermark, the common polaroid of polaroid is relatively descended to add this arranging scheme of bright enhancement film 3MBEFRP2 on backlight, cost declines a lot, larger economic benefit will be created to enterprise, to whole industry, there is very large using value.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
