Abstract

The planar display includes base board, pixel matrix, the first DC / DC converter and the second DC / DC converter. The pixel matrix is formed on the base board. The first DC / DC converter is located inside the integrated circuit to provide the integrated circuit with required power sources while outputting one output voltage. The second DC / DC converter is formed on the base board and connected to the first DC / DC converter for converting the output voltage into the operation voltage for the grid driver.

Description

technical field

[0001] The present invention relates to a flat-panel display, and in particular to a flat-panel display in which a part of the voltage converting circuit of a DC-DC converter (DC-DC Converter) of an original integrated circuit is disposed on a substrate. Background technique

[0002] figure 1 It is the square diagram of the first liquid crystal display of the existing mobile phone. Please refer to figure 1 , the liquid crystal display 100 of the mobile phone is, for example, a low temperature polysilicon (Low Temperature Poly-silicone, LTPS) liquid crystal display, which includes an integrated circuit 110 , a substrate 120 , a gate driver 122 , a data driver 124 and a pixel matrix 126 . The integrated circuit 110 includes a DC-DC voltage converter 112 , a source driver 116 and a Vcom driver 118 . The voltage converter 112 is used to convert the system voltage Vcc (approximately 2.7V-3V) into an operating voltage Vs (approximately 5V) to provide the operati...
