As described above, the touch screen according to the related art is configured such that the shape of the keypad is formed on the light transmitting sheet, and the light is illuminated from the back surface of the keypad. Therefore, in such a configuration, since the illumination is given priority in order to use the touch screen, the power consumption is large. Further, since the light is made on the rear surface of the light transmitting sheet, the thickness for the electronic device for lighting must be secured, and therefore the thickness of the touch screen is inevitably large.

In order to solve the above-described problems, the present invention intends to implement a touch screen in a totally new way. We also want to minimize the thickness of the touch screen by improving the illumination method for the touch screen.

According to an aspect of the present invention, there is provided a touch screen of a transmissive display type, comprising: a transparent substrate of transparent material; and an electrode pattern of a transparent conductive material, wherein a touch for user authentication is sensed at a predetermined position on the transparent substrate A touch panel including an electrode pattern; A liquid crystal panel including a first transparent layer and a second transparent layer of transparent material disposed at predetermined intervals and a liquid crystal layer interposed between the first transparent layer and the second transparent layer and in which light transmission and light shielding are switched by a control signal, ; A background pad on which any form is visually printed; And controlling the light projection and the light shielding of the liquid crystal panel by applying the control signal in a state in which the touch panel, the liquid crystal panel, and the background pad are configured, and when the liquid crystal panel is controlled in the light projection state, And a control module for generating and outputting the touch information indicating the specific type when a touch for the user authentication is sensed at a position corresponding to the specific type.

The liquid crystal panel may further include illumination means for emitting illumination light to at least one side surface of the first transparent layer and the second transparent layer of the liquid crystal panel into the corresponding layer, And controls the illumination means to emit the illumination light when the panel is controlled to be in a light projecting state.

The control module may further include a brightness sensor for measuring a brightness of the surroundings and outputting a brightness signal, wherein the control module controls the brightness of the illumination light corresponding to the brightness signal when the liquid crystal panel is switched to the light- have.

Further, the specific form printed on the background substrate may be a keypad having two or more numerals, and the control module may detect that a position corresponding to at least two numbers is simultaneously touched at the same time on the touch panel , The liquid crystal panel is switched to the light projection state.

In addition, by forming the electrode pattern on the first transparent layer or the second transparent layer of the liquid crystal panel, the liquid crystal panel in which the electrode pattern is formed can simultaneously perform the function of the touch panel.

The shape of the keypad to be printed on the background pad may be printed on the surface of the first transparent layer of the liquid crystal panel or on the surface of the second transparent layer.

According to the present invention, there is provided a deadbolt control system comprising a deadbolt driver for operating a dead bolt to switch a door to a locked state or a unlocked state, and a deadbolt driver for storing the authentication password, A mortise module including an authentication control unit for controlling the operation of the deadbolt driver; A touch panel including a transparent transparent substrate and an electrode pattern for sensing a touch for user authentication at a predetermined position on the transparent substrate as an electrode pattern of a transparent conductive material; A liquid crystal panel including a first transparent layer and a second transparent layer of transparent material disposed at predetermined intervals and a liquid crystal layer interposed between the first transparent layer and the second transparent layer and in which light transmission and light shielding are switched by a control signal, ; A background pad on which at least two numbers are visually printed; And controlling the light projection and the light shielding of the liquid crystal panel by applying the control signal according to a user's request in a state in which the touch panel, the liquid crystal panel, and the background pad are configured.

According to the transmissive display type touch screen of the present invention having the above-described configuration, a keypad is implemented in a new way, and thus a sense of beauty can be provided to the user.

In addition, since the keypad can be seen without performing illumination separately for each key position of the keypad, a touch screen that operates with minimum power can be implemented.

Also, the power consumption is small even when the keypad is illuminated.

In addition, since illumination can be performed on the side surface of the liquid crystal panel, the thickness of the touch screen can be minimized.

2 is a cross-sectional view showing a configuration of a panel module of a transmissive display type touch screen.
FIG. 3 is a cross-sectional view of each module constituting the panel module shown in FIG. 2. FIG.
4 is a view showing another method of configuring the panel module.
FIG. 5 is a view schematically showing a configuration of a door lock device having a transmissive display type touch screen according to the present invention.

FIG. 1 is a view schematically showing a configuration of a transmissive display type touch screen according to the present invention. Referring to the drawings, a transmissive display type touch screen according to the present invention includes a panel module and a control module. Further, the panel module includes a touch panel, a liquid crystal panel, and a background pad. In addition, the control module can perform a corresponding function by the touch sensing function unit, the liquid crystal control function unit, and the illumination control function unit. Meanwhile, the touch screen according to the present invention may further have a lighting means and a brightness sensor.

The panel module provides a keypad with at least two numbers or symbols, etc., and outputs an electrical signal corresponding to the touched position of the user's finger. The control module analyzes the electric signal output from the panel module and determines which number or symbol the user intends to input by touching a certain key.

First, in the panel module, the touch panel is composed of a transparent substrate made of a transparent material and an electrode pattern of a transparent conductive material formed on the transparent substrate in a printing or coating manner. Such a structure of the touch panel can be used in a general touch device. In addition, any sensing method such as a capacitive sensing method, a pressure sensing method, and the like can be applied to the touch panel, and the electrode pattern formed thereby can also be changed.

The liquid crystal panel is inserted in the space between the first transparent layer and the second transparent layer of the transparent material overlapped with the predetermined interval and the overlapping first transparent layer and the second transparent layer and is optically And a liquid crystal layer in which properties are changed to switch between light transmission and light shielding.

Such a liquid crystal layer can be switched between the alignment state and the non-alignment state depending on whether or not the control signal is applied, whereby the light projection and the light shielding can be controlled. The structure and operation of such a liquid crystal layer can be understood with reference to a liquid crystal panel known in, for example, Korean Laid-Open Patent Application No. 2013-10066 (name: contrast adjustment window).

The background pads are visually printed in an arbitrary shape. At this time, the printed form may be in the form of a keypad including, for example, at least two numbers or symbols. Generally, the keypad has 10 numbers and 2 symbols displayed in a 3x4 array (see FIG. 2). Or background pads, numbers or symbols may be displayed in a different manner, e.g., dialed or randomly arranged.

Next, in the control module, the touch sensing function unit drives the touch panel to detect the position where the touch of the finger occurs on the touch panel. The sensed touch position is associated with the position of each designated number or symbol printed on the background pad to determine which number or symbol the user wants to touch and outputs touch information indicating the corresponding number or symbol. The outputted touch information may be provided to another electronic device or may be provided to a later-described Moris module.

The liquid crystal control function unit controls the light projection and the light shielding of the liquid crystal panel by selectively applying an electrical control signal to the liquid crystal panel.

The lighting control function controls lighting of the panel module. In the touch screen according to the present invention, the panel module may further comprise lighting means, and the lighting control function controls the operation of the lighting means. Further, the touch screen according to the present invention may further include a brightness sensor. The brightness sensor senses the brightness of the surroundings, and on / off of the lighting means or the intensity of illumination may be controlled according to the detection result.

The illuminating means illuminates the background pads such that when the liquid crystal panel in the panel module is operated in the light emitting state, the printed form of the background pads can be seen more clearly by the user. For this purpose, the illumination means may comprise one or a plurality of light emitting elements (for example, light emitting diodes; see FIG. 2), the plurality of light emitting elements being, for example, As shown in FIG. By arranging the luminous means as described above, the emitted illumination light can be emitted substantially uniformly from all the surfaces while being reflected inside the surface of each luminous layer within the first or second luminous layer constituting the liquid crystal panel, It is possible to uniformly illuminate the surface of the rear keypad substantially entirely.

Meanwhile, the touch screen according to the present invention may be configured so as to be kept in an inactive state at a normal time, and to be switched to an active state by a specific operation of the user.

For example, in a normally inactivated touch screen, the liquid crystal panel can be kept in a shielded state, and the lighting means can be turned off. At this time, the touch panel may be configured to detect the occurrence of touch input at a longer period than the active state in the inactive state, or may be configured to respond to a larger threshold value than the active state.

In this deactivation state, when the user sweeps the surface of the touch panel with a finger or palm or touches the palm with a wide touch, the touch screen can be activated.

In the activated state, the liquid crystal panel is switched to the light-emitting state, and the illumination means is operated to display the keypad.

FIG. 2 illustrates the positional relationship between the touch panel, the liquid crystal panel, and the background pad constituting the panel module in the structure of the panel module in the touch screen according to the present invention having the above-described structure. The panel module is shown as being arranged in the order of the touch panel, the liquid crystal panel, and the background pad from the side viewed from the user.

However, at least the touch panel may be disposed between the liquid crystal panel and the background pad or the back of the background pad. Furthermore, it will be further described later through another embodiment, but it is also conceivable that the touch panel is configured not to be added as a separate substrate but to be coupled to the surface of another panel.

Again, in the drawing, the light emitting elements 141 constituting the lighting means are shown as being arranged on the side of the liquid crystal panel. However, the illumination means may be arranged to illuminate the background pads in a different manner at different locations.

Fig. 3 is a sectional view of the panel module having the above-described configuration as viewed from the side. First, there is a touch panel composed of a transparent substrate 111 on which an electrode pattern 112 is formed. The electrode pattern may be formed on the upper surface as shown or on the opposite lower surface. Or a separate protective layer may be additionally formed (not shown).

Next to the touch panel, there is a liquid crystal panel composed of a first transparent layer and a second transparent layer with a liquid crystal layer interposed therebetween.

At this time, it is preferable that the electrode pattern 112, the transparent substrate 111, the first transparent layer 121, and the second transparent layer 123 are all made of a transparent material.

Next, the background pad 130 is disposed. For example, a keypad may be printed on the background pad. The background pad may be an opaque material. Further, the surface on which the keypad is printed on the background pad can be configured to have light reflection characteristics. As a result, when the user looks at the panel module, the shape of the keypad can be seen more clearly.

4 is a view showing another method of configuring the panel module. In the drawing, as described briefly above, the touch panel is not formed as a separate substrate, but an electrode pattern is formed on one surface of the liquid crystal panel so that the liquid crystal panel also functions as a touch panel. According to such a configuration, the cost and process for configuring the touch screen can be reduced.

Furthermore, the electrode pattern may be formed on one side of the background pad.

It is also possible to consider a configuration in which the shape of the keypad to be printed on the background pad is printed on the surface of the second transparent layer. With this configuration, the functions of the touch panel and the background pad can be shared by using only the liquid crystal panel, and the manufacturing cost and thickness of the panel module can be reduced.

FIG. 5 is a view schematically showing a configuration of a door lock device having a transmissive display type touch screen according to the present invention. Here, a door lock device using a touch screen according to the present invention described with reference to Figs. 1 to 4 as a keypad for a user to input a password will be described.

The door lock device includes a panel module for allowing a user to recognize a keypad type and touching a desired password, a control module for detecting a touch generated on the panel module and outputting a password inputted by the user, And a Moris module for switching the door to the locked state or the unlocked state after the processing.

The configuration and operation of the panel module and the control module are as described above.

On the other hand, the Motis module includes a dead bolt driver and an authentication controller.

The deadbolt driver moves the deadbolt forward or backward to switch the door to the locked state or the unlocked state.

The authentication control unit stores a preset authentication password. When the password (user number) input by the user output from the control module is input, the authentication control unit performs an authentication procedure for determining whether the user number matches the authentication password . Then, by controlling the operation of the deadbolt driver in accordance with whether or not each number is matched, the lock state or the unlock state of the door is switched.

In such a door lock apparatus, the touch screen and the motis module can be kept in a deactivated state in a normal state. As described above, the user can activate the touch screen by sweeping down the touch screen or by touching the touch screen with a wide palm. At the same time as activation of the touch screen, at least the authentication control unit of the motis module is activated, can do.

In addition, if the user performs the authentication process for the user number when performing the sweeping operation with the palm after inputting the user number, it is possible to prevent the user from touching the surface of the touch screen , The leakage of the password can be prevented.

In addition, since the illumination of the touch screen can be controlled according to the position where the door lock device is installed and the surrounding brightness, the user is less inconvenient to use the keypad.
