Abstract

The utility model relates to a rotatory polarization touch-sensitive liquid-crystal film set, which mainly comprises an internal 1/4 wavelength phase difference film arranged on a liquid-crystal display panel in order,,a touch-sensitive panel, an external 1/4 wavelength phase difference film and an external polarization film; wherein the polarization film and the 1/4 wavelength phase difference films provides good penetrability for the beam of the internal light source, to make the liquid-crystal film set have high brightness, besides, the external polarization film and the 1/4 wavelength phase difference films can hinder the reflection of the external light, thereby reducing the drawbacks of that: the external environment is reflected on the liquid-crystal film set, and that disturbs the clarity of the output picture.

Description

Rotatory polarization type touch liquid crystal module

[technical field]

The utility model relates to a kind of liquid crystal module, refers to a kind of rotatory polarization type touch liquid crystal module especially.

[background technology]

The opto-electronics development rapidly, make the technology of display enter to slim electricity slurry and LCD epoch by cathode-ray tube (CRT) epoch of large volume, do not account for the advantage of volume, light weight because latter's display has thin thickness, be subjected to the narrow and small gradually modern's of home environment favor at present gradually.

With LCD, it not only can use as TV, also can arrange in pairs or groups computer and be used in desktop computer or notebook computer, with notebook computer, since its often by the user be carried into the open air or not particular place use, so it is good to be seated in the display device structure intensity of fixed-site on the structural strength.

Existing LCD is to cover an one deck cure process layer or an anti-reflective film are set on a liquid crystal panel; the cure process layer is to protect liquid crystal panel not to be subjected to scratch or external shock; anti-reflective film can reduce the reflex of light on display in addition, so that a picture clearly to be provided.

Yet; the briliancy of existing LCD is not high; when LCD during in the open air use; strong excessively through regular meeting because of extraneous light; the image frame that makes display send can't be brought into play preferable visibility under extraneous high light; cause the user can't clearly watch this image frame; in addition; on the panel of display; still can mirror the image (as mirroring user's dazzling sunlight behind) of high light because of emergency light reflex, again LCD in use between one long afterwards, it is obscure that briliancy can become gradually; even allow the user at the indoor image frame that also is difficult to watch on the display, so all there is the problem that the briliancy deficiency is arranged in general display panels.

[utility model content]

There are shortcomings such as briliancy deficiency and emergency light reflex in view of the available liquid crystal display, fundamental purpose of the present utility model provides a kind of rotatory polarization type touch liquid crystal module, this liquid crystal module has high briliancy, and can avoid the shortcoming of showing extraneous image because of emergency light reflex in liquid crystal module.

For reaching above-mentioned purpose, the utility model provides a kind of rotatory polarization type touch liquid crystal module, it is characterized in that: foldedly in regular turn on a display panels be provided with in one outside 1/4 wavelength phase retardation film, the contact panel, a light polarizing film outside the 1/4 wavelength phase retardation film.

By above-mentioned technological means, phase differential film outside light polarizing film reaches outside external environment light passes, the physical characteristics of light is changed, make when light runs into dieletric reflection, can't pass second light polarizing film once more, the problem that can avoid the liquid crystal display module under high light, to mirror extraneous image by this and cause self image to be interfered, in addition, display panels internal light source emitted light, during in regular turn through interior phase retardation film and outer phase differential film, the physical characteristics of light is changed, and then can pass completely through outer light polarizing film, can improve the penetrance of source light by this, improve so that show the image frame briliancy of module.

Fig. 2 is a partial exploded view of the present utility model.

Fig. 3 is a stereo appearance figure of the present utility model.

[embodiment]

Please refer to Fig. 1,2,3, the utility model rotatory polarization type touch liquid crystal module is mainly foldedly in regular turn on a display panels (10) to be provided with outside phase retardation film in (20), the contact panel (31), a light polarizing film (33) outside the phase differential film (32).

Should interior phase retardation film (20) be 1/4 wavelength (λ), the polarization linear light through should in during phase retardation film (20), become the circular polarized light of a single direction, for example, the linear light of horizontal direction changes circular clockwise light into, or the circular light of counterclockwise changes the linear light of vertical direction into.

This contact panel (31) provides touch instruction input function, also is a fender.

Should outer phase differential film (32) also be 1/4 wavelength (λ), its function be the function as the interior phase retardation film of 1/4 wavelength (λ) (20) in aforementioned.

The utility model below will be described in detail in detail how effectively reduce the reflectivity that external environment light is incident in the liquid crystal display module, and the briliancy that how to improve the liquid crystal display module.

When extraneous light enters the demonstration module, be earlier by being somebody's turn to do outer light polarizing film (33), suppose that this outer light polarizing film (33) is a horizontal direction, then light changes the linear light of a horizontal direction into, then through outer phase differential film (32), and change a circular polarization light clockwise into, when light runs into a medium and reflex time, reflection ray passes through outer phase differential film (32) once more, and change the linear light of a vertical direction into, the light of this vertical direction can't pass the outer light polarizing film (33) of horizontal direction at this moment, by this, make extraneous incident ray finally can't reflect the liquid crystal display module, so the liquid crystal display module will can not mirror the picture image that extraneous image disturbs liquid crystal display module self.

When display panel (10) internal light source produces light, light is earlier by behind interior light polarizing film and the interior phase retardation film (20), change the circular polarized light of a single direction into, as the clockwise circular polarized light, after then light enters outer phase differential film (32), change the linearly polarized photon of a single direction into, as the horizontal direction linearly polarized photon, last light can pass completely through outer light polarizing film (33) and outwards penetrate, by inside/outside light polarizing film (33) and inside/outside phase retardation film (20) (32), can make the light of internal light source effectively pass the liquid crystal display module and reduce light losing, can make the liquid crystal display module have high briliancy by this.

Please refer to Fig. 2, below will introduce the manufacture of liquid crystal display module.

Aforementioned contact panel (31), outer phase differential film (32) and outer light polarizing film (33) combine with the attaching machine and become a composite bed (30).Afterwards display panel (10) is combined with the attaching machine with interior phase retardation film (20), again with composite bed (30) with double faced adhesive tape adhesion be integrated (shown in Figure 3) as the.

By above-mentioned technological means, inside/outside light polarizing film (33) and inside/outside phase retardation film (20), (32) provide the good penetrability of light of internal light source so that the liquid crystal display module has high briliancy, in addition, outer light polarizing film (33) and outer phase differential film (32) are that the reflection of blocking extraneous light can be arranged, and reduce external environment by this and reflect on the liquid crystal display module and disturb the shortcoming of exporting picture.
