Pen writing display panel and display device

Abstract

The invention discloses a pen writing display panel and a display device, and relates to the technical field of displaying. The pen writing display panel comprises a display area and a non-display area surrounding the display area, wherein the display area comprises an opening area and a non-opening area; the pen writing display panel includes a first substrate, a plurality of gate lines, a plurality of data lines, a light shielding layer, a photoelectric identification unit and a light transmitting unit; the plurality of gate lines extend along a first direction and are arranged along a second direction, the plurality of data lines are arranged along the first direction and extend along the second direction, the gate lines and the data lines are both located in the non-opening area, andthe first direction intersects with the second direction; the light shielding layer is positioned in the non-display area and the non-opening area; the photoelectric identification unit is positionedon one side, facing the light emitting surface of the pen writing display panel, of the first substrate, is positioned in the non-opening area and comprises a light sensing unit; the light transmitting unit corresponds to the light sensing unit, is positioned in the light shielding layer and is positioned in the non-opening area; the orthographic projection of each light transmitting unit to a plane on which the first substrate is located is overlapped with the orthographic projection of the light sensing unit to the plane on which the first substrate is located. Thus, the pen writing function is realized.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a pen display panel and a display device. Background technique [0002] From the era of CRT (Cathode Ray Tube, cathode ray tube) to the era of liquid crystal, and now to the era of OLED (Organic Light-Emitting Diode, organic light-emitting diode), the display industry has experienced decades of development and has become ever-changing. The display industry has been closely related to our lives. From traditional mobile phones, tablets, TVs and PCs to the current smart wearable devices and VR, display technology is inseparable. [0003] With the development of display technology, the display industry has gradually expanded to the field of pen display similar to electronic blackboards. However, in the prior art, the handwriting display technology similar to the electronic blackboard is not mature, and it is difficult to realize handwriting writing in a real sense,...
