Abstract
The utility model relates to a touch-control LCD (liquid crystal display) screen which comprises a first substrate, a second substrate arranged oppositely to the first substrate, and an LCD layer sandwiched between the first substrate and the second substrate. Conductive substances are respectively arranged at one side of the two substrates far away from the LCD layer. Both the internal structure and the manufacturing process of the touch-control LCD screen are simple; various performances and the appearance size of the LCD screen are not affected, such as the display effect, quality, thickness and the like; therefore, the cost is reduced to some degree, and the touch-control LCD screen is suitable for popularization and application.
Description
Technical field
The utility model relates to a kind of LCDs, refers in particular to a kind of LCDs of supporting touch-control.
Background technology
Along with the quick growth of current various consumption electronic products, PDA(Personal Digital Assistant), portable type electronic products such as mobile phone and PDA mobile phone have been extensive use of all has the interface tool that touch panel is linked up as data.Since the user can be directly by hand or other object contact touch control liquid crystal display device with input information, thereby reduce even eliminated the dependence of user miscellaneous equipment, as keyboard, mouse, telepilots etc. must make things convenient for user's operation like this, have also saved the space to a certain extent.
Common touch screen generally includes resistance-type at present, condenser type, acoustic wave type, polytypes such as infra red type, it is generally rectangular-shaped transparent panel, the mode that employing is piled up is arranged on a side of liquid crystal indicator display surface, and is connected to liquid crystal indicator and control corresponding device by flexible circuit board, thereby is implemented in the function of touch-control on the LCD.
But in the touch control liquid crystal display device of above-mentioned stacked structure, touch-screen and LCD need to make respectively, and then bond together, its cost of manufacture is higher, touch-screen is bonded in the display surface of LCDs usually by a bonding coat, this mode that connects touch screen and liquid crystal by bonding coat certainly will make the thickness of its whole display and weight increase.Simultaneously, because described touch screen and bonding coat have optical effects such as absorption, refraction and reflection to light, the light transmittance of liquid crystal indicator is reduced, and be easy to generate optical interference, cause display image distortion or variable color, reduce the display effect of touch liquid crystal display screen.
Therefore need solve above problem for users provide a kind of more effectively touch control type LCD display screen.
Summary of the invention
The actual technical matters to be solved of the utility model is how a kind of touch control type LCD display screen that can realize touching operation on liquid crystal display is provided.
In order to realize above-mentioned purpose of the present utility model, the utility model provides a kind of touch liquid crystal display, it includes first substrate, one second substrate that is oppositely arranged with this first substrate, and being clipped in liquid crystal layer between this first substrate and second substrate, described two substrates is respectively equipped with conductive materials away from a side of this liquid crystal layer.
Touch liquid crystal display screen described in the utility model, not only inner structure is simple for it, and production process is also uncomplicated, this device does not promptly influence the various performances and the apparent size of LCDs itself, as display effect, weight, thickness etc., do not need very accurate manufacturing accuracy just can be implemented in the purpose of directly touching on the LCDs yet, reduced cost to a certain extent, so be suitable for applying.
Description of drawings
Fig. 1 is the cut-away view of traditional LCDs;
Fig. 2 is the cut-away view of the utility model touch control type LCD display screen.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
See also shown in Figure 1, the inner structure synoptic diagram of at present general LCDs 1, its mainly comprise first substrate 11, second substrate 12 relative with this first substrate 11 and be clipped in this first substrate 11 and this second substrate 12 between liquid crystal layer 10.Between described first substrate 11 and liquid crystal layer 10, also be provided with a colored filter 13, this colored filter 13 is used to guarantee that LCDs 1 can demonstrate colour picture, and between second substrate 12 and liquid crystal layer 10, be provided with a thin film transistor (TFT) 13, crosstalking when this thin film transistor (TFT) can overcome non-gating effectively, make the static characteristics and the number of scanning lines that show liquid crystal display irrelevant, therefore improved picture quality greatly.Simultaneously, above described first substrate 11 and below described second substrate 12, promptly also be provided with a polaroid 15 respectively in the both sides away from liquid crystal layer 10, described polaroid 15 has polarity and dielectricity concurrently and has certain mechanical strength, thereby can realize the polarisation effect; This polaroid 15 is owing to just be arranged on the upside of upper substrate 11 and the downside of infrabasal plate 12, thus be equivalent to layer protective layer, so played the effect of protecting inner other structure of whole liquid crystal display to avoid the external object scratch.
Please refer to shown in Figure 2, cut-away view for this novel touch control type LCD display screen, it is loaded with a conductive materials of being made by the homogeneous transparent conductive material on traditional LCDs 1, as conductive layer 26, common have an indium tin oxide films ITO, since generally need be on glass substrate the two-layer ITO of cloth, be respectively X coordinate layer and the Y coordinate layer that is used for touch-control, so two-layer ITO directly can be loaded into the upside of first substrate 11 and the downside of second substrate 12, because liquid crystal layer 10 is clipped in the centre of described first substrate 11 and described second substrate 12, that is to say, described conductive layer 26 lays respectively at the side of two substrates away from this liquid crystal layer, so not only can be implemented in the function of direct touch-control on the LCDs, and saved the thickness of entire display screen, because whole device only need be when making LCD, after through necessary conventional process, on glass substrate, load two-layer ITO again and get final product, below our concrete again inner structure of discussing the LCDs 1 behind the loading ITO down.
Described touch control type LCD display screen 2, also comprise first substrate 21, second substrate 22 relative with this first substrate 21 and be clipped in this first substrate 21 and this second substrate 22 between liquid crystal layer 20.Between described first substrate 21 and liquid crystal layer 20, also be provided with a colored filter 23, and between second substrate 22 and liquid crystal layer 20, be provided with a thin film transistor (TFT) 24, also also be provided with a polaroid 25 respectively in both sides away from liquid crystal layer 20, be positioned at the upside of first substrate 21 and the downside of second substrate 22, the two-layer ITO of the described X of having coordinate layer and Y coordinate layer lays respectively between first substrate 21 and the polaroid 25 and between second substrate 22 and the polaroid 25.For better protection ITO, also need between ITO and polaroid 25, to add one deck separation layer 27 respectively, to avoid the influence of 25 couples of ITO 26 of polaroid.Like this, in the processing procedure of whole LCDs, owing to loaded ITO with touch controllable function, so can effectively realize touch controllable function, moreover, because ITO itself is just quite thin, and the separation layer that covers thereon is also very thin, so whole device influences the thickness and the weight of LCDs hardly.
Touch control type LCD display screen of the present invention, not only inner structure is simple for it, and only manyly when making to be implemented in the purpose of directly touching on the LCDs once the step operation, and do not influence the various performances and the apparent size of LCDs itself, as display effect, weight, thickness etc., also do not need very accurate manufacturing accuracy requirement, cost is also relatively low, so be suitable for applying.
