Embodiment Construction

[0013] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

[0014] figure 2 is a diagram showing the components of the portable DVD player according to the present invention. Such as figure 2 As shown, it consists of the following parts: light sensing device 210; variable resistance device 230; signal selection device 250; conversion device 270;

[0015]

[0016] The light sensing device 210 outputs a light information signal corresponding to the brightness of the peripherals of the portable DVD player. The light sensing device 210 according to the present invention includes a light sensor. The output voltage of the light information signal can be adjusted according to the brightness of the light input by the light sensor.

[0017]

[0018] The variable resistance device 230 may output a resistance value information signal corresponding to the resistance value after the resist...

Abstract

The invention relates to a portable DVD player, which specifically refers to the DVD player that can regulate the brightness of the display device according to the brightness of the peripheral equipment. The DVD player includes: a light-sensor (a) used to output the relative brightness signals of the corresponding peripheral equipment, a converting device (b)used to output the regulating signals corresponding to the brightness signals and a LCD panel (c) of the backlight device used to output the brightness corresponding to the regulating signals from the converting device. So the sensor equipment can automatically adjust the brightness of the LCD according to the peripheral brightness.

Description

【Technical field】 [0001] This invention relates to portable DVD players. Specifically, it relates to a portable DVD player capable of adjusting the brightness of a display device according to the brightness of peripheral equipment. 【Background technique】 [0002] Today, with the widespread popularization of DVD (Digital Video Disc) equipment supporting high-definition and stereophonic sound, portable DVD players with excellent mobile performance are gradually being favored by people. [0003] figure 1 It is a diagram showing the components of a conventional portable DVD player. refer to figure 1 It can be seen that the variable resistor 130 is connected to the input terminal of the converter 120 . An output terminal of the converter 120 is connected to a terminal of a back light of the TFT LCD panel 110 . [0004] The user can manually adjust the variable resistor 130 . Then, when the value of the resistance changes, a resistance value information signal corresponding ...
