摘要： Optical glass, a preparation method thereof, a backlight module and a display module. The optical glass comprises a glass substrate and optical masterbatches, which are dispersed in the glass substrate, each optical masterbatch comprises a quantum dot fluorescent agent inner core and an encapsulation shell which encloses the quantum dot fluorescent agent inner core. A quantum dot fluorescent agent is protected by the encapsulation shell and the luminous efficiency is high; when the optical glass is applied to a display module, the color gamut may be improved; moreover, the glass is capable of preventing against the invasion of water vapor, even the quantum dot fluorescent agent at an edge of the glass rarely fails, and an edge failure size is basically avoided; meanwhile, the expansion coefficient is small, and an expansion space reserved during assembly is extremely small.

摘要： The present disclosure provides a display device and a splicing screen, relating to the field of display equipment. The display device includes a liquid crystal display screen, a lamp board, and a printed circuit board. The lamp board includes a flexible circuit board and a plurality of light-emitting diodes. The flexible circuit board includes a first part and a second part connected to each other. The light-emitting diodes are disposed on the first part, and the first part is disposed on an edge of a front surface of the liquid crystal display screen. The second part extends outside of the liquid crystal display screen to a rear surface of the liquid crystal display screen and is detachably plugged into the printed circuit board disposed on the rear surface. Since the first part is disposed on the edge of the front surface of the liquid crystal display, a picture displayed on the light-emitting diodes can block an edge region of the liquid crystal display screen. Therefore, when a plurality of display devices is spliced into a splicing screen, split seams can be reduced or even eliminated, thereby improving visual effect.

摘要： A tiled display apparatus includes a main display driving board and display modules. Each display module includes a system board. The main display driving board is coupled to a first stage system board. The main display driving board is configured to receive a display signal, acquire a main screen region display signal, and transmit the main screen region display signal to the first stage system board. The system board is configured to receive the main screen region display signal, and extract a group of main screen region display data corresponding thereto from the main screen region display signal to control a display module to which the system board belongs to display an image according to the main screen region display data. Except for a last stage system board, remaining system boards are each further configured to transmit the received main screen region display signal to a next stage system board.

摘要： A light emitting module and a display module. The light emitting module includes a light source (112) assembly (11); the light source (112) assembly (11) includes a substrate (111) and light sources (112), and the light sources (112) are located on the substrate (111). The substrate (111) includes a first area (Q1) and a second area (Q2), the first area (Q1) surrounds the second area (Q2), and the light emitting surfaces of the light sources (112) located in the first area (Q1) are inclined and face the second area (Q2). With the light emitting module, the light emitted by the light sources (112) located at the edge can be inclined toward the center of the light emitting module, which can reduce the light at the edge of the light emitting module, thereby reducing the light leakage phenomenon at the edge of the light emitting module, which is beneficial to improve the display quality.
