Filed: 1993-12-01
Abstract: PURPOSE:To suppress the rate of temperature variation in an output value from an amplifier by respectively setting up the temperature characteristics of constant current circuits on odd and even numbered stages in the pre-group of amplifiers connected in cascade as the square of temperature and a fixed value and setting up the current characteristics of constant current circuits in the post group in proportion to the temperature itself. CONSTITUTION:Differential amplifiers DA1 to DA2n on 2n stages including constant current circuits C11 to C12n are connected in cascade so that a differential output from a pre-stage is supplied as a differential input to the succeeding stage. The common emitter terminal of the amplifier DA2 on the 2nd stage is inputted to the base terminal of a transistor(TR) ATr1, 1 in an adding differential amplifier ADA1. On the other hand, reference voltage E01 is inputted to the base terminal of a TR ATr1, 2. Similarly the common emitters of even numbered stages are connected to adding amplifiers. Currents flowing into constant current circuits on odd numbered stages from the 1st stage up to the 2j-th stage (where, 1<=j<n) out of the 2n stages of differential amplifiers are controlled so as to be proportional to the square of temperature and currents flowing into constant current circuits in odd and even numbered differential amplifiers from the 2k-th (where, j<k<=n) up to the n-th stage out of 2n stages of differential amplifiers are controlled so as to proportional to the temperature itself.

Title: Display device
Inventor: NIIZAWA TADASHI
IPC: G09G3/296
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a display device that unnecessary reductions of the luminance of display elements are prevented without enlarging the size of a power source device. SOLUTION: Relating to this device, a display control device 21 makes display elements to be lighted with corresponding luminance by making constant currents having corresponding current values to be supplied to respective display elements while making duty ratios to be changed by controlling pulse widths based on luminance data for every display element of respective display units 7. When the luminance of the display elements is low, it is prevented that the luminance of the display elements go out because of small currents by raising a voltage. Moreover, when the luminance of the display elements is high, since current values are high and the luminance of the elements hardly go out, the capacity of the power source of a power supplying means is suppressed small by lowering the voltage.  Then, since values of currents are constant, even when the value of the voltage is controlled, the luminance of the display elements can be made constant.
