Therefore, in such a configuration, since lighting must be prioritized in order to use the touch screen, the power consumption is large. In addition, since the illumination is made from the back of the light-transmitting sheet, the thickness of the touch screen is inevitably thick because the thickness for the electronic device for illumination must be secured.

In this case, the liquid crystal panel is switched to a light transmitting 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 having the electrode pattern may be configured to simultaneously perform the function of the touch panel.
In addition, the shape of the keypad to be printed on the background pad may be printed on the surface of the first transparent layer or the surface of the second transparent layer of the liquid crystal panel.

1 is a view schematically showing the configuration of a transmissive display touch screen according to the present invention. Referring to the drawings, a transmissive display touch screen according to the present invention comprises 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 may perform a corresponding function by the touch sensing function unit, the liquid crystal control function unit, and the illumination control function unit. On the other hand, the touch screen according to the present invention may further have a lighting means and a brightness sensor.
The panel module provides a keypad on which at least two numbers or symbols are displayed and outputs an electrical signal corresponding to a position touched by a user's finger. The control module analyzes the electrical signal output from the panel module to determine which key or symbol the user wants to input by touching a 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 by printing or coating. The structure of such a touch panel can use that of a general touch device. In addition, the touch panel may be applied to any sensing method, such as a capacitive sensing method, a pressure sensing method, and the electrode pattern formed according to this may also vary.
The liquid crystal panel is optically provided by an electrical signal (that is, a control signal) which is inserted and input into a gap between the first transparent layer and the second transparent layer of transparent material superimposed at predetermined intervals and the overlapping first transparent layer and the second transparent layer. It includes a liquid crystal layer in which the characteristics are changed to switch between light transmission and light shielding.
In such a liquid crystal layer, the alignment state and the non-alignment state may be switched according to whether a control signal is applied, and thus light emission and light blocking may be controlled. The structure and operation of such a liquid crystal layer can be understood with reference to, for example, a liquid crystal panel known from Korean Patent Laid-Open Publication No. 2013-10066 (name: contrast window).
The background pad is visually printed in any form. In this case, the printed form may be, for example, a form of a keypad including at least two numbers or symbols. In general, the keypad is displayed in a 3x4 arrangement of ten numbers and two symbols (see Figure 2). Alternatively, in the background pad, numbers or symbols may be displayed in another manner, for example, dialing or randomly arranged.
Next, in the control module, the touch sensing function unit detects a position where a finger touch occurs in the touch panel by driving the touch panel. The detected touch position is printed on the background pad and associated with the position of each designated number or symbol to determine which number or symbol the user wants to touch, and outputs touch information indicating the number or symbol. The output touch information may be provided to another electronic device or may be provided to a Mortis module to be described later.
The liquid crystal control function unit controls light projection and 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 for the panel module. In the touch screen according to the present invention, the panel module may further include lighting means, and the light control function controls the operation of the lighting means. In addition, the touch screen according to the present invention may further include a brightness sensor, and may sense the brightness of the surroundings by the brightness sensor and control the on / off or the light intensity of the lighting means according to the detection result.
The lighting means illuminates the background pad so that when the liquid crystal panel in the panel module operates in the transmissive state, the printed form of the background pad is more visible to the user. To this end, the lighting means may comprise one or a plurality of light emitting elements (for example, a light emitting diode; see FIG. 2), which may be arranged, for example, in the side of the liquid crystal panel. It can be arranged to emit illumination light toward. When the light emitting device is disposed in this way, the emitted illumination light may be substantially uniformly emitted from all surfaces while being reflected inside the surface of each light transmitting layer in the first light transmitting layer or the second light transmitting layer constituting the liquid crystal panel. It is possible to illuminate the surface of the rear keypad as a whole generally uniformly.
Meanwhile, the touch screen according to the present invention may be configured to remain in an inactive state during normal times, and to be switched to an activated state by a specific operation of the user.
For example, in a normally inactive touch screen, the liquid crystal panel may be kept in a light shielding state, and the lighting means may be turned off. In this case, the touch panel may be configured to detect the occurrence of the touch input every longer period than the activation state in the inactive state, or may be configured to respond to a threshold greater than the activation state.
In such a deactivated state, if the user swipes the surface of the touch panel with a finger or palm or touches the palm wide, the touch screen may be switched to an activated state.
In the activated state, the liquid crystal panel is switched to the transmissive state and the illuminating means is operated to show the keypad.
FIG. 2 illustrates the structure of a panel module in the touch screen according to the present invention having the above-described configuration, and shows the positional relationship between the touch panel, the liquid crystal panel, and the background pad constituting the panel module. The panel module is illustrated as being arranged in the order of the touch panel, the liquid crystal panel, and the background pad from the side viewed by the user.
However, at least the touch panel may be disposed between the liquid crystal panel and the background pad or behind the background pad. Moreover, as will be described later through another embodiment, it is also conceivable that the touch panel is not added as a separate substrate, but is configured in such a manner as to be coupled to the surface of another panel.
Again, in the figure, it is shown that the

After the touch panel, there is a liquid crystal panel composed of a first transparent layer and a second transparent layer having a liquid crystal layer interposed therebetween.
In this case, the
Next, the
4 is a view showing another manner of configuring a panel module. In the drawing, as briefly described above, the touch panel is not configured as a separate substrate, but an electrode pattern is formed on one surface of the liquid crystal panel, thereby showing a configuration in which the liquid crystal panel functions as a touch panel. According to this configuration, it is possible to reduce the cost and the process of configuring the touch screen.
Furthermore, the electrode pattern may be formed on one side of the background pad.
Also, a configuration may be considered in which the form of the keypad to be printed on the background pad is printed on the surface of the second transparent layer. By such a configuration, only the liquid crystal panel can be used as a function of the touch panel and the background pad, and the manufacturing cost and thickness of the panel module can be reduced.
5 is a view schematically showing the configuration of the door lock device having a transmissive display touch screen according to the present invention. Here, a door lock device using the 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 recognizes a keypad form and touches a desired password to input a panel module, a control module for detecting a touch generated on the panel module to output a password input by the user, and receives and authenticates the output password. It includes a Mortis module that switches the door to a locked or unlocked state after processing.
The configuration and operation of the panel module and the control module are as described above.
On the other hand, the Mortis module includes a dead bolt driver and an authentication controller.
The dead bolt drive unit moves the door to the locked state or the unlocked state by advancing or retracting the dead bolt.
The authentication control unit stores a preset authentication password, and when a password (user number) input by a user output from the control module is input, the authentication controller performs an authentication procedure for determining whether the user number matches the authentication password. . Then, by controlling the operation of the dead bolt driving unit in accordance with whether or not each number matches, the locked state or unlocked state of the door is switched.
In such a door lock device, the touch screen and the Mortise module can be kept in an inactive state in the usual state. As described above, the user may activate the touch screen by swiping the touch screen or touching the palm wide, and at least the authentication controller of the Mortis module is activated at the same time as the touch screen is activated, thereby waiting for the user authentication procedure. can do.
In addition, when the user enters the user number and then swipes it with the palm of the hand, if the user is configured to perform the authentication process for the user number, the trace of the user's touch on the surface of the touch screen can be prevented. This can prevent the leakage of passwords.
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 ambient brightness, the user has little inconvenience in using the keypad.
