摘要： A display panel includes an array substrate, an opposite substrate and a liquid crystal layer disposed between the array substrate and the opposite substrate. A sensing array outputs an initial voltage in response to an initial thickness of the liquid crystal layer during an initializing time and a sensing voltage in response to a varied thickness of the liquid crystal layer due to external force during a sensing time. A control part compares the sensing voltage with the initial voltage, determines whether the external force is applied to the display panel, and generates information indicating a position to which the external force is applied. Thus, the display apparatus may improve sensing ability to an external signal inputted through the display panel thereof.
摘要翻译：显示面板包括阵列基板，相对基板和设置在阵列基板和相对基板之间的液晶层。感测阵列响应于在初始化时间期间液晶层的初始厚度和响应于在感测时间期间的外力而导致的液晶层的厚度变化的感测电压而输出初始电压。控制部分将感测电压与初始电压进行比较，确定外力是否施加到显示面板，并产生指示施加外力的位置的信息。因此，显示装置可以提高通过其显示面板输入的外部信号的感测能力。

摘要： A shift register includes a plurality of stages each generating an output signal in sequence and including a buffering section, a driving section, a first charging section, and a charging control section. The buffering section receives one of a scan start signal and an output signal of a previous stage so that the driving section generates the output signal of a present stage. The first charging section includes a first terminal electrically connected to the driving section and a second terminal electrically connected to a first source voltage. The charging control section applies the output signal of a next stage to the first charging section. Therefore, a gradual failure of TFT is reduced.

The lower substrate is divided into a display region for displaying an image and an adjacent peripheral region, and includes a plurality of pixel parts, a plurality of photo sensing parts, and a reflection preventing layer. The pixel parts are disposed in the display region for forming an image. The photo sensing parts are disposed in the display region for detecting the location of an object placed on or immediately adjacent to a surface of the display panel. The upper substrate faces the lower substrate, and includes a black matrix corresponding to the peripheral region. The reflection preventing layer is disposed in the peripheral region to prevent the black matrix from reflecting light back onto the photo sensing parts and thereby adversely affecting their operation.

摘要： A shift register includes stages to generate gate signals in sequence. Each of the stages includes a first pull up drive control section, a pull up drive section and a pull down drive section. The first pull up drive control section outputs a control signal based on the gate signal of an adjacent stage. The pull up drive section receives a first clock signal and outputs the first clock signal as the gate signal to a corresponding gate line in response to the control signal. The pull down drive section inactivates the corresponding gate line in response to a second clock signal.
