摘要： A conductive pattern structure is provided by the embodiment of present disclosure. The conductive pattern structure (20) includes: a first metal pattern (201) and a second metal pattern (202). The second metal pattern (202) covers at least a portion of a side surface of the first metal pattern (201); and an activity of a metal material of the first metal pattern (201) is weaker than an activity of a metal material of the second metal pattern (202). The embodiment of present disclosure prevents the side surface of the first metal pattern (201) from being oxidized by forming the second metal pattern (202) covering at least a portion of the side surface of the first metal pattern (201), in this way, the problem that the electrical conductivity of the first metal pattern (201) reducing is avoided, and the problem that the product yield declining is avoided. In addition, the present disclosure further reduces the requirements for the production equipment and the external environment, in this way, the complexity of the manufacturing process of the conductive pattern structure is reduced and the production cost is reduced.

摘要： A grating, a manufacturing method of grating and a display device are disclosed. The grating comprises a first substrate (21) and a second substrate (22) which are oppositely disposed; a first transparent electrode (23) which has a grating structure and is disposed on a side of the first substrate (21) facing towards the second substrate (22); a second transparent electrode (24) which is disposed on a side of the second substrate (22) facing towards the first substrate (21) and is disposed to be opposite to the first transparent electrode (23); and a polymer layer (25) which is disposed between the first transparent electrode (23) and the second transparent electrode (24), the polymer layer containing therein nano-sized material converting electromagnetic energy into heat energy and liquid crystalline elastomers. When a voltage is applied between the first transparent electrode (23) and the second transparent electrode (24), the nano-sized material converts electromagnetic energy into heat energy, so that the polymer layer (25) is in cholesterol phase and reflects all the light within the wavelength range of visible light; and when no voltage is applied between the first transparent electrode (23) and the second transparent electrode (24), the polymer layer (25) is in transparent state. The grating is configured to be used with a display panel to achieve naked-eye 3D display and reduce light transmission loss at the time of 2D display.

摘要： The present disclosure discloses a circuit and method for generating a light emission control signal for an AMOLED pixel circuit having in-cell touch sensors, as well as a pixel circuit driving method. The circuit comprises a first transistor T1, a second transistor T2, a third transistor T3, a fourth transistor T4 and a first capacitor Cg. Under control of a control signal transferred by a first control line GO, a first clock signal CK, a second clock signal CB, a voltage of a first level VGH, a voltage of a second level VGL and a control signal transferred by a second control line VGL_1, the circuit outputs the desired light emission control signal via a light emission control line EM. The light emission control signal may turn off the OLED in the pixel circuit during a touch sense phase such that an influence of the capacitance between the anode and cathode of the OLED on the touch sensor-to-ground capacitance is reduced.

摘要： The present disclosure discloses an in-cell touch screen panel, a driving method thereof and a display device. A plurality of sub-pixels are grouped into sub-pixel groups, each of which includes at least two sub-pixels. Cathode layers of different sub-pixel groups are independent of one another. The cathode layers are reused as self-capacitance electrodes. A driving chip determines a touch position by detecting a change in capacitance of the cathode layers, thereby achieving touch control functionality. The driving chip outputs, in a fourth phase, signals to the cathode layers and to the signal terminals of each sub-pixel circuit, each of the signals is a superposition of the signal output in a third phase with a touch scanning signal such that each sub-pixel circuit operates in the fourth phase in the same state as in the third phase. Thereby the capacitance of the self-capacitance electrodes remains unchanged before and after application of the touch scanning signal in the case that the touch screen panel is not touched by a human body.
