Embodiment 1

[0041] This embodiment discloses a Mini-LED dynamic backlight single-line driving method, which supports breakpoint resume transmission, such as figure 1 As shown, this method realizes the routing of a single-layer PCB board and the design of a chip by designing the PCB routing and making a special layout for the power supply and ground routing. Such as figure 1As shown, the Mini-LED includes m rows and n groups of chips. In this embodiment, each group of chips includes x columns, and each column corresponds to a partition, that is, each group includes x partitions, and m, n, and x are all natural numbers.

[0042] Starting from the first group of each row, the signals are transmitted corresponding to the partitions of the chip and transmitted to the corresponding chip of each partition, and m rows are copied based on this, so as to realize the area division of the number of chip rows * chip columns * number of partitions , for the convenience of description, this embodiment ...

Embodiment 2

[0052] When this embodiment supports MINI-LED dynamic backlight single-line drive for breakpoint resume transmission, the connection and driving mode of the chip to the partition is basically the same as that of Embodiment 1. The difference is that the pin design of the chip described in this embodiment is the same as that of Embodiment 1. Example 1 is different.

[0053] Image 6 Shown is a chip with an independent communication protocol involved in this embodiment. The chip has 8 partition-driven chips. PIN pins 1 to 8 are output ports OUT0 to OUT7, and PIN pin 16 is an input pin for resume transmission. ASIN, PIN 15 is the power supply VDD, PIN 14 is the data input SIN, PIN 13 is the ground GND, and PIN 12 is the data output SOUT. In this example, the breakpoint resume function is realized by transferring SOUT across chips.

[0054] Figure 7 Shown is a schematic diagram of the connection between chips in this embodiment. According to the function of the chip and the PCB...

Abstract

The invention discloses a Mini-LED driving method and a display system, belonging to the technical field of Mini-LED driving methods. Aiming at the problems of insufficient Mini-LED backlight area, poor display effect, low system stability, and low service life in the prior art, the present invention partitions the driver chips, and each driver chip corresponds to different partitions of X columns; Each partition works according to the output signal of the driver chip to control the brightness of each partition; when driving, the output signal of the driver chip includes the main signal and auxiliary signal, the main signal is used for signal display when the system is normal, and the auxiliary signal is used for system interruption. When the point is reached, the signal is displayed when the breakpoint is resumed. The invention supports breakpoint resume transmission, has low requirements on the PCB board, and enhances the overall stability and display effect of the system under the condition of reduced cost.

Description

technical field [0001] The present invention relates to the technical field of Mini-LED driving methods, and more specifically, relates to a Mini-LED driving method and a display system. Background technique [0002] In daily life, the frequency of obtaining information from electronic devices such as mobile phones and computers continues to increase, and people's requirements for display devices continue to increase. More delicate, more realistic picture display. [0003] In such a usage scenario, Mini-LED technology has been welcomed by major manufacturers. This technology has been used in many electronic devices. By using Mini-LED technology to control more lamp beads to achieve backlight control, the difference is Because the traditional screen backlight is lit up in its entirety, Mini-LED controls the part that needs to be displayed to light up, and the rest is turned off, so as to achieve higher contrast. The Mini-LED technology avoids the problem that the module tra...
