Zusammenfassung: | To provide a liquid crystal display device capable of accurately measuring the temperature.SOLUTION: A liquid crystal display device 1 includes: an image display portion having a plurality of pixels arranged in a two-dimensional matrix shape; a horizontal shift register that sequentially takes in a plurality of video signals for the number of columns of the plurality of pixels; a latch circuit that outputs, all at once, the plurality of video signals taken in by the horizontal shift register; a signal processing circuit that converts each of the plurality of video signals output from the latch circuit into a plurality of analog signals; a vertical shift register that controls so that the signal processing circuit enables the plurality of analog signals to access the plurality of pixels arranged in a row of any one of the plurality of pixels; and a temperature measuring circuit. The temperature measuring circuit has a temperature sensor and measures the temperature of the liquid crystal display device on the basis of a detection result by the temperature sensor in a period in which power consumption of the liquid crystal display device is a predetermined power level or less.SELECTED DRAWING: Figure 1
【課題】精度良く温度を測定することが可能な液晶表示装置を提供すること。【解決手段】液晶表示装置1は、2次元マトリクス状に配置された複数の画素を有する画像表示部と、複数の画素の列数分の複数の映像信号を順次取り込む水平シフトレジスタと、水平シフトレジスタによって取り込まれた複数の映像信号を一斉に出力するラッチ回路と、ラッチ回路から出力された複数の映像信号のそれぞれを複数のアナログ信号に変換する信号処理回路と、複数の画素のうちの何れかの行に配置された複数の画素への、信号処理回路による複数のアナログ信号のアクセス、が可能になるように制御する垂直シフトレジスタと、温度測定回路と、を備えた、液晶表示装置であって、温度測定回路は、温度センサを有し、液晶表示装置の消費電力が所定電力以下となる期間における温度センサによる検出結果に基づいて、液晶表示装置の温度を測定する。【選択図】図1 |
