Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] In the embodiment of the present invention, the software upgrade of the logic control board will be realized through the communication between the signal processing board and the logic control board. The following I will be preset in the logic control panel 2 C register port: register REG1 for storing the software version number, register REG2 for receiving sleep mode commands, register REG3 for receiving commands to erase software storage units, register REG4 for storing erase completion flags, register REG5 for temporarily storing upgrade software data, The register REG6 that stores the s...

Abstract

The invention is suitable for the technical field of the television, and provides a method for upgrading plasma television logic control panel software. The method comprises the following steps: a signal processing panel reads software to be upgraded from external equipment via a USB (Universal Serial Bus) or a network port and stores the software; the signal processing panel respectively reads the version number of the software to be upgraded and the version number of the software in the logic control panel and compares whether the two version numbers are same or not; if so, an upgrading program stops, and if not, an upgrading stage is entered; the signal processing panel controls the logic control panel to enter a dormant state and controls the logic control panel to erase the software in a main storage unit; after the software is erased, the signal processing plate transmits the stored software to be upgraded to the logic control panel; the logic control panel programs the software to be upgraded into the main storage unit; the signal processing panel and the logic control panel respectively make statistics on the transmitted software data volume and the programed software data volume; the signal processing panel compares whether the two statistical values are same or not; if so, the process of upgrading is successful; otherwise, whether upgrading is carried out again is manually selected.

Description

technical field [0001] The invention belongs to the technical field of televisions, in particular to a method for upgrading the software of a logic control board of a plasma television. [0002] Background technique [0003] The signal processing system of the plasma (PDP) TV set includes two parts: a signal processing board and a logic control board. Between the signal processing board and the logic control board through LVDS and I 2 C bus connection, communication, such as figure 1 shown. The signal processing board receives audio and video signals of various formats, processes them into standard LVDS signals carrying image information and transmits them to the logic control board, and can read external data through USB ports, network ports or other ports. The logic control board is responsible for receiving and processing the LVDS image signal transmitted by the signal processing board and passing through the I 2 The control signal transmitted by the C bus, and the l...
