Abstract:
A transfer relief plate (02) comprises a base plate (021) which is divided into four regions having identical areas by a first axis (x) and a second axis (y). A plurality of strip-like protrusions are disposed on the base plate (021) and there is an interval between any two adjacent strip-like protrusions. The first axis (x) is in parallel with a stretching direction (x1) of the transfer relief plate (02), and the second axis (y) is in parallel with a non-stretching direction (y1) of the transfer relief plate (02). The plurality of strip-like protrusions comprise a first strip-like protrusion (022) which is disposed in any one of the four regions. An end of the first strip-like protrusion (022) close to a first side (g) of the base plate (021) is inclined to a central direction of the first side (g) of the base plate (021), the first side (g) of the base plate (021) being a side of the base plate (021) which is in parallel with the stretching direction (x1) of the transfer relief plate (02) and is close to the first strip-like protrusion (022). The transfer relief plate (02) improves uniformity of the printed PI solution.

The embodiments of the present disclosure relate to an AMOLED device and a fabricating method thereof, and a display apparatus. The AMOLED device comprises: a back plate; a blue hole transport layer on the back plate; an excitation layer on the blue hole transport layer; a blue light emitting layer on the excitation layer; an electron transfer layer on the blue light emitting layer; and a cathode on the electron transfer layer. The excitation layer is excited by a circuit signal of a device to emit ultraviolet light, and the photochromic material is further excited by the ultraviolet light. The blue light emitting layer displays different chromas under different excitation energies. This manner effectively improves the luminous efficiency of the blue light emitting layer, and extends the color gamut to be adaptive to different display environments, thereby improving the display quality.
Abstract:
A shift register, a gate driving circuit, a display screen and a method for driving the display screen are proposed. A first and/or a second node control unit are incorporated. The first node control unit controls a first node according to a first control signal to put a pulling-up unit in an OFF state; the second node control unit controls a second node according to a second control signal to put a pulling-down unit in an OFF state. During the period that the display screen is powered off, the level at the driving signal output terminal is prevented from being affected by the pulling-up unit through the first node control unit and by the pulling-down unit through the second node control unit, such that thin film transistors connected to a gate line corresponding to the shift register are all turned on and thus accumulated charges can be released rapidly.

Abstract:
An in-cell touch screen and display device, which multiplex the common electrode layer as self-capacitance electrodes using self-capacitance principle, modify the pattern of the common electrode layer to segment it into a plurality of independent self-capacitance electrodes, and add on the array substrate touch control data lines that connect the respective self-capacitance electrodes to the touch control detection chip. Orthographic projections of the respective touch control data lines on the array substrate are all within areas where gaps between the pixel areas reside, so as to not affect the aperture ratio of pixel. Embodiments of the present invention modify the structure of the common electrode layer to segment it into self-capacitance electrodes, thus avoiding additional processes of manufacturing an array substrate, saving the production cost, and improving the production efficiency.
