摘要： A plurality of pixel circuits are provided on a TFT-side substrate 11, light blocking layers 15 and light blocking layer openings 16 are provided between the pixel circuits, and optical sensors 17 are arranged at positions where the light blocking layers 15 are provided. Light blocking layers 18 are also provided at opposing portions of the opposite substrate 12, and light reflecting units 19 are provided correspondingly to the optical sensors 17. In the normal state, backlight BL that has passed through the TFT-side substrate 11 is reflected by the light reflecting unit 19 and falls on the optical sensor 17. When the front surface of the liquid crystal panel is pressed, the two substrates come close to each other, the light reflection direction in the light reflecting unit 19 changes, and the intensity of light detected by the optical sensor 17 changes. By subjecting the obtained sensor image to an image recognition process, it is possible to eliminate the effect of the external light and detect the touch position on the display screen with high accuracy.
摘要翻译：在TFT侧基板11上设置多个像素电路，在像素电路之间设置有遮光层15和遮光层开口16，并且在设置有遮光层15的位置配置有光学传感器17。遮光层18也设置在相对基板12的相对部分处，并且光反射单元19对应于光学传感器17设置。在正常状态下，已经通过TFT侧基板11的背光BL被光反射单元19落在光学传感器17上。当按压液晶面板的前表面时，两个基板彼此靠近，光反射单元19中的光反射方向变化，并且强度由光学传感器17检测到的光改变。通过对获得的传感器图像进行图像识别处理，可以消除外部光的影响并且以高精度检测显示屏上的触摸位置。

摘要： A liquid crystal panel 11 with built-in sensors includes, in a pixel array 18, a plurality of pixel circuits and a plurality of optical sensors arranged two-dimensionally. When the liquid crystal panel 11 is formed of CG silicon, the light receiving sensitivity of the optical sensor is high for blue light but becomes low for red or green light. A display data processing unit 12 corrects a gradation having a value that is less than or equal to a predetermined value, to high for a blue component contained in display data D1. The display data processing unit 12 corrects only data displayed in a recognition area set in a display screen out of the blue component. Thus, even when the display image is dark, it can be converted to an image easy to recognize, a touch position can be detected properly irrespective of the display image, and a change of the display image by correction can be limited to the change of a specific color in a specific area.

摘要： A liquid crystal panel with built-in sensors 11 includes, in a pixel array 17, a plurality of pixel circuits 1 and a plurality of optical sensors 2 which are arranged two-dimensionally. Infrared light transmitting filters 3 that allow infrared light to pass therethrough and cut off visible light are respectively provided in paths of light entering the optical sensors 2. Accordingly, an image obtained by the optical sensors 2 is prevented from being influenced by visible light included in outside light or backlight light and thus a touch position is detected with high accuracy, based on an image that is not influenced by visible light included in a large amount in outside light or backlight light. Instead of the infrared light transmitting filters 3, a light-shielding film having the same property 3 may be used.
