1 An addreng technue for dplayng retrcted pattern n rm-repondng LCD by electng a few row at a tme K. G. Pan Kumar T. N. Ruckmongathan Abtract An addreng technue that wll allow rm-repondng matrx LCD to dplay retrcted pattern propoed. Th technue baed on the electon of a few row at a tme whle cannng the dplay. In applcaton uch a logc analyzer and ocllocope, motly ngle-valued functon of tme are dplayed. Th retrcton n the mage ueful n enhancng the electon rato o that good contrat achevable even wth TN-LCD. It hown that a large reducton n the hardware complexty of the column drver and the upply voltage poble when the waveform beng dplayed do not overlap each other and are eually paced. Keyword Pave-matrx LCD, addreng technue, retrcted pattern, mult-lne addreng. Background A matrx dplay uually degned to dplay general pattern. Hence, t poble to dplay N dfferent pattern n any column of a matrx dplay wth N row. However, mot of thee N combnaton do not occur n dplay for ocllocope and logc analyzer. Shank and Holland have ued the correlaton properte of peudo random bnary euence (PRBS) for dplayng a ngle waveform on a matrx LCD. An nfnte electon rato poble becaue only one waveform dplayed. An addreng technue for dplayng multple waveform on a matrx LCD wa propoed n 986. Th technue baed on cannng the matrx by electng one row at a tme. The electon rato of th technue ndependent of matrx ze and only depend on the number of waveform (w) beng dplayed. In thee dplay the number of elected pxel n each column eual to w. The number of background pxel (N-w) uually much hgher than w. The column voltage for the background pxel choen to be the ame a that for the unelected row. The column voltage for the elected pxel (.e., pont on the waveform) choen to be n-phae wth the row-elect voltage. Th euvalent to agnng data 0 to the background pxel and + to the elected pxel. Here, the rm voltage of elected pxel lower than that of the background pxel. Hence, th technue referred to a the retrcted pattern addreng technue negatve contrat (RPAT-NC). The rm voltage acro each elected pxel can alo be made greater than the background pxel by choong the column voltage for a elected pxel to be out of phae wth the row-elect voltage. Th technue referred to a the retrcted pattern addreng technue potve contrat (RPAT-PC). The electon rato of RPAT are ndependent of matrx ze and are hgher than that of the conventonal technue. 4 Hence, a good contrat rato can be acheved even n LCD wth large matrx ze. Intantaneou voltage acro any pxel n a dplay addreed wth RPAT zero durng mot of the tme nterval, and th may lead to flcker when N very large. The upplyvoltage reurement of RPAT alo ncreae wth matrx ze. In order to overcome thee problem a new flcker-free addreng technue wa propoed n 996. Th technue baed on electng all the row n the matrx dplay multaneouly, a n the cae of actve addreng. 6 Here the N row n the matrx dplay are drven wth waveform correpondng to a et of orthogonal functon derved from PRBS. The column waveform are generated by takng the orthogonal tranform of the data to be dplayed. Here, agan, the data agned to the background pxel zero whle + agned to the elected pxel. Th technue referred to a PRBS-NC. The lower rm voltage uppled to the elected pxel compared to the background pxel. In a mlar technue known a PRBS-PC, the elected pxel receve a hgher rm voltage when the data agned to the elected pxel. A hgher addre duty factor n the PRBS technue reult n the uppreon of flcker and frame repone when N large. The number of tranton n the row waveform almot the ame when orthogonal functon derved from peudo random bnary euence ued. Th reult n a good brghtne unformty of the pxel a compared to that of RPAT. The upply-voltage reurement n the PRBS technue ndependent of the matrx ze, and t lower than that of RPAT. The only dadvantage of PRBS technue that the number of voltage level n the column waveform ncreae wth w a n the cae of dplay n a logc analyzer. In ummary, both lne-by-lne addreng a well a multaneou electon of all the row ha been condered Receved 7//00; accepted 9//00. The author are wth the Raman Reearch Inttute, Lud Crytal Laboratory, Sr C.

2 n the pat for dplayng retrcted pattern. We explored the poblty of electng a few row at a tme. Th approach analogou to mult-lne addreng (MLA) for dplayng general pattern. We have found that t poble to reduce the number of column voltage level when the number of waveform beng dplayed are large. Hence, t poble to reduce the hardware complexty of the column drver n pecal cae uch a dplay for a logc analyzer. Technue In th preent work for dplayng retrcted pattern we have opted to can the dplay by electng a few row at a tme. Th approach for drvng matrx LCD wll be referred to a mult-lne retrcted pattern addreng (MLRPA). Here, the N row to be multplexed n a dplay are dvded nto (N/) non-nterectng ubgroup, wth each ubgroup contng of addre lne. The data to be dplayed n a elected ubgroup n any one of the column an -bt word repreented d k+. Here the value of range from to and the varable k repreent the elected ubgroup and range from 0 to [(N/) ]. By agnng the data for the background pxel to be 0, the electon rato ndependent of matrx ze. Background pxel receve a hgher rm voltage compared to the elected pxel when the data for the elected pxel agned to be +. Th reult n negatve contrat. The dplay exhbt a potve contrat when the data for the elected pxel agned to be. However, the electon rato wll be lower than that for the negatve contrat mode. A n all the retrcted-pattern addreng technue, thee two varant wll be referred to a MLRPA NC and MLRPA PC, repectvely. A et of orthogonal functon are ued for electng a ubgroup of a matrx LCD. Smple orthogonal functon uch a Walh functon are preferred. Let O(,j) be the matrx repreentng the dcrete veron of the orthogonal functon. Here, the element of the matrx O(,j) are jut + or and the followng condton atfed: Â j " m n O( m, j) O( n, j), 0 " m π n wheren the calng factor whch depend on the actual orthogonal matrx elected for cannng the dplay.

A ubgroup elected wth voltage correpondng to one of the row elect pattern. The ampltude of thee voltage ether +V r or V r correpondng to + or n the row-elect pattern.

Smlarly, column voltage for all the column n the matrx are determned ndependently. Both the row and column voltage are appled multaneouly to the matrx dplay for a tme duraton τ.

In applcaton uch a logc analyzer, the waveform generally do not overlap wth each other and are eually paced. One can chooe N/ w, then only one elected pxel wll be preent n each ubgroup. Hence, only two column voltage level (+V c and V c ) are reured. If (N/) > w, then n ome ubgroup none of the elected pxel may be preent.
